What should you know before buying portable generators?

First, determine the required wattage. List essential appliances and sum their running watts, then add starting or surge watts for devices like refrigerators, sump pumps, or air conditioners. This helps you choose a generator with enough power for your needs without oversizing.

Next, understand fuel options. Petrol (gasoline) generators are common and affordable, while diesel generators offer durability for heavier loads. Multi-fuel units give flexibility if you have access to different fuels. For greener power and quiet operation, consider inverter generators or solar generators (portable power stations) for light to moderate loads.

Run time and fuel tank capacity matter. If you’re camping or facing longer outages, a larger tank and efficient engine mean fewer refuels. Look for low-oil shutoff, automatic voltage regulation (AVR), and overload protection for safe, stable power delivery.

Portability features, wheel kits, folding handles, weight, and compact design, are important for transporting around a yard, campsite, or worksite. Noise level matters too; quieter models are ideal for camping or residential areas where you don’t want to disturb neighbours.

Consider the accessories and add-ons: weatherproof covers, parallel capability to connect two units for extra power, extension cords, and maintenance kits. Always buy from reputable brands and check warranties and after-sales support available on Wowcher.

What are the most popular types of Portable Generators?

Inverter generators are among the most popular for home backup and camping thanks to quiet operation, lightweight design, and stable power suitable for sensitive electronics like TVs, laptops, and phones. They typically run on petrol and some models support dual-fuel options or solar compatibility.

Open-frame petrol and diesel generators deliver higher continuous power, making them ideal for construction sites and longer outages. These units are robust, versatile, and often more affordable per watt, though they tend to be louder and heavier than inverter models.

Solar generators or portable power stations provide clean energy with virtually silent operation and zero emissions, perfect for camping, caravans, or reducing fuel dependence. They’re great for charging devices and running LED lights, but high-wattage appliances may require larger systems or hybrid configurations.

Multi-fuel generators give flexibility to use petrol, diesel, or propane, which can be a smart choice if you want options during shortages. Propane generators are convenient for long-term storage since propane stays stable, while diesel units offer longevity under heavy use.

For outdoor enthusiasts, camping generators that balance weight and noise with practical runtime are especially popular. In residential areas, quiet or inverter models are preferred to keep neighbours happy and to protect delicate electronics.

How to maintain Portable Generators?

Regular maintenance keeps Portable Generators reliable. Change the oil after the first 20-30 hours of use, then follow the manufacturer’s schedule. Replace air filters as needed and inspect spark plugs for signs of wear to maintain efficient combustion.

Use fresh fuel and stabilisers if storing for extended periods. Drain and run fuel out of the carburettor before long storage to avoid gum build-up. Check battery health on electric start units and keep the battery charged during periods of inactivity.

Keep the unit clean and dry, store it in a sheltered area, and cover it with a breathable generator cover when not in use. For units used in damp or dusty environments, check air filters and exhausts regularly to ensure optimum performance.

With Wowcher, you can find generator maintenance kits and protective accessories to extend the life of your Portable Generators while enjoying ongoing deals and trusted brands.

What are portable generators typically used for?

Portable Generators provide backup power during power outages, keeping freezers, fridges, lights, and essential appliances running. They are also invaluable on building sites, for contractors needing reliable power for tools, drills, and compound lighting.

For campers and travellers, portable power stations and compact inverter generators offer quiet, portable electricity for cooking, charging devices, and lighting without relying on mains power. Event organizers may use generators to power sound systems, lighting rigs, and outdoor activities in remote venues.

With Wowcher, you can discover discounted Portable Generators designed for home, outdoor, and professional use, with accessories like parallel kits and extension cords to tailor power solutions to your needs.

Can I use a portable generator indoors or in enclosed spaces?

No. Portable Generators emit carbon monoxide and should never be used indoors or in enclosed spaces, garages, or sheds. Always place the generator outdoors in a well-ventilated area, at least several metres away from doors and windows. Use a CO detector in the home and follow the manufacturer’s safety guidelines for safe operation.

If you’re using a generator near living spaces, ensure the area is dry, away from vegetation, and protected from rain. Use heavy-duty extension cords and avoid daisy-chaining multiple devices to prevent overloads. When possible, connect essential appliances through a dedicated circuit and consider a transfer switch installed by a qualified electrician for safe home backup power.

How do I calculate the right wattage for essential appliances?

Start by listing each device and its starting wattage (surge) and running wattage. For example, a fridge may require 600W running and 1200W surge at start, lights may need 60W, and a laptop charger may draw 65W. Add each running wattage for a total running load, then add the highest surge wattage to determine the minimum generator size you need.

Choose a model with a little headroom, ideally 20-30% higher than your calculated load, to accommodate startup spikes and avoid running at full capacity constantly. If you anticipate occasional spikes, consider a parallel-capable inverter generator paired with a second unit for extra power when needed.

On Wowcher you’ll find easy-to-read specifications including running watts, surge watts, and runtime so you can select the right size for your essential appliances, comfort electronics, and power tools.

What safety tips should I follow when buying a portable generator on Wowcher?

Always check the warranty length and what it covers, as well as the brand’s reputation for reliability. Look for units with essential safety features like automatic low-oil shutoff, overload protection, and CO detectors where applicable. Verify that spare parts, service centres, and accessories are available in the UK for quick support.

Read the product reviews and ask about run-time, noise levels (dB), fuel efficiency, and portability. Consider bundled deals that include essential accessories such as wheel kits, weatherproof covers, and transfer switches. By shopping on Wowcher, you gain access to verified sellers and exclusive discounts while assessing real user feedback for confidence in your purchase.
