Looking for a Portable Power Supply

I've actually thought of making one of these.

My suggestion is to use a shitton of 18680 lipos in parallel to get the watthours you want, then use a boost converter to get the voltage up where you want it. If you want to Be fancy, you can put a power switch between the batteries and step up, and maybe a voltmeter and a LCD screen.

After that, just print a case and you're good.

Yeah you just buy another fucking laptop battery.

Just put a UPS in a backpack and carry it around. It's only like 40-50 pounds.

Not feasable when you're in the middle of a rendering job, sweetie

OP here, not very good at building electronics, though I will keep it in mind for a future project since I am planning on learning. Also, buying another laptop battery would be an option if I wasn't looking to keep my laptop on. >>61737041
