Does the job. I have purchased other BM batteries and chargers for two other brands of cameras we own. I’m an electronics technician with more than 50 years experience. So far these chargers work fine and the batteries perform as expected. No complaints. Price is very competitive compared to other options.

Works as expected

In my previous review, I commented that the charger and/or batteries didn't appear to charge properly. I had plugged the supplied USB cable into a small power block supplied for iPhones. When I changed the power block to one provided for iPads (slightly more power (amps) output), the charger worked "as advertised". I had failed to first notice the note on the back of the charger box stating the minimum "input power" requirement was 2.1A @ 5VDC. Since a power block isn't supplied with this charger, I had to use one of mine. If you've purchased one of these chargers and the indicator lights flash "red" after inserting batteries, check the power supply "bloc" first. This info is printed on the power bloc, usually in very fine print, before contacting this device's customer support with your problem. Not all power blocs provide the required power this charger needs to operate normally.

Worked really well and the batteries made our camera behave like new!

I was looking for an external charger for my Olympus batteries. I don't like to charge the batteries inside the camera, and this charges two batteries at a time. It comes with a pair of batteries, which I will not use. I don't like to put cheap batteries in my expensive cameras and only use original manufacturers batteries. That having been said, it charge my two batteries quickly and I am very pleased with this charger.

So far so good. Charges my batteries well. I haven’t tried the non OEM batteries that came with the charger but the charger was the reason for my purchase.

The batteries seem to last as long as the OEM battery, which is good enough. I have not owned it long enough to assess how many charge cycles the batteries will take. As for the charger, it works fine even with two batteries, if the USB port can supply enough current. The minimum standard is only 0.5 amps, which is not enough. You'll need about 2 amps for the charger to work properly. Most computer USB ports will not supply 2 amps, but many plug-in-the-wall USB supplies will. Just look at the label on the USB supply and it will say how much current it will output.

I’ve noticed as others mention that replacing a charged battery with a depleted battery doesn’t reset to charge again. You may need to unplug from the power source for a minute to clear this effect. It isn’t necessary to function but would be nice to have more than a binary red/green LED to monitor if charged. A couple more LEDs to indicate % would be useful, especially if you have a few batteries and want an indication of which needs charging the most without swapping them in and out of the camera to figure this out. Otherwise, this does what the description states. Have not tested battery life yet other than to say they last about 8hrs when my camera is set to log GPS tracking and each battery performs similarly. This rough test was at room temperature with a few zoom in/out every hour and no photos captured (admittedly not a great test).
