BALDR Portable Power Station, 330W(660W Peak) Solar Generator, 288Wh Solar Power Bank 120V Pure Sine Wave AC Outlet, 78000mAh Backup Lithium Battery for Home CPAP Camping Travel Outdoors Emergency

This is the second time I had to update my review in just a few weeks. I keep discovering the things I originally complained about were my own fault. I changed the rating to 5 stars because all the features work as advertised and it's a nice package for the price. I'll go ahead and mention I'm pretty new to solar 'generators' and my first one was a Jackery 240 which spoiled me a little and some of my misunderstanding of the Baldr 330 is because I assumed it would behave similarly, but there is an important difference. Like the Jackery, the Baldr has little buttons to turn on which plugs you want to use (12v, USBs, AC), but unlike the Jackery the Baldr has a master power button that is clearly marked as such. It took me a while to catch on to how important it is to always turn off the main power if not in use. I thought the battery was consistently losing its charge to the tune of about 6% each day when unused -- and more importantly I thought it was turned off because I knew I'd hit the power button -- but turns out plugging in the solar panel to top it off turns it on again. So each day of non-use, I was begrudgingly topping off what it lost from the previous day and returning it to storage only to find the same problem the next day. Even if you just turned the power button off a second ago, and wait several seconds for an audible beep, if you plug it into a power source it comes right back on. I thought it was just the display waking up, like the Jackery, but it's the main power. Now that I'm constantly aware of this, it's holding its charge perfectly. If I store it at 100% and make sure it's completely off, it stays at 100% until I need it! Another thing I'd complained about was the USB-C port seemed to stop working and this was one of the main selling points for me over its Jackery equivalent... but again, there was no fault with the unit, only with my understanding. I was trying to charge my macbook which I read somewhere it can't do, but my laptop at rest tends to pull 16w which this USB-C port is rated for, if I understood correctly. When in use, my laptop pulls 45w but I wasn't trying to use it on the Baldr, just recharge it at rest. The thing that really threw me off is that it worked a few times at first! The laptop made the "charging" sound when I plugged it into the USB-C. But after a couple of initial successes, it no longer showed any signs of being plugged in and the Baldr screen showed no outgoing power. Using the AC adapter/port worked fine, but I really didn't want that clunky adapter occupying the only AC plug on the unit. So I found a work around. I'm now using high-capacity portable battery packs that I plug into the USB plugs on the Baldr while the Baldr is charging on the solar panel. In theory my solar panel has USB ports and should be able to charge the portable battery packs directly but it seems to take longer that way; I'm not sure why. So I let the Baldr charge the extra battery packs while it's recharging on solar. Seems to work fine; I can get everything topped off again on a good sunny day. A third thing I'd complained about was the wireless charging didn't seem to work unless it's directly connected to power, but I discovered it's the case on my phone causing that problem. It seems the case is causing just enough resistance that it doesn't get the power unless there's an incoming stream. I finally noticed this because I my regular wall charger (plugged into a wall outlet) that acts up sometimes and I have to move the phone around to just the right position for it to pick up power. It dawned on me it wasn't both chargers having problems, it's my phone case. With all that cleared up, here are my original pros and cons lists, but with the cons corrected. What I like about this unit: + size and weight are better than expected. It has a sturdy feel without being heavy or bulky. The handle has a rubber grip on it which makes it extremely comfortable to carry. + charges easily from my solar panel; speed of charge varies depending on weather, obviously, but the recharge time seems about the same as my Jackery 240. (I haven't actually measured, though.) + display screen is good. It shows the battery percentage, the incoming power, and outgoing load. There's nothing more I would ask for on the display. + USB-C port is handy; it eliminates need for extra adapters + the light bar has come in far handier than I expected. I use it more than I thought I would. What disappoints: - fan kicks on more often than I expected (i.e. more often than my Jackery 240). It startled me the first few times because I thought it was overheating, but now I've just accepted the fan runs a lot. - the display screen doesn't go to sleep; it just stays on until you turn off the main power button. Sometimes the first click isn't enough and I have to try again. It makes an audible beep several seconds after turning it off... I'm not sure why the delay. - charging the unit turns the display screen back on whether you want it or not, and because it doesn't go to sleep, it will keep draining some of the power until you manually turn it off again. Conclusion: Baldr 330 has a great set of features for its price and performs mostly as expected. I wish the display screen functioned better, but I have no regrets about the purchase and might consider buying another in the future. It's probably a great entry point for getting into solar/off-grid power.

Now I can go on nitpicking about the no screen control, the charger not even being 100w, and whatever other little insignificant issues I had with it, but ultimately it's a good purchase. Easy to carry around and not that easily damaged or scraped or anything, works okay at sub 300w which is what I expected (might get hot tho so definitely best in a cool place or left too cool down without charge or use afterwards). I'm using it with my Rog Ally and it gives me like a good 6 hours of full charge while I'm using a monitor powered on the dock as well, heck I even run my gaming PC on this thing for like 3 hours on older or less demanding titles. Good purchase, don't expect to be running anything but a budget gaming PC or a laptop on this thing tho lol (and ofc phones and tablets are the best things for stuff like this).

