Whistler 2000 Watt Inverter Review XP2000i

For many road users, a vehicle is much more than a means of transportation. It could be your home, office or something else that expresses your need. Whether you are camper, traveler or a mobile home/office owner, a power inverter comes in very handy in handling your electrical conveniences. The Whistler 2000W Power Inverter XP2000i is a perfect addition to use in your mobile home, camp site, construction site, remote job sites, road trips and other off the grid locations where power is needed. It is a portable inverter designed to handle high surges and protect charging devices. It will meet your charging schedule of multiple electronics and power a variety of devices from your car, truck or RV. Whistler 2000W Power Inverter XP2000i is a perfect choice for drivers, campers and for home use during a power outage.


Although pure sine wave inverters are a more preferred choice due to their ability to produce clean power and run your electrical conveniences smoothly, the modified sine wave inverter can also be an excellent cost effective choice for you especially if you do not have too much load to run. This inverter type is perfect for running equipment that runs on non-sinusoidal currents such as your electric heaters and bulbs. The major advantage of purchasing this inverter type is that it is less expensive than the pure sine wave inverters and they run simple systems efficiently. If your equipment your inverter will run well on a modified sine wave current, you may as well save money and purchase this inverter type.

What is in the box?

The Box contains the Whistler XP2000i Power Inverter and the User manual. The features of this inverter are listed below.

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 continuous and surge 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.

Three 3-prong 110V Standard North American AC Outlets 

They supply 110VAC to your appliances. If your appliances do not match the shape of this sockets, you will need a travel plug adapter in order to plug in. However, they are not GCFI protected like the pure sine wave inverters. 

Dual USB port output for powering your home appliances and charging USB compatible devices respectively.

The USB Port is for powering your home appliances and charging USB compatible devices respectively.

Digital Power Meter for monitoring power usage i.e. the input volts and output wattage.

This feature is for monitoring power usage i.e. the input volts and output wattage.

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.

Remote Control Outlet

The inverter is designed to be operated from a remote location via a WHISTLER Remote Control Switch which plugs into this port. It 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 remote control using a communications cable.



Whistler Remote Control Switch: You can control and monitor the inverter with ease from inside your motorhome via this switch. However, the connection process is not wireless. You connect this panel to the inverter via the remote cable that comes prepackaged with this inverter.

ANL Fuse Kit: This kit helps to protect the batteries from accidental direct current (DC) cable shorts that can cause the batteries to explode. You are required to install ANL fuse close to the positive battery bank terminal for safe operation.


Low Voltage Shutdown: The LED illuminates RED and automatically shuts down the inverter when the battery voltage drops below 10±0.5VDC, thus protecting the battery from being completely discharged.

Low Voltage Alarm: This feature is an indication that your battery is in need of a recharge. The alarm goes off 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: The LED illuminates RED and automatically shuts down the inverter if the input voltage rises to more than 15.5±0.5VDC, to prevent devices from getting damaged.

AC Overload Protection: The LED illuminates RED and the inverter will automatically shut itself down when the continuous draw of the equipment being operated or the surge draw of the equipment, exceeds the rated capacity. It prevents possible damage to the inverter and equipment connected to it in the event of a power overload.

Thermal Protection: This feature turns the inverter off if its temperature rises above or falls below an acceptable level. The LED will illuminate RED and the inverter will automatically shut down when the temperature exceeds the limit.

Short Circuit Protection: The inverter will automatically shut down until the short is removed. It helps to prevent against malfunction or system failure when there is low resistance.

Smart Surge Control is another safety feature of this inverter where it will attempt to start loads above the continuous rating for up to 10 seconds. This inverter has a high surge capacity i.e. it handles short term overload perfectly, to help start up your hard-starting appliances like microwave, AC, large power tools etc. and protect charging devices.


The cost of this inverter, $157.80, is a good price for a modified sine wave inverter. The warranty plan for this unit is limited to 2 years. The limited warranty is void if the unit is abused, modified, installed improperly or tampered with.


  • Its dual USB ports are compatible with charging your tabs, iPads, and cell phones.
  • It has a higher number of AC outlets than most of the similarly rated inverters
  • It is very cost effective and the cheapest one on this list. You can purchase one of this product at $126.98.
  • It has a high surge capacity (handles short term overload perfectly) to help start up your hard-starting appliances like microwave, AC, large power tools etc.
  • It does not produce clean power like the pure sine wave inverters do.
  • Although it is a heavy-duty equipment, it is not best suited for your sensitive and power demanding appliances over a long period of time. This is because the power produced by this inverter caused these appliances to wear and tear with time and can cause them to fail unexpectedly.
  • It does not have a trustworthy display unit. An LCD display would have been a better option.

The reviews for this product has been one with mixed feelings. It has about 166 reviews on Amazon and 3.8 out of 5- star rating which is a good one. Some of the users applauded the ability to provide excellent backup power for home appliances. However, one of the customers suggested that if you need to power larger motors, you should get a bigger unit. 


This inverter is a good choice and affordable especially if you do not have too much load to power. Personally, I would go for this inverter due to its affordable cost, USB ports and the number of AC outlets. To enjoy this unit, it is essential that you identify the type of loads your inverter will be powering and how much you will be using them between charges. Once you know how much power you will be using, you can determine how much battery capacity you need.
