For this update, I wanted to add some larger models that bordered the upper end of the portability scale (around 120-130 pounds), since generators with smaller capacities can easily be substituted with portable ac power supplies. As models become larger (in capacity), it becomes harder for ac supplies to match generators in capacity without getting very expensive, which means that these portable generators have a monopoly on the market, and we can highlight some unique models.
I updated the DuroMax XP4400E with the DuroMax XP4850EH; the latter is only 10 lbs heavier, but has a noticeably higher starting and running power rating. Unfortunately, I had to remove Anker Powerhouse as it really had no place in this list as such a low-capacity model. I removed the Briggs and Stratton 30651 and replaced it with the slightly cheaper Rainier R4400 which has about 5 times as much capacity (8 hours at 25% load (1700W) for the Briggs and Stratton vs. 18 hours at 25% load (3600W) for the Rainier). I also updated the Honda EU2000 to the newer Honda EU2200i – a more efficient model with an updated engine which gave it a slightly larger capacity and better ventilation and airflow among other benefits, which makes this already-reliable model even more reliable.
I still think that the Generac 7117 is the best model in terms of overall economy and while the Honda EU2200i probably slightly edges out the Generac 7117 in overall performance and reliability, its about twice as expensive. On the other hand, the Champion RV Ready has the largest capacity.
The Many Uses Of A Portable Generator
Indeed, the primary reason many people choose to buy a generator is to mitigate the effects of a power outage.
With a decent generator, you can keep your fridge running, a lamp lit, and even an air conditioning unit or heater running all at the same time.
Anyone who thinks they will never have a need for a portable generator likely has a few misconceptions about generators, as well as about the unpredictable nature of life. The fact is that a portable generator may someday make the difference in your family's safety and security, or at least in a night spent in comfort.
Indeed, the primary reason many people choose to buy a generator is to mitigate the effects of a power outage. With a decent generator, you can keep your fridge running, a lamp lit, and even an air conditioning unit or heater running all at the same time. You can also use the generator to keep phones and computers charged, or even to keep sensitive medical equipment operational during a power outage. Opting for a portable generator means you can always get power where you need it during that blackout. Just make sure you also have a few gallons of gas on hand.
A portable generator is a regular fixture at worksites around the world, and using a generator instead of the power supply at an unfinished home or building (or one undergoing heavy renovations) can help workers avoid the dangers of exposed and/or potentially compromised wiring. Many portable generators put out as many as 3,000 watts of power at their higher settings, and that's enough power to run full-sized power tools such as a table saw or planer.
While you must be sure to first check the local laws and ordinances surrounding their use in the field, bringing a portable generator along when you go camping can lead to a truly luxurious outdoor experience, complete with the comforts of light, small appliances, and media devices even as you enjoy nature and fresh air. Just make sure to factor in the noise levels of the unit you're considering, as some portable generators are so loud they can damage the allure of a trip out into the woods or mountains.
Choosing The Right Portable Generator
Portable generators are not cheap. Even the lower priced models cost several hundred dollars, and many higher end units cost upwards of $1,000 or more. Monetary expectations aside, the two main factors to consider when choosing the right unit are size and power output.
These generators are ideal for use as backup power during an outage, when it's uncertain for how long you'll need to run an appliance or climate control device.
Size is arguably the more important of the two factors when it comes to choosing a portable generator: if you buy a unit that's too large for you to easily move to wherever it needs to be (from the basement to the patio during a power outage or from the truck to the tent when you're camping, to name two examples), then your generator is not exactly portable, as far as you are concerned. Make sure to choose a unit you can actually move with relative ease. Many weigh little more than fifty pounds, so this should not be too hard to accomplish.
Once you know how large a generator you can comfortably move around, then look to the watts it produces. Many units can run for hours on end at their lower settings, which tend to put out around 1,000 watts of continuous power. These generators are ideal for use as backup power during an outage, when it's uncertain for how long you'll need to run an appliance or climate control device.
If you work with larger power tools, or if you anticipate the need to keep multiple devices running at the same time, then you will need to select a more powerful unit and accept the size and price tag that comes with it.
Also, do think about the volume associated with the generator you're considering. Some units create only about fifty decibels, allowing you to chat even while standing beside them. Others are so loud you will not be able to hear yourself think even when a dozen feet away.
Portable Generator Use And Safety
Always keep children and pets away from a working generator. That holds true even when the unit is not in operation, as it is likely to be filled with combustible gasoline. Used properly, a portable generator is a safe and reliable tool. Remember, generators involve both gasoline engines and large amounts of electricity, both of which can be extremely hazardous around youngsters or animals.
At worst, an overtaxed generator may burn itself out, leaving you with one very expensive, oversized paperweight.
Make sure to keep the kids supervised and the pets sequestered whenever a generator is in use, and make sure to store your portable generator in a safe, secure spot when it is idle. (Thankfully most portable units are small enough to tuck away in almost any garage, shed, basement, or even a closet, but be mindful of potential fumes prior to indoor storage.)
Make sure to carefully review your generator's manual prior to use, noting the necessity for any special types of fuel and for how much and how often it requires oil, if need be. It's also important to pay close attention to your portable generator's maximum load capacity and never try to pull more power than that for which it is rated. Overtaxing your generator will likely cause it to shut down, cutting the electricity to everything to which it is supplying power. At worst, an overtaxed generator may burn itself out, leaving you with one very expensive, oversized paperweight.
