With this power supply you no longer need to change batteries in our 3 types of bright battery light bases. Plug it into the socket and connect the cable to the light base.
You can still use batteries together with the power supply. If you mainly use the power supply, we recommend removing the batteries.
If the light base is far from a socket, you can use the cable alone with a USB power bank. How long the light lasts depends on the size of the power bank. Test that it works first. Some power banks switch off when the power draw is low, especially with the smallest light base. We cannot guarantee that the light base and cable work with all power banks.
Please note: Light base and power bank are not included.
