You learn the source must be about double the load. Example. Your car loafs along at 60 but might hit 120. So many other examples.
Let's use 100 Watts for 5 hours to give headroom on capacity. You'll need a battery and the invertor.
Examples:
https://www.batterystuff.com/kb/tools/solar-calculator.html gets me a figure of 42.500 Amp-Hrs (42 and 1/2.)
Nice sine wave convertor: https://www.amazon.com/Watt-Pure-Sine-Wave-Inverter/dp/B01N3UJS4U (99.99 bucks.)
Deep cycle battery: https://www.amazon.com/Universal-Power-Group-Battery-UB12500/dp/B00573EI76/ (under 90 bucks.)
Or get a Yeti. https://www.amazon.com/Goal-Zero-23000-Solar-Generator/dp/B00D5RVMAM
I have created a portable TV rig for my use in coaching in a high school gym. I can certainly power it with a long extension cord, but was wondering if there was a good product out there to power it portably. The TV is a 75W LED flat screen. I also need to power an Apple TV device. Any suggestions for something that won't cost too much and that would last at least 5 hours?
Thanks,
Dave
