Qi2 vs Qi2.2 vs MagSafe: Which Charger Do You Need?

Last updated: October 19, 2026. Checked against the Wireless Power Consortium, Apple, Google and Samsung documentation.

Wireless charger boxes now carry a confusing mix of labels: MagSafe, Qi2, Qi2.2, Qi2 25W, Qi2 Ready, “MagSafe compatible.” Some of these mean the same thing, and some matter a lot for how fast your phone charges. Here’s Qi2 vs MagSafe explained, which phones get 25W, and what to buy.

Qi2 vs MagSafe: are they the same?

Nearly. Qi2 uses the same magnetic charging design as MagSafe, and they work with each other. When the Wireless Power Consortium (WPC) announced Qi2 in January 2023, its Magnetic Power Profile was based on Apple’s MagSafe technology, which Apple contributed, as Macworld reported at the time. The WPC says Qi2 launched in November 2023 “with 15 watts of charging power,” and that within a year there were more than 1.5 billion certified Qi2 devices in the market.

The practical differences today:

Apple’s own charger blurs the line further. When it launched iPhone 17, Apple said “a Qi2 25W-certified MagSafe Charger will be available in a 1-meter length for $39 (U.S.) or a 2-meter length for $49 (U.S.),” per its newsroom.

What is Qi2.2 (Qi2 25W)?

Qi2.2 is the version of the standard that allows up to 25W, and it’s marketed as “Qi2 25W.” The WPC launched it on July 23, 2025, saying it “delivers nearly 70% more power than the original Qi2.” The version history on the WPC site describes Qi v2.2 as adding “support for up to 25 watt power transfer” and power modes that match the charger’s output to your USB-C adapter.

If a box just says “Qi2,” assume 15W. Look for “Qi2 25W” on the packaging if you want the faster speed, and check the WPC’s certified product database if you’re unsure.

Qi2 vs Qi2.2: which iPhones get 25W?

iPhone 16 Plus and later Pro Max-class models get the full 25W; some models peak lower. From Apple’s MagSafe Charger page and spec sheets:

To hit those numbers with Apple’s charger, Apple says you need a 30W or greater adapter (15V/2.0A or higher) and a MagSafe Charger with part number A3502, A3503, A2580 or A3250. Plug the charger in before you put the phone on it, so MagSafe can check it’s safe to deliver full power. Plugging in wired accessories such as headphones cuts the wireless rate, to as little as 7.5W on iPhone 16 models.

For iPhone Duo, Apple’s specs list “MagSafe wireless charging up to 25W” and “Qi2 wireless charging up to 25W,” and up to 50% in about 30 minutes with a 35W or higher adapter and a MagSafe Charger.

Does Qi2 work with Android (Galaxy, Pixel)?

Yes, but whether your phone has built-in magnets depends on the model.

• Google Pixel: Pixel 10 and Pixel 11 phones have built-in Qi2 magnets, which Google calls Pixelsnap. Google’s Pixelsnap page says its charger runs the Pixel 10 Pro XL and all Pixel 11 models at up to 25W with a 35W or higher adapter, and the Pixel 10, 10 Pro and 10 Pro Fold at up to 15W.
• Samsung Galaxy S26: Samsung sells Magnet Cases that have “a built-in magnetic ring” to align the phone with “compatible wireless chargers and magnetic accessories,” per its S26 page. In other words, you need the case for the snap-on experience.

That second approach is what the WPC calls Qi2 Ready: phones and cases “deliver the full Qi2 user experience when paired together in approved combinations,” according to its CES 2025 announcement.

Is Qi2 backwards compatible?

Mostly, but not guaranteed. The WPC’s specification history says Qi v2.0 products “are not required to be 100% backwards compatible with Qi 1.x Certified Products.” In practice, most Qi2 chargers will still charge older Qi phones and earbuds, slowly and without magnetic alignment, but check the listing if that matters. Going the other way, a Qi2 phone on an old Qi pad will usually charge, at Qi speeds.

Apple notes that wireless chargers under 10W, “like a Qi1-certified charger,” charge iPhone noticeably slower.

Qi2 vs MagSafe heat: which runs cooler?

There’s no published head-to-head, and both slow down when warm. Apple says MagSafe’s alignment “reduce[s] energy waste when compared to other wireless charging methods,” and that “if the battery gets too warm, software might limit charging above 80 percent.” Qi2 chargers use the same magnetic alignment, which is the main reason they waste less energy than older pads. Expect warmth at 25W either way. A charger with a fan, or simply a cooler room, helps more than the logo does. We haven’t measured temperatures ourselves.

Qi2 power banks and car chargers

The same rules apply: look for “Qi2 25W” if your phone supports 25W. A Qi2 battery pack snaps onto any MagSafe or Qi2 phone, but many still output 15W wirelessly. In cars, the WPC’s Qi v2.1 update added moving-coil chargers that find the phone’s coil automatically, which helps phones without magnets.

Which charger should you buy?

• iPhone 16 Plus, 16 Pro Max, iPhone 17 or 18 series, iPhone Duo: Apple’s $39 MagSafe Charger or any Qi2 25W-certified charger, plus a 30W+ USB-C adapter.
• iPhone 15, 17e or older MagSafe iPhones: any Qi2 charger. You won’t get more than 15W, so 25W isn’t worth paying extra for unless you’ll upgrade soon.
• Pixel 10 Pro XL or Pixel 11: a Qi2 25W or Pixelsnap charger with a 35W+ adapter.
• Galaxy S26: a Qi2 charger plus a magnet case.
• Mixed household: one Qi2 25W charger covers everyone, at whatever speed each phone accepts.

Be wary of uncertified “MagSafe compatible” pads. A magnet alone doesn’t make a charger Qi2, and without certification you can’t know what speed you’ll get.

Verdict

Qi2 and MagSafe are now effectively the same system, and Apple’s current MagSafe Charger is a certified Qi2 25W charger. What matters is the number: 15W chargers for older phones, Qi2 25W for anything from iPhone 16 Plus and Pixel 10 Pro XL onward. Buy a certified Qi2 25W charger, pair it with a 30W or larger adapter (35W for Pixel), and it’ll serve your next phone too.

FAQ

Are Qi2 and MagSafe the same?

Almost. Qi2 is the open standard based on Apple’s MagSafe magnetic design, so Qi2 chargers snap onto and charge MagSafe iPhones, and Apple’s current MagSafe Charger is Qi2 25W-certified.

What’s the difference between Qi2 and Qi2.2?

Original Qi2 tops out at 15W. Qi2.2, branded Qi2 25W, raises the maximum to 25W and adapts power to your USB-C adapter.

Which iPhones support 25W wireless charging?

iPhone 16 Plus, 16 Pro Max, iPhone 17, 17 Pro, 17 Pro Max, iPhone 18 Pro, 18 Pro Max and iPhone Duo, with a 30W+ adapter. iPhone 16 and 16 Pro peak at 22.5W, and iPhone Air at 20W.

Does Qi2 work with Samsung and Pixel phones?

Yes. Pixel 10 and 11 phones have built-in Qi2 magnets. Galaxy S26 phones need Samsung’s magnet case to snap onto Qi2 chargers.

Is Qi2 backwards compatible with older Qi devices?

Usually, at lower speeds, but the WPC doesn’t require Qi2 products to be fully compatible with older Qi 1.x devices. Check the product listing.

Do I need a special power adapter for 25W?

Yes. Apple specifies 30W or more (15V/2.0A) for 25W MagSafe charging, and Google recommends 35W or more for 25W on Pixel.
