- Explorer 300 Portable Power Station,292Wh | Backup LiFePO4 Battery, Solar Generator for Outdoors, Camping, Travel, Hunting, Blackout (Solar Panel Optional)

It's been 3onths using the 300 Jackery. It's been just asAdvertised. Charges with adapter plug in about 3 hours. Charges everything I throw at it. Of course your not gonna power your fidge or A/C. As for charging electronics and daily mobile devices quickly this thing it tops. I plan to use it near daily just because plugs in my house are not abundant. Happy guy with a reliable chargering device that.carries very easy. Like a oversized lunchbox!. Id buy agian - next time gonna be the Big boy.

I’m a 100% full time single parent with 2 teens. And with teens you know that means a lot of electronic devices. I need things that work and things that simplify my life. The Jackery 300 has been one of those purchases. It’s not only reliable but really easy to use. Most power outages are not very long lasting. So, I didn’t want to fool with a generator. I imagined how I’d have to check a generator every month. The maintenance. Wheeling the heavy unit around. Getting & storing fuel. Having enough fuel. Making sure the fuel lasts. Struggling to pull start it. The fumes from running it. The loud noise when it actually does run. Not to mention, an easy thousand plus bucks to buy one. All that seems overwhelming for more than 99% of our needs. If the power goes out, no stress, we just grab the Jackery. It’s practically silent and light enough to move around by just about anyone. Is the Nintendo Switch low? No problem. Your Chromebook? Want to run the PS4 or Xbox One? No worries. Your phone, watch, tablet - again - zero stress - just plug it in. Wa-la, problems fixed. It can run fans and a whole host of other devices too - not just your typical tech electronics. During tests, we ran our cable modem / router for many hours to provide WiFi. It accepts regular wall socket type plugs too. Also during our tests, it ran a 55” inch TV along with a PS4 Pro for over 1.5 hours. We even used a disc based game to use even more power. With a smaller screen it’s closer to 2.5 hours. Downloaded games use less power too. The Nintendo Switch uses even less. All that exceeded my expectations. SUPER EASY. Now let’s talk camping, car trips and other family outings. Again, the Jackery 300 is clutch. There’s no need to be concerned about limited outlets in the car to charge or none available at a park or campsite. If I’m going camping - this will always come with us. How nice to run a fan inside the tent during the summer nights! This will instantly get you “glamping”. Tons of options here. The Jackery 300 is also fairly compact and lightweight and weighs in right around 7 1/4 pounds. It’s significantly smaller than the size of a small Igloo Playmate Cooler that I have used as a lunchbox for years. I appreciate that’s it’s powerful but doesn’t take up much space. It’s interface is solid and super easy to understand. All around it’s very intuitive and you can tell everything is very well thought out. It also has you covered with a wide variety of plugs from AC outlet sockets to a car power port to USB-A and the newer USB-C. It even comes with a quality zipper pouch to store your charging cables. Another thing about Jackery is it’s a widely recognized brand with a proven quality track record. Many no name brands are out there that don’t include the device and circuit protections Jackery units do. The last thing I want to do is buy another power station after frying our expensive electronics. I am a believer that when you buy cheap, you often buy twice. This is the top brand in this category of products. I definitely don’t have time to mess with low quality el cheapo brand units. Without boring you with detailed specs, the Jackery 300 produces a very clean stream of power - which is exactly what you want. In layman’s terms, it’s a smooth stream without all the peaks, valleys and surges that can harm your devices. One thing we tend to forget until something happens is what we have on hand for emergencies. This is definitely on my list. If we need to evacuate for any number of reasons (storms, fires, Godzilla - the weirdness of 2020) the Jackery 300 is a must take item. Those in the Prepper, Bug Out and Emergency Preparedness minded communities should be all about this. It can even be fully recharged in just a few hours with the optional Solar Saga solar panel. It can of course be recharged too by your standard home outlet or even your car - and it doesn’t take forever to do it. It also doesn’t alert everyone far and wide that you have power. That might be handy while in a non permissive environment or even a noise restricted campsite. In today’s age and with everything going on, this should really be a staple device in our homes. I feel better just knowing it’s on hand. It’s one less thing to worry about. Lastly, I plan on buying another for my senior citizen mother too. That alone should say a lot! TLDR: Zero regrets with this purchase. It’s an absolute no-brainer.

