Anker 622 Magnetic Battery (MagGo): problems, parts and running costs

Checked: 2026-10-17

Summary

A 5,000mAh magnetic battery with a fold-out stand that clips onto MagSafe iPhones and charges them wirelessly at 7.5W. The recurring issue is heat, which can pause charging at 80% and leaves a real-world reserve of roughly 2,750-3,250mAh per fill. At $30 or less it is strong value; near its $47.99 list price a newer 15W Qi2 bank is the better buy.

Common problems and fixes

Heat during wireless charging — Anker says conversion losses warm the bank and phone and that an iPhone may pause or stop at 80% for temperature management; an r/MagSafe owner removed a 622 to cool. Fix: stop heavy use, remove a thick case and let both cool, then resume. [1][11]
Charging stops around 80% — usually thermal management rather than battery failure; if charging does not recover, follow Anker’s warranty troubleshooting. A genuine fault is covered by the 24-month MagGo warranty. [1][3][15]
7.5W wireless is half the speed of newer 15W Qi2 banks — heat narrows the gap in practice. Not a fault; it is the product’s rated ceiling. [1][5][13]
Abnormally short runtime with some third-party cables — an owner saw a 622 appear depleted after minutes on an aftermarket USB-C-Lightning cable, then recover after brief recharging, while the original Apple cable worked. Fix: check the cable and connection first. [12]
One output at a time — the bank can recharge itself over USB-C while wirelessly charging a phone, but it cannot run a wired device while wirelessly charging a second phone. [3][6]
Not recommended for the iPhone 12/13 mini — Anker cites fit and heat dissipation, and the bank overhangs these smaller phones. Choose a different bank for a mini. [4][6]

Parts and consumables

USB-C-to-USB-C charging cable (60cm) — one 60cm cable is included on Target’s Anker listing; a replacement is the Anker A8753 two-pack for $9.99 (Anker, October 2026). Replace only when lost or worn. [7][16]
USB-C 12W wall charger — not included; Anker recommends a 12W wall supply to refill the pack. [1][3]
MagSafe-compatible phone case — optional; Anker warns cases thicker than 2.5mm and nonmagnetic cases reduce efficiency. [1][2]

Yearly running cost

There is no subscription and no scheduled consumable; the bank needs an external USB-C charger. An illustrative estimate puts 200 full refills at about $1.20 a year at $0.20/kWh, assuming 0.030kWh drawn from the wall per refill, though actual wall use was not measured. [2]

When it is a good buy

Anker’s US store listed the 622 at $47.99 (October 2026), while Target color listings ran from $31.99 to $39.98 and Best Buy showed $47.99 for blue. At $30 or less new it is strong value; $31-$36 is reasonable for a discounted Target color; $37-$42 is conditional and the Anker 633 10K adds capacity and a stand for similar money; $43-$49 competes with the thinner, faster Anker Nano 5K Qi2 (A1665) at $54.99, which has no kickstand; $55 or more is a skip unless the folding stand is essential.
