ONITOON 150W 4-Port USB-C GaN Wall Charger 747

150W GaN Wall Charger

The ONITOON 747 charger delivers up to 150W total output across four ports using gallium-nitride technology. It targets users who need to charge multiple USB-C devices such as laptops, tablets and phones from a single compact wall outlet. The foldable plug design makes it practical for travel or desk use. ActiveShield 2.0 monitors temperature continuously to keep charging safe.

Capacity and headroom

A single USB-C port can supply up to 100W, enough for most modern laptops, while the remaining ports share the remaining headroom for phones or accessories. Connecting two high-power laptops simultaneously approaches the 150W ceiling, so the charger will throttle each port to stay within its total limit. Four low-power devices such as phones and earbuds charge comfortably without hitting the maximum. The unit is 38% smaller than a typical 140W charger, so it fits tight outlets.

USB-C power delivery limits

The charger relies on USB Power Delivery negotiated over USB-C cables, so actual speed depends on the cable rating and the device request. It cannot exceed 100W on any single port regardless of the 150W total rating. Devices that require proprietary charging protocols beyond standard USB PD may not reach their maximum speed. Buyers who need more than 100W on one port or more than 150W total should look for a higher-rated solution.
