Batteries & Generators

For camping and caravanning, the best batteries are deep-cycle AGM or lithium batteries, as they provide steady power for long periods and can handle repeated charging and discharging. Portable generators—either petrol, diesel, or inverter types—are ideal for running larger appliances or recharging batteries when solar isn’t available. Inverter generators are quieter and more fuel-efficient, making them popular for campsites. When choosing, consider your power needs (lights, fridge, CPAP, devices), the size and weight of the unit, and the noise level. For caravans, a combination of a deep-cycle battery bank and a compact generator offers flexibility, ensuring you have backup power for both essentials and comfort items, even when off-grid.

Start by listing all the devices and appliances you plan to run, noting their wattage or amp-hour requirements. Add up the total daily energy consumption in watt-hours (Wh) or amp-hours (Ah). For batteries, choose a capacity that covers at least 1.5–2 times your daily needs to allow for cloudy days or unexpected use. For generators, select a model with a rated output slightly higher than your maximum expected load. Remember, starting certain appliances (like fridges or pumps) requires more power than running them. If you’re unsure, consult the product specs or ask our team for personalised advice to ensure you have enough reliable power for your adventures.

Lithium batteries are increasingly popular for outdoor and caravan use due to their lighter weight, longer lifespan, and higher usable capacity compared to AGM or lead-acid batteries. They can be discharged more deeply without damage and recharge faster, making them ideal for frequent use or solar setups. While lithium batteries have a higher upfront cost, their longevity and efficiency often make them more cost-effective in the long run. AGM batteries, however, are still a solid choice for occasional use or as a budget-friendly backup, as they are maintenance-free and perform well in most conditions.

Always operate generators outdoors in a well-ventilated area, away from tents, caravans, and enclosed spaces to prevent carbon monoxide buildup. Place the generator on stable, level ground, and use the correct fuel as specified by the manufacturer. Never overload the generator—check the total wattage of connected devices and stay within the generator’s rated output. Use heavy-duty extension cords rated for outdoor use, and keep cords away from water or high-traffic areas. Turn off and cool the generator before refueling. Regularly check oil and maintenance requirements, and store fuel safely away from heat sources.

Yes, solar panels are a great way to keep your batteries charged, especially for extended off-grid trips. Most deep-cycle batteries can be charged with solar panels using an appropriate charge controller to prevent overcharging. Portable solar kits are easy to set up and can be used alongside generators for a hybrid power solution. While generators provide quick, on-demand power, solar is silent, eco-friendly, and ideal for topping up batteries during the day. Combining both ensures you have power even in cloudy weather or when you need to run high-wattage appliances.

Battery runtime depends on its capacity (Ah or Wh) and the total load you’re running. For example, a 100Ah battery running a 5A fridge will last about 20 hours before needing recharge (100Ah/5A = 20h), but real-world factors like inverter losses or temperature can reduce this. Generator runtime depends on fuel tank size, load, and efficiency. Most portable generators run 6–12 hours on a full tank at 50% load. Always check product specs for estimated runtimes, and remember that running at lower loads extends both battery and generator life.

AGM and lithium batteries require minimal maintenance—just keep terminals clean and check voltage periodically. Store batteries in a cool, dry place and recharge them every few months if not in use. Generators need more attention: check oil and air filters regularly, run the generator every few months to keep it in good condition, and drain fuel if storing for long periods. Keep the unit clean, inspect for leaks or damage, and follow the manufacturer’s service schedule. Regular maintenance ensures safe, reliable operation when you need it most.

Most modern portable generators and lithium batteries provide “clean” power with stable voltage and frequency, making them safe for sensitive electronics like laptops, phones, or medical devices. Inverter generators are especially recommended, as they produce a pure sine wave output. If using a standard generator, consider a surge protector or power conditioner. Always check your device’s power requirements and match them to the output of your battery or generator to avoid damage.

Most airlines restrict the transport of large batteries (especially lithium) and generators due to safety regulations. Small lithium batteries (under 100Wh) may be allowed in carry-on luggage, but larger batteries and all fuel-powered generators must be shipped as dangerous goods or transported by ground. Always check with your airline or shipping company for current rules, and pack batteries in their original packaging with terminals protected. For international travel, consider renting or purchasing power solutions at your destination.

Store batteries in a cool, dry place away from direct sunlight and extreme temperatures. Keep them partially charged (around 50–80%) if storing for long periods, and recharge every few months to maintain health. For generators, drain fuel or add a stabilizer, change the oil, and store in a dry, ventilated area. Cover the generator to protect from dust and moisture, and check for pests or corrosion before next use. Proper storage extends the life of your equipment and ensures it’s ready when you need it.

Pure sine wave inverters produce a smooth, consistent electrical signal, making them safe for all electronics, especially sensitive devices like laptops, TVs, and medical equipment. Modified sine wave inverters are simpler and cheaper but produce a choppier signal, which can cause noise, overheating, or malfunction in some devices. For most camping and caravan setups, pure sine wave inverters are recommended for maximum compatibility and safety.

Check the wattage or amperage requirements of each appliance and compare them to the output ratings of your generator or battery. For batteries, add up the total daily energy use in amp-hours or watt-hours and ensure your battery bank can supply enough power. For generators, ensure the running and starting wattage of your appliances does not exceed the generator’s rated and peak output. If in doubt, consult product manuals or ask our team for guidance.

Yes, inverter generators are specifically designed for quiet operation, often producing less than 60 decibels at typical loads. These generators are ideal for campsites, caravan parks, and areas with noise restrictions. They’re also more fuel-efficient and provide clean power for sensitive electronics. Always check the noise rating (dB) before purchasing and position the generator away from sleeping areas for maximum comfort.

You can use your car or caravan battery to power 12V devices (like lights, fridges, or pumps) using the appropriate sockets or adapters. However, draining your starter battery can leave you unable to start your vehicle, so it’s best to use a dedicated deep-cycle auxiliary battery for camping or extended use. For 240V appliances, you’ll need an inverter connected to your battery bank. Always monitor battery voltage to avoid deep discharges that can shorten battery life.
