EINNO UK to US Plug Adaptor 3-in-1 with USB-C & USB-A (Type B) for US, Canada, Mexico and more
Product description
What it is and when you’ll want it
This EINNO UK to US plug adaptor is designed for trips where your UK plug needs to work in countries that use a US-style wall socket (Type B). Instead of just changing the plug shape, the adaptor also builds in two USB charge points: one USB-C and one USB-A. That means you can power multiple small devices from a single wall socket when you’re travelling with a phone, earbuds, a tablet, or similar gear.
On paper, it’s a practical “one thing to pack” solution: swap the plug for the country you’re visiting, then use the USB outputs to top up devices without hunting for extra chargers. The compact size is clearly aimed at travel days—grab it and go—rather than leaving a bulky multi-adaptor at home.
Key takeaways (the decision in plain English)
If you mainly need plug compatibility for US-style sockets and you also want straightforward charging via USB, this adaptor makes sense. It’s not trying to be a universal voltage transformer, and it doesn’t claim to handle high-power appliances.
It’s the kind of gadget that earns its keep when you’re sharing one wall outlet in a hotel room, charging on the go in the office, or simply want less cable clutter. Just keep expectations realistic: it’s a travel plug adaptor with USB charging, not a full power solution for everything.
Where it stands out for everyday travel
The stand-out feature is the 3-in-1 setup: it converts a UK plug into a usable US Type B outlet while also offering USB-C and USB-A charging. In a typical scenario, you could plug in one device through the adaptor’s US outlet (for example, a small charger with its own plug), then charge two additional devices via the built-in USB ports—without needing a separate multi-USB charger.
There’s also a clear “safety first” approach described here. The adaptor is built with a fire-resistant shell, and the Type B plug includes a round grounding pin for secure fit and grounding. For many travellers, those details matter as much as the plug shape itself, especially when you’re constantly swapping devices in and out.
Portability is another plus. At 9.2 x 5.6 x 3.5 cm and 91 g, it’s easy to slip into a travel bag without it becoming dead weight.
What to watch before you buy (important limitations)
The biggest limitation is voltage: this adaptor does not convert voltage. That’s a non-negotiable point. If you’re travelling to a country with different voltage from what your device supports, you must check that your device supports 100–250V. For anything high-power (think hair tools, kettles, and similar), you’ll likely need a voltage converter alongside this adaptor.
A second thing to bear in mind is power output. The USB outputs are rated at 12 W max. That’s generally suitable for phones, tablets, and other small electronics, but it can feel restrictive if you’re trying to run something that needs more demanding charging. If you routinely travel with power-hungry devices or you expect laptop-style charging, you may find this sits more in the “small device charging” bracket than “everything charging.”
Worth noting too: the description lists compatibility in multiple destinations, including the USA, Canada, Mexico, Colombia, the Philippines, and parts of Thailand. It’s not an all-countries guarantee, so it’s still worth checking the plug type used where you’re going.

Pros and cons to help with “is it worth it?”
What you’ll like - 3-in-1 design: Type B plug + USB-C + USB-A from a single socket - Clear travel focus: compact size and light weight - Safety-oriented design details, including grounding pin and fire-resistant shell - USB charging for smaller devices without extra adapters taking up space
Where it may fall short - No voltage conversion, so it won’t replace a voltage converter for appliances that need it - USB power is limited (12 W max), so it may not suit higher-power charging needs - It’s aimed at specific plug types, you still need to verify plug compatibility for your destination
Who it suits best (and who should skip it)
It’s a good fit if you’re a UK traveller who wants plug conversion for US-style sockets and also wants to charge up to three devices at once using the built-in USB ports.
It might not suit you if you’re trying to run higher-power appliances, or if your device doesn’t support 100–250V and you’re hoping this adaptor will handle voltage on its own. If your priority is powering demanding electronics (rather than phones/tablets/small gadgets), you may want to look at a more suitable power/voltage approach instead.
How to use it for a typical trip setup
Imagine you arrive at a hotel that has only one wall outlet. You plug in this adaptor, then you can use the USB-C and USB-A ports to charge your phone and earbuds. If you also bring a device with its own plug (for example, another small charger), you can use the converted US outlet as well. The practical win is that you’re not juggling multiple chargers and extension leads—you’re using the one wall point you have.
And yes, double-check your devices’ voltage compatibility before relying on it, especially for anything other than standard phone/tablet charging.
FAQ
Does it convert voltage?
No. The adaptor does not convert voltage, so you need to ensure your devices support 100–250V, or use a voltage converter for devices that require it.
What can I charge with the USB ports?
The USB outputs are rated up to 12 W max and are described as suitable for phones, tablets, and other small electronics.
Can I charge multiple devices at once?
Yes, the 3-in-1 design allows you to charge up to 3 devices simultaneously using the US outlet plus USB-C and USB-A.
Which countries is it aimed at?
The description mentions compatibility in destinations such as the USA, Canada, Mexico, Colombia, the Philippines, and parts of Thailand.
Is it travel-friendly?
It’s compact and lightweight, made to fit easily into a travel bag for holidays, business trips, or daily use.
Final verdict
This EINNO UK to US Plug Adaptor with USB-C & USB-A is a sensible travel pick when your main needs are Type B plug compatibility and convenient USB charging for phones and smaller electronics. You should buy it if you’re travelling to US-style socket countries and your devices are 100–250V capable.
However, you may want to skip it if you’re expecting voltage conversion for high-power appliances or if your charging needs consistently exceed the 12 W max USB output described here.
