If you're shopping for a Qi2 wireless charger, don't trust the words on the box. Look the product up in the Wireless Power Consortium's certification database first. Then check that you have a power adapter big enough to run it.
The Wireless Power Consortium (WPC) is the industry group behind the Qi standard. WPC's own guide to Qi2 25W charging stations makes the case for checking the database rather than the packaging. It is the official source, so this guide relies on it. Plenty of retailer and charger-maker blogs cover the same ground, but they sell chargers, so treat them as secondary.
"Qi2 compatible" is not the same as "Qi2 certified"
This is the label trap to watch for. According to WPC's guide, "Qi2 compatible" and "Qi2 enabled" do not mean "Qi2 certified." A listing in WPC's public database is what shows a product actually passed certification.
In practice:
- "Qi2 certified", with a matching database entry, is what you want.
- "Qi2 compatible" or "Qi2 enabled" with no database entry is a marketing claim you can't check. Treat it as uncertified.
The same habit helps when you buy smart-home gear. Our guide to choosing Matter devices covers a similar gap between what the box says and what is certified.
What a real Qi2 25W listing shows
WPC's guide says Qi2 25W certification can be looked up in a public WPC database. It says a genuine 25W listing shows three fields:
| Field | What a 25W charger should show |
|---|---|
| Version | 2.2.1 |
| Power Profile | MPP25 |
| Potential Load Power | 25.0 |
If a charger is sold as "Qi2 25W" but its listing doesn't show all three, it isn't the 25W product the box suggests. If you can't find a listing at all, see the compatible-versus-certified point above.
This is also the practical answer to "Qi2 vs Qi2.2." The 25W listings WPC describes carry Version 2.2.1. So for 25W charging, the version field in the database is what counts, not a "Qi2.2" sticker.
Big brands still sell 15W Qi2 chargers
Don't assume a well-known brand means the faster tier. WPC's guide notes that some charging stations from major brands are only Qi2 15W. A Qi2 15W charger can be fully certified and still not be a 25W charger.
So when you weigh Qi2 25W vs 15W, check the Power Profile and Potential Load Power fields for the exact model you're buying. A brand's other products can be listed differently.
The power adapter decides whether you get 25W
This is the part most people miss. WPC's guide says a 25W station needs a 30–40W or larger power adapter. Without one, it charges more slowly and gives no warning.
That means a certified 25W charger plugged into an old, small phone brick can quietly perform like a slower one. Before you buy:
- Check whether the charger comes with a power adapter.
- If it doesn't, check the wattage printed on the adapter you plan to use.
- If that adapter is under the 30–40W range WPC gives, budget for a bigger one.
If you're also powering chargers away from a wall outlet, our guide to choosing a portable power station covers matching output to your devices.
What this guide can't tell you yet
Some questions people search for aren't covered by the official source used here:
Which phones support 25W Qi2. Phone support depends on the phone maker. Check Apple's, Google's or Samsung's own support pages for your model rather than a charger listing.
Specific models to buy. Product lineups change, and a recommendation is only as good as a dated database check. Look up any model you're considering.
How to choose
For most people buying a Qi2 wireless charger:
- You want the fastest Qi2 charging: buy a charger whose WPC listing shows Version 2.2.1, Power Profile MPP25 and Potential Load Power 25.0. Pair it with an adapter of at least the 30–40W range WPC's guide gives.
- Your phone can't use 25W, or you just want a bedside charger: a certified Qi2 15W charger is a reasonable choice. Still check that it has a database listing.
- The box says only "compatible" or "enabled": skip it unless you can find it in WPC's database.
The box tells you what the seller wants you to believe. The database tells you what passed certification. Check the database.
