Top 3 Customer Questions & Concerns ‍

 Why is the tip colored white and yellow? The White and Yellow tip is an industry-standard visual cue used to distinguish this 2.5mm inner diameter plug from the more common 2.1mm black-tip plugs. This helps prevent accidental mismatching which can lead to intermittent power issues.

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

 Can I use a 2.1mm plug in this 2.5mm adapter? The female socket end is designed specifically for a 2.1mm plug. The male end (the yellow/white tip) is meant to go into a 2.5mm device port. This adapter effectively lets a smaller cable fit into a larger hole.
