These converters are recommended when you need to power something that is rated for 1000 watts and higher. Appliances like heating equipment, power tools, motors, televisions, and even laser printers require 2 or even 4 times as many watts to start than what the printed rated wattage.

Because this unit is capable of providing you with 3000 watts of power, you can use this device for anything that requires AC power.

This power converter features a safety breaker that will turn the unit off once the voltage has reached an unstable level, which is usually the result of the unit being connected to an non-grounded outlet that will cause a larger fluctuation of power.

This converter features a full range of over-current protection through the miniature circuit breaker. The miniature circuit breaker is much more sensitive to over-currents than a regular fuse. This makes the unit more reliable and safer to use.

Rockstone 3000W Power Converter Back

People remarked that the device was constructed much better than they had expected. They appreciate that when the unit is turned on, it runs silently. Some were surprised that despite how compact it is, it is quite heavy.

Some have also commented that they like that they can plug in power tools like drills or sanders and the tools work very well. One customer did mention that you will want to check the settings and adjust the in and out voltages on the back before using it.

Another customer commented that the unit does get warm when it is in use, but it doesn’t get hot. They went on to say that they keep the unit plugged in at all times and it is capable of functioning well with a constant load.

Although most of the reviews for this product were positive, there were some people who felt that this device was not the right choice for them. These customers were disappointed because the device they received didn’t have the proper connections they needed. They did send the unit back and they said dealing with the customer service was pleasant.

Other customers reported that their devices stopped working only after a year. This person had the same thing to say about customer service, and they were able to get a second device.

However, the second unit was defective, as it would work sometimes and other times it wouldn’t. Another customer said they used this device for light applications and the on/off switched stopped working only after 4 months. A few others commented that when the unit is running, it emits a foul odor, even after several uses.

Final Thoughts

When you’re looking for the top rated power inverter, you’re going to want a device that is going to handle all of your needs. The Rockstone 3000W Power Converter is designed to be that device. This device provides you with simultaneous 3-mode output options: 5V USB Port / 120V USA Output Socket / 220V Universal Output Socket.

We like this device because it features a miniature circuit breaker that is much more sensitive than a fuse on other inverters. The miniature circuit breaker ensures that should there be any fluctuations in the current, the device will shut off. This feature makes the unit more reliable and safer to use.

The Rockstone company supports the US military and they will ship their product to overseas military APO/FPO/DPO addresses. Since they do ship overseas, this is a wonderful device for those who miss the comforts of home while they are stationed elsewhere.

Perhaps the thing that we like the most about this device is that it comes with a 3-year manufacturer’s warranty. So if you should have any problems, you can contact Rockstone’s friendly customer service and find a solution to your problem, be it a return, repair, or a replacement.

In our opinion, a 3-year warranty is reason enough to give this product a shot. Not only is it a powerful device, but the warranty protects you if something should happen to the device while using it. It’s a win-win!
