Phone Charger Wattage Guide
Charging numbers come from three places: your phone maker, the charging standard, and the adapter you plug into. This page collects the ones we have verified, with the source for each.
What are the published charging figures?
| Charging type | Published figure | Source |
|---|---|---|
| USB Power Delivery ceiling | Up to 240W (revision 3.1); 100W before | USB-IF |
| MagSafe, iPhone 18 Pro / Pro Max, 17 / 17 Pro / 17 Pro Max, 16 Plus, 16 Pro Max | Up to 25W with a 30W or greater adapter at 15V/2.0A or higher | Apple |
| MagSafe, iPhone Air | 20W peak | Apple |
| MagSafe, iPhone 16 and 16 Pro | 22.5W peak | Apple |
| MagSafe, iPhone 17e and iPhone 15 and earlier | Up to 15W with a 20W or greater adapter | Apple |
| USB-C to Lightning adapter, charging | Maximum 24W | Apple |
| Samsung Super Fast Charging | Needs a 25W or 45W Samsung-approved adapter on select devices | Samsung |
| Samsung 45W adapter | PPS 5.0 to 20.0V; PDO 9V, 15V, 20V | Samsung |
| Qi2 | 15W | WPC |
| Qi2 25W | Nearly 70% more than Qi2 | WPC |
What do the phones in our library list for wired charging?
These are the wired wattage figures on each phone page, as the maker lists them.
| Wired figure | Phones |
|---|---|
| 25W | Galaxy S26, Galaxy Z Flip8, Galaxy A16 5G, Galaxy A17 5G, Galaxy A27 5G |
| 30W | Moto G Power (2026), Razr (2026) |
| 45W | Galaxy S26 Plus, Galaxy S26 FE, Galaxy A37 5G, Galaxy A57 5G, Razr Plus (2026) |
| 60W | Galaxy S26 Ultra, Motorola Edge (2026) |
| 68W | Moto G Stylus (2026), Razr Ultra (2026) |
| Not published | The 17 iPhones, five Pixels, Galaxy S25 Ultra, Z Fold8 and Z Fold8 Ultra |
For the 25 phones with no figure, we could not verify a maximum wattage from the maker, and we do not guess one. Apple, for example, publishes a fast-charge claim rather than a wattage, and says the iPhone 17 can reach up to 50% in 20 minutes with a 40W adapter or higher and a USB-C cable. That claim is on the iPhone 17 page.
What wireless charging do the phones list?
| Wireless label | Phones in our library |
|---|---|
| Qi2 | 19 |
| MagSafe | 16 (all iPhones except the iPhone 16e) |
| No wireless charging listed | 6 (five Galaxy A phones and the Moto G Power) |
| Wireless named without a standard | 5 Motorola phones |
The labels overlap, since most iPhones list more than one. See Qi, Qi2 and MagSafe.
How do I use these numbers?
Find your phone on its page or its brand hub, then check the row for its charging type. Samsung says your device chooses the fastest speed it supports when plugged into a higher-rated charger, so a higher-wattage adapter is not a risk to the phone; see USB Power Delivery for how devices and chargers negotiate. For the oldest charging baseline, Wikipedia gives a default USB high-power device as 500mA at 5V, which is 2.5W, and Battery Charging 1.2 as 1.5A at 5V, or 7.5W.
Does the box include a charger?
None of the 41 phone pages records a charger in the box. Plan to buy or reuse one that matches your phone’s row, and read which charger is safe for my phone.
