Our long seller Koma lights use USB cables to charge.

The cables are not included with the lights because, its more likely that people have at least one USB cable in their homes.

However, the USB cables that have a big head doesn’t work well with the lights.

Try to find a USB cable that has a small head like the one in the right.

The width of the head was 0.15m, if you are wondering .
