Battery Operated Starry String Light 100 LED (Included Rechargeable 18650 Battery) with Automatic Timer 8 Mode Copper Wire String Light for Christmas Outdoor Holiday Decorations (Warm White) selling for $ 5.66

I have seen plenty of 3AA battery versions, but this one uses a 18650, which is included.

As far as I could find out, a full charge takes you for around a week if you have the timer proper.

The box is the charger, that seems easy to plug/unplug to charge with a usb adapter.

I liked the idea here, seems to me all the good stuff come together on this one and the price seemed not too bad either.
