Summary

A single-port 30 W GaN USB-C wall charger, model A2147, small enough for a pocket and aimed at phones and tablets. Check the job before you buy: one port and 30 W will not fast-charge a laptop or power a docked Nintendo Switch.

Strengths

  • Foldable US pins and a palm-size body make it easy to carry.
  • Two PPS windows plus a 20 V rail cover a wide range of phones.
  • Android Authority singled it out for value among 30 W chargers, with measured efficiency of 89.3%.
  • Anker customer service has sent replacements to owners whose charger failed.

Weaknesses

  • Only one USB-C port, so it cannot charge two devices at once.
  • 30 W will not fast-charge a laptop or drive a docked Nintendo Switch, whose dock wants 39 W.
  • Apple caps iPhone wired charging near 20 W, so the headroom mainly helps PPS Android devices.
  • No cable is included, so a 3 A USB-C cable is an extra cost.
  • A few owners report Nano-class chargers stopping after months to about a year.
  • The US warranty term is unstated, though other Anker storefronts list 24 months.

Full research notes and sources

Measured output and heat

A single bench test decoded all four fixed power profiles plus both PPS windows. It measured 29.5 W on the 15 V rail and 29.3 W on the 20 V rail, held about 29.6 W under PPS, and drove a Galaxy S24 to about 24.3 W under Samsung Super Fast Charging. Press testing charged a Galaxy Z Flip 4 from 0% to 100% in 80 minutes.

What 30 W will and will not charge

It is enough to top up a phone or tablet quickly but not to fast-charge a laptop beyond emergency MacBook Air use, and it cannot power a docked Nintendo Switch, whose dock wants 39 W.

Owner reports and warranty

Owner evidence is thin and mixed. Anker’s own troubleshooting lists not charging, intermittent charging and a hot unit among common Nano-family issues, and a few owners on Reddit describe chargers that stopped after months to about a year. Nobody has published a failure rate, so treat these as caution signals. Warranty is stated as 24 months on some first-party Anker storefronts, but the US product page only says Hassle-Free Warranty.

Is it worth it?

Anker lists the charger at $15.99 on its US store, and Android Authority lists a $22.99 MSRP. At $16 or less it is a strong single-port value; from about $20 the single port and 30 W ceiling start to hurt, because multi-port 45-67 W GaN chargers appear in the same band. Above the MSRP there is little reason to choose it over those.

Which model this is

This page covers the Anker 511 Charger (Nano 3, 30W), model A2147, the US foldable-plug version. Don’t confuse it with the Anker 711 Nano II 30W (A2146), which has no foldable US pins and no ActiveShield 2.0, or with the Zolo 30W (A2698), which lacks a 20 V profile. The Amazon listing is ASIN B0D8H5JJZT, a spec match for A2147 rather than a directly verified link.
