Compact GaN charger for phone and light laptop users

The Ugreen X840 delivers up to 45W through a single USB-C port, enough to fast-charge recent iPhone and Galaxy models or top up a MacBook Air. Its foldable plug and 1.21 × 1.21 × 1.42 inch cube make it easy to slip into a pocket or small bag for daily carry.

Steady 45W output with thermal management

GaN circuitry and Thermal Guard technology keep the charger running at its rated 20V 2.25A without throttling during a full phone charge cycle. The 8 active and passive protections guard against over-temperature, over-voltage and short-circuit events even when the unit is left plugged in for extended periods.

Plug in and go with no driver setup

The foldable prongs lock flat for transport and swing out for a secure fit in 240V sockets worldwide. A frosted glass panel over the USB-C port resists dust, while 22 precision ridges on the base improve grip when removing the charger. No cables are included, so buyers must supply their own USB-C lead.

Questions about this item

Does the 45W GaN charger stay cool when it runs all day at full load?

Thermal Guard technology and eight active and passive protections prevent overheating during continuous use.

What cable do I need to get 45W from the single USB-C port?

A USB-C cable rated for at least 45W and 20V/2.25A is required.

Will the foldable-plug design work with the UK travel adapter I already own?
