All Rounder in Small PackageReview by Felix
Charged all kind of batteries from NiMH, Li-ion (3.7v and 3.85v), Li-fe, IMR, in a small compact form. Works well to charge my Li-ion and NiMh.
It is not premium build, but it's solid and did not get hot on my daily use. (Posted on 14/08/2019)
Works OK, but has a confusing jumble of lightsReview by Ken
When you put the battery in it works out which type it is. Then all to lights come on so I just ignored them and left it to do its thing. Charged OK (Posted on 4/08/2017)
