Twelve South ButterFly SE
$70 under your budget
Folds to the size of an AirPods case and still charges an iPhone and Watch at once — the most compact multi-device charger across 12 sources.
Fit ledger — need → measured evidence
■ The catch — co-equal billing, always
You are paying $80 for 15W. Belkin's 25W 2-in-1 folds flat too, charges the phone at full speed and puts a 45W brick in the box for $59.99 — the ButterFly SE ships bare. The extra $20 buys size, and nothing else.
Dealbreaker? Belkin's 25W 2-in-1 at $59.99 if pocket size is not the point ↓

Traps — this verdict avoids
Why the Twelve South ButterFly SE is right for you
It avoids every trap below — and for anyone, under $150, it is the pick because it delivers:
"Qi2" means four different things
Qi2.2 (sold as "Qi2 25W") is 25W magnetic. Plain Qi2 is 15W magnetic. "Qi2 Ready" is a magnet ring bolted to a charger that is not certified at all. Plain Qi is neither. Only Qi2 and Qi2.2 are verifiable in the Wireless Power Consortium database.
Your phone caps the speed, not the charger
25W needs a Qi2.2 charger AND an iPhone 17, an iPhone 16 on iOS 26 or newer, a Galaxy S26 Ultra or a Pixel 10 Pro XL. The base Galaxy S26 is capped at 15W and still needs a magnetic case. Everything older tops out at 15W or 7.5W.
The wall brick is usually missing
Most 25W chargers need a 30W+ USB-C PD adapter to actually reach 25W and ship without one — add $20-30. The Belkin 25W pad, the Spigen 2-in-1, the UGREEN 15W pad and the Twelve South ButterFly SE all arrive bare.
