Anker Laptop Power Bank 25K 165W: problems, parts and running costs

Checked: 2026-10-16

Summary

The main fault owners report is the built-in cable: the side lanyard cable can stop delivering power or crack at its solder, and a 2026 press case blamed a failed cable for damaging a MacBook Pro mainboard, with no recall for this model. Running costs are effectively zero beyond a 100W-or-higher USB-C charger, because there are no consumables and the cables are built in, but a failed cable cannot be repaired and the bank is glued shut. At $90-100 it is a strong buy for charging a laptop and one other device away from a wall; near or above $120 the slower self-recharge and the conditional 165W make higher-output rivals competitive.

Common problems and fixes

Built-in cable failure — owners report the side lanyard cable dropping to 0.1W after about a month, cracked solder at the mainboard, and a 2026 heise online case in which a failed cable was reported to have damaged a MacBook Pro mainboard; Anker said it was investigating but issued no recall for this model. Neither built-in cable is replaceable and the unit is glued shut, so the only fix is a warranty claim under the 18-month term. [2][5][6][7][8]
165W is conditional, not per-port — Anker’s own distribution table says 165W needs two devices and more than about 78% charge, and three or four devices share only 130W total; Best Batteries measured 57W to the priority port and about 7W each to the rest. Treat the extra ports as low-power convenience rather than equal outputs. [1][3][5]
Self-recharge is slower than advertised — the claimed 100W input measured 90W at Macworld and a 92W peak held about 22 minutes before a roughly 50W plateau at Best Batteries, giving a full recharge of about two hours. Use a 100W-or-higher charger and expect the plateau. [5][9]
Thermal throttling — Anker’s modes run 100W below 36°C, drop to 52W recharge and 65W discharge between 36°C and 38°C, and stop charging above 39°C; Best Batteries logged a 45.7°C surface after 30 minutes at 100W. Keep it out of the sun and avoid sustained 100W discharge without airflow. [4][5]
Heavy and thick — 595 g and 6.18 × 2.12 × 1.93 in, closer to a large food tin than a phone. Nothing to fix. [5]
The strap cable gets in the way — only one of the two cables retracts; the 30cm lanyard must be pushed back by hand and can come unhooked. Use the retractable 70cm cable for daily charging. [5][11]
No wireless charging — there is no MagSafe or Qi coil, only the USB-C and USB-A ports. [10]
Display flags cell health below 60% — the smart display warns when cell health falls under 60% of original capacity, and there is no user-serviceable battery. [5]

Parts and consumables

No replaceable parts or consumables reported. Neither built-in cable is user-replaceable and the unit is glued shut and not designed to be opened, so a failed cable or a worn retraction mechanism cannot be serviced, and no battery pack or cable is sold separately. [2][5]

Yearly running cost

Not enough data. There are no filters, pods or subscriptions, and the built-in cables mean no cable to buy, so the only yearly input is electricity for recharging; none of the sources gives a metered or computed figure for it, and the 100W-or-higher charger is a one-time purchase. [1][5]

When it is a good buy

$90-100: strong value for a laptop-first traveler who wants the built-in cables and accepts the cable-durability risk.
$101-120: fair; the convenience premium is real, but higher-output rivals become direct alternatives.
Above $120: weak-to-fair; buy only if the two always-attached cables are exactly what you want.

Store prices: Anker’s US store lists it at $119.99 and it launched at $99.99 at CES 2025; Best Buy showed $95.99 to $119.99 and CDW listed $119.99; in the UK the RRP is £89, with Expert Reviews finding it often near £66. [1][10]

The Anker Prime 26K (300W) and the Ugreen Nexode 25K (200W) are the alternatives to weigh: pick either when faster self-recharge (140W input) and higher total output matter more than built-in cables, though neither matches the two always-attached cables that are this model’s real differentiator. [5]
