The Honda EC5000 is a single-phase AC 115/230V portable generator with 5.0 kVA of maximum power and 4.5 kVA of rated power and 50 Hz of rated frequency. The EC5000 generator is available with 115/230 V rated voltage (B type) or 230 V only (F, GV, IT types).
The Honda EC5000 generator uses single-cylinder (inclined by 25°) Honda GX390T1 gasoline engine (389 cc; 23.7 cu.in.). The Honda GX390 K1 has overhead valve design, single-cylinder inclined by 25°, transistorized magneto ignition system and horizontal carburetor with a butterfly valve. Bore and stroke are 88.0 mm (3.46 in) and 64.0 mm (2.52 in), respectively. Compression ratio rating is 8.0:1.
The GX390 produced 13.0 HP (10.0 kW) at 3,600 rpm of maximum horsepower and 27 Nm (2.7 kg·m, 20.0 ft·lb) at 2,500 rpm of torque.
