Power Fist 2000W Inverter Generator

Power Fist 2000W inverter generator with 1600W continuous output. It has 12V DC and AC outlets. The unit is approximately 50cm x 28cm x 45cm (19.7" x 11" x 17.7"). This provides portable power for camping or emergency situations. Bought brand new and I used about 4 or 5 times worked great and then its been sitting and won't start so easy tune up i'm sure but my camperized vehicle has a dc to dc charger so I boost my house batteries with that so I dont need.
