Anker 511 Charger (Nano 3, 30W): problems, parts and running costs

Checked: 2026-10-17

Summary

The Anker 511 Charger (Nano 3, 30W), model A2147, is a single-port 30 W GaN wall charger, and the things that usually go wrong are an outright stop after months to about a year and a US warranty term that the product page never states. There are no replaceable parts and the only extra cost is a USB-C cable that is not in the box. At about $16 it is a strong single-port value and above about $25 it is weak.

Common problems and fixes

Charger stops charging entirely — individual owner reports describe Nano-class chargers that worked for almost a year and then stopped; the fix is to try another cable, outlet and device, and the 24-month warranty on some first-party storefronts may cover a replacement. [10][11][13][17]
Intermittent or random stop after about a month — one owner reported a charger that randomly stopped charging after roughly a month; Anker’s own troubleshooting lists not charging and intermittent charging among common Nano-family issues. [11][13]
One port only — it cannot charge two devices at once; the fix is a multi-port charger, since nothing is split on a single port. [1][2]
30 W will not fast-charge a laptop or run a docked Switch — the dock wants 39 W, so this charger only covers emergency MacBook Air-class top-ups; buyers who need that should buy a higher-wattage multiport unit. [4]
No cable included — a 3 A-capable USB-C cable is an extra cost. [4][6]
US warranty term is unstated — the US product page says only “Hassle-Free Warranty” while other Anker storefronts list 24 months; the exact US term is not confirmed. [1][3][17]

Parts and consumables

No replaceable parts or consumables reported. Anker documents no user-serviceable parts for this model and its guidance is limited to reset steps and trying another cable, outlet or device. [13][14]

Yearly running cost

Not enough data. The only recurring cost is a USB-C cable, which is not included, and the sources give no cable price or annual figure. [4][6]

When it is a good buy

Anker’s US store lists it at $15.99 (2026-10), Android Authority lists a $22.99 MSRP, TechRadar lists $18.99 and Anker Canada lists CA$24.99. At $16 or less it is strong value for one compact 30 W phone and tablet charger; from $20 the single port and 30 W ceiling start to hurt, and above about $25 there is little reason to choose it. [1][5][7][17]

Multi-port 45–67 W GaN chargers — the better choice when you need two or more devices or laptop fast-charge from one brick. [4][5][7]
