Portable Charger 40000mah Power Bank, USB-C (22.5W) Fast Charging Battery Pack Portable Phone Charger for iPhone 15/14/13 Series, Android Samsung Galaxy, for Travel Camping

A lifesaver when I went on my trip to Japan. Got it on sale for $20 and was definitely worth the price. It charges my phone at a decent speed and has enough capacity and power to charge my phone completely maybe a good 4-5 times before I have to recharge the battery. It is a good size too albeit slightly weighty. I was carrying it in a small crossbody bag so I could feel the weight a bit more, but if you carry it in a backpack it shouldn’t be a problem. Overall though amazing quality especially for the price!

I’ve had this for several years and I’ve had no issues with it at all. Perfect life saver, it stays in my car a lot in very hot environments and it was able to take all of that. All kinds of things you can plug into the power bank such as USB C, USB. It takes a little to charge but lasts a long time and depending on how often you use it, it can last you months at a time off of one charge.

This thing is amazing!!! I let phone charge down to 0 percent and I charged this charger to 100%. I kept track how fast it would charge my phone and how many charges I could get out of a full charge. The other day, it charged my phone from completely dead to 31% in about 15 minutes. I am currently on my fourth full charge and the charging bank still has 46% battery life. So, I could possibly get 4-5 complete charges out of one full charge and fast!! I plan on buying 3x more of these things for the boat and RV. I HIGHLY RECOMMEND!!

This was definitely a 5-star purchase. I've owned it for almost a year and a half, and it's been to Disney World and other theme parks 20+ days. On a full charge, it will completely charge at least four iPhones. On our last day at Disney, my wife and I both boosted our phones (from 20-25% up to 70-75%), and our three girls did the same, and we returned home with around 50% of the charger still remaining. It also holds a charge for months if not in use.

My husband keeps this charged up and in his bag for work. It holds long charges and allows you to use any usb device. He likes that it’s an on the go power source for his long days.

The power bank charges quickly, and it maintains a full charge for several days. My family can charge multiple devices simultaneously, iphones and accessories, Android devices, laptops, tablets, and flashlights! We live in an area of strong storms and possible tornadoes so it's always close at hand. It is also great for travel, but it is a large powerful power supply so it's not the one I carry in my purse, but for brief cases, travel bags, back packs, it's my go to because it holds it's charge for such a long time. I highly recommend this power supply!

So, I'm an Amazon delivery driver, an at my DSP, we get our key bags with our phones an a tiny USB C battery bank that hangs off the bottom of the phone.Our phones from 100% won't even last half a day, hence the backup battery. But they are heavy enough to drop off the phone, so we've all had to use rubber bands or tape to keep them secured. Even then, from 20% phone battery, it will barely get to 47%-ish. Still not enough to get us through our shifts. Many of us have resorted to using our personal phones to finish the shift.I got this to finally solve the power problem. It arrived with about 68% charge, an I've not charged it since. I just topped off my tablet I keep with me at all times from 90% to 100% an the pack lost exactally 1%. Amazing.Initially I was worried that it would take DAYS to charge the pack, but I've invested in the highest amp wall brick an cable it can handle. From what I understand, it will take not even 3 hours.My last power bank from a few years ago, a 6,000mAh bank, took nearly a day an a half! This is so much larger, but tech in battery charging has gotten so much better in the last few years. Hell, I bought a Bluetti 60L backpack with a full power station that tucks into it for 700W of use. I'll never be out of power again between that with a 200W portable solar array that clips on the back of the backpack, an this 40kmAh power brick.I obviously do not intend to lug around 16lbs of power station on my back plus gear, but it's a great alternative to my Generac 6500W gas-hog an loud as S*#@! Now my mother has silent power for a day an a half with her on a 24/7 oxygen pump, the Generac when that dries out.This 40kmAh pack seems like a tank an is very efficient. As an RC driver/pilot, I'm very respectful of LiPo an LifePo batteries, so I expect it to last years. Maybe losing a few percent of life over time. I expect in 5 years to have a life expectancy of 70 to 80-ish percent. Still great.I don't mind the weight. You sacrifice weight for capacity, an I know this all too well. But if what you want is a plug in an forget battery bank for a week with nothing more than charging the occasional phone or tablet like I need, you could do worse. Just make sure you get the highest rated amp cable an wall wort for your needs.Haven't had it long, but in a week an a half, an charging my phone once from half dead, an my tablet from 90% to 100% to test, it's still at 66% from when it arrived. (Lost a % due to parasitic loss, of course).

Nice solid feel to the weight and texture. My current setup is two 10k mah... this being a 40k mah. I think the power is spot on. It's 4x a 10k mah for sure. Takes up less space than my two 10k's, weighs a bit more than the two combined.
