Galaxy S26 Ultra 25W wireless fast charging won’t work unless you do this

Samsung bumped up the wired and wireless charging speeds for the Galaxy S26 Ultra. The device is now capable of wirelessly charging at 25W, a significant improvement over previous models.

However, some users have found that their device doesn’t charge wirelessly at 25W. That’s because they need to use a faster wired charger for the charging pad.

The wireless charging speeds were increased for both the Galaxy S26+ and the Galaxy S26 Ultra at 20W and 25W, respectively. The relevant wireless charging pad from Samsung that can support charging devices at these speeds is the EP-P2900.

Samsung guides that to hit wireless charging speeds of 25W on the Galaxy S26 Ultra and 20W on the Galaxy S26+, the wireless charging pad must be connected to a 45W or higher charger.

If you use a 25W charger with the wireless charging pad, for example, then it will only charge your device wirelessly at 15W. This limitation also applies to third-party Qi 2.2 charging pads.

This means you need to upgrade your charging adapter, if you don’t already have a 45W one, before buying this wireless charger. That’s going to add up, as the EP-P2900 wireless charger costs $49.99 and a 45W charging adapter costs an additional $49.99.

Fortunately, Samsung sells a bundle that includes an EP-P2900 wireless charger with a 45W charging adapter for $74.99.
