Should I Buy or Rent a Portable Generator?

Quick Answer: If you experience frequent power outages and have ongoing backup power needs, purchasing your own portable generator is likely the better option. Buying allows you to choose a model with ideal wattage, runtime, and features to match your requirements. One-time upfront costs are typically recouped over time compared to renting.

For sporadic or short-term uses like events or renovations, renting a portable generator is often more cost-effective. You pay only for the time period you need it, without storage and maintenance responsibilities.

Evaluate your power demands, budget, and projected frequency of use. For regular outages, buy. For periodic needs, renting is likely the better choice.


When your power goes out, portable generators provide emergency backup electricity to keep freezers cold, phones charged, and lights on. Portable generators range from small models that can run a few appliances to industrial-sized units that can power an entire home. With so many options on the market, one of the first decisions you need to make is whether to buy a portable generator or rent one when needed. There are compelling reasons to consider both options. By understanding the critical factors involved, you can determine if owning or renting a generator is the best choice for your situation.

Reasons to Purchase a Portable Generator

Owning your own portable generator means having backup power ready and waiting for outages, both expected and unexpected. Portable units are designed to be easily set up when power interruption occurs. Keeping it fully charged or fueled and maintained means you can start it up promptly. Having a generator on hand can provide peace of mind, knowing you have a reliable source of electricity when the lights go out.

Purchasing your own generator also allows you to select a model that aligns closely with your power requirements. Portable generators are available in a wide range of sizes and capabilities. Essential factors to consider are the generator's wattage, runtime, number of outlets, noise level, and unique features. Carefully calculating your needs allows you to choose the right specs and avoid paying for excess capacity you won't use.

For instance, if you want to back up essentials like a fridge, freezer, and medical devices, a mid-sized unit with over 2000 running watts may be sufficient. Or if you need to power your whole home, a larger 10000–15000-watt standby generator is likely required. Run time is another significant consideration. The longer a generator can operate, the less disruption you'll experience. Models with runtimes of 8-10 hours or more allow you to weather longer outages.

Making this upfront investment in a home generator pays off over time in cost savings in fuel or electricity compared to repeatedly renting units for each outage. If you want to have the most cost-effective portable generator, portable solar generator or portable power station is highly recommended. And learning the ins and outs of operating your own generator helps you use it more effectively whenever backup power is needed.

Situations Where Renting a Generator May Be Better

Renting a portable generator provides an affordable, flexible option if your needs for backup power are only occasional. For example, you may want a generator available for planned utility work or renovations causing temporary electricity shutoffs. Renting allows access to a generator just during the outage period without having to buy, maintain, and store the unit long-term.

Generator rental is also handy for events and large gatherings away from home where you need to power lighting, tools, sound equipment, or cooking devices. Rented generators can provide temporary juice for food trucks, outdoor job sites, concerts, and camping trips rather than using your own portable unit.

The main benefit of generator rental is convenience and cost savings. You can reserve the precise size generator your situation demands without wasted capacity or upfront investment. Units can be delivered on the required date and picked up promptly after use. Rental fees often range from $50-150 per day or $200-500 weekly, a reasonably affordable rate compared to purchasing.

Granted, lack of ownership also means less familiarity with the operation of the rented unit. But, rental centers can provide a quick tutorial on startup, hookup, refueling, and shutdown. Between events, you don't have to store or maintain a generator, which saves space and hassle. While rented generators aren't available for unexpected outages, they can be ideal for temporary or periodic power needs.

Key Factors to Consider Before Deciding Buying or Renting Portable Generators

When choosing between buying and renting a portable generator, start by realistically assessing your anticipated frequency of use. How often has loss of household electricity left you in the dark? If power failures are common in your area, owning a generator likely makes sense. Infrequent or one-off usage is better suited to rental.

Also, carefully consider the wattage capacity and features your situation requires. A rented generator must provide enough output to run essential appliances and devices you need to power. So, make a list of wattage demand and look for a rental unit that meets it-factor in non-essential items you'd like to run as well.

Home type and size should also inform your generator decision. Permanently installed standby generators may work better for larger homes that require substantial backup power. For apartments and smaller spaces, a portable generator is easier to store and operate. Be sure to check that generator use is even permitted in rental units before deciding.

Overall costs can vary widely depending on your specific needs. While renting a generator for a weekend event may be only $100, repeated short-term rentals add up. Buying a high-capacity, low-noise generator for whole-home backup could cost $3000 or more. Make sure to compare estimated rental fees to purchase prices to see which fits your budget.


The decision ultimately depends primarily on the frequency, duration, and power level your household or event requires. For recurrent outages, purchasing a generator designed for your wattage demand makes financial sense in the long term. For one-off or occasional needs, renting provides convenience and cost-effective power access. Carefully weighing these factors allows you to choose the optimal generator solution when emergency power is required.
