I wanted a second charger at the office so I didn't have to carry a charger around with me. It's a charger, it charges batteries in an hour or two.

Charger works great and pretty fast at two hours full charge. I only wish it were cordless with flip-out prongs for easier storage and carry. Who wants to have to keep up with and fool with a cord? That would earn it five stars from me.

It works fine, but I have some suggestions for improvement. My charger for my Flashpoint flash is nicer with rubbery grippy feat so it doesn’t slide off a desk and also has 4 different led lights to indicate 20%, 50%, 80%, and 100% charge. It’s way easier to read than counting flashing dots on the Olympus charger.

This is the charger for the large BLH-1 battery. It's not heavy, but adds something the size of a compact camera and a cable when you pack your gear. Why can't we have in -camera charging - the USB-C in the OM-D E-M1II should be perfect for that. The BCH-1 has also very bright LEDs - and can be used as an additional night-light for your hotel room. Or you need to cover it somehow.
