A 10.8A, 4 port USB charger with a wattmeter and adaptive intelligent charging.
It works by taking any DC input between 7V to 17V, from an AC/DC adapter or car adapter. It 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 then drops the voltage down to 5V and intelligently adapts to match the maximum current the device being charged would accept. We believe it is the most powerful 4-port USB charger at 10.8A. No device is throttled when every port is in use.
