#2. Cat RP7500E Gasoline Generator (7500 Running Watts/9375 Starting Watts)

Are you a generator operator looking for the best portable generator on sale for construction purposes?

You might want to know the CAT RP7500E is somewhat of an exodus from Caterpillar’s contemporary bulky generators. This model unit is a design build aimed at presenting you with huge power generation in a more portable package. Admittedly, on this front – it excels to a certain degree.

At a glance, the model still is what you’d consider a bulky piece of machinery. However, thanks to the wheels strapped on to it, you’ll have an easier experience moving it around than you would most of their typical behemoth generators. Let’s have a look at why this model might be a good buy for your jobsite:

What is in the Package?

Here’s what the manufacturer includes in the packaging:

  • CAT RP7500E Portable Generator
  • Li-on Battery (for electric start)
  • Wheel Kit
  • Maintenance Tool Kit
  • User Manual

Operation & Ease of Use

Even though you can’t remotely start this generator, it has a lithium-ion battery for its electric start switch; you just have to flick it and it’ll instantly be up and running. The battery always charges up when the generator is running.

This model comes with six different completely-covered, recessed outlets that you can use concurrently. You don’t have to worry about plugging sensitive appliances to this CAT because it has a voltage regulator that keeps the voltage smooth.

There are other built-in safety features to keep it safe when you’re away. In case the oil or fuel levels get too low, or if this generator is somehow tipped over, it is designed to automatically switch off.

The control panel of the RP7500E has LED lighting for effortless night operation. You might want to keep in mind that the model wasn’t designed for you to use power tools at night. Its 4-in-1 digital screen illuminates too when it gets dark displaying the voltage (in use), frequency, run hours, and total hours.

What’s more? The ergonomic design build of this 192.5lbs model makes moving it around effortless. Its double-hinged padded handle and large, indestructible wheels help the operator when pulling or pushing.

Noise Level & Power

The CAT RP7500E is strapped with a powerful 420cc, OHV engine and a 7.9-gallon fuel tank for a power yield of about 7,500 running watts and about 9,375 surge watts. This is definitely more than enough to power a good number of energy-intensive appliances at the same time.

You can expect this model to present you with up to 11hrs of runtime at 50% Load before you have to refuel it. A full-tank of fuel should be sufficient to last you all day at the jobsite, unless you’re making use of the RP7500E for an extensive period of time.

It’s quite unfortunate that the tradeoff for this powerhouse’s wattage range is its noise generation. Be it as it is – it might not be the most deafening generator around, but it certainly isn’t the one with the quietest functionality by any stretch.

You might want to remember that it’s primarily built for construction sites. Therefore, it comes with amplified power yields and proportionate decibel levels.

Verdict: Should You Buy It?

All things considered, the CAT RP7500E isn’t the generator you’d want to go for if you’re looking for one that’s small and stealthy. On the flipside, if you’re online looking for the best portable generator, with huge power yields and an array of features, for industrial use – then you’ll be impressed with this invention by CAT.
