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?
Page Content
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!

DC output | Yes |
Given its approximate dimensions of 14 x 9 x 13" and its light weight of 23 lbs, the Lifan ESI 860i-CA is the smallest of all the portable generators in our database. These small dimensions make it particularly well suited when you want to generate power on-the-go, bring it on a camping trip, or do some small DIY tasks.
Its 40 cc, OHV 4-stroke, Lifan engine can deliver up to 600 running watts and 700 starting watts. It offers 3 hours of run time at 50% load, which is a relatively deceiving value, when compared to other units of similar power. However, this low runtime still is perfectly suitable if you find yourself in a short power outage or have a small job to do. Its noise emissions are average for its power, as its sound level at 23 feet can be as low as 58 dB (less noisy than a conversation at home).
Its control panel offers 1 AC outlet (NEMA 5-20R), as well as a 12V receptacle to let you conveniently charge your batteries. Because it's an inverter generator, its low THD (<2%) allows you to safely plug in any appliances with sensitive electronic components (laptops, mobile phones, etc.).
The unit is CARB-compliant (which means it can be purchased in any of the 50 states). It can also be operated without any worries, as it features a low oil sensor, which prevents engine damage and circuit breakers, which prevent overload.
The price of this model is average, when compared to similarly-powerful units.