UPDATE: 11/26/2025: It’s been a little over 5 years of using this power station & I’m BEYOND impressed! For the past year, I’ve been using this to charge my Dewalt batteries, power a car vacuum, running high wattage UV lights to cure UV resin, running led lights and a lot more. This is all in my off-grid shed. I’m actually debating on buying another one, so that when the original power station runs down, I can charge it with the Baldr Solar panel, and then run everything of the back up! This most definitely was a GREAT purchase and now 5 years later a new upgraded model is ONLY $100.00!!! I paid $300 for mine and now they’re a hundred bucks! Will it run a refrigerator, no not a chance. But you can do quite a bit with it. Original Review: I bought this along with a knockoff DC power adapter for my ResMed Airsense 10 cpap machine. When I received it, the unit had 50% charge. So I plugged it in and charged it up to 100%. I was about a week away from my vacation/road-trip and tested it out to make sure it worked. Almost all the reviews state that with heat and humidity set to zero, you could get 4-5 nights of use, from the Baldr 330 power station. Since I have sensitive sinuses, I have to use humidity otherwise I’d wake up with a seriously dried out nasal cavity. I also used heat along with that. I think the heat was at 70 degrees F and humidity was at level 2. Starting from 100% charge that night, after 7 hours of sleep, the Baldr dropped down to 75%! During my road trip, I used it that way for the first 3 nights (with heat and humidity) and the battery dropped down to 40% & I also charged my iPhone at night. During the daytime while driving, I charged the Baldr 330 with the provided DC power cord that came with the power station (there’s also an 110AC & solar adapter, for charging) and the battery went up to 80%. This didn’t worry me, because I knew I’d get 2-3 nights off if that charge. After having work flawlessly during the 7 day adventure, the only criticism I have of it is that the DC power adapter cord is pretty short and I had to pick up a 12V extension so that it could charge while sitting on the passenger seat of my Outback. On top of working flawlessly, it as built in QI wireless charging, an LED light and a convenient fold away carrying handle. This thing is probably the BEST PURCHASE I’ve ever made. Make sure you get a DC POWER ADAPTER for your cpap and use the 12V outlet, if you use the AC outlet, it WILL run down faster.

This is going to be about the third time I have updated this review. First it was 5 stars, then I dropped it to 3 when I ran into some shortcomings, now I am going back to 4 after having great discussion with their customer service about what the product can and can't do. I am very happy with the durability and fit/finish of this device, and its amazingly light despite how much energy it can store. This has become the main power for our tent, we run two LED bulbs off the DC barrel jacks and our automatic air mattress with the AC inverter. Our air mattress is dual pump and the secondary pump works silently to keep the air mattress topped off so long as it is plugged into AC power. This power station has worked great for that, and then to top it off we can charge phones and all our other small devices as well like our GoPros and little bluetooth speakers, we have USB-rechargeable walkie talkies, etc. This unit stores enough energy to get us through most any camping weekend and we still tend to have 40-50% charge left by the time we leave on Sunday. I was a little bummed that I could not use AC inverter and recharge the pack via solar at the same time but this was clearly labeled up front. I was also disappointed when I found the 10 amp DC output could not support our 12v refrigerated cooler. Our cooler only draws 50 running watts but the startup spike is too high which causes a voltage sag and triggers under-voltage protection. After discussing this with their support this is not unreasonable for what this product is, just a tad disappointing. We still find many other uses for it and appreciate having the backup power at home as well, but the search continues for a solution to running our 12v fridge off of something besides the car battery. The AC inverter works with an adapter but the cooler uses more energy than I realized and I run out of power mid-weekend if I use it that way. No fault of this product just my lack of understanding and poor guestimation of my needs when I bought it. The wireless charging is a neat touch that just now other competitors are starting to add to theirs, we like that. The built in light is also handy for getting setup in the tent (our tent has dark rest coating that blocks most sunlight). I like the display that shows how many watts things are drawing, helps me estimate how long it will last. I should have bought a bigger pack for my particular needs but this one is still useful and would recommend to anyone with less overall power needs this is fantastic for camping and backup power. I still withhold one star just because of the DC output giving me some issues with anything that has a startup spike and the AC inverter not being able to run while recharging from solar, lack of beeps to indicate when overload protection has been tripped, no watts measurement for the USB ports, battery % doesn't drop very linearly, just a couple minor things like that but really more like 4.5 stars if I could.

