Anker Nano travel adapter review

This is a phone-and-earbuds adapter. If you need to run a laptop, skip down to the bit about the bigger Anker.

I haven't used it. Everything here comes from Anker's product page, read on Nov 2, 2026, so every wattage below is Anker's rating, not a measurement. I read no independent test of this model.

What you get

Anker's US store lists the Nano at $25.99 (checked November 2, 2026). The same page shows a 4.8 average from 410 customer reviews. Those are ratings on Anker's own store, which is a reason to read them lightly.

It has 2 USB-C ports, 2 USB-A ports and one AC outlet. It weighs 107 g. Anker says the plugs fold away and the adapter is small enough for a carry-on.

The charging, port by port

Max output is 20 W, and only the first USB-C port reaches it. Anker's spec table gives USB-C1 that full rating and USB-C2 less, 15 W. Use both and they share a total of 15 W, per Anker's notes. The USB-A ports top out at 12 W each and don't support Quick Charge 3.0, so Galaxy phones on USB-A charge at regular speed, says Anker.

That's fine for one phone. It isn't fine for a phone, a tablet and a watch charging overnight if you expect them all at speed. Anker's own FAQ admits that with every port in use "power-hungry devices might experience a slower charging speed".

The compatibility list on the page looks dated. It names iPhone 15 and Pixel 3a "and more", while the FAQ talks about the iPhone 16. I read that as a stale list.

The plugs, and the catch

The FAQ says the built-in plugs are Types A, C, G and I, and pairs them with A (US, Canada, Japan), C (Europe and many other countries), G (UK and some regions of Africa and Asia) and I (Australia, China). Anker says it is compatible with 146 countries. Against Wikipedia's table (checked Nov 2, 2026), each of those countries has a matching plug on the Nano: Japan lists A and B, and Germany lists C and F. See travel plug types by country for the full list.

Now the catch. The AC outlet, where your own charger goes in, takes Type A and C plugs with 4.0 mm round contacts. Anker's note says Type E and F plugs are not supported. If your laptop brick has a grounded European plug, it won't fit. A Type B US three-pin isn't on the list either, and Wikipedia says most Japanese sockets accept only Type A anyway.

It is not a voltage converter. Anker says it handles 100 to 240 V devices, with a 6 A limit on the AC outlet. If a device draws more, Anker says it may not charge or may charge intermittently.

On protection, the two Anker pages differ. The Nano's page lists short-circuit protection and temperature controls, with no surge rating to set against the Universal Charger's 320V overvoltage protection (ActiveShield 4.0).

Against the bigger Anker

The Anker Universal Charger is $79.99 (checked November 2, 2026) against the Nano's $25.99. It has 100 W total and 262 g, and Anker's port list is USB only, with no AC outlet, so it can't power a charger with its own plug. The Nano can, within its limits. Pick by what you carry.

Verdict

I'd score the Nano 7.5 out of 10. Nobody here has used it, so the score weighs price, the limits Anker states and how plainly the page reads. It does one thing well. A phone fast-charges from the main USB-C port, earbuds sit on the second, and on Anker's plug list you need no second adapter in the US, Japan, the UK or Australia. The grounded-plug restriction costs it points, and so does a spec sheet I can only read, not verify.

I'd buy it for a weekend carry-on. I'd skip it if my laptop charger has an E or F plug.

More options are in the best travel adapters, with the countries they miss, and the travel adapter catalog has both Ankers side by side. If you're packing a battery too, read power bank rules on planes first.
