Powerful, Convenient, and Charges Faster Than I Expected
I bought this power bank because I wanted a reliable charger I could carry with me during long days out, traveling, or when I’m not near an outlet. The large battery capacity and built-in USB-C cable really stood out to me because it means I don’t have to remember to bring extra charging cords. So far I’ve been really impressed with it. The built-in cable is one of my favorite features because it stays tucked into the body of the charger and is always there when I need it. I also like the digital display that shows the exact battery percentage—it’s much better than guessing with little indicator lights. What surprised me the most though is how fast it charges my phone. It powers it up noticeably faster than I expected, which has been really convenient when I just need a quick boost The only real downside is that it’s a little heavier than smaller power banks, but that’s pretty normal for something with a 20,000mAh capacity. It’s still easy to throw in a bag or carry around, but you’ll feel the weight if you keep it in your pocket for a long time. I also wouldn’t mind if the built-in cable were slightly longer. Overall, I think this is a great option for anyone who travels a lot, spends long days away from outlets, or just wants a dependable backup charger. If you want something with strong capacity, fast charging, and the convenience of a built-in cable, this one is definitely worth considering.

Convenient, reliable and a tad in the heavy side
My new favorite portable charger. The included and attached usb-c is handy, it charges very quickly, and there are two more ports. Charge the device through the same cord you charge your phone! Has two other charging ports. Color is ok rather boring but that’s fine by me. I can charge it overnight and it holds a charge well. I get 4-5 charges for my phone and iPad over a week span which seems good. If you travel a lot using a carry on I’d look for something else. For a 20000 MA charger it’s heavy - if I could have rated it 4.5 I would, but opted to keep 5 instead of 4 stars. I use this at the office and home - have another charger for traveling by plane.

Great Power Bak Charger
Love this power bank! It charges quickly! The display is easy to see and the size is great. I have another power bank that is larger and heavier so this is good. Its still too big to carry in a purse and a little heavy but great for use around the house and when you have a power outage. I used it on my cruise since you have limited outlets.

Worth every penny, just treat it with respect!
1 year of daily use later this battery still impresses me, despite it's age showing plainly. I've been meaning to make this review for a while now so here it is... This device came into my algo at the perfect time, on sale with all the power I needed and I took that deal quickly while thinking that I would regret buying another cheap no-name thing off amazon simply b/c of a sale price. With only a handful of good reviews at the time (but barely any low star or bad ones) how could I not anticipate another Amazon gamble going south...but I'll tell you I was SO wrong. It came to me pre charged a bit, but I filled it up first just be safe. Took a little while to charge and thought it would always be like that, but that was my first misread. It also said in the documentation that the capacity it's rated for is not what you'll get due to loss during conversion or something...not even true; Likely just an explanaition to ward off liabilty in case their QC missed a bad batch or something. I regularly got at least 3 full charges on my 5000mh phone (under proper conditions) with seemingly enough battery (20-30%) to get a 4th but I always re-charge before full discharge so I never found out. It can handle both input and output of 45W which is phenomenal, and quite useful. Enough so, that I've used it on many occasions for my laptop to extend my usage away from outlets. Have also been able to fully charge it in one sitting at the cafe. It's a super simple design with a single button, 3 ports, and a built in USB-C cable that only an idiot would try to double as a carrying strap. It's viable, reliable, and better quality than you'd expect. That said, it's not feature rich, it's not Extra durable (despite it's heavy weight), it's not real pretty. It just WORKS! It's 20,000mah of 45W Power for dirt cheap! 1 ear later and I'm still using it, but I have to claim 1 thing... A few months ago, the device started getting a little finnicky in it's charging. It accepts charge from my standrad 20W phone charger and my 65W laptop charger (Both A/C wall power) with no issues, however it does not accept charge from my laptop's USB port any longer. It also is hit and miss in it's discharge, which tells me the battery is likely not the issue as would be expected from most electronics these days, but it's probably something else. Sometimes it has zero issues discharging too with it's full 20K capacity, but 60% of the time it's being difficult. I can't properly test it to accurately diagnose the problem, but I suspect it's damage to the internal controller/chipset and it's likely my fault. I've accidentally dropped the unit more often than I'd like to admit, I've also had it almost exclusively in a vehicle down in FL where it's seen humidity and heat at the same time for several months. B/c of all that, I suspect it's finnicky discharge is my human error. With that much needed explanation out of the way, I'd happily recommend this unit! What I'd like to see in the furure however is the following... + Wrist strap loop holes for easy (non-damaging) carry + Color schemes/Design patterns (the tesselation pattern on the back is super cool but hard to see, a little color in the grooves or something might accentuate it) + Wirelss charging (Qi, MagSafe,PixelSnap) + Silicon case or harness w/corner bumpers

Fast Charging Power Bank (1 of the Best)
I really love this portable charger it charges my phone in super fast charge mode unlike most portable charger. I have an older Samsung Galaxy Note 20 ultra so I have to charge my phone multiple times per day & this gets the job done ✅ Fast 🙏. Only cons is the battery is pretty heavy / bulky so it's not something ideal to carry in your pocket & to recharge the power bank it takes a pretty long time. However, I also haven't noticed that it doesn't gets hot like other power banks & it's airplane safe. I definitely would recommend to others

A reliable beast for power backup.
This thing is a beast! A reliable beast! It is heavy, but it gets the job done. When it is fully charged I can get at least 5 iPhone charges and several earbud charges out of it. At least that much. Very likely more. It stays cool while charging my phone. I’ve never run it all the way down, but I’m continually impressed that I can plug my phone in when the charger reads something like 28% and it charges my phone all the way up with power to spare. The power bank takes about 3-4 hours to charge itself up using a fast charger. The attached cord is very durable and feels securely attached. I like the design for clipping it back into place. It feels secure and can be done without looking at it. My only concern is the weight, but that might be the price to pay for so much power. It is a great value for the price. I like knowing I have reliable charging capacity for travel or if we lose power.

Awesome Battery Bank!
This power bank is a total game-changer! The 45W fast charging is incredibly quick, and the massive 20000mAh capacity easily gets me through multiple days of heavy use. I absolutely love the built-in USB-C cable—it means one less thing to carry, and it doubles as a handy strap. Being able to charge three devices at once is just the icing on the cake. Highly recommend!

Worth buying again - but made to last
Excellent. Fastest I've seen at charging other devices. Charging the charger from below 10% takes a bit of time, but it is well worth it. I bought a spare and didn't need to use it this weekend. The one unit quickly recharged an iPad, an Android tablet, and a couple of phones over the weekend, and still shows 21%. The cable really is as good as described.

Perfecto para viajes y emergencias
Después de buscar y comparar varias opciones de power banks para el uso qué yo necesitaba, esta fue la perfecta por costo y lo que ofrece. Con mi Oneplus 11 es más que compatible para Fast Charge, así como para una Chromebook de trabajo, que en ambos casos utilizan el máximo que ofrece esta power bank: 45 watts. Ojo, con el Oneplus solo alcanza Fast Charge, ya qué la tecnología propietaria de OP qué sería SuperVOOC es de 85w a 100w, la cual es más de lo que puede ofrecer esta batería, aun así se recarga suficientemente rápido dichos dispositivos. Para recargarla si se toma su tiempo con un cargador qué le mande la suficiente energía posible y la pantalla led solo indica el nivel de carga actual, lo cual esta más que bien.
