Cuktech 30 Power Bank Review

Cuktech 30 40000mAh 300W power bank with dual 140W USB-C PD3.1 output, 2 USB-A ports and 20W Qi wireless charging pad, intelligent cooling fan.

A high-capacity GaN power bank built for road warriors: 40,000mAh of battery backing a 300W total output across 5 simultaneous charging paths (2x USB-C, 2x USB-A, plus a 20W wireless pad). Dual 140W USB-C ports can each match a 16-inch MacBook Pro's stock charger, and the whole pack refills in about 2.5 hours thanks to 140W input.

Why it stands out

300W of combined output across 5 ports/pad is rare at this capacity tier, and the auto-grade battery cells plus PWM-controlled cooling fan keep thermals in check under sustained high-power use.

Charging performance

Either USB-C port can deliver up to 140W, enough for the highest-power USB-C laptops, and 2 devices can pull 140W simultaneously if total draw stays under 300W.
