Power Tech ON Inverter Review (Power TechON Pure Sine Wave)

Updated on - 2017.12.07

Electricity has become a big part of our daily lives. From your kitchen appliances to your home electronics and every other power device in your possession, an inverter allows you to power these electrical conveniences anywhere you go. The Power TechON PS1003 Pure Sine Wave Inverter is an excellent choice for powering your home electronics, sensitive equipment, and power tools. Its portable nature makes it easy for you to install this unit for use in your cars, RVs, work sites, camping sites, and vessels. This inverter is capable of providing bundles of power in mobile and permanent installations, a reliable backup for power failure emergencies.


To best suit your power needs, the pure sine wave inverter is a more efficient choice than the modified sine wave inverter. This is because they produce clean power like utility supplied electricity which helps to run your power demanding appliances quieter, faster and cooler than the modified sine wave inverter. All these devices including your printer, microwave and any other power demanding appliance, will work properly with this inverter and do not stand the risk of getting damaged or failing unexpectedly as seen in the modified sine wave inverter. However, the pure sine wave inverter is more expensive than the modified sine wave power inverter.

Power Rating

With 2,000 watts of continuous power, this inverter is guaranteed to run any of your appliances and equipment within its wattage range as long as the load is not greater than 2000 Watts. It also has a surge capability of 4000W which helps to kick-start those appliances such as your microwave that require a large amount of power on startup. You need to check the maximum rating of your device before purchasing this inverter. Do not purchase this inverter if the power rating of your device exceeds the power rating of this inverter.

Four 120VAC Outlets 

It has a total of 4 AC outlets which allows you to connect more of your equipment directly to the inverter. This has most AC outlets than most of the similar rated pure sine wave inverters. However, these outlets are not GCFI protected. This means that they do not provide a safe and convenient way of powering your devices neither do they protect you from electric shock and accidental fire outbreaks especially when you use the inverter in wet locations.

Display Unit 

It provides you with useful information that helps you monitor the status of the inverter while in operation. Unlike the Xantrex’s display unit, the display unit is not an interactive one. It only shows you the output wattage and input power. This feature is a huge benefit of purchasing this inverter as most of the similarly rated inverters like the Go Power 2000W inverter do not have this visual feature.

LED Indicators

There are LED notification lights that indicate the status of the inverter at any point in time during operation.

Built-in USB port

This convenient 5V USB port allows you to conveniently power your cell phones and other modern USB-enabled devices. Most inverters feature this USB but while some are dual, this inverter has just one 5VDC, 500mA USB port.

Soft Start, Low Interference Technology 

The soft start feature helps to reduce the starting current of the load and makes the startup of your appliances smoother. This is one of the benefits of this inverter and a feature that makes the inverter stand out. The hard-starting appliances connected to the inverter will start up smoother with low harmonic distortion.

Heavy duty terminals 

This feature allows you to connect your batteries easily and it accommodates large electrical loads. It has large positive and negative terminal lugs to supply the high current needed for this power inverter. A separate ground lug is also provided for the safe delivery of power.

Thermostatically Controlled Cooling Fan 

The two small internal fans keep the unit cool while operating under heavy loads so proper ventilation is required for reliable operation. Like the similarly rated inverters, they are thermostatically controlled which means that they only come on when the temperature rises above the normal temperature range for this inverter. The fans are ultra-quiet and will not be any disturbance to you, unlike the modified sine wave inverters.

Remote Port 

This port allows connection directly to the remote panel accessory which gives you access to control the inverter from about 25ft. You can turn it off and on without even having to move an inch. However, this port is not wireless so you will need to connect the optional remote panel using a communications cable.


Low Voltage Shutdown 

This automatically shuts the inverter down if the battery voltage drops below 10±0.5VDC, thus protecting the battery from being completely discharged.

Low Voltage Alarm 

This feature alerts you whenever the battery voltage level has become discharged to 10.5±0.5VDC. It allows you to disconnect your devices before the inverter shuts down completely.

Over Voltage Shutdown 

This feature shuts the inverter down automatically if the input voltage rises to more than 16±0.5VDC, to prevent devices from getting damaged.

AC Overload Protection

 This feature prevents overheating and possible damage by shutting the unit down automatically if a short circuit occurs or if the loads attached to the inverter exceed the operating limits.

Thermal Protection 

This feature turns the inverter off if its temperature rises above or falls below an acceptable level.

Short Circuit Protection 

It helps to prevent against malfunction or system failure when there is low resistance.


This unit is relatively cheap for a pure sine wave inverter as it costs $249.95. It has a 1-year warranty plan starting from the date of purchase.

Pros of Power TechON PS1003 Pure Sine Wave Inverter
  • A display unit which lets you monitor system performance at a glance. The display unit and the LED notification light combination is a very powerful one because even in the dark, you can still use the LEDs to know the status of the inverter.
  • Soft start, low interference technology which is a feature other similar rated pure sine wave inverters do not have.
  • It has a maximum number of AC output sockets and a USB Port.
  • The remote switch lets you control the inverter from a convenient location, up to 25ft while the inverter itself is mounted out of sight and close to the batteries.
Cons of Power TechON PS1003 Pure Sine Wave Inverter
  • An absence of hard-wire port which means that you cannot connect directly from the inverter to your home circuit box.
  • It does not have settings that allow you to change your frequency between 50-60Hz depending on which frequency is in operation in your location. It can only be used within America as its operating frequency is 60Hz.
  • A lesser number of USB ports than the other inverters on this list.


This product on Amazon has received a fair amount of reviews from both satisfied and dissatisfied customers. Some of the customers commended the efficiency of the power supplied by this inverter and how well the inverter runs their appliances including microwaves and other hard-starting devices. However, one of the reviewers complained about the length of the wires that come with this inverter and suggested that anyone planning to purchase this inverter will do well to purchase a cable by themselves.
