Best Power Inverter Reviews for 2000 watt units

What to look for when choose the best power inverter of 2000 watts:

What a power inverter does is to convert 12V DC power from a battery into conventional AC power that you need to use to operate devices such as electric lights, kitchen appliances, microwaves, computers, TV and etc. Usually, you connect the inverter to a 12 Volt battery(preferably deep-cycle). Now, you have a portable power wherever you need it. You might have been looking for the best 2000 watt power inverter for your home, car or RV. Here we reviewed a few most popular 2000+ watts inverter to help you find your ideal inverter.

Critical specs when shop your 2000W inverter:

1. Wattage

There are two types of power rating. One is called continuous power wattage. This is the power wattage a device needs during its normal operation. On the other hand, the peak or surge power wattage is the transient power when the device just gets turned on. Usually the peak power is twice as much as the continuous power. However, some appliances with a motor require very high surge power to start up. Some people call it starting load or peak load. Once started, it requires less power to continue to operate. Induction motors such as  refrigerators, pumps and air conditioners, may have a start up surge of 3 to 7 times of their continuous power rating.

2. Efficiency

This is very important to the high power inverter. Usually, most of 2000 Watts inverters have efficiency of 85% or higher. Why inverter efficiency is important. Two pieces to it. One, as mentioned, what an inverter does is to convert DC power to AC power. the more efficient it is, the less power it loses during the conversion. It saves your money. Second, the power it lost will turn into heat that will heat up the power inverters, which is always a bad thing. So, if you see an 2000W inverter has less than 80% power efficiency. You had better just pass it.

3. Protection Mechnisim

Power inverters have all kinds of the protection mechanisms to protect themselves during fault conditions. Here are a few of them.
Short Circuit Protection: if the inverter output is short to ground. It will shut down until the short is removed.
Low Voltage Alarm: when the DC power voltage is too low, the power inverter may issue a warning or turns off the unit.  It indicates that the battery needs to be recharged.
Over Voltage Protection: if the DC battery voltage is too high, in order to protect the inverter it will turn itself off.
Under Voltage Protection: the inverter turns itself off when the input voltage is too low.

4. Real customer reviews

To check out customer reviews of the products you plan to buy internet is always a good idea. Often, these reviews are written by consumers that used and passionate about the product. You can learn a lot about the product from their comments and reviews.

We list them up in the above table. But, let us briefly introduce these three inverters.

2000W WHISTLER power inverter

It has 2000 Watts continuous power and 4000 Watts Surge Capacity or Peak Power. It has 3 AC Outlets and 2 USB Port, along with Digital Watt Meter and Battery Volt to monitor input volts and output watts.

The AC output of inverters range from 110~120 volts. It has thermostat-controlled cooling fan that is activated with temperature. One thing you need to notice is that reverse polarity will blow the internal fuses in the inverter. That could cause permanent damage to the inverter. That damage is not covered under its warranty. So, just watch out. WHISTLER xp2000i  is capable of delivering 4000W peak power that is handy if you run the application with inductive motors which require high surge power, usually 3 to 5 times of their regular continuous power rating.


ENERGIZER 2000 Watt Power Inverter

It provides 2000W continuous / 4000W peak power capability. Its display offers input voltage and output wattage reading.

Cobra 2500 Watt unit delivers 2500 Watt continuous power and 5000 Watts peak power. It offers 3 AC outlets – Powers up to three or more household appliances and one USB port for charging. You can read its Volt/Watt meter  to keep track of power usage. Its Pentagon Protection(TM)  includes thermal shutdown (if the unit is too hot, its shuts down), over-voltage shutdown, low voltage shutdown and low voltage alarm, short circuit protection and also reverse polarity protection.

Tips: For the cable size, usually #2 gauge wire is required while in many cases #0 gauge is recommended.  If the cable size is too small or too long, it will keep the inverter from kicking off.


So, what is the best power inverter of 2000 watts on the martket? The answer is it depends. If you a loyal fan of ENERGIZER, you will not be disappointed this time. It does what it says. Cobra 2500W inverter could be best bet in terms of the surge power. Here, we reviewed three 2000+ watt power inverter on the market. Hope it helps you decide to pick your inverter.
