Convenient Little Charger

By Mariah
Rated 5 out of 5
Date: 2026-08-31

An easy to use charger that does not take up much space. No complaints about it, and it has continued to work since I've received it (admittedly, only two or so weekes ago). It is easy to pack into camera bags alongside my camera by disassembling the charging block, cord, and head that connects to an outlet.

It works if battery is properly inserted

The battery goes in vertically over the contacts. I was used to a horizontal battery placement for my SONY NEX 7 battery charger.
