When it comes to choosing a generator especially one that is needed for everyday use, over and above anything else you would need one that is highly reliable as well as being up to the job which you require it for. Cheap half-hearted efforts that you see being sold as a bargain in a large store probably would not be an ideal purchase.

Performance is vital as there is nothing worse than coming to depend on a particular appliance only to be let down in your real hour of need.

A diesel-powered version is probably not a good idea either as they tend to be exceptionally large which makes them a lot less portable than most other generators plus they are not really suited to the use of being an everyday generator unless you were thinking of powering a small office off of the beaten track on a daily basis.

So gas power is the way to go and looking at the higher end of the market to cure any reliability issues which means a fairly high wattage and horse power generator. The good thing about a larger model portable generator is that it will be capable of powering several small items all at the same time or much larger items individually.

Another big advantage with a modern-day generator is that even though they may have a high output and come with many gizmos and gadgets integrated for uninterrupted electricity flow and such like they certainly maintain a portable size.

Without knowing the specific requirements that you might require a generator for it is difficult to gauge a specific model, but if you go on the basis that a generator putting out about 8,000 watts will be able to power most of your electrically driven household items or singularly on the much larger items such as heating water etc. then you have an idea of what you can expect performance wise.

This gives you an engine size of about 400 to 500cc providing you with around 14-horsepower equivalent to about (8,000 watts). When you get to these levels it is important to know the run-time on a tank of gas and noise levels, although you will find most portable generators these days with these capabilities will probably incorporate some kind of noise distribution system or special muffler.

It makes sense to use a 400cc plus generator because this way you will have both the reliability and longevity that is required if you intend using it frequently or even every day. Anything less will just not be up to the job and will certainly not have anywhere near the power capabilities.

The really good thing is that once you have bought a generator with this type of ability you will probably never want to be parted from it, after all in an emergency situation or complete power outage it would be the backbone for stability.

Gone are the days when owning a generator is considered a luxury, these days you can pick up some pretty impressive small powerhouses at very reasonable prices.

There are a few generator manufacturers that fit the bill so it is worth having a look around. The bottom line is that it is worth buying one that is bigger than you might need as this way you will have it for a much longer period and it will always provide you with more than enough power.

Finally, in order to get the best value for money you are better off buying online, not just your generator, but pretty much anything these days.

By buying online you can get some really great deals as there is nothing like the overheads involved or found when you buy from a store or mall and especially when buying the bigger price items. By buying in this way it should not be too difficult to make a saving somewhere between $30 to $40 dollars when choosing a generator similar to one that we have been discussing.

Having your very own residential generator is very important if you want to secure your home from a power outage. During a blackout, a residential generator allows you to continue usage of important electric appliances and devices like your air-conditioner, heater, lights, refrigerator, and computer. It works by converting mechanical energy into electrical energy.

A residential generator can either be portable temp mail ninja or stationary (stand by), depending on what suits you best. These generators can run on natural gas, diesel, gasoline and LPG (liquefied petroleum gas). Portable generators that run on gasoline are the cheapest models. However, they have a short running time and you would have to refill their gas tanks time and time again. This is also not reliable as a long-term power backup since gas pumps might not work during blackouts.

On the other hand, a generator that is stationary can supply continuous power since they are directly attached or hooked up to an external fuel source, such as an external gas line. A portable generator can also be attached to an external source, thereby extending running hours.

Aside from this, portable generators have to be transported from the storage, connected into loads, filled with fuel or hooked to a fuel line, and manually operated for it to function. Meanwhile, a permanent standby residential generator can start with just a push of the button or automatically (without manual operation), if it comes with an automatic transfer switch. This is because it is already attached to the house wiring or fuel source. Usually, the transfer time of an automatic system is around 10-30 seconds. A standby generator is also very efficient in terms of the higher power levels it produces, when compared to portables. Although these generators are indeed costly, it would be worth every cent in protecting your home from a long-term power outage, as it can be used to supply electricity to the whole house.

In choosing your own residential generator, make sure you not only consider wattage and price, but also take into consideration how long you might need emergency power, fuel availability, convenience of use, and safety. You should also consider whether you want to power the whole house or just a few mission-critical select circuits. If you have the financial resources to power the whole house, go for it. If not, you can just choose select circuits that are most important to you, like those leading to lights, refrigerator, heater, air-conditioner, and such.

Just be forewarned that having a residential generator might be potentially hazardous. It can cause unwanted fires, electrocution, and a high emission of a poisonous gas, carbon monoxide.

Overall, you should choose a residential generator that suits your needs. Assess whether you need it for short-term/long-term blackouts and for whole house/select circuits. Of course, you should determine the wattage requirements of the electrical devices you need to power at the same time, so you can look for a generator that supplies the right amount of power.

Remember that there is more to buying a residential generator than its cost. It protects and adds value to your home, so consider it as a very important investment you have to make.
