What to know before buying

The advertised 45W is a maximum, not a guaranteed rate for every device. Charging speed depends on the device, its charging protocol and battery level. The manufacturer cites an iPhone 18 Pro reaching 50% in 15 minutes based on internal lab testing, with actual results varying.
The screen rotates 180° but not 90°, and automatically turns off after one minute of inactivity. Some devices charge without showing model or battery information. The manufacturer says such identification is limited to supported devices, and Lightning devices may not be detected or displayed.

Listing details to confirm

The listing states 240 Volts input and 5 Amps input, alongside 45 watts maximum output and 20 Volts at 5 Amps. These listed electrical details are inconsistent because the stated output voltage and current multiply to more than the listed maximum wattage. Confirm the intended ratings before purchase.

Customer feedback is favourable on charging quality and speed, and also mentions the display, compact size and value. Some customers report mixed experiences with functionality. For a 45W single-port charger, the positive speed feedback is relevant, but the mixed functionality reports mean buyers who depend on specific display behaviour should consider the stated device and screen limitations.

Customers appreciate the compact size, display features and value.

Mixed feedback

Feedback on functionality is mixed, with some customers describing strong performance and others reporting issues.

Frequently asked questions

Does the Anker Nano include a charging cable?

No. The product information says a charging cable is not included. A suitable USB-C cable is required.

Can this charger deliver 45W to every phone?

No. 45W is the listed maximum. The connected device and its charging protocol determine the rate, which may also decrease as the battery fills.

Is the display a touchscreen?

No. The screen is controlled with taps: one tap views status, a double tap changes modes, and a two-second press rotates the display 180°.

Will every compatible device show its model and battery level?

No. The listing limits those display features to supported devices. It says some devices still charge normally without showing model or battery information, and Lightning devices may not be detected.
