The ToolKitRC M4Q is a 4in1 charger that has 4x 50W charging circuits inside.  This allow you to balance charge 4 batteries at the same time.  This charger also features an integrated power supply so you can just plug it into your nearest wall socket.  It also includes a XT60 input connector to enable in the field charging.

We have found that out of the box (or after a firmware update) you will likely need to calibrate the voltage on the charger before use, it takes 3 minutes but you will need a voltmeter.  We have a quick guide showing how to do that here – Toolkit RC voltage calibration guide.
