The Top 10 Smallest Portable Generators

Portable generators come in a wide variety of shapes and sizes. The market is full of devices which range from such that can fit on your shelf, to those which require wheels to move around. But which are the smallest?

In this article, we will focus on the smallest portable generators currently on the market. After all, portability is the reason why most people are after portable generators in the first place, be it for the lack of space in their garage, to avoid the struggle of moving around a heavy device, or so that they can fit them in their car trunk. It makes sense to look for the smallest ones possible.

However, their small size comes at a price. Most significantly, the shrunken dimensions take their toll on the generator’s wattage, fuel capacity and the number and types of available outlets. In addition, they are not always all that cheaper than their larger counterparts. Sometimes even on the contrary, as it may be actually harder to fit a well working generator with all its parts into a small, portable casket.

Many small generators are inverter generators and vice versa, most inverter generators are small. Most people will benefit from inverter generators, as they can be used to directly power any device, including sensitive electronics, but you should keep in mind that they have an inherently higher price/wattage ratio.

With that said, even the smallest generators are well equipped to preform most recreational and hobbyist tasks. The demand for them is stunning – even you came to check them out! So here they are, the top 10 smallest portable generators currently on the market!
