MPD’s AS234A-A is an upgraded version of its AS232 with total output increased from 2.1 A to 3.4 A. Enhanced water-resistant design with no assembly gap on the front face means fewer chances of water getting in. Raised surface also helps prevent water from getting into the USB port. The specially designed sealing PVC cap protects the chargers against even powerful water jets (when sealed). Full compatibility with up to 2.4 A charging matches latest iPad standard. Class leading 3.4 A charges multiple devices at full speed and provides reliable output with EMC suppression and full short circuit/overheat protection.
