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.

Great little battery pack, only if you get it on discount! I own several small power banks similar to this one (some 4000mAh, some 5000mAh, etc) to power a Sony RX100 camera externally. This works well with it, owning to the claimed capacity. Only time will tell if the batteries hold up well (some of those cheapish power banks die quickly after few charge/discharge cycles). So far so good, this one works!

Very good balance with excellent quality and priceNo comment
