Anker 621 MagGo Power Bank vs Anker Nano Power Bank 5,000mAh

Both are 5,000mAh Anker packs, but they solve different problems. The 621 MagGo snaps magnetically onto MagSafe iPhones and charges wirelessly at up to 12W, while the Nano plugs straight into a USB-C port and delivers up to 22.5W wired to nearly any device. The 621 MagGo is $42.99 at Walmart as of November 7, 2026; the Nano has no current new price listed, and its recent daily prices ranged from $29.99 to $44.99. Buy the MagGo for a cable-free iPhone top-up; buy the Nano for faster wired charging across iPhone, Android and iPad.

What reviewers say

Anker 621 MagGo Power Bank

  • 4.6 / 5296 ratings

Rated 4.6 out of 5 from 296 ratings, buyers mostly like the magnetic grip and slim size for everyday top-ups. The common gripes are the limited capacity and slower wireless speed compared with a cable.

What people mention
  • Magnet strengthPraisedOwners say the magnets hold the pack firmly to MagSafe iPhones, even in a pocket.
  • CapacityCriticisedBuyers note 5,000mAh only delivers about one partial charge, not a full day of power.
  • Charging speedMixed12W wireless is fine for topping up but slower than wired charging, and some say it feels slow.
  • Size and weightPraisedThe 0.45-inch body is slim enough to leave attached to the phone.

Anker Nano Power Bank 5,000mAh

  • 4.5 / 5208 ratings

Rated 4.5 out of 5 from 208 ratings. Owners like the cable-free design and the battery readout; the main complaint is capacity.

What people mention
  • ConveniencePraisedOwners value the built-in foldable USB-C plug because there is no cable to pack or lose.
  • Battery displayPraisedThe LCD percentage readout is called more useful than the usual four-LED indicators.
  • CapacityCriticisedReviewers say 5,000mAh delivers roughly one phone charge, so it suits top-ups rather than full days.
  • HeatMixed

Questions and answers

Which is better for a MagSafe iPhone?
The 621 MagGo. It attaches magnetically and charges wirelessly at up to 12W, so you can keep using the phone. The Nano needs the USB-C port, which is fine on iPhone 15 and later but not on iPhone 14 and older.
Which charges faster?
The Nano. It delivers up to 22.5W over its built-in USB-C connector, roughly double the 621 MagGo's 12W wireless output.
Which works with Android?
The Nano. Its USB-C connector covers Samsung and other USB-C phones. The 621 MagGo is built for MagSafe iPhones.
Is the 621 MagGo worth $42.99?
Only if cable-free MagSafe charging matters to you. It was $29.99 on October 31, 2026, so $42.99 at Walmart as of November 7 is near its recent high. The Nano has sold for as little as $29.99.
Do either charge a laptop?
No. Both are 5,000mAh phone packs. The Nano's 22.5W can top up a tablet slowly, but neither is a laptop power bank.
Which is easier to carry?
The 621 MagGo is thinner at 0.45 in and can stay stuck to the phone. The Nano is thicker at 1.02 in and 7.58 oz but has no loose cable.
