How Do Gasless Generators Work?

Gasless generators are also known as battery-powered generators. These generators are different from conventional generators that rely on gas, propane, or diesel to produce energy. Gasless generators work with a robust rechargeable Lithium battery. This battery contains ions that move from the negative to the positive electrode. The movements of the ions lead to the generation of electric current that is supplied to any device plugged into the generator.

Battery-powered or gasless generators don’t use fuel. They use the sun (solar panels), an electric grid (120V wall socket), or a car charger to recharge their batteries. In some cases, like Jackery Explorer 500, you can recharge the generator by hooking it to an electric generator. Gasless generator batteries recharge when ions in the battery move from the positive to the negative electrodes. As this process continues, the battery stores the energy for subsequent usage.

What Are the Benefits of Buying a Gasless Generator?

Apart from their excellent performance, gasless generators have numerous benefits to the users and environment as well. Some of the benefits include;

1. They are lightweight

Gasless generators have a compact design and come in small weight compared to the traditional generator models. This makes it easier for users to carry and store them. For instance, in our review, Westinghouse iGen300s weighs about 6.35 pounds; it is the lightest gasless generator in our review. Any adult will have an easy time lifting a 6.35 pounds generator.

2. Gasless generators are noiseless

Gasless generators operate quietly, unlike gas, propane, or diesel-powered generators whose engines have noisy operations. You can use gasless generators anywhere without worrying about their operational noise.

3. They don’t produce exhaust fumes

Since gasless generators don’t burn gas, propane, or diesel to have power, they don’t produce exhaust fumes. You can safely use them indoors.

4. They are cheap to operate

You don’t need to incur fuel costs such as buying gasoline, propane, or diesel to run a gasless generator. Provided you have solar panels, a source of the primary grid, or you have a car, you can recharge the generator for later usage. 

To enjoy the above benefits and many others, you should invest in the best gasless generator. Any of our reviewed gasless generators above are reliable. 

Factors to Consider When Settling for a Gasless Generator

Many gasless generators are reliable. However, before settling for any of them, there are critical factors that you need to consider.

Peak & Rated Power Outputs

Just like when shopping for fueled generators, starting and running power of a gasless generator is vital. Before settling for one, you should consider the appliances you intend to power with the gasless generator. If you are looking for a gasless generator for powering a few devices at the camp, Rockpals 300W and Westinghouse iGen300s are good options. But if you are looking for gasless generators for powering essential appliances at home, BLUETTI AC200P and Goal Zero Yeti 3000X generators are your best choices.

Battery Type and Capacity

best gasless generatorGasless generators operate using batteries. When shopping for a gasless generator, you need to know whether the generator runs on a lead-acid or lithium-ion battery. Among the two battery types, lithium-ion works efficiently. Additionally, lithium-ion batteries are lighter, and they are more long-lasting compared to lead-acid batteries. However, gasless generators operating on lithium-ion batteries are more expensive.

Check on the battery capacity. Battery capacity is measured by watts per hour, and it usually ranges from 200 to 5000Wh. The higher the value, the more the battery capacity. A higher capacity battery means the gasless generator will operate for longer hours than when the battery has a low capacity.

Available Power Outlets

The type and number of power outlets on a gasless generator determine how versatile the generator is. A reliable gasless generator should have at least 1 AC 120V standard house outlet, USB ports (Type A and C), and a 12V DC outlet. The more the power outlets, the more appliances you can power simultaneously.

Size and Weight

Size and weight are critical factors when looking for a portable generator. If you are an outgoing person, a camper, or an RV reveler, you need a compact and lightweight gasless generator for easy transportation. In our review, Westinghouse iGen300s is the lightest model, and it weighs about 6.35 pounds. This is a good weight for anyone looking for a light gasless generator for their moderate outdoor power demands.


A reputable gasless generator brand comes with a warranty cover. The warranty policy may range from 1-5 years, depending on the manufacturer. The warranty cover means you can use the generator and get free repair services or a unit replacement if the generator malfunctions within the warranty policy period. All gasless generators in this review have at least two years warranty.

Faqs About Best Gasless Generators (Battery Powered)

1. Are there Non Gas Powered Generators?

Yes, battery-powered generators, also known as gasless generators, do not operate on gas, propane, or diesel. Gasless generators have lithium-ion batteries recharged either through an AC wall socket, solar panels, or a car charger. These generators operate quietly and have no emissions since they do not burn fuel.

2. Are battery-powered generators any good?

Battery-powered or gasless generators are great power solutions for a temporary power outage. Or, when you need power and cannot access gas, propane, or diesel, a gasless generator comes in handy. However, battery-powered generators are expensive and cannot run for longer hours compared to conventional generators.

3. What can I power with a gasless generator?

best gasless generatorDepending on the power output of your gasless generator, you can power a wide range of electrical appliances. For instance, most gasless generators in our review can power CPAP machines, TVs, fans, lights, and heaters for the powerful models. When buying a gasless generator, ensure you buy one that can meet your power demands. 

4. What is the most powerful battery generator?

Dory B7000 is the most powerful battery generator in the market today. This generator has a peak wattage of 6000W and 3000 running watts. In our review, BLUETTI AC200P is the most powerful gasless generator with a starting power of 4800 watts and rated wattage of 2000 watts.

5. Can a solar generator power a house?

Yes, if you have the right solar generator, you can power your house. For instance, our review reviews the Goal Zero Yeti 3000X solar generator as the best generator for home use. The generator has a high power capacity to power essential household appliances should there be a blackout.  

6. How long can a solar generator operate?

The battery capacity of a gasless generator, current charge level, and existing load determine how long the generator can run. Typically, a gasless generator can operate from 1-10 hours.

7. Can a solar generator run a space heater?

best gasless generatorMost space heaters are rated 1500 watts. Any solar generator with a power output of more than 1500 watts can power a space heater. BLUETTI AC200P, Duracell PowerSource 1440W, and Goal Zero Yeti 3000X are some of the solar generators in our review that can run a space heater.

8. Can a generator battery explode?

Yes, excessive charging of generator batteries can lead to their explosion. Normally, when batteries are charging, they produce gas. When the tiny battery ventilations are blocked, the batteries are likely to explode. 

9. Can a solar generator battery explode when overcharged?

Lithium batteries can overheat and explode when they are overcharged. Therefore, you should avoid overcharging your solar battery. Besides overcharging, ensure the battery is in the best condition.

Final Verdict

Investing in the best gasless generator for your home or outdoor power demands is one of the rational decisions you can make.
