just received it. tested it quickly to make sure everything works and all good. The 16000 is on the heavy side but that is to expect at this price point. If everything keeps working for years to come then this is an unbeatable deal. 20000 total for +/- 20$ when on sale is simply crazy good deal. To be on the safe side lets say the 16000 one is around 11k or 12k and the 4k stays at 3.5/4k this is still the best deal around. will buy another set next time it comes on sale for sure.(no more worries during a camping trip with 2 of these. Can do a week of movie watching in the woods. 2-4 movies a charge on my S7 x min. 20k extra juice = great camping nights) P.S: like with any powerbank i always recommend using your own mobile cable rather then the provided ones. There always on the cheap side and never work.(if in this case it works it will probably die after charging my mobile once as per the usual.) The cable isn't worth a bad review nor a return, it is to be expected and if you expect a good wire, well, to be nice, your delusional at this price. You buy the powerbank for extra power and not the cable.(all cables with powerbanks that companies give are cheap. Unless your powerbank is 200$ then i hope you get a good one.

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.

Excellent

Great

Works pretty well. Seems to hold a charge for a decent amount of time (a few months charged but unused).

excellent price and quality
