Tell us about yourself!
I've made one of these in a larger scale using a solar charger and 50 watt panel, a type 31 battery and battery box. It is the same thing with much more capacity, but less portability. I can plug a 400 watt inverter into the 12 volt power socket and charge my laptop or run any number of small radios/cd/dvd players etc.... I put a 12 volt fan in the tent and its all good! I use it mainly of an evening or night time when lighting (12 volt solar strips) or music etc... is needed. The one shown here is just smaller but is perfectly designed. Scale it up as big as you want. Great job!
