Benefits of a Portable Home Generator

If you don’t have a home generator yet, you need to get one pronto. A home generator is one of those things that you’d rather have and not need, rather than need and not have. But eventually you’ll find yourself in a position of needing one, when you have power outage at home.

With a generator during a home power outage, you’re able to enjoy the following advantages:

  • The generator can run the air conditioner in the summer and the heating system in winter.
  • It can keep the lights on in your home so everyone can move around safely and freely.
  • You’re able to use cooking appliances to prepare food.
  • If you’re rushing to do some work on your laptop or PC, the generator can make sure that you’re able to finish the job despite the power outage.
  • Your refrigerator can keep on working, so the food inside don’t spoil (and the ice cream doesn’t melt).
  • It can get boring during a power outage, but with enough watts from your generator you can turn on the TV and the attached sound system, or even play console games.
  • If you wear a CPAP machine to bed when you sleep, the generator can run it so you can continue your sleep apnea therapy.
  • If the power outage occurs in the morning, your generator can still ensure you enjoy the coffee from your espresso machine.
  • A portable generator is generally more affordable, can move easily anywhere you want and setup wherever you need.

Basically, you won’t have to endure the lack of available electrical power even when there’s an outage at home or you’re outdoors where there’s no convenient wall socket to power your electronic devices. This capability is crucial in boosting your comfort levels, and in emergencies it can even save lives.

Which Generator is Best for Home Backup?

That depends on what you want and what you need. Do you need to only power your smartphone and laptop for work and entertainment, and perhaps a few lights and a fan to cool yourself off? For these small devices you only need a few hundred watts to get by.

But many wish to power their refrigerators so the foodstuff remains fresh. Maybe in the summer they want the AC running too. These appliances are more power-hungry, and you’ll need thousands of watts more to accommodate them. That’s certainly true if you power your whole house as if there’s no power outage at all.

Just keep in mind that the more watts you demand, the bigger and heavier the generator will be. This means it won’t be as easy to bring this particular generator to the beach or to a campsite. In addition, you’ll have to spend a lot more money for more watts.

Buying Guide: How to Choose the Best Portable Generator for Home Backup

It’s an easy decision to choose to a portable generator for home backup use. What’s not so easy is to pick one that’s best for your needs. But you can make it easier for yourself by focusing your attention on the following generator factors:

Wattage

This is of course the most crucial factor of them all. The number of watts you have will determine how many and what kind of appliances you can run with your generator. So you need to tally how many watts (starting and running watts) you need from the appliances you want to run.

For home backup, you may want to get generators that offer watts in the thousands if you wish to make sure your fridge and your AC remain running even during a power outage. A good generator can also accommodate your lights and maybe the TV too.

Price

Obviously you need to be mindful of the price. You have to balance your budget with the wattage you need, as the more watts you get will increase the price of the generator. You can’t just settle for a cheap machine that won’t give you the watts you need.

Fuel Source

Some generators run on gasoline and others on propane gas. You have to check out the pros and cons of gasoline and LPG generators to see which type suits your needs. But if both are okay with you, a dual fuel generator may be more to your liking.

You may also go for a home generator that’s basically a rechargeable battery, if your need for wattage isn’t that high. If all you really need is to make sure you have power for your smartphone and laptop, you only need a few hundred watts that a generator like this can provide. You then get to enjoy a battery generator’s compact design, low weight, silent operations, and lack of toxic fumes.

Ease of Use

It’s said that a good generator is one that even a kid can figure out how to use. So if something’s overly complicated, you may want to find a better alternative. Your generator should come with a manual, though, even if you can find lots if YouTube videos on how to use it. It’s even better if you have good technical customer support.

Portability

How lightweight and compact is it? A heavy generator won’t have to be so bad, though, if you have a nice handle and wheels to make the generator more mobile. This factor determines how easy it is to bring your generator to the beach or to a campsite.

Durability

On a per year basis, a $900 generator that runs for 10 years is cheaper than a $400 generator that only lasts for a year. That’s basic mathematics. So you need a long-lasting generator—if it’s not reliable, then what’s the point?

So check the warranty, as that gives you a clue as to how long the manufacturer expects the generator to last. You should also take note of the generator’s safety features, like automatic low oil shutdown and circuit breaker. Read the various customer reviews as well, as their complaints may reveal the shoddy make of a particular generator model.

Conclusion

Buying the finest portable generator is one of the basic ways of preparing for a power outage. It can be the difference between continuing on in comfort during a power outage and having a miserable time without any power at all. With the benefits you enjoy, every cent you spend will be worth it—if you make sure you get a good generator.
