Engine and run time:
The Generac GP 3000i has a 149cc engine which is notably bigger than GP 2200i, which has 80cc displacement. Since Generac GP 3000i has a bigger engine, it gives you 2200 running watts which can power many appliances and tools, than Generac GP 2200i, which has 1700 running watts. Running watts are the continuous watts that keep the items running, and both the generators can juice up household appliances.
The gasoline consumption of GP 2200i is 0.11 GPH (gallon per hour) and GP 3000i is 0.18 GPH (gallon per hour). So in terms of gas consumption, Generac Gp 2200i is more fuel-efficient than Generac GP 3000i though both are inverter generators that are more fuel-efficient than traditional fuel generators. The Generac GP 2200i also offers you 10.75 hours of runtime at 25% load capacity, which is higher than Generac 300i, which offers you 5.8 hours of run time at maximum capacity. So when it comes to fuel efficiency and run time, Generac GP 2200i has the edge over Generac 3000i.
Generator outlets:
The Generac GP 3000i has more AC receptacles than GP 2200i. The GP 3000i has three AC outlets, whereas GP 2200i has only two AC outlets. So you can power two devices at the same time. These generators do not have GFCI (ground fault circuit interrupter), which could be problematic because GFCI prevents electrocution. But since it has inverter technology, you need not worry about electrocution as long as you use them in a safe environment. Both the generators come with a DC outlet, and both produce 120V. They both offer low THD (total harmonic distortion), which is less than 3%, so they are suitable for powering any sensitive electronics like mobiles, laptops, etc.
Warranty:
When you are buying a generator, the generator's warranty period is important. Generac generators have excellent customer support, and they provide reasonable warranty periods too. The Generac GP 2200i gives you two years limited residential warranty and one year limited commercial warranty.
