The Honda E2500 is AC/DC portable generator with 2.0 KVA of rated power, 2.5 KVA of maximum output power and 50/60Hz of rated frequency (depending on model). The E2500 generator is available with AC 115V, 220V, 240V or 115V/230V (depending on model). The direct current terminals can be used for charging 12-volt automotive-type batteries only up to 8.3A.
The Honda E2500 generator used the Honda G300 single-cylinder gasoline engine with 272 cm3, (16.6 cu·in) of displacement. The engine has a side-valve (L-head) design, a splash-type lubrication system, and a horizontal carburetor with a butterfly valve and flywheel magneto or CDI (on KA and KE models) ignition systems. The cylinder bore and the piston stroke are 76.0 mm (3.0 in) and 60.0 mm (2.4 in), respectively. The compression ratio rating is 6.5:1.
The engine produced 7.1 PS (5.22 KW; 7.0 HP) at 3,600 rpm of maximum horsepower and 17.4 Nm (1.77 kg·m; 12.84 ft·lb) of peak torque.
