Rechargeable battery pack for battery powered devices with a rotatably mounted plug

A rechargeable battery pack for holding at least one battery and for connecting to a battery powered device for supplying power thereto;

• the battery pack comprising:
• a case for holding the at least one battery;
• a recharging circuit connected to said at least one battery and disposed in said case;
• a plug including first and second prongs spaced apart from one another and generally parallel to each other, said plug being rotatably connected to one end of said case, wherein said plug is rotatable from a stowed position having the plug mounted flush with the case and the prongs recessed in the case to a first extended position with said prongs projecting from the case, wherein said first extended position is substantially orthogonal to said stowed position, and to a second extended position with said prongs projecting from the case, wherein said second extended position is substantially orthogonal to the stowed position and at least 180.degree. different from the first extended position, said prongs being electrically connected to said recharging circuit, the total range of rotation of the plug is at least 270.degree.;
• a battery discharging means connected to the at least one battery, wherein the battery discharging means is electrically connectable to the battery powered device for allowing the battery to discharge to the computer peripheral device;
• and
• a battery discharging circuit connected between the battery discharging means and the at least one battery for regulating the output of the at least one battery.
