among many robots TVs, electric vehicles, and hair printers At CES, there was an announcement of the next generation of wireless charging for phones and other devices with rechargeable batteries. Qi2 Pronounced “chee two,” it is a follow-up to the Qi wireless charging found in phones like the iPhone 14 Ultra introduced by the company. Camel And Samsung Galaxy S22 andThe Google Pixel 7.
According to the American (cnet) website, the next version of Qi promises to be more efficient in part because of magnets that help put devices in perfect alignment on charging pads.
If this sounds familiar, he continued, that’s because Apple’s MagSafe charging, which was introduced with the iPhone 12 in 2020, is basically the same, and Apple, one of more than 350 companies that make up the Wireless Power Consortium, also helped design a profile. Magnetic Energy which is part of Qi2.
The site added that although the magnetic energy profile does not exactly match MagSafe, it could lead to Qi2 being adopted on more devices, including AR or VR headsets, and could also lead to faster charging speeds. Qi wireless charging caps off at 15W, which is also Apple’s MagSafe charging speed limit on iPhones.
iPhone 12 and 12 Pro accessories and MagSafe
Apple’s MagSafe uses Qi wireless charging, but the magnet allows for a variety of attachments.
“Qi2’s perfect alignment improves energy efficiency by reducing power loss that can occur when a phone or charger is not aligned,” Paul Strohsaker, executive director of the Wireless Power Association, said in a press release.
“Equally important, Qi2 will significantly reduce the landfill waste associated with wired charger replacement due to broken plugs and the stress placed on wires from everyday plugging and unplugging.”
And the site confirmed that given that Android phones come in all shapes and sizes, Qi2 and its magnetic energy profile can be equalizers that make some accessories interchangeable between different phones and even different devices, and Qi2 provides a level of presence everywhere similar to that provided by USB connectors. -C, without the confusion caused by different types of USB-C cables all looking the same, and it’s hard to tell the difference between a USB-C cable that supports Thunderbolt 3 and one that supports USB 4.
Qi2’s magnetic energy profile is different from MagSafe, which also uses magnets but is arranged in a different position, so the MagSafe charger cannot be attached to a Qi2-enabled phone.
