AUNNO UK to US Plug Adaptor (Type B) with 20W Charging and 4 USB Ports
Product description
If you’re travelling from the UK and want one compact charger that covers both plug conversion and everyday power needs, this AUNNO UK to US Plug Adaptor is worth a look. It’s built around a grounded USA-style Type B socket, plus multiple USB ports for phones, tablets and small personal devices.
That said, it’s not a magic adapter for every scenario—especially if you’re relying on high-watt appliances or travelling with equipment that needs a very specific power setup. So it helps to sanity-check your device power needs before you pack.
The essentials
This is a 5 in 1 UK-to-US travel adapter approach: it provides a Type B AC socket (UK 3-pin input) and combines it with USB charging in one unit. On the charging side, you get both USB-A and USB-C. The Type C port is specified at 5V/3A, while the USB-A ports are specified at 5V/2.4A on the USB charging port, with a stated maximum power of 20W for the adapter charging capability.
In real terms, it’s the kind of travel hub that can top up a smartphone and a tablet at the same time, and still give you an AC outlet for a shaver, camera charger or other smaller mains device.
What’s good about it in daily use
The strongest practical benefit here is convenience. Instead of hunting for separate plug converters and chargers, you’re using one piece of kit. On a typical trip, you might plug in a phone via USB-C, run a second device off USB-A, and use the AC socket for something that doesn’t charge over USB.
It also has a compact design that’s described as smaller than the palm of your hand and under 120 grams. If you travel light (carry-on, weekend breaks, frequent hotel stays), that portability matters more than it sounds.
Key points on charging and limitations to note
A stated maximum power of 20W and separate port ratings are useful, but they also hint at the right expectations. If you’re planning to run power-hungry appliances (things like high-watt hairdryers or similar), you can’t assume every trip outcome will be the same—depends heavily on the appliance wattage and how it behaves with the adapter.
There’s also a wider “adapter headroom” claim in the base description (a maximum power figure is mentioned). Still, for purchase decision-making, treat the adapter as a travel charging + small device helper, not something you’d lean on for continuous heavy loads.
Safety and build: where you’ll feel more confident
This adapter is positioned as safety-first. It uses PC fire-retardant material, includes a 10A fuse inside, and is designed with protections described for overload, over-current, over-voltage, short-circuit and over-heat. There’s also a child-safe shutter mentioned.
It’s not just theoretical either: the housing is described as 750°C flame-retardant and intended to resist high temperatures, which is the sort of detail you want when you’re packing something you’ll plug and unplug repeatedly.
If you’re someone who hates flimsy adapters that get warm quickly, the protection list and flame-retardant framing are the bits to focus on.
Compatibility: the countries it’s aimed at (and where you should double-check)
The base description lists suitability for places including the USA, Canada, Mexico, Thailand and several others. It’s specifically described as a UK to US travel adapter with a Type B setup.
That “Type B” point is important. Out in the wild, not every country uses the same plug standard. Even within regions, standards can differ—so it’s sensible to verify your destination plug type before you rely on this for everything.

Who it suits best (and who may want to skip it)
It makes sense if you want one compact travel adaptor that covers both an AC socket and multi-port USB charging—especially for phones, tablets, small chargers and personal grooming items.
It might not be a great match if you’re expecting to power large, power-hungry appliances for long periods, or if your devices require a very specific power arrangement beyond what a standard travel adapter is designed to handle. It’s also worth bearing in mind that maximums are not the same as real-world usage—so if you’re unsure about your appliance wattage, don’t assume compatibility.
Mini FAQ
How many charging ports does it include?
It includes 2 USB-C ports and 2 USB-A ports, plus 1 AC socket.
What’s the USB-C charging rating?
The USB-C port is specified as 5V/3A.
Is it grounded for US-style plugs?
The adapter is described as a grounded USA adapter with a Type B setup.
Can I use it for hairdryers and shavers?
The base description lists cameras, tablets, shavers, hairdryers and other devices as typical travel use cases—but the real outcome depends on the appliance’s power draw.
Should you buy it?
Buy it if you want a single, pocket-friendly UK to US Type B adaptor with multiple USB ports so you can charge several devices at once and still have an AC socket for smaller mains gear. It’s also a good fit if safety protections and a flame-retardant build are high on your checklist.
Skip it if you’re mainly travelling with high-watt appliances and expect the adapter to do heavy-duty powering. Also, if you haven’t checked that your destination uses a Type B plug standard, it’s better to verify first—otherwise you could end up with the wrong setup for your trip.
