Today, we are testing the 'Liitokala' battery charger, model LiiM4S.I It has battery capacity testing. It features four independent charging channels and also includes a USBC connection.

The device charges all common battery types – lithiumion, nickelmetal hydride, and apparently even obsolete nickelcadmium batteries.

The device requires a 2amp USB power source. It charges two batteries at 1000 milliamps and multiple batteries at 500 milliamps. It can discharge a battery at either 250 or 500 milliamps. It can be used as a powerbank too.