We camp a lot and also have a cruising boat. This is a must-have for both environments. Compact, seems well made, holds its charge well. The bigger sizes will give you more power, but this is great for charging phones and iPads. We went camping recently for a week and it charged two phones all week without needing to be plugged back in.

[Update: Jackery announced on 1/28/2021 that the updated Explorer 300 can now be charged through the 60W USB-C PD and be used in parallel with the 90W AC wall charger. This provides for a combined input of 150W, nearly cutting the charging time in half!] Back in April, I purchased the Jackery Explorer 1000 and the Goal Zero Yeti 500x later as a result of 2019's fires. Coincidentally, this year's fires on the entire US west coast is actually WORSE with new records broken! I cannot stress how important it is to be prepared for emergencies, and with a baby and young boy in our household, I wanted to ensure we have a crucial refrigerator running to store milk, medication, and whatever else we needed. There has been an increase in people taking emergency preparation more seriously. I had since invested in several car freezers (favorite is the Foho 34qt BCD-32) as part of my emergency toolset. When Jackery announced the Explorer 300 (E300) with a special launch price and some improvements over the Explorer 1000 (E1000), I jumped on it for one simple reason: my little boy loves camping, and I wanted him to have a mini-Explorer of his own (actually, I wanted another backup battery, but don't tell him that.) Literally, the E300 is a mini version of the E1000, and it looks awfully cute to have my son and I stand next to one another holding our own Explorers! Right off the bat, the two models are very similar to one another, and so I will be re-using much of what I had already written for the Explorer 1000. The E300 is the direct successor to the company's Explorer 240 model. CELL MANUFACTURERS Today's devices use Lithium-ion (Li-ion) and Lithium Iron Phosphate (LiFePO4) cells so they can pack more power in a smaller package and weigh less. However, Li-ion (which the Jackery is made with) also is more volatile whose risk increases as more cells are packed together. The quality of the battery cells and the BMS (Battery Management System) are crucial for safety. - Battery storage capacity is measured in Wh, and power output is in W (Watts) - The higher the Watt-hour (Wh) capacity rating, the more dangerous the battery could become if not handled right Battery cells made by LG and Sony are among the best in the hobbyist world as are Sanyo/Panasonic, Samsung, and BAK Battery. Jackery Explorer 1000's batteries are made by LG and BAK, but the E300's are by EVE Battery. I do not have much information about the new, publicly-traded manufacturer's safety record, however, but going by Jackery's track record, they likely would not have selected a poor company to provide fuel cells for their power stations. During my years of research, I found that use of lower-quality batteries could pose a serious risk to life and property and should become a crucial part in deciding what to buy. IN A NUTSHELL Jackery Explorer 300 is a relatively light power station with a professional-looking exterior and flashy, orange color scheme, and is backed by a company that appears, from the stories I have read (and personally experienced), to take customer service seriously. The batteries are made by a manufacturer I do not know much about, but their weight is an indicator that they are likely good quality. The 300W of energy (and peak of 500W) provides enough power for a small amount of electronics and small appliances, such as a laptop, television, mini fridge, medical device (like CPAP), and car freezers, but will NOT work for most rice cookers, and definitely not for a vacuum, water boiler, or circular saw. Like the bigger E1000, the hard, plastic material used to help shed weight (and cost) could be prone to cracking from hard falls or bumps, potentially exposing the Lithium-Ion batteries to puncturing. The fixed carry handle unfortunately cannot be folded, making it not ideal for packing things on top. Functionally, this is an excellent, portable power station with a multitude of AC and DC outputs, is solar charging capable with MPPT built in, and has a battery management system (BMS) to help ensure safety. Equally important is its verified claim of a pure sine wave - not modified - AC Inverter to produce clean electricity for sensitive electronics. Like Goal Zero Yeti 500x, Jackery finally upgraded the E300 with a USB-C PD with a 60W output. The E1000 only produces 18W. This makes it very useful for charging supported laptops. Jackery is one of Amazon's top sellers in the portable power station category with good customer service and reasonable prices, and as this is no longer my first experience with their products, I have no hesitation