What to know before buying

Listing details to confirm

USB charging details are inconsistent: one feature claim specifies USB-A at 2.4A and USB-C at 3A per port, while the product description gives USB-A as 12W maximum and USB-C as 15W maximum. Confirm the output figures for the selected listing. USB ports are stated to remain powered when the AC switches are off. The listing also describes overload reset instructions, but does not clearly establish surge protection in the feature details.

Who is it for?

A good fit for

People who need a long reach from a wall socket to a desk, home-office setup or dorm room.
Setups that need several AC outlets alongside USB-A and USB-C charging connections.
Users who want separate switches for AC-connected devices.

Less suited to

Buyers who need clearly consistent USB charging-output specifications before purchase.
Anyone who needs the USB ports to switch off with the AC outlets, since the listing says they remain powered.

Customer feedback is represented by aggregate ratings only, not written review details. The distribution is mostly five-star, with a smaller one-star share, so it suggests generally favourable but not uniformly positive experiences. Those figures do not identify reasons for praise or criticism, and cannot confirm the stated outlet, cable or USB performance.
