Portable Generator Cost

How much does a portable generator cost?

Using a portable generator when there is a power outage, or where mains power is not available, is a convenient way of having electricity on hand. The cost of portable generators – whether you are buying one or renting for a short time – can vary depending on the supplier and the type of generator involved, and it is a good idea to shop around for the best deal.

General Cost

• To buy a small, portable generator – one suitable for powering a single appliance for short periods of time – will cost, typically, between $300 and $700. This will be adequate for providing outdoor light or power for an evening.
• A more powerful heavier duty model, which will run for longer on one fill of gas, will cost between $700 and $2000, depending on the level of power you need and the quality of the machine involved.
• A generator capable of powering a home – lights and appliances – for lengths of time will be a more powerful model still, and could cost anywhere between $1500 and $5000.
• Rental costs for a portable home generator can be as little as $50 a day, or as much as $200 in some cases.
• For an industrial size generator expect to pay between $700 and $1200 a week for rental.

Extra Cost

• Portable generators are powered by gas or diesel and this will not come in the price! Even when renting expect to add the cost of fuel.
• You will need heavy duty cabling for transferring the power from source to destination – this can be hired or bought, and typically costs around $30 for a good sized cable.
• If you want your generator wired in permanently an electrician will charge around $300.


• The power for generators is measured in kilowatts – Kw – and the more the better.
• Try and find a generator with wheels as they can be difficult to move otherwise.
• As the prices show, for longer jobs buying can be more cost effective than renting.
• Make sure you have a suitable location for your generator as it can be noisy.


• Prices vary greatly so decide what level of power you want and get a handful of quotes from different companies.
• Use the internet to search for the best deals.
• Consider second hand – many people buy for the duration of a job and then sell on the perfectly good second hand generator at a discount price.
