If you’re looking for an electric screw driver then Black+Decker’s new cordless tool- 4V MAX Lithium Pivot Screwdriver could be an excellent choice for one good reason that you can charge it from the same USB adapters you use to charge your smartphone or tablet.
The electric screw driver features a three-position handle that can be rotated at 90 degrees for either pistol-grip or inline orientations in tight spaces. The $40 drill comes with a micro USB wall adapter that provides a 400 milliamp charge rate. The 4V MAX is also equipped with a Lithium ion battery that holds a charge for up to 18 months.
The spindle lock mechanism offers better control when manual screw driving is needed and the forward and reverse rocker switch enables you to easily switch the tool for screw driving or screw removal.
