Best Affordable Portable Generator Buying Guide

Okay, so we’ve found you some generators that won’t quite break the bank (although we’re not denying they’re still a considerable investment, even at the more affordable end of the spectrum). What else do you need to think about to make up your mind? 


Size / Portability

The key is in the name, right? If it ain’t compact, it ain’t portable, so you want a space-saving generator that’s able to easily fit in the trunk of your car and won’t throw your back out when you’re unloading everything.

Ranging from under fifty pounds all the way up to several hundred, you want a machine you’re actually able to carry safely - what if you had to pack up and leave in a hurry? You don’t want to abandon hundreds of dollars of equipment!

A soft-touch handle is always a nice addition, too, as it will make carrying from car to campsite a whole lot easier: some generators even have wheels on the bottom, though these are usually at the pricier end.

Power Source

You’ll find there are several different fuels for generators, perhaps the most popular being gas, typically propane or natural, burned by a motor with fumes released via an exhaust pipe at the back - their run time depends on how much gas you have!

Another popular, more contemporary power source is solar panels, which of course add some bulk to the machine and increase its size and weight, but prove much better for the environment after continuous use in the long run.

You can also find generators that are powered by a gigantic rechargeable battery, though of course you’ll have to keep this plugged in and charging up for a significant amount of time before you can even switch it on, never mind use it fully.


Our intention here is to provide you with affordable and portable options for generating power, which means that they aren’t going to be as supercharged as some of the bigger and more expensive options out there.

However, it’s still possible to get a substantial wattage on a smaller, sleeker generator, enough to power all of your camping gear or the most important and essential household appliances in the event of a surge or outage.

For a house, 3000 and 5000 watts is a good aim, as this should be able to cover all of your basic needs and then some, whether you’re indoors or outdoors.

When you need to, for instance, pump your own water, more power is required.


It doesn’t matter if you’re roughing it in the great outdoors or your portable generator is kept in the basement, only coming out for emergencies: you want one that’s going to last, and that means a well-built machine made from quality materials.

Whether that’s the exhaust pipe, the control panel or the casing of the battery itself, if it’s not been built well, it won’t be able to stand up to the tests of time or take the beatings that Mother Nature can sometimes offer out.

Waterproofing is another consideration when you’re camping; though it’ll be pretty difficult to find a generator that’s entirely hydro-resistant, looking for a model that’s going to withstand more unpleasant weather conditions is your best bet.

Continuous Run Time

In a power outage, it’s pretty difficult to guess how long you’re going to need your generator for: could be twenty minutes, could be two days.

To prevent your freezer from melting and avoid sitting in the dark, a long enough run time is essential.

Some generators can only go so long before they need some more juice, whether that’s gas, solar power or a recharge from the outlet, but others will need a rest to avoid overheating, regardless of how much power they have left.

Quality portable generators can last several days, provided they aren’t running at full power or providing watts to too many sources, but we’d recommend between 7 and 12 hours of continuous runtime at minimum to get the biggest bang for your buck.


We’ve already written quite an extensive piece about how to reduce the noise of your generator - unfortunately, as they’re producing power for you, they’re also making quite a racket in the process, which can be anything from irksome to heinous.

More contemporary models have usually been fitted with inversion technology, which uses magnetism as part of the power production process, reducing the noise produced by the motor as it burns through fuel.

Likewise, higher-quality manufacturers will also make sure their generators have been equipped with noise cancelling features like ventilation ducts and a quality exhaust pipe, which helps minimize the background sounds significantly.

Extra Features

So long as the generator you choose ticks all of the above boxes, you’ll be good to go, but if you’re after some additional fun and flair, you may be intrigued by the following add-ons some models have built in.

An LED flashlight is an especially useful provision, particularly if you’re looking at using your generator at night, in the middle of the woods, or expecting to experience plenty of power outages. You’ll free up a hand as well - no more using your phone!

More modern devices tend to have USB ports, for instance, which allow you to plug in and charge your smart devices amongst other things and free up outlets for more important appliances, like your cooking equipment!

Frequently Asked Questions

Should I get a portable or standby generator?

That depends on your circumstances! A standby generator is powered by natural or propane gas and will kick in automatically as soon as a power outage occurs, making them a semi-permanent fixture that you can keep on standby. Get it?

Portable generators are either powered by diesel, gas, solar power or a huge rechargeable battery, and they’ll typically be much cheaper than a standby generator, but won’t start up autonomously.

How much wattage do you need to run a house?

Obviously everybody’s home is different, and we all have different appliances and equipment to run, so it’s difficult to pinpoint exactly what wattage you’re going to need personally in order to run your home.

A general estimate suggests that critical household electrics like a refrigerator, freezer, lighting and heating, even a well-pump, can manage with between 5,000 and 7,5000 watts, potentially at the same time depending on each appliance’s demands.

If you want to be able to power absolutely everything in your home, the easiest and most successful way is to manually calculate the wattage of all of your appliances and buy a generator with enough power to run them all.

How can I make my generator sound quieter?

As we’ve discussed, whilst generators are incredibly useful, they can also be loud enough to disturb you when running, producing a rumble or buzzing sound that is difficult to block out at the best of times.

Luckily for you, we’ve already covered a myriad of methods to reduce or quieten the harsh grumbling generator in a previous article, which you can check out here.

You’ll find some quick tips and a full guide to building your own soundproofing box.
