※ This is a simple light that turns on when you touch the top. However, I have lost the instruction manual, so I ask that you operate the remote control yourself. Thank you for your understanding. There are no noticeable stains, but please understand that this is a used item. ※ Rechargeable. There is no charger, so please prepare a Type-C charging cable. ※ The remote control batteries are not included, so please prepare the batteries listed on the back. The remote control has detailed functions such as a timer, but you can turn the light on and off by touch even without the remote control. I think it's convenient for bedtime or nighttime feeding. ※ Depth 9.5cm x Width 9.5cm x Height 13cm Material: PP+PC Rated voltage: DC5V Operating time: 13-200 hours Charging time: Approximately 4 hours (using a 5V1A adapter) Remote control distance: 5m Max
