This is the third power bank of that size and specs that I buy. Shopper+ was running this heavy discount on it and I bought a third one. All three of them supply good 1A/5V power, and have decent capacity. I've been using it with a Sony RX100m4 camera as an external power source, and it works well. The built-in flashlight can be useful in a pinch but it's not very bright. I could see it used in camping for a long-lasting, low-power night light. Recommended if you are looking for a small powerbank. Only caveat is that it does not support fast charging or anything fancier than 5V/1A output, meaning it's slow charging for some devices.

I purchased this item on a Black Friday sale - so the price was especially low. With this in mind, it is a killer battery pack, I use it on a gimbal to power my RX100 camera so I don't have to deal with battery life. Great also for a GoPro Hero 4, lasts a whole day for a timelapse. Definitely recommended if you can buy it on sale!

Good for one full charge
