2.7A per port
Each port delivers a maximum current of 2.7A, and doesn't throttle when all ports are in use, so you can plug in 4 iPads at max speed. It detects and optimizes charging speed by adapting to your device's particular charging scheme.
Each USB port is electrically independent and contains robust circuitry with overheating, static discharge, short circuit, and reverse polarity protections. This means it protects itself and your devices from harm.
Wide input range
It takes DC input ranging from 7V to 17V, and can be used anywhere with wall outlets, car power ports, lead-acid batteries, DC-output solar panels, and lithium-ion battery packs (2S, 3S, and 4S).
It has an integrated wattmeter so you don't need a multimeter to know how much power you are drawing devices.
Mechanically, it is built with anodized aluminum top and bottom plates, and the middle layers are made of FR4.
