MOMAX Universal Travel Adapter (100W Fast GaN) with 2 AC outlets and dual USB-C/USB-A ports
Product description
What it is and why you’d buy it
A universal travel adapter sounds simple, but in practice most people end up juggling two things: the right plug shape for each country and enough charging power for your actual devices. The MOMAX Universal Travel Adapter is built around both ideas, packing two AC outlets alongside multiple USB ports so you can charge phones, tablets, and USB-powered gear while still having proper plug points for laptop chargers and other accessories.
It also leans on a GaN approach and claims improved portability versus earlier versions, so it’s aimed at people who travel often (business trips, training, frequent weekends away) and want something compact that doesn’t feel like a compromise.
One important reality check: it’s not a voltage converter. If you’re bringing a device that expects a different voltage for safe operation, you’ll need to handle that separately.
The essentials (what you get and how it behaves)
On paper, this adapter offers a lot in a single brick. You get six total charging/output options: two AC outlets plus two USB-C ports and two USB-A ports.
For charging behaviour, the details provided focus on USB-C power delivery. When using a single port, it’s rated for up to PD100W across USB-C1/C2. The brand also states it can support two laptops at the same time (again, through the USB-C ports) and mentions a smartphone charging claim of going from 0% to 100% in 30 minutes—though real-world speeds can vary with the phone, cable, and its own charging limits.
What matters most for everyday use is the shared power concept: the total output can reach 100W when all ports are in use, but that generally means you’ll be relying on how your devices draw power. If you’re trying to push multiple fast-charging devices at once, keep expectations realistic and let device requirements do the talking.
Universal plug coverage (and the limit you should not ignore)
The adapter is described as globally compatible across four plug/socket shapes: A-type, O-type, C-type and Bf-type. It’s marketed for use in 200+ countries, with examples including Europe, USA, UK, Australia, Japan and others.
However, the adapter is only useful for devices with power less than 2500W, and it’s also not a voltage converter. So while the plug shape may fit, the device still has to be compatible with the electrical requirements you’re plugging it into.
Worth noting if you’re buying for mixed travel: some hotel/airbnb setups include high-power appliances, and this is not designed for running anything like that. For chargers, small electronics, and typical travel power needs, it’s designed to be the “one thing that covers it” solution.
What stands out in day-to-day use
This model positions itself as more portable than previous versions and adds a practical improvement to the front AC socket to reduce poor contact and make plugging/unplugging easier.
There’s also a convenience angle: when not in use, the plug is partially tucked away so it doesn’t get in the way. That’s a small detail, but it can genuinely matter if you’re packing this into a sleeve alongside cables and chargers.
Also, having two AC outlets can remove a headache when your device lineup doesn’t all charge neatly via USB. For example, you could use the USB-C ports for a laptop charger (if it supports USB-C PD) and a phone, then use an AC outlet for a specific adapter, power brick, or accessory that doesn’t take USB.
Safety and build considerations
The adapter is described as ROHS, CE and FCC certified, and made from GaN cooled fireproof PC material. It includes multiple protections (such as overheat, overcurrent, overcharge, short circuit protection, overpower protection, overvoltage protection, overdischarge protection) plus a built-in 10A fuse.
It’s not something you see while you’re travelling, but it’s the kind of “boring” engineering detail that matters when you’re plugging in expensive tech in unfamiliar outlets.
One limitation to keep in mind: no voltage conversion means it’s not for every appliance scenario, even if the plug shape fits. If you’re unsure about your device’s voltage and power requirements, check before you pack.

Final verdict
It makes sense if you want one universal travel adapter that covers more than just “stick a plug in”—you need both AC outlets and a mix of USB-C and USB-A for fast device charging. The 100W PD headline and the multi-port setup are especially relevant if you travel with a laptop plus phone/tablet and you’d rather avoid carrying separate chargers.
You may want to skip it if any of your devices require voltage conversion, or if you’re planning to run higher-power appliances (the adapter is positioned for devices under 2500W). It’s also worth remembering that charging performance will depend on what your devices can draw, the adapter can supply power, but it can’t override device limits.
Mini FAQ
Can this adapter be used as a voltage converter?
No. The adapter is not a voltage converter, so it’s important to confirm your device’s voltage requirements match what you’ll be plugging into.
Will it work in the UK and the US?
It’s described as globally compatible, including plug use for both the UK and the USA, and it supports multiple plug/socket types.
How many devices can I charge at once?
The provided information states it supports six ports total, meaning up to six devices can be charged at the same time.
What’s the key limitation on device power?
It’s only compatible with devices with power less than 2500W, based on the included notes.
Should I expect full 100W charging for every device combination?
Not necessarily. While it’s rated up to 100W in total and up to PD100W per USB-C port under specific conditions, real charging depends on how your devices negotiate power and how many ports you use simultaneously.
