One Beat OB4WAUTC2 30W Desk Clamp Power Board

One Beat OB4WAUTC2 is a desk-clamp power board with four AC outlets and USB charging ports, including a claimed 30W USB-C PD port. Its clamp-mounted layout suits a fixed workspace, but customer feedback is mixed on how securely the clamp holds.

At a glance

Clamp installation is described as tool-free, with foam pads intended to reduce desk-surface scuffs.
Four AC outlets are spaced 4.5cm apart, which may leave more room for bulky plugs.
USB charging is claimed to include a 30W USB-C PD port. The listing says output changes when multiple USB ports are used.

What to know before buying

Listing details to confirm

The outlet and USB count is presented inconsistently: one description says two USB-A ports and one USB-C port plus a 30W USB-C PD charger, while another says two USB-C and two USB-A ports. The USB charging output also changes by port combination, so confirm the exact port layout and simultaneous-use output for the selected listing. Customer feedback is mixed on clamp strength, so consider desk thickness and fit before relying on the mount.

Who is it for?

A good fit for

Home-office or study desks where edge-mounted power access is useful.
Buyers who want several AC sockets and USB charging ports at the workspace.
Desks up to the stated clamp thickness where a fixed, removable mount is preferred.

Less suited to

Buyers who need a guaranteed clamp grip without checking desk fit.
People who require a specific USB port count or full 30W output while using several ports at once.

Customer feedback describes the power board as well-built and useful for organising office desks, including work-from-home setups. Opinions on the clamp are mixed, with some finding it secure and others calling it weak. That matters for a desk-edge product: the claimed clamp range is up to 5.5cm, but positive general feedback does not establish that it will hold firmly on every desk.

Positive themes

Customers report good build quality and useful desk organisation.

Mixed feedback

Feedback on the clamping mechanism is mixed. Some customers find it holds firmly, while others find it weak.
