Apple's MagSafe Battery Pack is on sale for 19% off

Save $19: Charge on the go. Snag an Apple MagSafe Battery Pack at Amazon for just $79.93, down from $99.99, and save $19.07 as of Oct. 29.

Charge your iPhone easily with Apple's MagSafe Battery Pack, which snaps onto your phone via magnet for on-the-go charging.

This external battery, which Apple released in July, basically functions as a battery-charger combo. It's compatible with the iPhone 13 Pro Max, iPhone 13 Pro, iPhone 13, iPhone 13 mini, iPhone 12 Pro Max, iPhone 12 Pro, iPhone 12, and iPhone 12 mini.

The perks: It's super lightweight and portable, charges automatically, and lets you track your charge on your phone's lock screen. The cons: As The Verge reports, it's really best if you want to "top up your iPhone, not fully charge it" — especially if you have a larger phone.

If you want to charge your phone and the battery pack at the same time, you'll need a 15W USB-C power adapter and Lightning cable, according to Apple. (However, the adapter and cable are sold separately. Thanks, Apple!)

Still, if you want a reliable, portable battery pack made by Apple, check out the MagSafe Battery Pack for $79.93 at Amazon.
