If Apple’s super-thin iPhone Air has one drawback, it’s the battery life. Apple understands this, which is why it makes a MagSafe battery pack that fits perfectly under the iPhone Air’s camera bump. Normally $99, it’s on sale for 20 percent off at Amazon right now, the first time we’ve ever seen it this low.

Like the phone itself, the iPhone Air MagSafe Battery ​​​​​​​ is super slim and stylish, and won’t add too much bulk to the back of the phone. It’s designed to slip into your pocket with ease and has enough power to add up to 65 percent of your phone’s battery life, giving you those extra hours you absolutely need before you get to your regular charger. Just attach it, forget about it, and you’ll get through a full day without needing to think about a charger.

If you wait till you need a charge, it delivers 12W of fast wireless charging, so it won’t take long before your phone is back to 100 percent. And sure, you may find similar power banks for less out there, but there’s none that will fit as well as this one does on your iPhone Air.

So take advantage of this rare 20 percent discount for the Apple MagSafe power bank for the iPhone Air before it vanishes into thin air.
