If you are a camper or a tailgater then you would need to light your camp, or your RV, run some small appliances like your projector for arranging a movie night, power your speakers to play some music, or use the charging adapters.

All of these appliances don’t demand much power and therefore you wouldn’t have to carry a heavy-duty 12k or 24k watts generator with you.

Engine And Power:

Generac GP 2500i has a capable and fuel-efficient engine that is a four-stroke OHV engine powered by a single-cylinder 98cc invertor engine.

This engine produces 20.8-ampere power as its peak amperage while its running amperage is 18.3 and this running amperage is more than enough to let you charge multiple devices at a time.

You can use this small generator to power a heavy-duty appliance for a while but it won’t power it for long or power multiple appliances simultaneously.

In simple words, the Generac GP2500i won’t power you an air conditioner, refrigerator, microwave, or TV at the same moment but you can run the AC or microwave one at a time.

The same goes for your TV and refrigerators. This rule doesn’t apply to small appliances and you can run various small appliances all at once without a mind about which one to off and which one to let run.


The runtime of any generator is complementary to its fuel tank capacity and the fuel efficiency of its engine. This Generac GP2500i portable generator review has a good and highly fuel-efficient engine but it doesn’t have a large fuel capacity tank.

You can only put 1 gallon of gasoline fuel in it and this automatically reduces the runtime of this generator compared to other generators with large fuel tanks.

The average runtime of GP2500i is 8 hours operating it at 25% load such as running it at the minimum appliances during daytime in your RV.

But increasing the load at night will reduce the runtime but let you use it for longer if you let the RV run on 50% load all throughout the day. Therefore, the runtime of GP2500i will become 4 hours at 50% load capacity.

Fuel Capacity:

The fuel capacity of Generac GP2500i is 1 gallon and it is powered by gasoline fuel. The gasoline fuel along with an efficient OHV engine will give you the maximum power supply that is needed to run your RVs.

This Generac GP2500i generator has multiple receptacles to match your requirements. You can use the AC or DC outlets depending on your need.

One commendable feature of this generator is that it also allows you to the USB ports where you can directly charge your smartphones and connect speakers having USB Type C connectivity.
