Included with the cordless screwdriver itself, two batteries, charger and 2 bits for cross and slot screws are included. The Skil cordless screwdriver operates at 12 volts and is perfectly adequate for home use. However, you should not expect miracles. After the battery has been charged, which takes a long time you go. I welcome the fact that a second battery is so that the long charging time does not fall so significant. The workmanship is good and makes a stable impression. Overall, a good buy for those who want to quickly screw times a shelf together.
