Who a 45W charger suits

A 45W USB-C charger is the small end of laptop charging. As a rough guide, small laptops, Chromebooks and tablets often need around 45 watts, and Microsoft lists 45W or 60W for many Surface models. A 45W charger is also a light, pocket-sized spare for a bigger laptop, to keep it topped up in a meeting or overnight in a hotel, even if it charges more slowly than the laptop's own. Every charger here has a UK three-pin plug, some of them folding flat for the bag.

What you will find here

  • Small GaN chargers with one USB-C socket, the plainest choice for a single laptop or tablet.
  • Chargers with a display that shows the watts going out, and on some the temperature and the phone's battery level.
  • Two-socket chargers for a laptop and a phone together, with the 45W shared between them.
  • Foldable plug pins on several, so they lie flat in a pocket or a tech pouch.

Many are described for phones and tablets as well as small laptops, because a USB Power Delivery charger serves all three.

How to choose a 45W charger

Check the watts on your laptop's original charger. If it says 45W or less, a 45W USB-C charger gives it the same power. If it says 65W or more, a 45W charger will still charge the laptop through USB-C, but more slowly, and while the laptop is working hard it may only slow the fall in battery rather than fill it. For an everyday charger for a bigger laptop, look at the 65W chargers instead.

On a two-socket charger, plugging in a phone takes some of the 45W away from the laptop. The product description gives what each socket supplies alone and together. Any USB-C cable will do at this power: certified USB-C cables carry at least 60W.

Questions people ask about 45W chargers

Will a 45W charger damage a laptop that came with a bigger one?

No. A USB-C laptop asks for the power it needs, and the charger gives what it can up to that. It simply charges more slowly.

Why does my Mac say "Slow Charger"?

Apple shows it when the charger gives less than that Mac needs to charge at its normal speed. The Mac still charges, more slowly.

Is a 45W charger enough for a Chromebook?

Chromebooks often need around 45W, but not all do. The figure on the charger that came with yours is the one to match.
