2. Socket hole protection door, double protection door design to prevent unipolar insertion, reduce safety faults.
3. Socket copper high-quality tin phosphor bronze, high strength, good elasticity, no deformation, high conductivity
4. Equipped with multi-function 220V socket, you can adapt to the use of various plugs.
5. Low-power LED charging indicator.
usb socket use caution
1. Avoid usb socket contact with water, to know that water can be powered, although the general usb socket is now tested by the standard quality, in order to be safe, we still have to pay attention.
