Top 3 Customer Questions & Concerns ‍

 How do I verify this is the correct size? The 4.0mm x 1.7mm size is very specific and can easily be confused with larger 5.5mm plugs. For a guaranteed fit, it is recommended to use a digital caliper to measure the center pin and the outer port of your device before ordering.

Will this change the output of my charger? No, this is a passive adapter. It only adapts the physical shape of the connector and does not convert or regulate voltage. Always ensure your power supply's voltage and amperage match the requirements of your device.

 Is the connection firm enough for portable devices? Yes, the precision-machined barrel and internal socket contacts are designed to provide a firm mechanical lock, reducing the risk of power loss due to accidental disconnection or cable movement during mobile use.
