Very satisfied, I consider it very good that it gives you the ability to use your favorite 18650 batteries, as well as the fact that it also works with just one battery

Incredibly convenient as a power bank since it has a digital charge level indicator and most importantly: despite the small capacity it can acquire with the 2 18650 batteries it carries, you can change them whenever you want in case you find higher capacity ones or they show fatigue from multiple cycles. I have a Galaxy J5-2017 and it charges it only once, which is enough for me. It is also quite fast as a charger. Recommended!

A very good charger, with battery rejuvenation for batteries that have dropped to 0 volts. I consider a 2 amp USB charger necessary in order to fully exploit its capabilities. I really liked that it is coated with non-slip varnish and does not slip from the hands. Its size is slightly larger than the batteries, it is lightweight, fits everywhere, even in the shirt pocket. You have a power bank everywhere. A very good purchase.
