In contrast to the DH series which is a more conventional type generator. This means that , even though it produces more noise and consumes more fuel, it could have been much less expensive in the absence of all the extra features. For instance, the electric start feature for the engine, which is certainly very nice.

Unfortunately, outlets aren't being used. But it's certainly an easy fix if you need to.

In the end its cost, versatility as well as its performance, more than compensate for the cost. This is an excellent portable generator for pumps that are in the 3-HP range.

  • Pros

If you own an even more powerful pump, you require the right generator to compete with the pump's power. The A-iPower dual fuel generator can be used as much as 9000W (12000W peak) using gasoline, or 8500W (10800w peak) using propane. This gives you enough space to fit your pump as well as other equipment.

It's outfitted with a 50A receptacle to provide the capacity to handle a larger amount of current. It also includes a 25-foot extension cord for a free.

The only issue is that it only comes with two years of warranty as opposed to the three years offered by other. Though I'm sure you can believe in the quality of A-iPower, an additional year would have been very nice.

If you're able to accept that, then this generator will leave you feel happy.