Ok, I want to start by saying: this is my first power bank... That being said, Baldr has set the bar real high with this product. It has multiple USB charging ports, an AC outlet, 12v DC outlet, a backlit usage monitor, DC car charger, solar cables/connectors, various connector types, a handle and even a built in flash light (an awesome addition, by the way). It's small, light, and when the fan kicks on it's quiet... After receiving the item and charging it to full capacity, I wanted to put the device through some practical tests, so I charged a few small devices: cell phone, portable DVD player, computer, etc. The results were that, those devices didn't put a dent in this bank, whatsoever. So, I upped the draw and hooked up my PS4... With only the PS4 plugged into the bank, I was able to game for an hour and a half, uninterrupted, bringing the remaining power to 50%. That's impressive, to say the least. As you can see from the photos, my vehicle just got a recent travel upgrade and I'm going to be bringing this little fella' everywhere I go. I don't plan on playing much PS4 out of my car, but I thought it was a cool way to show the types of impractical applications that become increasingly practical with an amazing product like this. I DO plan on using this bank to power my XP Pen Drawing Tablet, so I can paint some scenery on location. How crazy is that? Sitting in the wilderness with a 22in digital canvas is something I never expected to do, but that's the plan. I recommend this powerbank to anyone remotely considering (pun intended) living off the grid. I'm also looking to pair this thing up with a 100w solar panel to make it truly off grid. Or, if you just want to DIY - Pimp MY Ride, then this is your jam right here. Jam on!

This little guy is lightweight and has power to spare. In a pinch I can run my refrigerator for an hour each day and have power to spare for my laptop, fan, and TV. The only thing I don't like about it is the charge rate of 52 watts. If I had known that in advance I would not have purchased the 120W solar cell. Once charged you can keep it on the shelf for emergencies and then turn on the power for USB, 12V accessories, or 120 Volt pure sine wave AC that can run just about any small appliance. I have an energystar refrigerator which doesn't require much of a surge to start so it plugs in and works perfectly -- I get a full hour out of it with the solar panel plugged in. Under a typical day I can keep my produce cold (in case of extended power outage) plus have enough left over to run a small (32" tv), fan, and laptop for 4-5 hours. The larger solar cell they have also has a USB port so that extra energy can be used to charge phones or a standby battery. Use it for camping, going to the beach, or for emergencies -- I'd buy another -- especially if they sell a slightly more powerful unit that can charge more than 52watts at a time.

I've tried all the connections, everything seems to work. I used this 6 or 7 times never drew it down below 51% before recharging till this test of the A/C outlet using a Kill A Watt P3. Pulled it down till it shut itself down (at 4%) and immediately recharged. The pictures are the results of the time to discharge and recharge that I came up with. I don't think I would draw the unit below 20% as I've read discharges below that are harder on the life of lithium batteries. I got the Togo 120 watt portable solar panel too and it charges this quite well. In full sun seems to always be at the max input of 52 watts. I haven't had it long so I can't attest to longevity of the unit. I do wish they made these with replaceable batteries and or some way to use my 6AH 40volt SunJoe batteries (have several would be neat if a guy could just plug them into a unit). One of the pictures is a spreadsheet I made up in an old version of MSworks, I adjusted the .85 that seems to be the norm for converter efficiency to .81 to more closely match my test results though the difference may be in that it shuts down at 4% (good feature to protect the batteries). Adding to review. 2/1/22: In February of 2021 my wood shop burned down. I didn't have any electric to work on rebuilding it for a while. I used the Baldr unit for several things. I ran a 1/4 hp sump pump to drain the pond after it would get filled with rain. The initial start up of the pump tripped the unit off a couple times until it got enough water into the hose to start a siphon action then it ran continually to drain the pond. I also used it on a 4.3 amp die grinder to grind out a nail on a post before drilling it out for a rebar pin. Though at 4.3 amps that should have been over 500 watts, the unit ran fine and said it was only drawing 310 watts. I also used it to run a float battery charger to keep my snowplow battery maintained since it has a parasitic draw and I usually had it plugged into an outlet but no power most of the summer. Worked really well for that ran the battery maintainer for several weeks before having to recharge the Baldr. It certainly came in handy for me. Everything on it still seems to be working fine, it's holding a 100% charge for at least 2 months ( while not using).

So we have been using our Baldr generator for around 3 years now. Works great, the light is pretty useful and it has been a lifesaver many times. Definitely worth the price and the size is perfect. Cons: After using it nearly daily for almost two years, it now only charges up to a certain point. However, it keeps that charge for a long time so its really not a big deal. If you are looking for something light to go on camping trips and such, this could get heavy over time. The light drains the battery faster than I prefer. Its better to use an alternate light source to keep the battery lasting longer. The little caps to cover the ports did bream off about a year into daily use. But honestly that's pretty good. Pros: This generator has served us faithfully and consistently for nearly three years. For the price it is a great deal and a life saver. Long lasting battery, decent flashlight, and all-around good backup for emergencies.
