Features: Rainier R2200i Portable Generator

Type of Generator: Rainier R2200i is an inverter generator. It runs on gasoline to power your essentials at tailgates and campgrounds. Also, it can be used at home, job site, or for emergencies.

Warranty: It offers a 3-year limited warranty. A limited warranty means it doesn’t cover all parts of the generator.

Engine and Power Output: It is powered by a 79cc, 2.7 HP 4-stroke OHV engine, which delivers 2200 starting watts and 1800 running watts.

Rainier R2200i produces clean power, thanks to its less than 3% THD (Total Harmonic Distortion) rating.

Clean power is always suitable for sensitive electronics so you can power your smartphones, laptops, tablets, and other electronics without any fear.

Parallel Capability: The best thing about this generator is that it is parallel capable. All you need is a parallel kit to connect another Rainier R2200i with this unit. This will help you to get 4400 starting and 3600 running watts.

What it can Power: Before powering any appliance, check its starting and running power to make sure it is under the generators’ power generation capacity.

If you have big appliances to run, you can power one or two at a time. But if you only need to power small appliances and electronics, then you can power multiple at a time.

Fuel Capacity and Runtime: At 25% load, Rainier R2200i gives up to 13-hour runtime on a 1.3-gallon gasoline tank. Its fuel consumption is around 0.1 gallons per hour.

It is also equipped with an eco-mode that reduces the engine speed to match the current load demand. This not only saves fuel but also safeguards the engine from wear and tear.

Starting Mechanism: Rainier R2200i comes with a recoil start system. It even starts easily in cold weather with the help of a choke button.

Noise Level: You can use this generator at campgrounds, parks, and tailgate parties without disturbing yourself and the neighborhoods. It operates quietly at 52 dBA.

Power Outlets: Its power outlets include two 120 Volt 20 Ampere (5-20R) household receptacles and one 12 Volt DC outlet for charging batteries.

Light Indicators: Three light indicators tell you the status of your generator. When it starts to bear the extra load, the overload indicator turns on. The low-oil indicator shows the oil is at a minimal level. And the output ready signals that your unit is ready to take the load.

Safety Features: Low-oil shutdown and overload protection safeguard your equipment from damage.

Emissions: Both EPA (Environmental Protection Agency) and CARB (California Air Resources Board) certifications allow it to ship and use in all 50 states.

Portability: Rainier R2200i is extremely portable, weighing only 44 pounds. Its length is 19.7 inches, its width is 13.3 inches, and its height is 17.3 inches. It also features a handle for stress-free movement.

Cons: No USB port is there. Also, its build quality is not up to the mark.


Does Rainier R2200i come with an extension cord?

Rainier R2200i doesn’t come with an extension cord; you have to buy it separately. Make sure you are purchasing a cord that is compatible with R2200i.

Can I connect Rainier R2200i with another brand of inverter generator?

Yes, you connect an inverter generator of a different brand. There is no problem with doing that. But make sure the cord is compatible with both inverter generators. Also, the power output of the other generator must not exceed what the cord can handle.

Which oil should I use for Rainier R2200i?

It uses SAE 10W-30 engine oil. It is the best engine oil for normal climates.
