Only used half a tank of gas powering essential circuits. Have it connected and tested to natural gas. Works great so far

When unpacking and preparing the generator the strap to hold the battery was found to be broken. Thanks for emailing me as I forgot about this strap, Please let me know how I can acquire another. The unit runs well but is a little louder than I had expected.

TMG 10500 generator

Tremendously impressed with how this was packaged up for shipment - almost bullet proof. In addition, the generator was everything I wanted and is performing perfectly...currently 5 hours on the clock during the break in process. This is basically the same unit as the Genmax 10500 sold in the USA as well as the Pulsar 10500 for the same money but in American dollars. Ordering from TMG saved me Canada/US duty, excessive shipping charges across border, and sales tax if I had ordered the same unit directly from the USA. I looked up the Changching Dinking corporation (SP) who makes this unit in various formats, and sold under various brand names, and am quite impressed with the quality of manufacturing this Chinese company would seem to put out. I am also thoroughly impressed overall with the modern feature set on this generator. My only concern would be about warranty and spare parts should I need them. I am a bit of a generator "junkie" and I own 9 generators (don't ask) including 4 Champions, 1Honda EU 6500, 1 Maxkeepingrod 3500 and 2 smaller Powermate 1200 units, so I don't impress easily. I bought this larger unit strictly for home backup using natural gas for use with my Generlink whole house electronic transfer switch. This unit is a perfect match for my home backup needs and in the short time I have had it, I am 100 percent satisfied. Time will tell of course....

It arrived in good shape and once filled with oil and gas, started on the first pull. I have used it a half dozen times and it starts even when sitting outside below freezing. It handles the load well but shuts off if overloaded which is a good feature. It’s as noisy as the small Yamaha I had but a more low frequency and pleasant sound. I have only 30 hours or so on it but so far so good.

Runs all my tool even my double head wood planer thats 220v 30amps. Very impressed. The auto gen start for the solar back up is working great. Compared to the Honda generator…definitely not the same quality but I can buy 2 for one Honda generator at 7000 watts and it’s not big enough to run all my tools. This 15000 watts is very impressive…
