Power multiple gadgets simultaneously with this four-port Native Union smart hub bridge. It provides optimal charging speed for each connected device, with up to 5.4 amps of total output when its single USB-C and all three USB-A ports are used. The Smart IC technology of this Native Union smart hub bridge protects against overvoltage and short circuit.
A: Take the listed OUTPUT current (1A, 2A, etc.) and multiply it by the OUTPUT voltage (5V) and you'll get the TOTAL POWER it can supply. IOW, if it provides 2A output current, the total output power is 10 watts (through ONE USB socket). If you plug MORE THAN ONE ITEM into the adapter (up to 4), take the TOTAL output power, divide it by the number of devices plugged in, and that'll give you the MAXIMUM power available for each device. If you still have questions, look up "Ohm's Law" on the internet - you'll get a lot of formulae for use. :)
