Compatibility planning

How do you match one wireless charger, one USB-C adapter and one cable to your phone?

Build the kit from the phone outward: confirm the wireless standard, confirm USB PD support, and remove items that block wireless charging. Qi 2.2 added up to 25 W; USB PD can reach 240 W; actual power depends on all components.

01

Build from the phone outward

The phone is the first limit. Find its accepted wireless charging level and its accepted USB PD level in the phone manufacturer's documentation. Every other purchase should be sized to those numbers, not to the largest numbers available.

Apple currently says compatible iPhones can reach up to 25 W with compatible MagSafe hardware and a 30 W-or-greater adapter. Actual power varies with model and conditions. That example shows why the phone model and the hardware compatibility both matter.

For non-Apple phones, use the phone documentation for the same two numbers: wireless level and wired USB PD level. If the documentation does not state them, use a lower-risk kit rather than paying for a higher specification the phone may not accept.

02

Match the wireless side

Choose a wireless charger whose specification matches the phone. Qi 2.2 added up to 25 W, and Qi 2.0 introduced the Magnetic Power Profile. If the phone supports magnetic alignment, a charger with that profile can position it correctly. If not, standard Qi alignment is enough.

Check the charger model in the WPC certified-products database. That step confirms the specification listing behind the product name and helps you avoid paying for a profile the phone cannot use.

For a MagSafe-compatible iPhone, pair the charger with a 30 W-or-greater adapter to aim for the stated up-to-25 W range. For other phones, follow the charger's input requirement and the phone's accepted level.

03

Match the wired side and avoid bottlenecks

For USB-C charging, USB PD can reach 240 W, but actual power depends on all components. Match the adapter and cable to the phone's accepted USB PD level. A higher rating can leave capacity the phone does not use, so confirm compatibility in the device and accessory documentation.

USB Type-C is a connector rather than a guarantee of USB PD, USB 3.2 or USB4. Verify USB PD support on both the adapter and the cable. If the cable is rated below the adapter and phone level, it becomes the limiting part.

Keep the wireless path clear. Apple says cards, passports, security badges and key fobs must not sit between phone and charger. Also remember that heat may limit charging above 80%.

Ordered check

Assemble the kit in five checks

  1. 01

    Record the phone's wireless and wired maximums

    Write down the accepted wireless level and the accepted USB PD level from the phone documentation. These are the two numbers the rest of the kit must serve.

  2. 02

    Pick the wireless charger by specification

    Match Qi 2.0 Magnetic Power Profile or Qi 2.2 up to 25 W only if the phone supports it. Check the model in the WPC certified-products database.

  3. 03

    Pick the adapter for the wireless charger or wired phone

    For Apple's up-to-25 W statement, use a 30 W-or-greater adapter. Otherwise, meet the charger's input requirement and the phone's USB PD request.

  4. 04

    Pick a cable rated for the power level

    Confirm USB PD support and a power rating at or above the level you expect. USB Type-C alone does not guarantee USB PD, USB 3.2 or USB4.

  5. 05

    Prepare the charging surface

    Remove cards, passports, security badges and key fobs from between phone and charger. Keep heat in mind above 80%.
