It doesn’t take much online delving to find cheaper alternatives, with some online stores selling “Replacement Wireless Charging Box For AirPods” for as little as $15 outright.
Sounds like a bargain, right?
Probably not. Actually, in the case of that $15 set – the cheapest I could find at the time of writing – I’d go further and say definitely not, but even the sets selling for between $50-$100 are unlikely to be a great investment over the longer period too.
The first detail to recognise is that unlike, say, iPhone accessories where Apple has a whole “Made For iPhone” (MFi) third party accessories licensing program, there’s no equivalent for AirPods at all. The only official charging cases you can buy for any model of AirPods or AirPods Pro are those manufactured by Apple itself.
Then there’s the question of charging quality, with a number of online reports and reviews noting cheaper cases that either only work for a limited time before conking out themselves – almost certainly due to poor quality or limited batteries – or in some cases, actively killing the AirPods placed into them. That’s likely if their voltage regulation isn’t carefully managed – and doing so involves more expensive electronics that you’re not entirely likely to find in a $15 AirPods charging case!
The other issue with third party AirPods charging cases is that they’re not going to be compatible with the way that Apple manages firmware updates to AirPods and AirPods Pro. Firmware probably isn’t something that you think about with AirPods, because most of them are more in the bugfix/compatibility space rather than introducing new features – but that’s another feature you’ll only see with an official AirPods charging case.
