Qi2 is a wireless charging specification released by the Wireless Power Consortium in 2023. It builds on the original Qi standard by adding a magnetic positioning system that automatically aligns your phone with the charger's power coils. This alignment improves charging efficiency and reduces the time needed to transfer energy.
The magnetic alignment system works through a series of magnets embedded in both the phone and the charger. When you place your phone on a Qi2 charger, these magnets pull the device into the optimal position without any manual adjustment. This contrasts with older Qi chargers, which required you to find the right spot yourself to achieve reliable charging.
Why it matters: Qi2 chargers deliver more consistent power transfer, typically reaching up to 15W for compatible phones. The magnetic system also enables faster charging speeds because the coils maintain perfect alignment throughout the charging cycle. Manufacturers have begun embedding Qi2 magnets into flagship phones, making wireless charging more practical for everyday use.
Key differences from older Qi: The original Qi standard offered charging up to 5W, and later versions reached 7.5W or 10W depending on the device. Qi2 standardises the magnetic positioning, eliminating the guesswork. However, Qi2 chargers remain backward compatible with older Qi devices, though they won't benefit from the speed improvements.
What you should know: Not all phones support Qi2 yet. You'll need a device with built-in Qi2 magnets or a magnetic phone case to use a Qi2 charger effectively. Apple's iPhone 12 and later models support the standard, as do many Android flagship devices. Qi2 chargers are becoming more affordable, but they still cost more than basic Qi alternatives.
