i wana make a portible outlet/battery packso i can use my corded drill outside (im to poor to buy a cordless one)
You cannot for less than you can get a cordless drill set for. The cheapest thing you can do is get an extension cord.
The only way that you can do this and not have it cost more than buying a cordless drill is to get a car battery cheap, maybe connect to the one in your car, and use an inverter to change the 12 volts from the battery to the 120 VAC for your drill. It's not real portable, but you can use an extension cord for thef AC just like you could if you were plugging into the wall. The problem is that a most batteries don't have a lot of capacity in them. Unless the drill is designed to run from a battery, you'll need a battery similar to a car battery to have enough capacity to run the drill for any length of time. Most drills have universal motors in them and can run off AC or DC. But you still need the 120 volts or very close to it to run the motor. This means putting enough batteries together to add up to 120 volts or converting a battery voltage to 120 volts. It'll cost about $40 for a 200 watt inverter. It'll cost more than that to buy enough batteries to add up to 120 volts. You should be able to buy a cordless drill with battery and charger for $40. It won't be the heavy duty, but it'll do for general home use. I had one I used for about 2 years untill I dropped it off a tower.
