Compact: the essentials for travel or a light setup.

Why people pick it

  • At 8.6 mm and 122 g it's about as thin and light as magnetic packs get
  • Qi2-certified 15W magnetic charging lines up reliably on MagSafe iPhones
  • 20W USB-C works in both directions, so it can also charge earbuds or a second phone by cable

Know before you buy

  • 5,000mAh is a top-up, not a full recharge for large phones
  • Wireless tops out at 15W, not the 25W of newer Qi2.2 packs
  • Charging two devices at once drops to slow 5W-class rates
  • Phones without built-in magnets (including many Android models) need a magnetic case
