1 / 7One 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.
Pros and cons
Pros
- The clamp-mounted design keeps the outlets at the desk edge and avoids leaving the board loose on the floor.
- Four AC sockets plus USB charging offer several connection options in one desk unit.
- The listing specifies 900 Joules of surge protection.

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.
