Earlier this month, Apple released a 14.3 software update for the HomePod and HomePod mini, and it has since been discovered that this update allows the HomePod mini to be powered by select 18W chargers.
As mentioned in a Reddit thread discovered by 8-bit, and confirmed by MacRumors, the HomePod mini now works with Apple’s own 18W USB-C power adapter and selects third-party 18W power adapters from brands such as Aukey. One user was even able to power the HomePod mini with an 18W battery pack from Cygnett, which enables portable use.
In the past, when you tried to use the HomePod mini with a power adapter rated below 20W, the speaker would simply display an orange light and not work. This may still be the case with some 18W power adapters, as some power profiles may be required.
Apple includes a 20W power adapter with the HomePod mini, but many customers may have an 18W power adapter from an iPhone 11 Pro or other device.
To check if HomePod mini is running software update 14.3, open the Home app on an iPhone, click the home icon in the upper left, click Home Settings, and click Software Update. UpdatesHomePod software updates are installed automatically, unless the feature is disabled, but updates can also be installed manually.
