Buyer’s Guide

To buy this best Rockpals generator, you have to keep in mind the following things.

Type of Generator

What type of generator do you need? If you are a hiker, explorer, or love doing camping, then the Rockpals solar-powered stations are made for you. They are ideal to power small appliances and electronics that you may need to make your trips interesting and memorable. Also, you can use them during power outages or to power your essentials at home and office.

If we talk about inverter generators, then they can power small to mid-size appliances as well as electronics. Inverters also produce clean power, which is ideal for running delicate electronics. But to power your whole house, an RV, or power-packed tools, you just need a conventional generator with higher power output.

Factors to Consider when Buying Rockpals Solar Generators

Power Output

Different solar models give different power outputs. Rockpals 300 produce 600 surge watts and 300 rated watts. It means you can run all those devices that need less than 300 watts of power to run or charge. On the other hand, Rockpals 500 allows you to power all those items that are rated below 500 watts.

So, the selection of the generator depends on the type of devices you have. If 300 rated power is enough for your devices, select Rockpals 300; otherwise, Rockpals 500 is the best choice.

Battery Capacity

Rockpals 500 battery is more powerful and has higher power-storing capacity so it can bear more load and run your appliances and electronics for longer than the Rockpals 300-watt generator.

Solar Panels

Rockpals solar generators don’t come with solar panels, so you have to buy them separately. If you only need a generator for smaller outdoor activities, then you can ignore buying a solar panel. Charge your battery via an AC wall outlet or a carport and enjoy your gatherings. But solar panels come in handy when you are on an off-grid trip, and due to some reasons, you are forced to extend the duration of your trip.

For Rockpals 300, you can either go with a Rockpals 60-watt or 100-watt solar panel and for Rockpals 500, it is suggested to use the Rockpals 100-watt solar panel.

Factors to Consider when Buying Rockpals Portable Generators

Power Output

List down all those things that you need to power through your generator and add their watts. The total number of watts will help you to get the best suited portable generator.

If we talk about Rockpals portable generators, then we have only two options available. One is the R2000i that produces 2000 peak watts and 1800 rated watts. And the second one is Rockpals 12000, which is a dual fuel generator. It delivers 9000 rated watts on gasoline, and 8100 rated watts on propane.

So, if you only need small or mid-size appliances to power, select R2000i. But to run your whole house or tools at a construction site, use Rockpals 12000.


Inverter generators make a less operational sound than conventional generators. Rockpals R2000i creates only 58dB noise at full load, whereas Rockpals 12000 creates 78dB noise.

If you are going with an inverter generator, then its noise rating is ideal for you. But if you need a powerful generator, then make sure you are more than 7 meters away from the unit.


Runtime depends on the tank capacity and fuel-efficiency of the engine. Also, the amount of load changes the runtime.

Rockpals R2000i has a smaller fuel tank of 1-gallon, but because of the eco-mode, it gives higher runtime. On the other hand, Rockpals 12000 has a much bigger fuel tank of 6.6 gallons, so it also gives higher runtime, but because it has a powerful engine, its runtime and R2000i runtime is almost the same.


Both the Rockpals portable generators come with a safety feature to keep the engine and your equipment and appliances safe and protected.

Rockpals 12000 comes with a surge protector and automatic low-oil shutdown. And the R2000i model has overload protection and low-oil shutdown features.


What kind of oil is recommended to use in Rockpals portable generators?

You can either use 10W-30 or 15W-40 motor oil to keep the engine running in a good state.

Which CPAP machine can Rockpals 500 generator power?

It supports CPAP machines with less than 96-watt rated power.

Can I use two 100-watt solar panels to power Rockpals 500?

The Rockpals 100-watt solar panel is not parallel capable. You have to buy two 80-watt solar panels to power your Rockpals 500. But if you need a 200-watt solar panel, you can go for other brands.
