This iPhone Air-exclusive MagSafe charger is Apple-certified, and users deem it a “total game-changer” for charging on the go.

Much like the iPhone Air, this MagSafe charger is slim, lightweight and fits compactly in your pocket — even when attached to your phone. The brand claims that it will “maximize battery life,” to choose the best times to recharge when it’s wireless connected to your phone. You can even double up on power by using a USB-C cord and attaching this MagSafe charger to your phone.

“OMG, just gotta update this after slapping it on my brand-new iPhone Air—it’s like they were made for each other, seriously,” says one reviewer. “[It] weighs next to nothing […], and paired with the Air’s super-slim 165g vibe? It’s like carrying air, lol—zero pocket sag, just pure convenience on the go.”

Another reviewer also addresses just how important that Apple-certified hardware really is: “One of the main reasons to buy this over some of the third-party options is the first-party integration in the software. This means that you have temperature control, you have an automatic stop limit at about 80% and there are a lot of smart features in there so that the battery pack knows when to prioritize charging your phone vs letting go for a little bit.”
