What Can You Run on a 2000 Watt Generator?

2000 watt generators are a very popular class of power generators, featuring acceptable price, long runtime on a single gas tank, quiet operation, simple maintenance etc., and are thus often used for camping, boating, fishing trips, in RVs, etc. Also, they are often used in emergencies.

Thus, many people wonder what household appliances their 2000 watt power generators may run and for how long.

2000 watt power generator 1

Before trying to figure out what will 2000 watt power generator run, it is important to explain a few things about power generators.

- Running vs Starting Power: All power generators feature running and starting power - running watts represent continuous power that the power generator is able to provide, while starting power is the maximum power that the power generator is able to provide for short periods of time. This is very important for appliances, tools, devices, gadgets, and similar loads with electric motors that draw much larger currents when they start than during the normal operation.

When trying to figure out what will a power generator be able to power, always calculate using both running and starting power - it is easily possible that the generator is able to power all required devices during normal operation, but stopping and starting just one appliance with an electric motor can cause generator overload and its automatic shutdown ...

- Inverter Generator vs. Standard Generator: Standard power generators must operate at the pre-set speed in order to maintain the required frequency. For example, in order to provide electricity at 60 Hz, such generators operate at 3600 rpm, even with no load. On the other hand, inverter generators feature complex electronics based on AC and DC converters (also known as 'inverters', hence the name) that provide pure sine 60 Hz electricity with very low Total Harmonic Distortions (THD), making them suitable to power even sensitive electronics directly. Since inverters don't require 60 Hz input to provide 60 Hz output, the generator's engine may be throttled down when there is no load, or when the generator is lightly loaded, leading to increased fuel efficiency.

- Eco vs Standard Mode: Eco mode of modern inverter generators increases fuel efficiency, but may be of a problem when there are appliances and tools with strong electric motors - in Eco mode engine is throttled down and in order to provide enough power due to the power surges, the engine must be throttled up, and that requires time.

If your inverter generator is in Eco mode and it shuts itself off whenever there is an appliance or a tool with electric motor turned on, turn off the Eco mode and try to start that appliance/tool. If the appliance/tool features starting power lesser than the starting power of your power generator, it will/should operate normally. If not, check your power generator for error codes/statuses and let it cool down a little bit.

As one can see, the starting power of many tools and appliances is often significantly larger than their running power.

For example, portable inverter generator with 1800 running watts and 2200 starting watts is able to power:

- Window AC 10.000 BTU (~1200W/1800W) - after staring of AC unit, some 600 watts remain for powering lights, charging laptop/cell phones and other devices that don't feature electric motors. Or, just power the AC unit for longer operating time on a single gas tank.

- Toaster (900W), Microwave Oven (600W) - both units require some 1500W which should not be a problem for the 1800W/2200W power generator. But, if you try to start the blender (300W/800W), its starting power may trip automatic shutdown of the generator due to the overload (2300W vs 2200W) - this 100W difference isn't large, but it may cause the overload event.

- Coffee Maker (1000W), Deep Freezer (500W/1500W) - while you are making coffee, you try to start your deep freezer, causing an overload event (2500W total). This can be avoided by turning the deep freezer on first (1500W starting power, 500W running power) and coffee maker second (1000W running power).

But, be very careful when powering freezers and similar appliances - when freezer or refrigerator achieves required temperature, they turn themselves automatically off. When their internal temperature reaches a certain level, they automatically turn themselves on (calculate starting power) often causing overload events and automatic shutdown of power generators.

There are many possible variations of the appliances, tools, and devices in general that may be powered by 2000W generators.

The first thing to do is to write down actual starting watts and running watts of your power generator and to make a list of your appliances with their starting/running watts and do some math.

Again, some appliances with motors turn themselves automatically On and Off, possibly causing overload events.

How to Increase Output Power?

2000 watt power generator 2If you are having issues with your 2000W generator, the simplest thing is to get a new stronger/larger power generator. Although this method is probably the simplest, it is not always the most cost-effective method.

Most modern inverter generators come with the so-called 'parallel connection' feature, allowing the two same (or similar enough) models of the same manufacturer to be connected with the parallel connection cables in order to increase (double) output power.

Thus, if your 1800W/2200W portable generator comes with a 'parallel connection' feature, getting another 1800W/2200W portable generator (same model, same brand) with parallel connection cables (or parallel connection kit) is cheaper than buying the brand new 3600W/4400W power generator.

Also, don't forget the fact that you are already familiar with the 1800W/2200W power generator model that you already have.

2000W inverter generators class is a very popular generator class, featuring models that are rather compact, robust, and reliable, and that come at affordable prices.

If you need a stronger model, first check if your current power generator supports a parallel connection to the same (or similar) power generator.

Note: even very small power generators and power stations provide electricity at voltages and currents that may cause significant damage, and that can injure or even kill people. Whatever you do, read the instructions/manuals and if unsure, call/contact/ask for professional help, either locally or from the generator's manufacturer.
