Awesome experience!! Super fast shipping, great communication, excellent transaction!
Fast service, shipping and follow up
I ordered two generators on-line after talking to a representative by phone and the generators arrived the NEXT DAY! Not only was the delivery incredibly prompt but the phone representative took several of my calls to answer follow-up questions. Could not have been a better experience!
First I think it was Andrew who took my call when I had questions about these generators. He was extraordinarily helpful and efficient. He sealed the deal. So we bought them. They started right up. We are very happy with them. The lower level of use made the decibel level acceptable.
I am hopeful these will be great in an emergency although I would have preferred an electric starter. Larry made the order process and first start a breeze!
The seem to work well, however one of them uses fuel more quickly and does not run at constant speed but speeds up and slows down even if there is no load. I tried charging my John Deere electric Gator with that generator, however the 48V charger failed and tripped the generator breaker. I donâ€™t know why the charger failed. The charger uses only 1kW of AC power so it is unlikely that the charger overloaded the generator. Service department told me if I had problems with the generator I should take it to their local service shop.
I recently purchased two of these for use with a travel trailer. Communication with vendor was good, and delivery was as promised. Well done!
The Yamaha EF2200Ois combo inverter generator ran my 3000w RV air conditioner unit great. I had no problems starting or running it. Having two generators that I can lift independently is way better than one larger generator that I can't lift by myself.
Thank you National Supply!
Called in on a Monday and had my generators buy Thursday just in time for my trip. Packed very good no damage and they had excellent customer service. Will use again if ever needed .
So appreciated Larry in customer service for his time and expertise in helping us understand what we needed to meet our expectations. Kudos.!