to recommend its latest product. PROS - At 293 Wh capacity, it is an improvement over its Explorer 240 model and falls in-between Goal Zero's Yeti 200x and 500x capacities -- Capacity to power a 30" LCD monitor and Mini PC for 3-5 hours, a Toshiba 50" Fire TV for almost 2.5 hours - Pure Sine Wave AC Inverter capable of continuous 300W power (and 500W peak) - More details later - Very well-priced at $349 at launch - Can power AC and DC (USB/12V Car adapter) at the same time (as long as they draw less than 300W combined) -- Laptop, tablet, phones, lights, fans, CPAP medical device, projector, TV, mini refrigerator, speaker, camera, DSLR battery charger, and SOME rice cookers - USB-C PD port outputs 60W - Can be used while charging - Faster charging with MPPT controller (Maximum Power Point Tracking) - Informative LCD with LED backlight -- Total power coming in (via solar panel or AC adapter) -- Capacity left (as a percentage) -- Total power (AC and DC combined) being used --- Suaoki G500 displays the Wattage separately for DC and AC, which I prefer -- Unfortunately, estimated hours to full charge or empty is NOT shown - BMS provides built-in overload, overcharge (automatically stops charging when the device is full), and short-circuit protection -- Multiple fans to keep the station's temperature safe - VERY compact at 9.1" x 5.2" x 7.8", though the higher-capacity, slightly larger Goal Zero Yeti 500x is still my favorite for its size and capacity - Portable at just 7.1 lbs - Bottom is well-protected by bright-orange, non-slip feet - Carry pouch included to hold AC charger and cables - Cigarette socket cable included - Unexpectedly good customer service -- Technical support was excellent in answering all my questions - 2 year warranty - Clear, well-written manual, though details were scarce -- Goal Zero's manual, on the other hand, is VERY detailed and helpful - Company is based in California CONS The E300 shares almost all the same design problems I disliked about the E1000, but also adds some improvements. - Batteries are not made by a globally well-known, Tier 1 manufacturer -- My unit came with fuel cells by EVE Battery, a China-based, publicly-traded company - No Anderson input port for solar charging -- You charge with an (optional) Anderson-to-8mm converter cable instead - Fixed carry handle cannot be stowed away -- Makes it difficult to stow things on top at the back of a trunk -- Upward-curved top (underneath the carry handle) does not allow small items to be temporarily stored on top - Hard, plastic material makes the power station lighter, but could be prone to cracking from hard falls or bumps -- Given that Lithium-Ion batteries become more volatile as capacity increases, one should handle the product with care - Although the exterior looks very professional, once I saw the Goal Zero Yeti 500x, I fell in love with the Yeti's design - Power buttons can be accidentally turned on/off through a single press (ie. while packing away your camping gear) -- Can lead to accidentally turning on/off the output during transport -- May unexpectedly find battery fully drained when you need it -- Suaoki requires you to hold the DC or AC button for 2 seconds before it turns on/off that output, helping to minimize accidental presses -- No automatic power off once no power is drawn/station has become idle - AC power brick is flat and large - No built-in flashlight or SOS signaling that the E1000 includes - Display is not as informative as I'd like -- Only shows battery charge level, input and output wattage, but no estimate of time remaining to full charge or to empty - Multiple fans turn on during high peak and can be too noisy for some - Battery cannot be replaced. This can lead to unnecessary landfill waste - Cannot be daisy-chained to other Explorer 300/1000's to extend battery capacity -- Some Goal Zero stations can be hooked up to other ones so power can be provided for an even longer time without needing to switch - Not waterproof. Keep it away from water splashes, rain, and pool! -- Lithium and fire or water can cause serious damage or injury! - No master power off button to turn off ALL outputs at the same time -- You have to manually switch off each type: DC, AC - No carry bag for the power station itself is included -- BUILT Willis 11" Insulated Lunch Box (ASIN: B08D6VMGG1) fits the E300 perfectly well (with usable pockets) when the Jackery is put on its side INPUT PORTS - 1x 8mm -- Accepts up to 90W -- Max 12-30V and 8A with no minimum wattage --- WARNING: Do NOT use a power source/solar panel that exceeds 30V or 8A! ---- Be mindful that solar panels that are daisy chained in sequence/series may output more than 30V combined! -- Can be used for solar charging --- MPPT charge controller is built in --- I recommend using a panel that's between 30W – 100W at 18V (with the right Amps to equal 100W) ---- If you attach a 120W