A Fine Product!
By Javier A,

Review Posted 09/15/2020
I am a mechanic, I work on heavy duty equipment (Contruction). I have used this Generator in job sites, under the rain and heavy sun exposure, so far no complaints. The CAT INV4000 is capable of handling a 110V Mig welder and some other accessories at the same time like an industrial fan and a saw. Very economic, I suggest to use Ethanol-free gasoline only to get the max out of it in therms of efficiency and durability. If you are not planing to use it every day I highly recommend to plug it to the wall using the provided charger/maintainer.

Awesome, I love it. Too soon to make any detail comments. Hookup was easy, very quiet and ran smooth the very first. Have not attached any load yet, but I am sure when I do, there will be no problem.
