There are about a million different battery cases for Apple’s iPhone lineup, but none of them integrate with the handsets quite as well as Apple’s own Smart Battery Case. That great integration comes at a price, however — while third-party iPhone battery cases can cost as little as $20 or $25, Apple’s costs a whopping $99. If you want the best but you don’t want to pay quite that much, you’ll be happy to learn that the Apple iPhone 7 Smart Battery Case and the Apple iPhone 6/6s Smart Battery Case are both discounted right now on Amazon.

Here are the key details from the product page:

  • Charge your iPhone and battery case simultaneously for increased Talk time up to 25 hours, Internet use up to 18 hours on LTE, and even longer audio and video playback.
  • With the Smart battery case on, the intelligent battery status is displayed on the iPhone lock screen and in notification center, so you know exactly how much charge you have left.
  • The battery case supports Lightning accessories, such as the Lightning to USB cable (included with your iPhone) and works with the iPhone Lightning Dock (sold separately).
