Wireless charging used to be available only on premium devices back in the day. This important feature has since trickled down to more affordable devices. However, it's still missing from entry-level phones, if you happen to own one of them, there's a neat trick to add wireless charging to your phone.
Devices like the Galaxy A12, Galaxy A13, Galaxy A21, Galaxy A02s, etc are some of Samsung's best-selling phones. Given that these are very affordable devices, it's understandable why the wireless charging feature is missing.
However if you buy this adapter from Amazon, available now for only $19.99, you can add wireless charging to any of your Samsung devices, as long as they have a USB-C port. Now you too can experience the convenience of wireless charging without having to spend a lot more money on a compatible device.
