I have this package. The powerbank i can continiously charge during the day with a solar panel.
I lightup the usb bulb with a hp charger ongrid. In case of power outage i want to switch automaticly to the powerbank.
How can i do this?? There are currently emmergency lamps on the market which automaticly switch to the battery in case of power outage. I want to simulate this with my package (see pict)
