As you can tell from the photo above, this is a charging mat that is capable of charging multiple wireless charging devices at the same time. On the mat itself, it appears that there is space for at least three devices like smartphones or wireless earbuds (assuming their cases support wireless charging).
Then there is also the addition of a charging stand designed for the Apple Watch in mind, so for non-Apple Watch users, this might not be quite as useful. However, if you don’t own an Apple Watch, you can remove the Apple Watch charger and use its USB-A port to plug in a regular charging cable that you can use to charge other devices through a wired connection.
The Mophie 4-in-1 Wireless Charging Mat isn’t exactly cheap at $150, but if you’re looking for an elegant wireless charging solution that you can take with you on your travels so that you don’t have to deal with multiple plugs or cables, then this could be worth checking out.
