Power emergencies come to play in our lives in different forms every day. Ranging from low battery issues on our cell phones to powering your basic home appliances, the need for a power inverter which can serve as a reliable backup in this situation cannot be overemphasized. Bestek, which is Amazon’s leading power inverter brand, has a 2000W portable power inverter unit designed to power your major household appliances and electronics on the go. Bestek 2000W power inverter is durable and can stand harsh environments; ideal for use in campsites, RVs, remote job sites and anywhere that AC power is needed.


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.

The Bestek 2000W Power Inverter package includes these items: 2000W power inverter unit, 4 battery clamps, 1 cigar adapter and 1 user manual. Its features are stated 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 4600W 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 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.

LED Indicators

These indicators also work with the LCD to give you a status update of your inverter. A green LED indicates that the unit is on and receiving power.  Whenever a shutdown occurs due to an error condition, the green LED remains on.  A red LED indicates an error or alarm condition such as high voltage, low voltage, and voltage overload.

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.

Ultra-Silent Thermostatically Controlled Cooling Fan

The two small internal fans keep the unit cool while operating under heavy loads ensuring proper ventilation. These fans only come on when the temperature rises above the normal temperature range for this inverter.


Six external 50A Fuses

This safety feature not only protects your home appliances, electronics, pumps, and motors from damage, it also is a convenient replacement for fuses.

Low Voltage Shutdown

The LED illuminates RED, automatically shutting down the inverter when the battery voltage drops below 10±0.5VDC. This protects 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, automatically shutting down the inverter if the input voltage rises to more than 15±0.5VDC. This action prevents devices from getting damaged.

AC Overload Protection

The LED illuminates RED when the continuous draw or the surge draw of the equipment, exceeds the rated capacity. Following this action, the inverter will automatically shut down. 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.

NB: This inverter resumes work after the inverter has been restored to its normal working conditions.


The cost of this inverter, $139.99, is a good price for a modified sine wave inverter. It also has an 18-month warranty.

  • 6 external 50A fuses added for safety during use. This will come handy if you or any other person mistakenly overloads the system or there is a wrong connection.
  • It has 3 AC outlets which is more than other similar rated inverters. This is great because you will not need to have an extension to plug three appliances.
  • Near silent thermal fan and is therefore considered to be a quiet inverter.
  • The absence of remote port makes it impossible for you to operate the inverter with ease from a distance.
  • It does not have an LCD display unit which would have been a much better substitute for the LED lights.
  • It has no USB port which can be a problem if you forgot to bring your charger along while on a trip or at work.


For a modified sine wave inverter, this inverter has a lot of positive reviews. It has about 55 reviews on Amazon and 4.0 out of 5- star rating which is a good one. Most of the customers commended the ability of the inverter to efficiently run a garage and serve as a reliable backup. A few others complained about its inaccessible internal fuses, making it difficult for one to replace them.
