Generac GP2500iGenerac generators are particularly renowned for their heavy-duty appraisal and large load-carrying capacities. But you don’t have to dishearten yourself as you can also find a great quality Generac generator that is meant for low loads or minimal power supply requirements.

Generac GP2500i Review

If you want to have an efficient portable generator that is your go-to choice for tailgate parties and camping then this Generac GP2500i is your best buddy.

So, let us have a detailed account of its features and specs to decide if this robust and compact generator is a worthy choice for tailgaters and campers or not.



Generac GP2500i portable generator has the peak watts of 2500 which are its starting watts while the running watts of GP2500i are 2200.

Fuel Type and Capacity:

The GP2500i like other generators in the series runs on Gasoline fuel and has a small fuel carrying capacity of holding 1 Gal fuel.


Generac covers 3 years consumer limited warranty as their standard warranty applies to all of their listings. This is a limited parts guarantee and doesn’t cover intentional damage


Generac GP2500i has a runtime of 4 Hrs. and this is possible at only 50% Load. If you reduce the load to 25% you can enjoy the generator running for 8 hours.


Generac GP2500i is a small and compact generator that is designed considering the small power requirements in outdoor areas.

If you are a camper or a tailgater then you would be needing to light your camp, your RV, or 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.

This is where a small robust buddy like GP2500i will be more than enough for your needs and you can easily carry it along with you whenever the need arises.

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 minding 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 has a good and highly fuel-efficient engine but it doesn’t have a large fuel capacity tank.

You can only put 1-gallon 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 at 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 for the USB ports where you can directly charge your smartphones and connect speakers having USB Type C connectivity.
