Used to power 12V battery chargers this unit is able to provide a maximum of 20amps of current through either one of the twin outputs. This can be particularly useful when using two different chargers to charge different battery types i.e Lipo and NiMh.


Been using this along with my Mystery B6 for about 5 months as previously was using a multi voltage supply that would only allow 0.9amps at 12V for about 2 hours before over heating and turning off, Completely useless when charging a 2250mah 3 Cell Lipo! Took 3-4 hours to charge one battery! This however allows me to charge at 1C easy on two chargers with plenty to spare if am in a rush. 100% Recommend this to anyone.
