Magnetic wireless chargers used to come in two kinds: proprietary ones and generic pads that charged slowly. The Wireless Power Consortium's (WPC) Qi2 standard changed that, and its newer Qi2 25W profile raises the speed further. Here is what the standard actually specifies, based on WPC's own documentation.

From Qi2 to Qi2 25W

  • Qi2 (2023): Qi version 2.0, published in April 2023, introduced the Magnetic Power Profile, which uses magnets to align the phone and charger. According to WPC, Qi2 launched in November 2023 with 15 watts of charging power.
  • Qi2 25W (2025): WPC brands Qi version 2.2.1 as Qi2 25W and says it launched in July 2025. Version 2.2 added support for up to 25 watts, power modes tuned to the USB-C adapter feeding the charger, and extra checks for foreign objects such as coins or keys before charging at higher power.

How much faster?

WPC says Qi2 25W delivers "nearly 70% more charging power" than the original Qi2 and can charge a smartphone battery from 0 to 50% in about 30 minutes. These are the standards body's own figures, not independent measurements, and real speed depends on the phone, the charger, temperature and the power adapter. A 25W charger can only deliver its top speed to a phone that supports Qi2 25W, and only when powered by an adapter that can supply enough wattage.

What to check before buying

  1. Certification: WPC says only Qi Certified products, tested at an authorized lab, may show the Qi or Qi2 logo. Look for the certified logo rather than vague "magnetic" or "Qi2-compatible" wording.
  2. Your phone's support: check whether your phone is listed as supporting Qi2 or Qi2 25W. Older phones will usually charge more slowly.
  3. The power adapter: buy or reuse a USB-C adapter with enough wattage for the charger's stated input.

A note on version numbers

WPC's own pages differ on which specification version is newest; its download page mentions a members-only v2.3. For shoppers, the certified product name (Qi2 or Qi2 25W) matters more than the version number.
