    Charges fast and its charge lasts forever! I can charge my phone from dying to full 3 or 4 times before it need a recharge. A little heavy but what can you do.

    Well worth it! Keeps my Oculus, headphones, cell phone charged. I can play my Oculus all night with this attached. Could be a little cheaper overall but as expected you are paying for the Energizer name & their reputation of great batteries… Definitely recommended if it’s on sale anytime to buy it

    This is a pretty decent power bank. It holds enough guice to fully charge my Note 20 Ultra five times or so. However, it's a heavy, ugly brick. Zero consideration was given to making this thing anything more than a utilitarian box. I could overlook that if the Iack of aesthetics was offset by some rugged construction. It isn't. My biggest issue is absolutely the shoddy construction. I dropped it once, and it fell maybe six inches and landed on carpet. That was enough to shift the inside in relation to the casing to the point that the button to show the charge indicator lights no longer functions, and I have to use the connector on whatever cable I'm plugging into it to shift it in the casing ever to get it to line up enough to actually plug in. It still works, but it's inconvenient and I would have expected better construction. given the price, the fact that it weighs like five pounds, and is butt ugly. Overall, it does what it's designed to do, but isn't particularly rugged. Given a do it over, I would probably spend appx. the same amount of money on a Samsung power bank. They aren't as high capacity, but they're sturdier, have Qi charging, and are more aesthetically pleasing.

    Does work well for my Pixel phone. Would have been nice if it came with a carry bag and a led percentage display instead of the 4 dots, but those are very minor things. My pixel wouldn't fast charge with the usb-a to usb-c cable that came included but I have plenty of cords to use that worked fine.

    Battery works with all gadget as long it has USB port and last very long. Charging time takes about 5-6hrs for fully charge and the battery itself is heavy for carry on. It's good for camping or outdoors but won't advice to carry while at work or school because of its weight. It always good to have something to rely when power outage happen and this comes handy then. There you have it...Cebu.

    Nice add on. How do I use it? I hook it to the external USB port on my backpack. Most use that for a player or something but now I can get several device charges from my backpack.

    It is a battery and it works, so I'm keeping it. My wife took it on a trip and couldn't figure out how to charge it. Poor instructions and an included 6 inch "C" usb that is garbage. I threw out the included cable immediately. It has 2 charging inputs... one for a "C" usb cable on the side edge and another for a "B" usb on the bottom. Neither input is labeled... you just have to find them. Attempted to charge with 2 different "B " cables without much success... I got only 5% charge added in 5 hours... so gave up on that. The "C" port on the side worked much better... added about 30% charge in an hour. When using the included cable on my samsung S21 got the message on my phone that topping off my charge would take 3 hours and I should consider a different cable. Charging went to 41 minutes when i switched out to a better cable.
