Pros and cons

Pros

Three USB-C ports plus two USB-A ports allow multiple USB devices to connect without a separate USB hub.
USB-C1's listed 70W single-port output is intended to support compatible laptop charging.
The listed Type C, G, I and A plug standards cover common destinations in Europe, the UK, Australia, Japan and North America.

Cons

When multiple USB ports are active, the listed maximum shared USB output is 45W, which can reduce charging speed compared with using USB-C1 alone.

What to know before buying

Listing details to confirm

Listing details are inconsistent: the title and feature copy claim 70W maximum, while technical details specify 70W for USB-C1 alone and 45W shared across multiple USB ports. Dimensions also differ between 3.03 x 2.17 x 2.11 inches and 3.03 × 2.16 × 2.10 in. Confirm the selected listing's exact configuration and shared-output behavior before purchase. This is a plug adapter, not a voltage converter. Check the device label for 100-250V, 50/60Hz compatibility. The listing also advises against high-power loads over 2500W and says multiple-port use may slow charging.

Who is it for?

A good fit for

Travelers who want one adapter with USB-C, USB-A and AC connections for several devices.
People carrying a compatible laptop that can charge through USB-C and need up to the stated single-port output.
Travelers visiting destinations that use Type C, G, I or A sockets.

Less suited to

Anyone needing voltage conversion for a single-voltage appliance.
Buyers who need a guaranteed 70W total while charging several USB devices at once.
Users whose high-power AC device exceeds the listed load limits.

Customer feedback describes the adapter as useful across multiple countries, with reported appreciation for its versatility, extra USB ports and ability to charge several devices. The listing's five-port design aligns with those reported uses, but its stated 45W shared USB maximum matters when charging multiple devices, especially a laptop. Value opinions are mixed, so the reported satisfaction does not establish that it suits every travel setup.

Positive themes

Customers report useful multi-country operation, convenient extra USB ports and charging multiple devices.

Mixed feedback

Customer opinions about value for money are mixed.

Frequently asked questions

Does the MOMAX UA8A convert voltage?

No. The listing explicitly says it does not convert voltage. Check that an AC-powered device is rated for the destination's voltage before connecting it.

Can USB-C1 provide 70W while other USB ports are used?

The listing gives up to 70W for USB-C1 alone and a 45W shared maximum when multiple USB ports are used. It does not establish a 70W USB-C1 output during multi-port charging.

Which plug types does it support?

The listed plug standards are Type C, Type G, Type I and Type A. Confirm the destination's socket type before travel.

Can it power a laptop?

The listing describes USB-C1 as suitable for compatible laptop charging up to its single-port rating. The laptop must support USB-C charging, and multi-port use has a lower stated shared output.
