Wireless charging and USB-C power compatibility

Match the phone, charger, adapter and cable before you buy.

Start with what your phone accepts. Then check the wireless standard, adapter and cable together. Qi 2.0 added Magnetic Power Profile, and Qi 2.2 added up to 25 W. USB PD can reach 240 W. A USB-C plug alone does not prove support for USB PD, USB 3.2 or USB4.

Current identity: Shop Fiora Charge Lab is an independent consumer reference about charging compatibility. It publishes guides and does not sell hardware, hold stock or collect payments. Two separate archive searches found no recoverable earlier site for shopfiora.net, so this is a new publication rather than a reconstruction of a past shop.

Four parts decide the result: adapter, cable, charging surface and receiving device. A large number on one part cannot override the others.
Qi 2.0Magnetic Power Profile

WPC says Qi 2.0 introduced the Magnetic Power Profile.

Qi 2.2up to 25 W

WPC says Qi 2.2 added up to 25 W.

USB PDup to 240 W

USB-IF says USB PD can reach 240 W, but actual power depends on all components.

01

Start with the phone's accepted input

The phone sets the ceiling for any charger. A wireless charger can only supply power the phone accepts. A USB-C adapter can only negotiate a USB PD level the phone requests. A higher number on a charger does not force extra power into the phone.

Apple currently says compatible iPhones can reach up to 25 W with compatible MagSafe hardware and a 30 W-or-greater adapter. This claim covers compatible iPhones and specific MagSafe hardware. Actual power varies with the model and conditions. Other phones may use Qi 2.2 up to 25 W or a lower level.

Write down the wireless standard and the wired standard your phone supports before comparing products. If the phone's documentation gives a maximum wattage, treat that as the target for both the wireless and wired path.

02

Read the wireless specification, not the marketing name

The WPC maintains the Qi specification. Qi 2.0 introduced the Magnetic Power Profile, which is why some chargers use magnets to align the phone. Qi 2.2 added up to 25 W. A product may use a Qi name without delivering the highest level of the current specification.

Use the WPC certified-products database to confirm that a charger model has a Qi listing. Check this source instead of relying on a store description or image.

A Qi 2.0 Magnetic Power Profile charger may still work with a phone that lacks magnetic alignment. Do not assume that the phone has the magnetic profile. Check both the phone and charger before paying for this feature.

Treat USB Type-C as a connector, then verify PD

USB Type-C names the connector. It does not prove support for USB PD, USB 3.2 or USB4. A cable with a USB-C plug on each end may carry USB PD power. It may also be limited to a lower power level. The plug shape alone does not tell you the power limit.

USB-IF says USB PD can reach 240 W, and actual power depends on all components. The adapter, cable and device must all support the negotiated level. If one part of the chain is lower, the system will use the lower level or fail to charge at the expected speed.

For a phone that uses USB PD, choose an adapter and cable rated for at least the phone's requested level. If the phone requests 30 W or more, the adapter should meet that request. The cable should be rated for the same power level or higher.

How to match your kit without overbuying

  1. 01

    Find the phone's accepted maximum

    Check the phone maker's current guide for wireless charging and USB PD wattage. Apple says compatible iPhones can reach up to 25 W with compatible MagSafe hardware and a 30 W-or-greater adapter. Actual power varies by model and conditions.

  2. 02

    Confirm the wireless specification

    Look for the Qi specification the charger is listed under. Qi 2.0 introduced the Magnetic Power Profile and Qi 2.2 added up to 25 W. Use the WPC certified-products database to check a model rather than trusting a product title.

  3. 03

    Confirm USB PD on the adapter

    USB-IF says USB PD can reach 240 W, but actual power depends on all parts. Pick an adapter that meets the phone's requested level. Remember that a USB-C plug alone does not prove support for USB PD, USB 3.2 or USB4.

  4. 04

    Match the cable to the power level

    Use a cable rated for the USB PD level you expect. If the adapter and phone negotiate a level above the cable's rating, the system cannot deliver that level. Buy the cable for the power you need, not for the highest number available.

  5. 05

    Keep the wireless path clear

    Apple says cards, passports, security badges and key fobs must not sit between phone and charger. Also account for heat: Apple says heat may limit charging above 80%. Align the phone with the charger's magnetic profile if the phone supports it.

What this site is

An independent compatibility desk, not a charger store

Shop Fiora Charge Lab is a new technical reference published by the current owner of shopfiora.net. It does not take orders, rank sellers or represent a past business that used this domain.

Our method is narrow: check the standards body first, then check the phone maker. On 25 October 2026, this guide reviewed two WPC pages, two USB-IF documents and one Apple support page. It recorded the published limits shown here: Qi 2.2 up to 25 W, USB PD up to 240 W and Apple's up-to-25 W MagSafe guidance for compatible hardware. This was a document audit, not a lab speed test.

If a product label conflicts with the phone maker's current guide, use the phone maker's limit. If a Qi claim lacks a certified product listing, verify the model in the WPC database before buying.

Direct answers

Common compatibility questions

Do I need a Qi 2.2 charger to get 25 W?

Qi 2.2 added up to 25 W, but the phone must also accept that level. A Qi 2.2 charger cannot make a phone accept more than its own maximum. Check the phone documentation and the WPC certified-products database.

Does a USB-C plug guarantee USB PD?

No. USB-IF states that USB Type-C is a connector rather than a guarantee of USB PD, USB 3.2 or USB4. The adapter, cable and phone must all support the level you want.

Why does my phone charge slowly above 80%?

Apple says heat may limit charging above 80%. The phone's power limit can also slow charging. So can the wireless standard, adapter, cable or alignment.

Can I use a 240 W USB PD adapter with my phone?

USB PD can reach 240 W, but actual power depends on all components. A higher-rated adapter will provide what the phone requests, up to the phone's maximum. The phone will not take 240 W unless it is designed to request that level.

Can anything sit between the phone and wireless charger?

Apple says cards, passports, security badges and key fobs must not sit between phone and charger. Remove those items before charging. Cases or accessories may also affect alignment and charging.
