Ultra-compact 45W GaN charger

The Ugreen X840 Nexode Air is a 45W USB-C charger built on gallium-nitride technology. Its 1.21 × 1.21 × 1.42 inch cube and foldable prongs make it small enough to slip into a pocket or a slim laptop sleeve. It targets users who want fast charging for phones, tablets and ultraportable laptops without carrying a bulky brick.

Premium texture and foldable plug

A starry silver-grey matte finish covers the body, while the USB-C port panel uses translucent frosted glass. Twenty-two precision-engraved ridges on the lower section improve grip when inserting or removing the charger. The foldable plug lies flat against the cube, preventing snags on cables or fabric during daily transport.

Single-port 45W ceiling

Only one USB-C port is available, so simultaneous charging of multiple devices is not possible. The 45W maximum suits smartphones, tablets and thin-and-light notebooks, but it cannot drive larger laptops that demand 65W or 100W. Buyers needing to charge a phone and a laptop at the same time, or power-hungry workstations, should look at multi-port or higher-wattage alternatives.

Questions about this item

What USB-C standard does the 45W output cap at in practice?

The charger delivers up to 45W at 20V and 2.25A over its single USB-C port.

What physical space does the 1.21 × 1.21 × 1.42 inch body with foldable plug need to fit?

It occupies a cube of roughly 1.21 inches per side with the prongs folded, so it clears tight outlets and packed bags.

How is the X840 installed and what step do people miss?

Unfold the prongs, plug into a 100–240V socket, then connect a USB-C cable; the step often missed is ensuring the cable supports the 45W rating.
