Portable-Charger-Power-Bank - 2 Pack 15000mAh Dual USB Power Bank Output 5V3.1A Fast Charging Portable Charger Compatible with Smartphones and All USB Devices (Deep Black and White)

Smaller, lighter, pocketable. I can charge as I use it, but only good for less than 2 total recharges. Replenishing the device is fairly fast.

I don't have a lot to compare these to; but I bought this terrifically well priced two pack after having bought a single one earlier. Power went out for twelve hours overnight during a summer thunderstorm and I decided I need a strategy for such outages. I got some rechargeable lamps that I keep on chargers all the time, a couple of reading lamps that have USB charging and internal batteries, and decided it makes sense to have power for my phone and laptop as well as an internet connection if this happens again. So these have an impressively high stated capacity and should run my phone which has a hotspot and I can connect my tablet to it to have entertainment and connection.With three of them I expect them to last at least a day or two, keep my personal electronics running and worst case I could recharge these with my car. And they allow for fast charging for smaller devicesThey look good (not that it matters) and they are pretty compact, about the size of a cell phone; have versatile input and output. If there's any shortcoming it's that the only outputs are both USB A (while using C and Micro to charge up) so I picked up some USB A to USB C adapters to make sure I could use a variety of cords for them and I keep them constantly charged. Not critical since most of us will have some USB A to whatever cords around.Maybe I'll never have an outage that long again but shorter outages are quite common where I live when summer monsoons roll through. I now feel I have what I need to make these events tolerable -- light, and information and entertainment. A battery powered fan should round out the needs.And they were a lot cheaper than a Tesla power wall (which ultimately is the right solution to power outages...) which I considered very briefly.

This charger works great for my long days at the market when I use my phone to collect payments. For this reason I also like the sleek, slim design I can just toss it in my bag and not have to worry about another bulky item.It charges fine and gets me through the day but if I'm low I have to keep it plugged in and try not to use my phone.I charge it up overnight and the lights aren't overly bright so that's good. Good source of power on the go but I would definitely plug in to a real source when I got; both my device and the portable charger.All in all I like it but, but the description says it's a fast charger, unfortunately, my Note 20 says otherwise. Maybe it's the cord (the one that came with it)? I can't use the one that came with my phone because the USB-C port on the power bank doesn't give power so I'm not really sure what that's for, maybe just to hold the cord when now in use?If I can find one that is a super fast charger I may very well return these.

I would not have survived my first few weeks in DC without these!! I keep one in my purse and one in my backpack for work now. They hold their charge for forever, so I just charge it up and leave it in my bags and they’re ready to use when I need it! They’re not heavy and they have options to charge a few different phones. These things rock!!

fantastic batteries especially for charging phones/laptops. They last forever. I have an iPad that has a preverbal dying battery and if you attach on of these it last for days. I have purchased 8 of these batteries of the last few years and the older ones are still going strong and hold a decent charge compared to other batteries I have purchased. My only issue is that once they hit 100 percent they stop charging the devices and if the item is not being used but like the above mentioned IPad it won't charge again so you have to hit the button on the side to wake it back up at times. But for the price and the longevity of the battery this is nothing.

I’ve had for several months. Still working good.

Nice to have these, I have 4 due to the weather here. Better safe than sorry.

This portable charger does what it is supposed to do. I can charge my phone more than once. It takes a little while to charge but once it is full you can charge your phone multiple times. I just wish the was a read out for the remaining charge instead of lights but it works so I will love with that.