solar panel (with 12V x 10A = 120W), it will charge at only 90W --- I did not test solar charging as California is currently blanketed by smoke from the massive fires all over the west coast --- Jackery SolarSaga 100W charged the Explorer 1000 at an excellent 69-88W of input. I expect it to be similar with the E300 OUTPUT PORTS - 2x AC with 3 prongs (120V) -- Inverter can handle a continuous 300W, peaking at 500W. More on that later -- Pure Sine Wave Inverter --- Ensures clean power to protect against damage to sensitive electronics --- Generates less heat --- Note: Some manufacturers claim to be Pure-Sine when they are actually Modified or Square Waves - 1x Cigarette socket (12V, max 10A) - 1x USB-C PD (5-20V, max 3A, max PD 60W) -- PD (Power Delivery) allows a device to be charged with up to 60W through the USB-C interface - 2x USB-A (5V, max 2.4A, max 12W) -- One of them is a QuickCharge 3.0 for rapid charging of compatible devices USAGE - To turn ON or OFF the Car/USB (DC) or AC outputs, press the corresponding button -- Note: This single-press (without hold) can lead to accidentally turning on or off the power station - To reset an Error condition that's shown on the LCD (ie. AC port is Overloaded), turn OFF the respective AC or DC output, and back on - To reset the Explorer, hold the DISPLAY button for 10 seconds - Li-ion batteries have 500 charge cycles before capacity drops to about 80% from when they were new -- Product could, in theory, be charged up to 2,000 cycles — about 1/4 of total capacity is lost every 500 cycle - Unlike LiFePO4 batteries, Li-ion can operate only in temperatures between 32-104F (0-40C) -- Jackery's Battery Management System (BMS) prevents: --- Recharging in temps outside of 32 - 95F (0 - 35C) --- Outputting power in temps outside of 14 - 104F (-10 - 40C) - Battery, like all Li-ion, slowly drains over time even when station is powered off -- Could take 1-1.5 years to go from full to empty CONTINUOUS VS PEAK OUTPUT The Explorer's AC Inverter provides a continuous output of 300W with a peak/surge of 500W - AC Inverter: Component responsible for converting battery (DC) power into AC for use by electronics - Continuous Output: As long as a device (or combination of multiple ones) does not exceed 300W, it can be used -- Example: A TV that uses 100W can be used because it is less than 300W. You can add more devices as long as they do not exceed 300W combined -- Example: A miter saw I have uses 1,800W, and because it exceeds 300W, it cannot be used - Peak/Surge: Almost every device temporarily draws more power when it is turned on. The highest amount it pulls during that time is the Peak/Surge. This Explorer can accept up to 500W -- Example: A TV that uses 200W (continuous) may temporarily suck up 400W (peak) when powered on. Because 400W is less than 500W (peak), this battery will allow the TV to turn on at that level for a few seconds (any longer, and it might cut power as a safety precaution). After a few seconds, the TV then only uses 200W (less than the continuous 300W limit) until the battery is drained -- Example: An unusual device that uses 250W (continuous) and surges to 1,500W when powered on would instantly be shut off by the Jackery. Why? Even though the device uses just 250W while already on, it jumps to 1,500W when powered on, exceeding the 500W surge limit of the Jackery CALCULATIONS The below calculations are rough estimates as conditions, quality, and product age can vary. CHARGING TIMES - Wall charger: 4-5 hours -- AC adapter was observed to provide 76W when charging level was at 37% -- AC adapter will gradually charge slower as battery reaches full capacity (for safety reasons) - 100W solar panel: depending on weather conditions, it should take about 5-6 hours. I could not fully test this because the smoke from the California fires is blocking the sun -- WARNING: do NOT connect panels sequentially or you may output too much voltage and fry the power station! Connect them in PARALLEL with a Y-Branch cable - Goal Zero Yeti 500x can combine its 8mm and USB-C PD ports for a total input of 180W. Neither the E300 nor E1000 can combine both inputs HOW MANY WATTS DOES A DEVICE US? - Calc: Watts used by device = Voltage x Amperage - If a vacuum is 120V and 9.5A, it uses 1,140W If a device draws more than 300W for an extended period of time, the power station will shut off as a safety precaution. This can also shorten the battery's lifetime HOW LONG CAN A DEVICE BE USED FOR? - Calc: Hours available for device = Battery capacity (Wh) x 0.85 / Watts used by device -- Generally, about 10-15% of power is lost during power conversion - If a device uses 60W, it could last up to 4.1 hours (293 Wh x 0.85 / 60W) - Amazon TV I have uses about 100W -- If battery is full at 293 Wh, TV could run about 2.6 hours (293 x 0.9 / 100) HOW LONG DOES IT TAKE TO CHARGE A DEVICE? - Calc: Hours to charge device = Device's