Im wondering what you all think of this idea. I bought a cheap Hp powerbank and charged it full and connect a usb 5watt led lamp to it. It burned more than 3 hours. The powerbank consists of one 18650 li-ion.
I also did charged this powerbank with a 6volt 3wp panel. Works fine.
I have a seperate toilet and douche cabine. So in each i installed this. Also in my bedrooms and small hall.
In the meantime im able to make my own powerbanks with different cheap charging modules. Works also fine. Testing now for my living room with a powerbank consisting 4x18650 batteries and burning 2x7watt usb bulbs for approx 5-6hours per evening.
You go shower 5-10 minutes and you turn off the lamp. So its sure that such a cheap setup is suitable for what i call "on-off spaces".
I frequently read about systems for a shed or camping and i thought ..wow... Why a relatively big system???
Anyone else experimenting with 18650 batteries for home permanent lighting, not emergency lighting (off grid lighting)???
