Wireless Charging That Doesn’t Suck - Qi 2

Wireless charging has long promised convenience but often delivered slow speeds, awkward alignment, and heat that affected battery longevity. This video introduces Qi 2, the next generation of wireless charging, highlighting its magnetic design that helps devices magnetically latch onto the charger and aligns with the phone’s induction coil for more reliable charging. It explains that Qi 2, with input from Apple and other major players, aims to reduce heat buildup by bringing the coils closer together and better aligned, which should translate to less wasted energy and more efficient charging. The host notes that although Qi 2 starts with upper limits around 15 watts, the standard is designed to support higher charging rates in the future and will feature a handshaking process that can warn or deter use of non-compliant chargers. They also discuss practical implications, such as more consistent charging without constant readjustment, and the likelihood of early Qi 2 devices arriving later in 2023 with phones and earbuds, followed by tablets and smartwatches in 2024. The video also touches on compatibility and ecosystem effects, including Apple’s involvement in the Wireless Power Consortium and the possibility of delisting non‑compliant chargers from major retailers. Overall, Qi 2 is presented as a more forgiving, faster, and safer wireless charging standard that could address long-standing frustrations with the original Qi and MagSafe equivalents.
