The Promate GANPORT-140W is a mains charging station with a total output of 140W, split across three USB-C Power Delivery ports and one Quick Charge USB-A port. A laptop, a tablet and two phones can all be plugged in at once, which is the difference between one adapter on the desk and a handful of separate bricks.

The lead USB-C port runs Power Delivery 3.1 and steps all the way to 28V at 5A, which is where the 140W figure comes from. It also handles 5V, 9V, 12V and 15V at 3A and 20V at 5A, with PPS across 4-11V at 5A and 4-21V at 4A for devices that negotiate their own voltage.

The second USB-C port tops out at 20V and 5A for 100W, and supports PPS across 4-11V at 5A and 4-21V at 4A. That is full-speed charging for most work laptops, so two machines can be running off the same station without either dropping to a trickle while the other is busy.

The third USB-C port peaks at 20V and 1.5A for 30W, stepping through 5V and 9V at 3A, 12V at 2.5A and 15V at 2A, with PPS from 4V to 11V at 3A. It is sized for phones, earbuds and tablets, which keeps the higher-wattage ports free for the machines that genuinely need them.

A Qualcomm Quick Charge 3.0 USB-A port supplies 5V at 3A, 9V at 2A or 12V at 1.5A for 18W, which Promate rates at up to four times faster than conventional charging on compatible devices. It keeps older phones, headsets, controllers and power banks on their original Type-A cables.

A 1.8m 240W PD cable is supplied in the box, rated well above the station's own maximum so it is never the limiting factor in the chain. The length matters as much as the rating: 1.8m reaches from a wall socket to a laptop on a desk or a bed without an extension lead in between.

GaN technology keeps the station compact while improving efficiency and reducing heat, and the upright stand lets it sit vertically so it occupies very little desk area. It plugs straight into AC at 100-240V, 50-60Hz and 3A, with protection against high temperature, over-current and short circuits, plus adaptive charging that tunes output per device.
