like the devices the solar panels are of very good quality
I use this with the curtain motors to open and close curtains in my parent's Long Term Care home, since during covid I cannot enter and staffing is very low and my parent cannot open the curtain themself. The fact I do not have to worry the power cable will come unplugged or the battery will die, I so not have to worry this will stop. ALL Switchbot products should have this as a capability, so that the can work completely remotely for months.
SwitchBot Solar Panel
Awesome way to save energy by using the sun to charge the batteries
