charmast Fast Charging Power Bank 20000mAh With Built-in 4 Cables 6-Outputs

Amazing power bank !

This power bank is very powerful and chages all you usb devices extremely fast. The built in cables with different usb connectors makes it very handy. The only inconvenience is that it is a little heavy but given the power it carries, I still have it with me everydsy in my bag. FIVE STARS!

Nice build quality good and working perfectly all wear

It was really helpful.iPhone 14 Pro and Samsung S23 can be fully charged twice on a full charge.👍 worth to buy.

So far so good have solved all the problems with battery.

Good one but take time to charge to be honest

Might be not usual but after just one month now the charger keep showing a stable blinking 100% but doesn't charge any device. And I cannot find any instructions online on how to reset it ( if possible )

It worked well when we travelled

It's been more than I year and it still works perfectly.

Beware this product is faulty.Power bank stopped working after 2 months. Worked great for 6 weeks and then the USB C cord started to only work every now and again. It's totally stopped charging now and the "return window" has closed.I even wrote a 4 star freebie for this age a coke of weeks. I hope the seller sees this review and offers an exchange. If not, this is a complete rip off.I will update if I get satisfaction from the seller. Until then I would avoid this product. 100% rip off. Faulty product.

I ran some tests with this device using 3 cord options (USBC, lighting and micro) and the stats are below. All tests the battery nor the device got warm and the battery percentage is always displayed. The time taken to charge battery from 0 to 100 is as advertised about 6ish hours using the USBC port. The device itself is a little weighty but that is definitely insignificant to the pros. It charged all three devices consecutively and still had over half its battery left. The built in cord length is sufficient for my needs (about 12.5cm) however if you rely on a long cord or just prefer that then you have the option to plug another cord direct into the battery pack. I would definitely recommend and will also be buying another for hubby.Test 1: iPhone 14 pro at 50% (using built in lighting bolt cable)Time taken to get to 100% = 84 minsPercentage of power taken from battery pack = 10%Test 2: Ipad mini 5 at 0% (completely flat) + apple pen 2nd gen at 15% (using built in USBC cable)Time taken to get to 100% for Ipad and pen = 110 minsPercentage of power taken from battery pack = 33%Test 3: Kindle Oasis at 67% (using built in micro cable)Time taken to get to 100% = 55minsPercentage of power taken from battery pack = 3%After all three of the tests above the battery pack was at 54%

I love these and they are extremely cheap for what you get out of it, they are small enough to fit in your pocket and charge your phone multiple times if needed, they have usb a and usb and usb c, so it’s easy to plug in multiple devices to this and it charges your devices very quickly, only downside is it takes a long time to charge the actual battery pack, but I have a few of these and love the functionality, it’s great to have them laying around to be able to leave the house if your phone is low battery you have nothing to worry about
