Power Inverter------Must escape shitty DSL-------HELP!

OK quick question, what kind, brand, and wattage power inverter would I need to power a ps4 and a GAEMS vanguard 19" portable gaming gaming environment?

Look at the power ratings of the devices you want to run, add up the wats.. add 10% safety and there you go.

But how does that save you from DSL?

This is a dumb idea.

Unless you are the hulk or superman this plan of yours will end in disaster.

I plan to go around to various establishments in my car and leech off of the wi-fi....until they start to complain

Are you doing this for playing online or just downloading. If playing there has got to be a better solution.
