Universal USB Fan Power Adapter

The Vszerda cable powers two 3-pin or 4-pin PC cooling fans from a single USB Type-A port. It suits builders who need extra airflow inside a chassis or owners of consoles, routers and AV gear that only offer USB power. The 24-inch length reaches most internal fan headers without strain. The black braided sleeve keeps the installation tidy.

Integrated 12V Step-Up Module

A built-in booster converts the standard 5V USB supply to 12V at 0.4A maximum, letting connected fans spin at full rated speed. This removes the voltage drop that limits typical USB-powered fans. The circuit also works with PWM controllers and fan hubs, so speed control remains available when the host device supports it.

Dual 3-Pin/4-Pin Output Connectors

The adapter terminates in four female headers, two per fan, accepting both 3-pin and 4-pin plugs. Buyers who need more than two fans or a higher current budget than 0.4A total cannot use this cable. The fixed USB Type-A plug also means the host must supply standard USB power without negotiation.

Questions about this item

Will the step-up circuit need replacement if I run two fans continuously?

The built-in 12V step-up circuit is integrated into the cable assembly and rated for 0.4A maximum output; no separate module is user-replaceable.

What limits total fan speed when both headers are used at once?

The shared 0.4A current cap from the USB 5V source splits between the two 3-pin or 4-pin connectors, so combined draw cannot exceed that figure.

How much heat does the booster generate during all-day operation?

The voltage booster is embedded in the connector housing and designed for continuous 0.4A load; the black nylon sleeving dissipates warmth without active cooling.
