Portable Generator FAQs

What is the difference between rated watts and maximum (surge) watts?

Rated watts describe the amount of power the portable generator can produce continuously. Maximum wattage is the power that the generator can produce for short periods of time. Motor starting is a good example of maximum wattage requirements.

Can the generator be used during inclement weather?

Generators can be used during a wide variety of weather temperatures, but should be protected from the elements when not in use to prevent shorting and rusting. NEVER run a generator indoors.

Can I vent the exhaust out of an enclosed area?

No. Never run the generator in the home or an enclosed area. Portable generators are designed to run outside where there is plenty of ventilation.

Does the portable generator need to be grounded?

Yes. For safety, the generator must be properly grounded. If it’s not grounded, you run the risk of electrocution. We strongly recommend that you check and adhere to all applicable federal, state and local regulations relating to grounding.

How often should I perform routine maintenance?

The maintenance schedule for your portable generator is in the owner’s manual and some models are equipped with built-in maintenance reminders on the control panel

Pressure Washer FAQs

What is a power washer?

A power washer is an outdoor power tool that makes cleaning easier by using a high-pressure spray of water to clean a surface. A gasoline engine or electric motor drives a pump, which is supplied by your home’s water supply. The water enters the pump at about 50 PSI, is compressed (and thus pressurized) inside the pump, and exits the pump at as much as several thousand PSI, depending upon the unit. This high-pressure water travels through a hose to a spray gun. The nozzle at the end of the spray gun directs the high-pressure spray as you clean.

The force of the high-pressure spray loosens dirt and flushes it away. On more professional-grade models, the spray is even powerful enough to strip paint, which is useful in paint preparation. You can use many detergents with a power washer, too, for even more effective cleaning. And there are accessories you can buy that make cleaning even easier.

What is “PSI” and “GPM,” and why are they important?

PSI is short for “pounds per square inch.” It is a measure of the water pressure coming out of the power washer. A typical garden hose dispenses water at about 50 PSI, and a coin-operated car wash provides about 700 PSI. A power washer, by contrast, typically dispenses water at several thousand PSI, depending upon the model.

GPM stands for “gallons per minute,” and describes how much water is flowing through the power washer.

You’ll find both of these ratings on a power washer, because they’re both important. Together, they provide your power washer’s cleaning power. PSI provides the “oomph” you need to lift dirt and grime, and GPM provides the necessary quantity of water to wash it away.

The real measure of a power washer’s cleaning power can be found by multiplying PSI by GPM. The higher the number, the greater the cleaning power. For example, a garden hose delivering water at 50 PSI and 5 GPM has a cleaning power of only 250. A power washer, however, delivering water at 2500 PSI and 2.3 GPM has a cleaning power of 5750.

How do I select the right power washer?

The first question you should ask yourself is where you intend to use the power washer—at home or at work. A power washer used primarily at home probably doesn’t need to be as powerful as one that is used on a job site. Around the house, for example, you shouldn’t need more than 3000 PSI. To be fully productive on the job site, though, you probably need at least 3000 PSI.

Next, ask what you want to clean. If you’re looking to simply take the dirt and grime off the driveway or patio furniture, you can use a unit with a relatively low pressure—perhaps 2500 PSI. If, however, you plan on scrubbing mold and mildew off concrete, or prepping a house for painting, you should consider a unit with a higher pressure.

Finally, think about how much cleaning you will be doing. If you’re cleaning a number of items, or if you need to clean a large area, you might want to consider a unit with a higher GPM. More water means more cleaning power, and a higher GPM will make the job go faster.

Portable Power Station

What is the difference between Modified-sine wave inverter and Pure-sine wave inverter?

Modified-sign wave inverters are the most common inverters on the market. They work great with small electronic equipment, usually anything that includes an AC power cable with the box, like what your laptop comes with. Pure-sign wave inverter produces an output that is exactly the same as supplied by an AC wall plug in your house. Although integrating a pure-sine wave inverter takes more components, it produces power output that makes it compatible with almost all AC electric devices you use in your house.

Can I use my phone while the portable power station is charging?
Yes, but at present only Rockpals 100Watt portable power station can charge and use your phone at the same time.

Once fully charged, how often do the power station have to be charged if unused?

If unused, we highly recommend charging the battery every 3 months for a healthy lifespan and storing the power pack plugged into the wall or solar panel.

Is it noisy when it runs? 

It is a big portable, rechargeable battery. It does not make any noise.
