iCharger 458DuoIt may look familiar but don't be fooled by appearances the all new 458Duo is the most powerful iCharger yet, capable of 45A charge rates per channel and a full 2200W of output. Upgraded top to bottom from its 308Duo beginnings, the 458Duo offers beefier connections on both the input and output in order to handle the higher current levels, and features the new open port style balance connections that do away with the need for separate balance boards.
