Original Anker 521 Nano Pro 40W Dual USB-C Fast Charger – UK 3-Pin

Description

Original Anker 40W Charger – 521 Nano Pro Dual USB-C Fast Charger (A2038)

The original Anker 40W charger (Anker 521 Charger, Nano Pro) fast charges two devices at once through two USB-C ports. Plug in one device and it gets the full 40W; plug in two and each port delivers 20W, so you can fast charge your phone and your iPad, AirPods or Apple Watch together from a single wall socket.

It is smaller than two standard 20W chargers combined, supports PowerIQ 3.0, USB-C Power Delivery and PPS for iPhone, Samsung Galaxy, Google Pixel and other USB-C phones, and is protected by Anker’s ActiveShield temperature monitoring.

Frequently Asked Questions

Is this an original Anker charger?
Yes. This is the original Anker 521 Charger (Nano Pro), model A2038K21, with the UK 3-pin plug.

Is the Anker 40W charger good for iPhone?
Yes. Both ports support USB-C Power Delivery, so it fast charges iPhone 8 and newer. An iPhone 13 goes from 0 to 50% in about 30 minutes.

Is it good for iPhone 17 Pro Max and iPhone 18 Pro Max?
Yes. Both phones charge over USB-C Power Delivery, so it fast charges the iPhone 17 Pro Max and iPhone 18 Pro Max with the USB-C cable that came in the iPhone box, and the second port can charge your AirPods or Apple Watch at the same time. For the iPhone 18 Pro Max’s very fastest charging speed, Apple recommends a 60W adapter.

Can it charge two phones at the same time?
Yes. With both ports in use, each port delivers 20W, which is fast charging speed for most phones.

Does it fast charge Samsung phones?
Yes. It supports PPS, the fast charging standard used by Samsung Galaxy phones, and gives Galaxy phones Samsung Super Fast Charging (25W) from a single port. The Galaxy S25 Ultra, S26 Ultra and Z Fold 8 can also charge faster (45W to 60W), but that needs a 45W or higher PPS charger with a 5A cable.

Can it charge a laptop?
Yes. A single port gives up to 40W, enough to charge a MacBook Air and many small USB-C laptops.

Is a cable included?
No. The box includes the charger only. Use a USB-C to USB-C cable, or USB-C to Lightning for older iPhones. You can add one from our charging cables range.
