Choosing for the Right Generator

Electricity is such an integral part of our life that we can’t imagine not having access to everyday since many of our daily tasks require them to be done from doing your office job, field job, taking care of the house, and for entertainment or other amenities. While in most cases we will have constant access to power supply, depending on where you live and currently living sometimes we face a problem to get a reliable supply hence generators are very useful.

Chances are, many of us need a generator with varying sizes to fit different applications and it is always best to buy the one that matches with your kind of usage. When choosing for a generator, the most important part is their capacity since this is directly related to what we can power with them. There is a simple method however, to determine how much we need to have but first you must list down the appliances we will be powering with the generator.

Second is look for their start up and running power usage in watts for each one of the appliances and then add 10% if the total for safety net. Third is find the suitable generator that can produce a maximum power equal or better exceed the totals. In addition, also consider the starting power depending on the appliances since different types of motors can draw different amounts of power needed to start up. For example induction motors such as in air conditioners can draw 2 to 5 times its running power to start up.

Another method is shopping based on what common job the generator is needed or what type of application they are going to be used in. For those who are buying for their house, we can choose from the biggest standby generator to portable model. Large generators will produce enough power to fulfill the appliances in the house and replace the power supply in time of power outage. We can decide the size by the frequency of usage as well such as the midsize inverter or recreational inverter for people who rarely experience the outage.

If your house does experience power outages a lot, the bigger the better as we need them for a prolonged time but those with less struggles can opt from the very compact models such as Honda EU2200i Vs Predator GP2200i or upper mid-size models. Smaller models are usually popular among campers as well due to their convenience and portability and depending on your appliances, they may offer a good level of comfort and lasting supply when there is no reliable supply.

About Westinghouse iGen4500 and Predator 3500

Personally, we prefer to buy based on the power they supply and match them with any electronics we will be using to get the best option possible. Now when you already list down and estimate how much wattage needed during the lack of power supply, it is the time to see what the market has to offer as there are so many of them out there. Most of us however, ofteno go for named brands because they also tend to be more reliable.

But, if you want to spend some time looking at other models or options, there are quite a lot of reliable units without the hefty price and for those who want to optimize their budget, Westinghouse and Predator are two nice companies to shop from. They are not as popular as other big names such as Honda but performance and quality wise, their generators are often pretty much similar to each other but at a fraction of the cost from big brands.

Depending on what you need to power from the generator, they carry quite variants with different ratings to match your application and those looking for a mid-size yet still portable unit may want to check out both Westinghouse iGen4500 and Predator 3500. These two are larger than the common units we often bring in our RV but it doesn’t mean that you can use them in such applications since we do think they are still fitting the usage very well.

This type of medium size inverter is the most versatile in our opinion because while they are not something that we can hand-carry around, the amount of power they generate are suitable for home and mobile use. Westinghouse iGen4500 and Predator 3500 are also highly rated due to their reliability and performance but not only made by different brands, they are also rated differently and even in a glance you can decide which to go based on how much power is needed for the application.

Westinghouse iGen4500 and Predator 3500 Design

Since Westinghouse iGen4500 and Predator 3500 are quite large for transporting, they are come already featured with wheels attached but the latter have a two pairs of them at the front and back while the former only has a large wheel at the back which means you have to lift it when moving around. Both designs carry pros and cons because a single pair will prevent the unit from gliding in an angled surface but heavier to push or pull around as we need to lift it a little bit; in this model using a telescopic handle. 

On the other hand, two pairs of wheels make Predator 3500 convenient to push around but may also require a stopper like a small stone or piece of wood to prevent it from gliding when unguarded. While iGen4500 produces more power, their weight and form factors are about the same at 25.5-inch by 17.5-inch compared to 22.7-inch by 17.3-inch. As for the fuel, they are equally using gasoline and equally will store at about 3.4 gallons.

Westinghouse iGen4500 and Predator 3500 Capacity

Moving further, let’s check what Westinghouse iGen4500 and Predator 3500 can offer and how they can power you appliance but even from the model name itself we can already guessed that the iGen4500 will be more capable in delivering more power as it maximum rated is 4500 watts while the running power itself is rated at 3700 watts compared to the Predator model which produce maximum of 3500 watts and with running power of 3000 watts. With this difference, we can clearly see that you can rely on iGen4500 for heavier application.

Similar to many other generators nowadays, these two are also using inverter technology which is more modern and seen as the cleaner option compared to the more traditional technology. Usually they are made with portability in mind which is why most can be very compact. Technically they are more complicated but one of the biggest differences is they electronically throttle the engine up and down to meet the power demand instead of running them at full capacity all the time thus, in general they are more efficient as well.

Westinghouse iGen4500 and Predator 3500 Performance

Moving into the performance part, Westinghouse iGen4500 and Predator 3500 are very much reliable and as long as you don’t exceed the power rating, we will be fine. You can power AC units from 10 to 15k btu depending on how much they need to start since this appliance draws at least double the running power so if you have for example a 15 btu unit then make sure to start the AC first. The 3500 seems to only power this much or probably with some light bulbs or phone charging. 

But, the iGen4500 still has quite the amount even after powering this much load and usually this type of application will take about 50% of its capacity so you can add more into the line such as microwave or other appliances while still below the load.

Westinghouse iGen4500 and Predator 3500 Features

The last part we want to mention is their additional features and the first thing we notice from Westinghouse iGen4500 and Predator 3500 is their parallel connector which means these two are able to be paired with another suitable generators to increase the power rating yet, we need to find the adapter first as it is sold separately. Our second favorite feature is the display because it is very useful as you can see the capacity and load easily to prevent overloading it.

These generators are amazing because they work as claimed and as long as our application is below the rated power, these two will work very well without any issue. The fuel tank can last for a satisfying amount as well so you can sleep comfortably at night with full-tank. The difference is only on their power rating because iGen4500 will easily handle various electronics with its addition of 700 watts of running power and 1000 watts of maximum output so then you can use a variety of appliances.
