Clarke CIR-13
Price: £24.66 (12V) Claimed maximum torque: 115lb/ft
Sailed through our torque tests, even at 5Ib/ft more than its maximum torque rating. The price is keen, the four sockets tackle 17-23mm nuts, the 3.96-metre lead is the longest here and a battery adapter is thrown in. A clear 12V Best Buy.
