Power-only Micro USB cable with on/off switch

This Fervit cable carries only DC 5 V power up to 3 A and does not transfer any USB data. It is intended for low-power devices such as LED lamps, small fans, dash cameras or phone charging where a data connection is not required. The inline push-button lets you cut power without unplugging the connector.

Inline button reduces connector wear

Pressing the switch opens or closes the power path so you can turn a device on and off without repeatedly inserting or removing the Micro 5-pin plug. This mechanical action spares the port from physical stress and extends the usable life of both the cable and the device socket.

No data lines — charging only

The two-core construction omits the data conductors entirely, so the cable cannot be used for file transfer, tethering or any communication with a computer. It also lacks fast-charge protocol support and must not be connected directly to a Power Delivery charger or high-power host.

Questions about this item

How long will the Micro 5Pin connector last before it needs replacing?

The built-in on-off button lets you cut power without unplugging, which reduces physical wear on the Micro 5Pin male and female ports and extends the cable's usable life.

What stops me from drawing more power through this cable during continuous use?

The two-core design is rated for a maximum of 5 V / 3 A and does not support fast-charging protocols, so any device that tries to pull more current will hit that hard limit.

Does the switch or cable get hot when I leave a USB fan running all day?

The cable only carries DC power with no data lines, and the mechanical switch adds negligible resistance, so heat rise stays minimal during extended low-power operation.
