Fuel
The type of fuel that the generator's engine runs on.
—
Gasoline. One of the main types of fuel for internal combustion engines. Gasoline generators are usually cheaper than diesel generators, all other things being equal, but they are more expensive to run due to the higher price of gasoline; in addition, they usually have a shorter resource than diesel ones. Therefore, it is believed that gasoline generators are well suited primarily as a backup power source in case of a power outage.
—
Diesel. Diesel generators are usually more expensive than their gasoline counterparts; on the other hand, diesel fuel is cheaper than gasoline, so the increased cost may well pay off with regular use. In addition, diesel generators have a longer resource and a larger power range than gasoline ones. This allows them to be used as both backup and main power sources, including at rather "energy-intensive" objects.

Gas. The advantages of gas-fired generators are relatively low noise levels and low emissions. On the other hand, the use of gas as a fuel is associated with certain difficulties: it is necessary to connect to a gas pipeline or regularly replace special cylinders, the fuel system is especially sensitive to leaks, etc. Therefore, there are relatively few such models produced, and most of them are stationary high power generators, in which the menti
...oned disadvantages are covered by the advantages.
- Gasoline / gas. Models capable of using both types of fuel indicated. This gives the user the opportunity to choose the option that best suits a particular situation, and also reduces the likelihood of being left without fuel at the most inopportune moment; on the other hand, such models are more expensive than single-fuel ones. The technical features of gasoline and gas are described in detail above.Output 12 V
Existence in the generator of an
output with a direct current and voltage of 12 V. The main function of this output is to charge car batteries, as well as power devices originally intended for cars (recall, 12 V is the standard voltage of on-board networks in cars).
The following types of 12-volt outputs are found in generators:
- Terminals. Terminals are used to connect wires directly without using any plugs. This connection is the most reliable.
- Socket. Socket outlet for a plug with two flat pins, designed to connect 12-volt consumers. Holes in sockets come in different layouts, which you need to pay attention to.
- Cigarette lighter. The so-called "car socket", which in many cars is combined with a cigarette lighter socket (hence the name). Such connectors are used to power various automotive devices and accessories.
Weight
The total weight of the unit - as a rule, excluding fuel; The full fill weight can be easily determined by knowing the tank capacity.
In general, more powerful generators inevitably turn out to be heavier, but models with similar characteristics can differ noticeably in weight. When assessing these differences and generally choosing an option based on weight, it is worth taking into account the specific application of the generator. So, if the device will often be moved from place to place - for example, when used “on the road” - it may be worth paying attention to lighter units that are more convenient to transport. However, it is worth considering that the downside of a lightweight design is often an increased cost or a reduced degree of protection. But for stationary use, you can not pay much attention to this parameter - or even the opposite: choose a heavier (and, as a rule, more advanced and functional) option.
Regarding specific numbers, it is worth noting that modern generators in general are quite massive. So, a small weight for such equipment is considered not only
up to 20 kg, but even
20 – 30 kg ; Many units weigh
150–200 kg, or even
more, and the weight of stationary industrial models is already measured in tons.
