ProMaster USB Dually Charger for Olympus BLN1

I was pleasantly surprised by how compact this charger is for handling two batteries at once. The ability to charge just one when needed is a nice touch, and it consistently tops off both batteries without any fuss.

The dual slots are tight but reliable, so I can toss two BLN1s in and forget about it until the indicator lights flip. It’s small enough to slip into my camera bag’s side pocket without bulging, which is exactly what I needed for day trips.

Charging two BLN1s at once has cut my prep time in half before shoots, and the compact footprint slides right into my camera bag without taking up much room. The single-slot option is a nice touch when I only need one spare topped up.