battery capacity (Wh) / Input Wattage - If a laptop accepts 60W of input and its battery capacity is 200 Wh, it could take 3.3 hrs to charge (200 Wh / 60W) HOW LONG DOES IT TAKE TO CHARGE THE EXPLORER 300 WITH SOLAR? - Calc: Hours to charge battery = Battery capacity (Wh) / (Panel Wattage x [0.5 or 0.75]) -- In a perfect lab environment, solar panels charge at the indicated wattage (ie. 150W) -- Expect to only receive 50-75% on a good, sunny day (ie. 75W - 113W), depending on environmental conditions, panel's age, and component quality -- Tip: Even if it is overcast, the panels will STILL collect solar energy. Keep charging! - If a solar panel is rated for 100W, it could take as fast as 3.9 hours [293 Wh / (100W x 0.75)] to charge HOW DOES ITS CAPACITY COMPARE TO POWER BANKS? - Calc: Powerbank-equivalent capacity (mAh) = Battery capacity (Wh) / Voltage x 1000 -- 1 Ah = 1000 mAh - Explorer's 293Wh at 3.6V is roughly a 81,389 mAh powerbank (293 Wh / 3.6V x 1000) or a 27,129 mAh at 10.8V TIPS - Always test your devices with the power station before you depend on it on the go - Lithium-ion batteries are volatile -- To minimize fire damage to your belongings or loved ones, store the power station in the garage and not inside the house. Best storage is a dry, cool place, however -- You cannot bring a battery of this capacity on a plane - With the right BMS, quality batteries, and other factors, the power station can be stored in the car while camping during a hot, California summer -- Keep the battery out of direct sunlight. I usually store it on the floor of the car and crack open the windows a tiny bit -- Do not USE in the car if temperatures fall below or exceed the battery's rated, operating temperature (32-104F or 0-40C) Keep your car cigarette lighter with the power station -- you could plug it into its 12V DC socket for starting a camp fire - If using a car charger, make SURE you only charge this station while the car is RUNNING. Otherwise, you'll deplete your car's battery and leave you stranded - If charging with a solar panel, be sure to keep the station out of direct sunlight as it could overheat -- A solar panel is NOT required to use the battery -- Explorer 300 uses the MPPT solar charge controller --- Smarter, more efficient/expensive than PWM --- Suitable for larger systems - Can be used and charged at the same time. Manufacturers’ recommendations for their own products: -- Yes, that’s fine: Goal Zero, Jackery, Rockpals, nrgGo -- No/Not advisable: Suaoki - NEVER charge the power station itself in below freezing temperatures, or you will damage the Li-ion battery AND potentially limit its overall capacity -- You CAN use it to power OTHER devices because the generated heat will warm its battery enough to be within operating temps -- At below freezing temps, keep it in an insulated cooler and connected to a power source (ie. solar panels). The heat generated by the battery will keep it running as best as it can - Turn off any output ports (AC/DC) that are not being used in order to conserve power - Do not use any power station in a tightly enclosed area as it can overheat - To prolong the battery lifetime while in storage, keep the battery fully charged every 3-6 months -- Or, according to customer support, keep it plugged in when not in use and discharge it to 50% every 3-4 months -- NOT using the battery for a very long time can actually hurt its lifetime -- There is no "memory effect" in this station's battery. It is better to NOT let it completely drain FINAL THOUGHTS The Explorer 300 is another winner for Jackery in that it has made several improvements over its older, bigger brother, the Explorer 1000. I was disappointed to find out that its batteries are made by EVE Battery, a Chinese, publicly-traded company I have little knowledge of. The Explorer 1000, on the other hand, used either LG or China-based BAK Battery, both of which are excellent manufacturers. The company has shown time and time again that it takes customer service VERY seriously, and to me, that is a major plus. The 300W of energy (and peak of 500W) provides enough power for a small amount of electronics and small appliances, and is the perfect size for my little boy, the fellow explorer and camper. The hard, plastic material commonly used by power stations to help shed weight and cost (just like the E1000) could be prone to cracking from hard falls or bumps, and as such, this product should be handled with care - a puncture of the Lithium-Ion batteries could cause severe harm. The fixed carry handle unfortunately cannot be folded, making it more difficult to pack things on top. Jackery is one of Amazon's top sellers in the portable power station category with good customer service and reasonable prices, and if the new EVE Battery manufacturer proves to be as reliable as other Tier 1 makers, I will have no hesitation to recommend its latest product.

