Anker 621 Magnetic Power Bank: Slim 5,000mAh Travel Charger

The Anker 621 magnetic power bank combines a 5,000mAh battery with magnetic wireless charging in a compact design that’s easy to slip into a pocket or travel bag. The Anker 621 Magnetic Portable Charger (MagGo) is designed primarily for MagSafe-compatible iPhones and gives you an easy way to add backup phone power without carrying a large battery pack.

For cruises, it can be particularly useful on shore excursions and long days away from your cabin when you’re using your phone for photos, maps, cruise apps, messaging and transportation.

A Slim 5,000mAh Magnetic Power Bank

The Anker 621 is just 4.13 x 2.62 x 0.45 inches, giving you a relatively thin power bank that can remain attached to a MagSafe-compatible iPhone while you continue using it.

Instead of connecting a cable every time you need some extra power, the magnetic surface aligns with compatible MagSafe iPhones and magnetic cases for wireless charging.

Key features include:

  • 5,000mAh battery capacity
  • Up to 7.5W magnetic wireless charging
  • USB-C input and output for recharging the power bank or providing a wired charge
  • Up to 12W USB-C output
  • 4.13 x 2.62 x 0.45-inch dimensions
  • Compact design that’s easy to carry in a pocket, purse, backpack or day bag
  • USB-C to USB-C cable included
  • Anker’s 24-month warranty

Why a Power Bank Makes Sense for Cruises

A cruise can mean spending much more time than usual using your phone away from a charger. You may be taking photos around the ship, checking the cruise line app, messaging other passengers, navigating a port with Google Maps or arranging transportation during an excursion.

A small magnetic power bank works especially well for this kind of use because you don’t have to carry a large battery or have a charging cable dangling between your phone and a power bank.

It can also help you make better use of the limited number of outlets in many cruise ship cabins. You can charge the Anker 621 when an outlet is available, then use the power bank later to charge your phone without tying up one of the cabin’s outlets.

The 5,000mAh capacity also strikes a useful balance for travel. It’s designed more as a compact source of additional phone power than a large battery bank intended to recharge several devices repeatedly.

Magnetic or Wired Charging

Although magnetic charging is the standout feature, the USB-C port gives the Anker 621 additional flexibility. You can use that port to recharge the power bank or connect a compatible device for wired charging.

That means the battery isn’t limited exclusively to magnetic charging, which can be useful when traveling with other USB-C devices.

Keep in mind that magnetic charging works best with a MagSafe-compatible iPhone without a case or with a magnetic/MagSafe-compatible case. Thick non-magnetic cases and accessories attached between the phone and charger can interfere with the magnetic connection and wireless charging.

Flying to Your Cruise? Keep Power Banks in Your Carry-On

If you’re flying to your cruise port, portable power banks containing lithium-ion batteries need to travel in your carry-on baggage rather than checked luggage. If your carry-on is checked at the gate, remove the power bank and keep it with you in the aircraft cabin.

Bottom Line

The Anker 621 Magnetic Power Bank is a strong travel option for MagSafe-compatible iPhone users who want convenient backup power without carrying a bulky battery pack. Its slim magnetic design makes it especially handy for shore excursions, travel days and other times when you want to keep using your phone while it charges.
