Now that we have presented the seven dual-fuel generators, how do you choose the right one for your needs? This buying guide will summarize some important factors to consider before choosing a dual fuel generator.
These are as under:
Your power needs
The amount of energy will determine the generator that you need. Check your device and decide what type of dual generator will fit you. If you only have a few essential tools, then probably you do not need a lot of energy. You, however, need a high power generator if you plan to use your generator for your entire household power needs.
Portability is an important factor, especially if you plan to use your generator for outdoor events. Some generators will have integrated mobility kits, while in others, they come as accessories. Check their functionality to ensure they are rugged enough to withstand the weight and can work on any terrain. The handles should have soft grips for comfort and more accessible storage.
We measure noise and sound in a unit called decibels (dB). The higher the number, the louder the generator is. The generators are noisy machines, but some models operate at a much calm level. We consider a dual fuel generator with 60 dB or below a perfect choice for campers or use in close quarters.
Types of ignition
Dual fuel generators will have different starting systems for both gasoline and propane. For gasoline, most models have a former recoil system, and some ignite electrically. Propane ignites electrically with a turn of the key. So when calamity strikes, choose the fuel you prefer, or that is available to turn on the system.
Monitors and indicators
Any generator must provide the correct information about the oil levels, fuel levels, and the general status of the unit. Most dual fuel generators have integrated different styles of monitoring, including LED displays and indicator lights. The indicator lights help to monitor the engine oil level, engine overload and preparing the generator all at a time.
Since it is a personal mini electric power station, you should be sure they have put several safety systems in place before you operate your generator. A good model should have overheating protection, protection against overload, and low oil shutdown mechanism. All these systems will keep you safe and keep your generator working smoothly.
