Revealed: Best generators for your 4WD adventure

If you've got a 4WD, you're no stranger to using your car battery and alternator to power up your 12V accessories. But when you're on a big 4WD adventure, you need a trustworthy power source you can rely on to keep you powered up for days on end. Here we reveal the top three generators on the market.

Generators are great for portable 240V power and for recharging your battery packs

Before we get to the good stuff, let's look at the benefits of using a generator on your 4WD adventure:

  1. Convenience: You can power most of your camping equipment like fridges, lights, television and other forms of electrical equipment without killing your 4WD's battery.

  2. Emergency charger: The most common use for a camping generator is recharging your deep-cycle battery packs (via a battery charger), which run all your creature-comfort 12-volt appliances.

  3. Lightweight: Camping generators are built to be lightweight and compact, so they're easy to move from vehicle to campsite and back again.

  4. Quiet: These days, generators are built with sound muffling features so you don't need to worry about disturbing the neighbours - human or animal.

  5. Fuel Efficient: today's camping generators are inverter generators. Meaning they not only produce the cleanest power, but they also adjust their fuel consumption according to the load required so you maximise fuel efficiency.

Here's our pick of the best 4WD generators for your next adventure:

1. The Yamaha EF1000iS

Yamaha produce the quietest and lightest camping generators in the market, making them extremely popular in the 4x4 world. At only 12.7kg, the Yamaha EF1000iS it's the lightest 1000 watt portable generator you can buy. Plus it only produces a super silent 50 decibels of noise at normal operating levels - again, lowest in its class. It's market leading smart throttle is extremely accurate and automatically adjusts the engine speed to maximize fuel efficiency. At a quarter load, you will get an impressive 12 hours of power before having to top refuel! This model is one of the most popular by 4wd enthusiasts, particularly as a back option to solar for recharging battery packs. You can see how it stacks up to its Honda 1000 watt generator counterpart in this article here.

2. Yamaha EF2000iS

You knew it was coming - the Yamaha EF2000iS is the number one generator for your 4WD road trip. If you want a backup in case your starter battery goes flat, as well as have the extra power to directly run your favourite camping appliances, this generator is your best choice. Even though it produces a maximum of 2000 watts, it is famously quiet, producing only 52 decibels thanks to that Yamaha Noise Block Sound Reduction System. This makes it the quietest generator in it class.

This generator features inverter technology so power produced is pure and without fluctuation - perfect for sensitive electronics. It's also incredibly fuel-efficient like its little brother thanks to the Yamaha Smart Throttle. And if your mate has the same generator, join them together for almost double the output when you're out on the road!

3. Cromtech CTG2500i

Known for its value for money, Cromtech generators are a great option. The Cromtech Outback 2400W model is the most popular budget generator for 4WD trips that don't require frequent generator use. Coming in at under $1000, you might expect the unit to be missing some key features, however, that is not the case. This unit has everything you would expect in a generator, such as great fuel economy, 2 x 15 amp outlets, USB charging outlet, low oil, and over load protection. Crommelins back their products with twelve-months warranty, support by a nationwide service network. This sets the unit apart from other Chinese manufactured generators, which is very compelling for a budget brand.
