Top 10 Smallest Portable Generators

Portable generators are perfect for when you need power on the go, and they’re available in a huge range of shapes and sizes to suit pretty much every need.

Whether you’re camping or tailgating, having a generator to power your small devices can keep you connected. 

The majority of people won’t require the monstrous generator units found on worksites, and you’ll have all the power you need with a more compact, lower-wattage generator which you can easily transport from place to place to suit your needs.

Top 10 Smallest Portable Generators

One slight problem is that size is subjective, and what one person may find small might be too big for another person’s purpose, so it’s hard to quantify this.

There’s also the cost to consider, as bigger and more powerful tends to mean more expensive too. We’ve included a range of generators from a budget of $129.99 to $479.00 to try and cover all bases. 

In a hurry?

Top 10 Smallest Portable Generators Buying Guide

How Much Power Should You be Packing?

Either limited space or the need for portability already dictates that you need a small-sized portable generator, but you can still choose from a range of wattage outputs. In general, the lower the wattage the smaller the generator will be, but there are some exceptions to the rule. 

So how much power do you really need? The answer will depend on the number of devices or small appliances that you’re planning to power. If you write down a list of the typical things you’ll be charging and add them up to get a total wattage you’ll have a good guide. 

You can base your decision around this number, but leave yourself a little bit of leeway and go slightly higher so that your generator isn’t constantly running under a full load. 

Frequently Asked Questions 

How do portable generators work?

Portable generators run on a gas-powered engine that generates electricity via an on-board alternator which you can then use to power your devices and appliances.

You do this by plugging an extension cord into one of the available outputs, although the exact ones depend on the generator you choose as more powerful units typically have more options.

What size generator do you need for camping?

The answer to this question depends on how much equipment you’re taking.

If you mainly want a backup power source to charge your small devices a few times during the trip then a small, low-wattage portable generator will be sufficient, but if you want to run larger appliances like your television, constant lighting, heaters, fans, and mini-fridges you’ll need to look for something above 300 watts.

Can a portable generator run all day?

Most small portable generators can run for a minimum of 5 to 8 hours when fully charged, and some of the higher-end units allow you to re-charge the generator’s battery whilst still charging or powering your devices.
