Aukey has announced that its new 100 watt (W) charger with a USB type C port is now available to pre-order. This Omnia 100W is based on gallium nitride (GaN) technology, which leaves it with a depth of 32 millimeters. This, according to the OEM at least, makes it more portable than a comparable MacBook Pro power-brick.
