I had an old Black and Decker cordless drill which was cheap but worked but it was never a very powerful drill and charging the battery was a problem as it was on the go had to be. drill. When the battery ran out of charge, I decided to get a new Ryobi with the 2 batteries that came with it. Now I can use the drill with one battery and charge the other battery with an external charger. And he's strong enough to get the job done. love the world!
