How did we choose the Best Portable Generators Under $500?
A portable generator can be handy as an emergency solution in the event of a power failure at home or to operate devices away from a source of electricity. However, you must be able to calculate your electricity needs and know the existing technologies.
Today there are several types of generator sets. What sets them apart is their energy source:
- Gasoline generators: these are the most common. They generally run on Unleaded 95 or 98. Their main shortcoming, however, is the emission of exhaust gases. It is entirely inadvisable to use them in an enclosed space. Nevertheless, they are very simple to use, very safe and have the advantage of being smaller.
- Diesel generator sets: generally similar to the previous ones, they are typically distinguished by better autonomy. Their main advantage is that diesel expires even slower than petrol. This is an advantage for a backup generator in the garage. Generally, more powerful, they are used more in professional and industrial environments.
- Gas generator sets: since they do not produce exhaust gases, they are not harmful for indoor use. But you can imagine, a gas bottle with a certain weight (at least 30 kg for standard butane). It is not advisable to buy a generator set using only gas, especially since they are difficult to find. But investing in a hybrid model can be a good plan to ensure its versatility.
- Solar generators: with a yield of around 35% at present, this technology is the future. If the solar chargers can be enough to charge your phone in a few hours, it will not be the same on a construction site.
After defining your needs in terms of power and place of use, here are other characteristics you can rely on to make your choice:
- Energy consumption: location (campsite, construction site, etc.) and use determine the power required. The amount of current (expressed in watts) required will depend on the type and number of devices you want to connect to. However, be careful always to provide a small margin (about 200 W), since some devices consume more at launch than in their continuous use.
- Wattage: this criterion depends on your needs. When camping, you are going to need around 2000 W, especially if you have a motorhome (with lights and appliances). 1000 W is enough to cover everything related to smartphones, lights, and computers. The rest can cover the kitchen consumption, provided you do not light everything at the same time. If you use 100% of your generator’s capacity, you will use it twice as fast. Have a 25% margin.
Knowing this, we analyzed a series of characteristics to decide between the five models that we had selected based on the first criteria:
- The fuel consumption or yield: for occasional use, this is not very important. But if it is for use over a week of vacation, for example, analyzing the performance becomes interesting. Prefer generators that adapt their consumption to the wattage consumed.
- The noise level: the models can differ significantly on this point, but again it all depends on your use. For a campsite, it will be necessary to pay more attention to the noise generated. One of the prerequisites is to look for a portable model that runs as quietly as possible or to buy extension cords to keep you away from the noise.
- Autonomy and capacity: if the displayed autonomy is only 5 hours for 15 L of petrol, it is a poor performance. If you want to buy a generator set as an emergency solution during a natural disaster, for example, invest in a model that offers maximum hours of current with a full tank.
- Ease of use: some models automatically calculate the voltage according to the connected devices, with a voltage regulator or an Inverter. Among the other little features that make life easier for amateurs is an automatic start. However, check that this type of model also has a manual start, in case of an emergency.
- Ease of maintenance: an oil level gauge is a must to avoid smoking up all the space and an emergency stop system if no more oil can still be useful.
- Ease of transport: remember that the weight of a generator is not necessarily linked to its power, but that a power generator is often heavier. The weight indicated on the technical sheets does not include fuel. Ideally, prefer a model with wheels included (good quality and all-terrain).
- The rotation speed: This is the revolutions that the engine manages to turn within a minute; this measurement is given by the RPM. Traditional 60 Hz power generators work by reaching a rotation speed of between 1800 and 3600 RPM while decreasing in power to 50 Hz; the speeds have a range of between 1500 and 3500 RPM. The first category includes the most sophisticated engines that can reach necessary measures; they are industrial mold machines, indicated for intense and continuous use over time. The second category, on the other hand, refers to smaller engines that do not require too rigorous maintenance and can be used for trips outside the city or for small energy events.
- Inverter technology: The other factor in question regards the frequency stability, which is the frequency fluctuation linked to the motor. The advice is to choose a fluctuation that settles on ± 0.5 Hz. If there is a need to power electronic devices, proper clarification must be made. This feature could damage an electronic device if it is connected. To overcome this problem, generators are equipped with an Inverter technology, which therefore manages to stabilize the quantity of electricity supplied.
By considering all these characteristics, we established a list of relevant models from reliable brands. We then consulted many user reviews on dedicated sites, blogs, YouTube channels, etc. This allowed us to present to you, in the end, the five best generators under $500.
