Pros and cons

Pros

Combines eight AC outlets with three USB-C and two USB-A ports in one tower.
Individual switches offer a way to control connected AC devices without unplugging them.
The 2-metre lead and vertical layout may help organise a desk or shared charging area.

Cons

USB ports remain powered when the individual AC outlet switches are off, so those switches do not control USB charging.

Only aggregate rating information is supplied, with a distribution weighted towards five-star ratings but also a smaller one-star share. This offers limited context rather than explaining users’ experiences. It does not establish performance or resolve the listing’s differing USB-output and protection details, which matter when choosing it for charging equipment.

Frequently asked questions

How many devices can it connect?

The listing claims eight AC outlets and five USB ports, describing the total as 13 devices. Actual use depends on the devices and the available power limits.

Do the switches control the USB ports?

No. The listing says the USB ports are always powered and are not controlled by the four individual switches.

What USB charging output does it provide?

The listing gives differing figures: 2.4A maximum per USB-A port and 3A maximum per USB-C port in one section, and 12W and 15W maximum respectively in another. Check the selected listing for the applicable output.

Does it have surge protection?

The listing describes it as surge protected and mentions an overload protection button, but provides no surge rating. Treat the protection specification as unconfirmed.
