Questions and answers

Will this charge a 140W laptop at full speed?

It delivers up to 140W over USB-C at up to 28V, so laptops that accept 140W over USB-C Power Delivery will charge at full rate. Check that your laptop's USB-C port is rated for that wattage; some models charge slower over USB-C than over their barrel connector.

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

Only through one port. With a single USB-C output, plugging in a phone means sharing or splitting the 140W, and most phones will negotiate a lower voltage. A small multi-port charger is a better fit if you routinely charge two devices.

Is it smaller than a standard laptop power brick?

Yes. GaN components let it run at 140W in a smaller, lighter body than older silicon bricks of the same output, which is the main reason to pay more for it. Exact dimensions are not listed, but expect a palm-sized block rather than a brick.

What cable comes in the box?

A 39.37-inch (about 1 meter) cable is included. Make sure it is rated for 140W and 28V; a lower-rated cable will cap charging speed.

Is $79.99 a good price?

At $79.99 at Lenovo as of November 5, 2026, it is at the low end of its recent range across the two stores listing it new. Comparable 140W GaN chargers from other brands often sell for less, so the premium buys Lenovo branding and support more than raw specs.

Does it work with non-Lenovo laptops and phones?

It follows USB-C Power Delivery, so it should charge other USB-C laptops, tablets and phones at whatever wattage they negotiate. Very high-wattage non-Lenovo laptops may need a specific charging profile to hit their maximum.

Where is the Lenovo 140W USB-C GaN Power Adapter cheapest?

At Lenovo, for $79.99, as of our latest check.
