Designed to slip into your pocket, it feels great in your hand and adds up to 65 percent additional charge to iPhone Air — extending battery life further than the battery life of any other iPhone. Attach the MagSafe Battery to your fully charged iPhone Air for all-day use. To maximize battery life, the combined system will choose the best times to recharge. Or when you need a quick boost, just snap it on for up to 12W of fast wireless charging on the go. For even faster charging of your iPhone Air, attach the MagSafe Battery and connect it to a 20W or higher power adapter at the same time.

The Quick-Release Battery Pack allows you to have backup power for select battery powered Ring Doorbells and Cameras. To charge your battery pack, simply connect it to a micro-USB cord and plug it into a power outlet. If the battery pack in compatible Ring Video Doorbell or Securtiy Cam runs out of power, you can remove your batteries by pressing the quick-release tab on the battery pack. Then, simply slide your second battery pack into your device, and you’re good to go.