Living in Florida, I’m no stranger to power outages when storms roll through — I’m always scrambling at the last minute hoping the electricity will hold. That’s part of why I bought the Explorer 300… and also because I love being outdoors and going on camping trips or spontaneous weekend getaways. ⚡ Backup Power When It Matters When a storm hits or the power goes out unexpectedly, the Explorer 300 gives me a quick, easy backup so I’m not left completely in the dark. I can charge phones, laptops, a few lights or fans — enough to get through a blackout without stressing. Because it’s clean and quiet (no gas, no fumes), it’s much more convenient than a traditional generator when I’m stuck at home. 🏕️ Great for Camping & Outdoor Trips When I’m headed out on camping or a weekend trip, this little power station is a game-changer. It’s light enough to throw in the car or a bag and carry easily. I can charge my phone, run a small fan, power a laptop, or light up a tent at night. It feels like having a portable, travel-friendly power source that doesn’t weigh me down — perfect for someone like me who loves getting outside. GearLab +2 Tool Reviews Ninja +2 ✅ What I Love The portability — it’s so light and compact that I don’t stress about it being bulky. GearLab +1 It handles small electronics really well (phones, laptops, LED lights, small fans, etc.). GearLab +1 Having a backup ready when hurricanes hit — gives peace of mind. Being able to unplug and bring it camping — no worry about plugging into a wall or dealing with noisy generators. ⚠️ What to Know It’s not built to run heavy-duty appliances — so don’t expect it to run a full house’s A/C or a fridge for days. But for essentials and small devices — at home or on the road — it does a surprisingly good job. GearLab +1 💡 Final Thoughts: For Florida Homes and Outdoor Lovers If you live somewhere with unpredictable storms and you love getting outside — like me — the Explorer 300 isn’t just a “just-in-case” backup. It’s a reliable, useful tool for both everyday emergencies and fun adventures. I’m really glad I have it. Last but not least: great value for the money!

