This guide was composed with AI assistance using primary documentation checked on 7 November 2026. It reports no hardware measurements.

A description of wireless charging does not by itself tell you which charger to buy. A more useful decision checks the entire combination: phone, charging pad, power adapter and operating conditions. AIINEWS proposes a verification workflow rather than treating the largest number on the packaging as an expected result.

What primary sources establish

• WPC records magnetic attachment and alignment in Qi 2.0, and support for up to 25 W in Qi 2.2. Specification capabilities are not confirmation that every product achieves them.
• WPC offers a certified-product database. Match the exact model, rather than relying on its brand alone.
• Apple says delivered MagSafe power depends on the iPhone model, adapter and system conditions, and documents temperature-related charging limits.

An AIINEWS decision workflow

Stage	Record	If uncertain
Phone →	Model and manufacturer guidance	Leave compatibility unconfirmed
Charging pad →	Exact model and certification lookup	Request the model identifier
Adapter →	Requirements in the pad manual	Avoid comparing advertised wattage
Conditions	Case, placement, temperature and workload	Check one variable at a time

This is a decision aid, not an efficiency measurement or a replacement for manufacturer safety instructions.

Plan the comparison before testing

Write down a repeatable procedure: use the same phone, starting battery range, background workload and observation period. Change one factor per trial. For example, keep the adapter constant when the chargers' instructions permit it. Record the conditions and repeat the comparison before interpreting the result.

A battery-percentage increase does not measure electricity drawn from the wall. An energy-cost comparison needs suitable input-side measurement. If you record only the battery display, describe the result as an observed charge-rate comparison under stated conditions. Do not infer electrical efficiency or battery longevity from one charging session.

Limits and disclosure

AIINEWS has not performed hardware measurements for this article. It does not rank brands or report charging-time or energy-saving results. The table is an independently composed verification method. Any later test should identify the hardware, instruments, conditions, repetitions and underlying data.
