Q. What is the difference between the MXS15 and PRO15S

The PRO15S is the replacement for the MXS 15, the internals of the PRO15S are an all new design that allows for running at peak power output without any derating for heat dissipation. It also includes a Lithium charge profile.

Otherwise it still has all the same features in the same sized housing as before but in the updated black colour.

Normal features included:

IP44 rated

2 year warranty

Alligator clips (no comfort plug connectors because of its high power output)

Normal Charge

Power Supply Mode

Recondition Charge Mode

15A output at 14.4 volts

DC output voltage temperature compensation
