High capacity Li-ion battery which do not require dedicated charger. Simple use a phone charger or any similar which provide 5V USB power and connect it to the micro USB slot on the battery.Charging time depends on the supplied charging current.This battery can be charged by normal Li-ion battery chargers as well.The capacity is really amazing.

These batteries are pretty popular with the vape culture and I’d have to say that these are pretty good because of the pricing and easy access. The batteries tend to get pretty warm during charging but that’s the only issue I’ve noticed. The batteries don’t drain super fast and to your gain they charge pretty quick too!
Suggestion:
- no cons

Very useful, that USB connector is a great and very usable idea. Strong battery. Came very well packaged.
Suggestion:
Nothing at all.

The ability to charge it without needing a charger is fantastic.It claims to use Panasonic cells.I'm happy with it, I use it on a Convoy flashlight and it performs perfect
Suggestion:
I have no cons to this product, I have used it for a long time now and can't find any problem

Versandzeit war absolut im Rahmen. Artikel entspricht der Beschreibung. Benutze die Akkus in einer BLF A6 und einer Convoy S2+ 365nm Nichia UV. Dort passen sie rein. Etwas knapp, aber es geht. Für mich eine gute Lösung um auf Reisen kein Ladegerät mit nehmen zu müssen.
Suggestion:
Nothing so far.
