One reviewer mentioned that his came with only 4000mAh cells and that he contacted the seller to change the listing. I don't know if you can believe what's printed on the label but mine came with 5000mAh cells, so take that for what it's worth. Overall, these are great little all in one solutions for anything that needs 6v or 12v. The quality seems fine and the waterproofing seem okay, but only time will tell!

I received this generator in the evening and the box was in tatters. The only thing holding the cardboard to the gen was a fiber strap around the box. The Generator was in fair condition despite the very poor shipping container. There is a small dent in the motor cover that does not affect operation. I let that slide. The powder coating on the frame and handles has spots that are not entirely coated and the metal shows through. Again this doesn't affect operation. The assembly was straight forward and the wheels while cheap plastic are more that sufficient for moving the gen around. The oil dipstick and fill hole are awkwardly placed under the motor and very low to the ground. You might want to consider a ramp and table to work on this gen if you have back problems or limited mobility (squatting, getting on hands and knees, etc.}. Put something under the oil fill hole, catch pan, cardboard, something to catch the inevitable oil spill. The oil they send with the unit is .74 quarts which is what the generator says it holds. Unfortunately, you cannot just fill it, as it will have some oil in it from factory testing and this means that the oil will spill out if you just fill it up. (I am speaking from my experience, your mileage may vary.) Fortunately, I had laid thick large carboard sheet down before filling the oil. This prevented the mess I could have had. {I should have used a clean pan to catch the oil and put it back in the bottle.) The unit is heavy. Be aware of this and do not try to pick it up alone unless you are used to lifting heavy weights. Use the handle and wheels and the gen is easy to move. I have run the generator with a very light load for five hours to break the motor in, according to directions. The engine started after three pulls with the choke on and ran very well after the choke was turned off. I ran a meter on the load and found the voltage to be 121v under light load and 61hz. I suspect, under a running load, this will come down to more operational ranges. I will update once I have the electrical connections to my power panel installed and have tested the unit under various loads. NOTE- This Generator has a high harmonic distortion of less than or equal to 23% listed in the manual and on this site. You can research this. My finding was that it probably won't matter for most things. Anything that has a power block is probably converting to DC power and so will not be a problem. If you are concerned or have a LOT of high value electronics, you may want to consider a more expensive inverter generator that produces "clean power"
