Yamaha has a reputation for offering reliable, high quality generators that suit a variety of needs. A middle weight workhorse is the Yamaha EF2400iS. It retains Yamaha’s signature charms, most notably being ease of use, portability, plenty of power and a brilliant blue design.

Now Yamaha has updated the EF2400iS. Within the same basic package comes the EF2400iSHC. This high-current brother to the EF2400iS offers even more options for users. Like the EF2400iS, the EF2400iSHC is able to handle most tasks in the workshop, at the job site or out camping. The EF2400iSHC, however, has the ability to start up and run large appliances such as refrigerators and air conditioners.

What exactly is the difference between the two generators? From the outside, they look nearly identical. Both run at a continuous 2000 watts with a peak operating wattage of 2400 watts. However, Yamaha has updated the control circuit board in its EF2400iSHC. Packing the new generator with high-current technology, most notably the new field effect transistors, gives the EF2400iSHC more current available to start high-demand appliances.

What does this mean for the user? If the EF2400iS ever had any trouble or hesitation starting large appliances, the EF2400iSHC surely won’t. Yamaha’s claim is that the EF2400iSHC won’t break a sweat starting a 13,000 BTU air conditioner in up to 110 degree Fahrenheit temperatures.

What makes the EF2400iSHC an exceptional choice over the EF2400iS is that it doesn’t give up its predecessor’s portability. Despite being equipped with the new high-current technology designed to give it a much higher surge output, the EF2400iSHC hasn’t gained any weight or bulk in the process.
