Its a simple cordless screwdriver, but it runs on replacable alkaline batteries. Bought it at WalMart a few years ago for $8. They still sell a simular version. I love it because if I need it and the batteries are low, I always have AA's laying around to get it going again, right away.

used it today, i gave on the throw aways and bought some new rechargeable AA's for it
I learned to remove the batteries when storing it, for some reason it sucks the batteries dead, iF i leave them in there
Options, always have options, and the journey goes much smoother ....

I have changed to rechargable nickle metal hydride batteries years ago, and always recharge them when they are about 1/2 dead, so I think they will last much longer. I get them at Harbor freight, they are not as expensive as a 36 pack of disposable AA batteries, and last much longer.
I use a slightly larger drill that has a 4 volt battery by Ryobi to remove hundreds of screws each week while repairing air conditioners. I have slightly heavier drills for actual drilling or for when I need to remove heavy things, but the light one fits in my pocket easy, and is lighter than three nutdrivers it replaces. Nice thing is the 4 volt battery also fits the infrared thermometer, and some LED flashlights, so I keep them around with fully charged batteries, ready to go if one or the other runs out of juice.
The 18 volt Ryobi drill kit came with a small circular saw, sawzall, and very bright light too. It comes in handy when working on units in the ceiling.
i use a 7.5 small makita dril, and i thru the batts away and ran an old vacuum cleaner wire from it to a cig lighter plug. now when i need a drill, its always ready to use, no dead batteries to worry about. runs great on 12 volts
I've got one too and find it great at loosening really tight screws in the lock mode because of the much better grip it offers. For an actual power screw driver I really like my B&D LI drill/driver that has the "Smart Select" feature.

I have found from experience that the rechargables are not good for shelf life. They go dead by themselves quickly. The Alkalines, on the other hand, have shelf lifes of up to 7 years.
I have this little guy and it will hold a charge for almost a year just laying in my tool box. It came with a mtching high speed Dremmel tool and a charger. It is strong enough to drive a 2.5" deck screw into new treated lumber. Too bad they discontinued it.
