What Size Generator Do You Need For Camping?

November 7, 2025 | Nate Cord

Escaping into the great outdoors doesn’t mean you have to leave all the comforts of home behind. Whether you’re heading out for a solo adventure or a family camping trip, having access to electricity can make a world of difference.

A reliable generator can power your morning tea, charge your devices, or even run a small fridge. It can help you enjoy the modern conveniences you’re used to, without compromising the freedom and fun when camping.

So, how do you know what size generator you need for camping? The answer depends on the type of camping you’re doing and the equipment you plan to run.

In this guide, we’ll break down how to choose the perfect generator size for your camping setup.

Assess Camping Power Needs

Planning your power requirements before a camping trip is key to avoiding unexpected problems and ensuring your devices run smoothly.

Start by making a list of all of the equipment you’ll want to use, from small appliances like a blender to phones, tablets, or a mini fridge.

Next, note the wattage of each device. For example:

• Travel kettle: 800 W
• Phone charger: 20 W
• Small stove: 50 W

Add them together to get the total power requirement: 800 + 20 + 50 = 870 W. Then, it’s smart to include a safety margin of around 20% to cover any extra usage or fluctuations, bringing the total to about 1,044 W.

Based on this calculation, a generator in the 1,100–1,500 W range would be ideal to safely power these devices and cover any additional needs.

You can use our generator power calculator to make this process even easier. Simply enter the appliances and devices you plan to run, along with their running and starting wattages, and the calculator will estimate the total power your generator needs.

Carefully assessing your power needs before heading out is essential to prevent surprises and ensure all your devices operate smoothly.

Review Starting and Running Wattage

In addition to the steady power a device needs, you also need to account for the starting wattage, which is the brief surge of power required to get certain appliances running.

For example, a small fridge might require 800 W to operate continuously (running wattage) but could need up to 1,600 – 1,800 W when first starting. Similarly, a microwave rated at 1,000 W could demand nearly double that in the first few seconds.

How to calculate:

• Running Wattage: Volts x Amps – this is the continuous power a device uses.
• Starting Wattage: Volts x Starting Amps (often about 2-3 x running wattage) – this covers the initial surge when devices turn on.

Knowing running and starting wattage will help you choose a generator that handles the constant power draw, as well as the brief spikes that occur when appliances start. This ensures your appliances or other motor-driven devices turn on without overloading your generator.

Small Generators for Basic Camping Setups

A small generator is usually sufficient for light camping trips where power needs are modest.

Typical requirements include charging phones, powering small speakers, or handling essential kitchen appliances. In most cases, a generator with 500 – 1,000 watts of output will cover these basic tasks.

The Clarke IG950D 800W petrol generator is a great option for this scenario. It provides reliable, continuous power while remaining lightweight and portable, making it easy to take along on camping trips.

Its sine wave technology delivers stable electricity, making it safe for charging sensitive devices like tablets or laptops. It also has an eco mode which adjusts engine speed to match the load, improving fuel efficiency and keeping noise levels low, perfect for a peaceful campsite.

Medium Generators For Higher Power Needs

For campers who need a bit more energy, such as running multiple appliances in a caravan or powering larger electronics, a medium-sized generator is the ideal solution.

These units usually provide 1,000–2,000 watts, enough to keep fridges, lights, and other essential devices operating smoothly at the same time.

A strong option in this category is the Ford FG2500iS 2kW Petrol Inverter Generator. Offering a rated output of 1,700 W and a peak of 1,900 W, it delivers consistent power for all your moderate camping needs.

Its inverter system ensures a clean, stable supply of electricity, while its lightweight, compact design and multiple output options, including 230V, 12V DC, and USB ports, make it easy to transport and versatile enough to power a variety of devices.

Large Generators for Substantial Power Needs

For campers with high power demands, such as off-grid adventures or extended stays, a large generator is essential.

These generators typically deliver 2,000 watts or more, allowing you to run multiple high-demand appliances at once, like air conditioners and heaters to microwaves, fridges, and entertainment devices.

The Hyundai HY4500SEi is an ideal option for these situations. With a maximum output of 4,000W and continuous power of 3,800W, it provides plenty of energy to power several devices simultaneously without compromise.

The HY4500SEi is a compact generator with folding and soft-grip handles and sturdy wheels, making it easy to transport even over rough terrain.

In addition to power, it’s built for quiet, efficient operation. At 50% load, it runs at around 59dB, about the noise level of a normal conversation.

The Hyundai HY4500SEi is a powerful generator capable of running multiple high-demand devices on extended trips.