Every thing is ok. It is doable for one night camping but it is not enough for two nights camping if use an electric refrigerator. Also, it shown the available hours when you charging but it is weird that different wattage has the same hours. It is worth of the value, and recommend to have it if you like camping.

It has been an excellent investment. It is compact, light and very easy to transport, which makes it perfect for trips, camps or to have as a backup in case of a blackout.

I was able to power my LED patio lights and custom neon sign for 5 hours at my booth, which is perfect for local night markets when you don’t have immediate access to power! It charges very fast, quiet, and lightweight! Love all the different charging ports for all my charging needs. I would highly recommend getting one! I was a nonbeliever for so long, but now I get the hype of Jackery!

Muy practico , pequeńo , liviano útil . Ahora si a sacarle provecho.

The Jackery Explorer 300 is the sweet spot for portable power! It’s lightweight, compact, and super easy to throw into the car for camping, fishing trips, or road trips. It handles charging phones, laptops, drone batteries, and running small electronics effortlessly. Paired with a solar panel, it recharges quickly and gives complete peace of mind off-grid. Highly recommend!

I bought this specifically for powering my CPAP unit when on camping trips. Previously, I had been bringing along a 12 V deep cycle marine battery for 2 to 3 day trips and this is more than enough for a weeks worth of nights using the CPAP, but it’s bulky and heavy. When I camp, I use a Phillips dream station CPAP with a pressure setting of 7.0 and I remove the humidifier from the unit, and I do not have a heated hose, so the only draw is from the blower motor itself. This is where the new Jackery E300 comes into play. I have a DC power adaptor for my CPAP unit, so I plug it into the DC input on the Jackery. I tried it inside the house, kind of as a control sample, to see how many nights I could get off of a full charge. I was very pleased with the results. I ended up getting 4 full nights totalling 35 hours of CPAP run time. There was 2% left after night 4. I’m going on a 2 night trip next weekend, so I am quite confident that I will be able to power my CPAP with this unit in the outdoors even if the temperature gets down to around zero at night. I will update this review after my trip, but so far, I am very pleased with this purchase - and it only weighs 7 pounds. UPDATE: I just came back from the two night camping trip and I used my Jackery to power my CPAP in the woods. I started off with 100% charge, and after two nights I was only down to 71%. I even used it to charge my phone and bluetooth speaker on the second night. It was -3 both nights, so I was getting very similar numbers outside in that cold compared to inside my warm house. I am satisfied with this purchase. I look forward to many more nights of using this unit.

This little Jackery Portable Power Station Explorer 300 what is a real game changer for me. I am a 76 year old paraplegic lady, living in an assisted living facility in a small town in Ontario. Sometimes the winter time, we lose our power in the whole building for up to four days. It can be really annoying if your batteries on your phone or iPad, etc., get too low, you’re out of luck. I can’t use my kettle, turn on the light or even charge my power wheelchair. Today, I received my little Jackery, and WOW am I impressed. I ordered it yesterday afternoon, and it arrived less than 24 hours later, on time and with a very pleasant Amazon driver. It was packaged very well, and when I took it out of the box, I noticed it even comes with a little pouch with the enclosed wall charger or cigarette lighter charger, and a little information booklet. I was worried that I would not know how to use it, as I am not very techy. However, it was very straightforward. Basically plug-in and go. It arrived at 46% charge level. I immediately plugged my iPad into it. My iPad was at 55% and the Jackery ran at 9 to 15%W output. It took just over an hour to bring it up from 55% to 100% and the Jackery only went down by 3%. I can see where this will really come in handy during those freezing cold winter months we get here in Ontario. I will be able to run a light or two, charge my phone and iPad, boil a kettle for a cup of tea or hot water to wash myself with. Who knows, I may even be able to run the heater in here. I’m not sure what wattage it is. I will have to check before I try using it on my Jackery. It was a great price, andvwas on sale, so I snatched it up immediately. I’ve seen so much online about these little Jackery’s and decided it was high time I got one for myself. Best purchase I have made in a long time! Bring on the cold winters, my bad boy has got this! I wouldn’t hesitate to recommend this Jackery Portable Power Station Explorer 300 to anyone. I promise, you will not be disappointed! 😀 👍🏻

This is a must buy if your camping or doing big roadtrips or even fishing trips! I love mine an has probably over 300 cycles and still running strong!
