Will this charge my ThinkPad at full speed?

If your ThinkPad charges over USB-C and accepts 140W, yes. Models capped at 65W or 100W will charge fine but slower, limited by the laptop.

Does it work with non-Lenovo laptops?

It follows USB-C Power Delivery, so most USB-C laptops, tablets and phones charge from it. Devices that need more than 140W, or that use a proprietary barrel or slim-tip connector, will not.

The adapter and a 39.36-inch (1 m) USB-C cable. No wall cable is needed since the plug is built in.

Is $36.99 a good price?

It is low for a 140W GaN charger; Lenovo's own 135W and 140W adapters usually sell for more. Seven stores list it new, so compare before buying, and check that the eBay listing is a genuine Lenovo unit.

Can I charge a phone and a laptop at the same time?

No. There is one USB-C port, so it charges one device at a time.

Our take on the Lenovo 140W USB-C GaN Adapter

Lenovo's 140W USB-C wall charger uses gallium nitride to keep the brick small for its output. It ships with a 39.36-inch (1 m) USB-C cable and is aimed at ThinkPad laptops that draw up to 140W over USB-C. At $36.99 at eBay as of November 5, 2026, it sits well below what Lenovo's own 135W and 140W adapters typically cost, so it is a cheap way to get a full-speed charge.

Pros

140W output covers most ThinkPad USB-C laptops at full speed
GaN design is smaller and lighter than older barrel-style bricks
Includes a 1 m (39.36 in) USB-C cable
Works with USB-C Power Delivery devices beyond ThinkPads
Low price for a 140W charger

Cons

Single USB-C port, so it cannot charge two devices at once
140W needs a USB-C port rated for that input; older ThinkPads with slim-tip or barrel ports need an adapter
Cable is only about 1 m, short for reaching a floor outlet
No foldable plug, which makes it bulkier in a bag
