There is plenty of power from the 8HP 4 stroke OHV engine giving up to 2800 Watts that is sufficient for most devices. There is an 11 litre fuel tank that will keep the generator running for around 10 hours per re-fill so can be filled in the morning and left to run all day. Other features include an automatic voltage regulator, air cooling, surge protector and rubber engine mounts that help keep the noise level down to a lower than normal 66dB.
