Banggood

1st time ordered from Banggood. Fast delivery, received as described. works on all different types of 18650 batteries including laptops batteries and able to charge just like portable charger. Highly recommended!

솔직히 싸지만 품질이 너무 떨어집니다 외관은 그렇다쳐도 하나는 완전불량에 나머지는 구멍이 맞지 않아서 들어가지도 않고 들어가게 할려면 뜯어서 내부를 파던지 이것도 안되면 그냥 앞쪽을 크게 뜯어내야 하네요

its ok, delay delivery

work very well.. but it's too tight. but oke.

The most important feature of these powerbanks is, in my view, the short circuit protection, as many of us have faulty wires, and as li-ion cells can easily provide currents in excess on 10A. This one does have short circuit protection, which actively resets once the short is resolved. As li-ion cells get damaged if discharged below ~3v, it's also important that these cases disconnect the power completely, so that no further discharging may occur (poor quality ones stop boosting the voltage up to

Fast shipping and delivery, unbeatable price !!! It works JUST FINE. I have already used it both as a power bank and a charger for my 3.7 V Lion batteries ! I WANT MORE OF THEM !!!! Recommended for SURE !!! Just finished the review and i go now to order the next one ... Thank you BangGood !

good deal for those who are interested in discovering how those USB power banks are made. For people interested in technical details, this case is based on a HT4928S chip made by HOTCHIP, which works as charger and DC-DC converter. Datasheet available only in chinese, but schematic easy to understand.

All right, after a call from the Italian post office that said that the package was destroyed and was not delivered at the end it arrived perfectly but was put back in another envelope and then inside its original that was heat sealed again. Banggood's assistance was perfect in following what was happening. The product is great already in the past I had bought it and it worked well. Thanks Banggood.

a good one I'm sure is not 1amp output but is enough for my application the blue led confuses me sometimes is steady other times blink I don't know how
