Who Should Buy This#

The Anker 621 MagGo fills a gap that traditional power banks leave wide open: the need for quick, cable-free top-ups without bulk. It delivers magnetic convenience and pocket-friendly portability that chunky battery packs simply cannot match.

Perfect for:

  • Daily commuters who need a quick charge boost during the train ride home without fumbling with cables
  • Weekend travelers who want backup power that fits in a jacket pocket without weighing them down
  • Remote workers at cafes who need to extend their iPhone through a full work session away from outlets
  • Festival and event goers who want hands-free charging while walking, snapping photos, or navigating crowds

Design & Build Quality#

The Anker 621 MagGo is remarkably thin and light. At just 0.5 inches thick and 4.8 ounces, it practically disappears when attached to the back of your iPhone. The rounded edges and smooth matte finish feel premium without being slippery.

The magnetic alignment ring locks onto MagSafe-compatible iPhones with a satisfying snap. The connection is strong enough to stay attached during normal use but easy to remove when you need your phone bare. A small LED indicator on the side shows remaining charge at a glance, and the single USB-C port handles both input charging and pass-through power delivery.


Key Features#

Magnetic Snap-On Charging#

The built-in magnet array aligns perfectly with iPhone 12 and later MagSafe rings. You do not need to line up a cable or even think about positioning. Just bring the power bank close to your phone and it locks into place. The 7.5W wireless output is not the fastest charging method available, but it is perfectly adequate for passive background charging while you use your phone normally.

5,000mAh Capacity#

With 5,000mAh of stored energy, the MagGo delivers roughly 0.75 full charges to an iPhone 15 or about 0.6 charges to an iPhone 15 Pro Max. That translates to several extra hours of active use, enough to get through a long afternoon or evening without anxiety. For most people, this is the difference between a dead phone at dinner and making it home comfortably.

Ultra-Portable Form Factor#

At 3.8 x 2.5 x 0.5 inches and under 5 ounces, this is one of the most pocketable power banks on the market. Unlike brick-shaped battery packs that need their own bag pocket, the MagGo slides into jeans, jacket pockets, or small crossbody bags without creating a bulge. You genuinely forget you are carrying it.

USB-C Recharging#

The power bank recharges via USB-C in about 2.5 hours. You can also use the USB-C port for wired charging output, giving you the option to charge non-MagSafe devices in a pinch. The inclusion of a USB-C cable in the box means you are ready to go straight out of the package.
