Compact 20W USB-C charger

The Anker 511 Nano Pro delivers 20 watts of power over a single USB-C port. It is built for owners of recent iPhone models from the 12 series through the 16 series who want faster charging than a legacy 5W adapter provides. The unit also supports compatible Galaxy and Pixel handsets. Its lightweight plastic body and foldable two-pin North American plug make it suit travel or a permanent desk spot.

Thermals and power draw

ActiveShield technology monitors temperature dynamically while a Power Tuner chip adjusts output to protect the connected device. The charger accepts 100-volt input and provides 5-volt or 9-volt output at up to 15 amps. In normal use it runs quietly with no moving parts and draws only the power required by the attached phone or tablet.

Build and daily use

The enclosure is moulded plastic weighing 0.07 pounds and finished in Arctic White. A single USB-C port means one device charges at a time, so users with multiple gadgets will need a second charger or a multi-port hub. The foldable prongs reduce bulk in a bag, and the package includes the charger and a welcome guide; a charging cable is not supplied.

Questions about this item

How do I install the Anker 511 Nano Pro 20W charger and what step do people often miss?

Plug the 2-pin Type A plug into a 100 V wall outlet, then connect a USB-C cable to the single USB-C port; the step people miss is supplying their own cable because none is included.

What maintenance or replacement will the Anker 511 Nano Pro 20W charger need later?

No routine maintenance is required; if the unit fails within 18 months the warranty covers replacement, otherwise the whole charger is replaced.

What limit appears first on the Anker 511 Nano Pro 20W charger during sustained use?

The ActiveShield system monitors temperature and the Power Tuner Chip reduces output to protect connected devices, so thermal throttling is the first limit.
