What Can a 200-Watt Inverter Power?

Are you considering purchasing a 200-watt power inverter or already have one in your car or RV? Are you wondering what appliances you can use it for? Read on to find out what you can power with it and how to make the most of it.

Appliances That Work with a 200-Watt Inverter

A 200-watt inverter, when used correctly, can reliably power several low-power appliances while you’re on the move or enjoying outdoor camping.

Here’s what it can handle:

1. Single Appliances or Multiple Simultaneous Appliances:

You can connect a single appliance or several appliances at the same time, as long as their combined maximum power consumption doesn’t exceed 200 watts.

Additionally, the inverter should handle surge power draws of up to 400 watts (though this can vary by model, so consult the owner’s manual).

Examples of Appliances and Their Typical Power Consumption:

  • 32-inch TV (~40 watts)
  • Laptop (~40 watts)
  • LED lights, or Christmas lights (~40 watts)
  • Phones (~10 watts)
  • Mini fridge (~50 watts)
  • Tablet (~20 watts)
  • GPS units (~10 watts)
  • CPAP machine (~45 watts)
  • Pro Tip: Aim to run the inverter at up to 80% of its capacity and install it in a well-ventilated area for reliable performance.

Appliances to Avoid Connecting to a 200-Watt Inverter

Certain high-draw appliances are not suitable for a 200-watt inverter:

  • Space heaters
  • Microwaves
  • Electric kettles
  • Sandwich makers
  • Tire compressors
  • Coffee makers
  • Toasters

Note: Always check the appliance’s power draw before connecting it to the inverter.

USB Ports on a 200-Watt Inverter

Some 200-watt inverters come with USB ports (usually 5V, 2.4A) for charging phones and tablets.

Guidelines for Using a 200-Watt Inverter Safely

1. Check the Inverter Type:

  • Confirm whether your appliance requires a pure sine wave inverter or a modified sine wave inverter. Medical appliances and those with motors may not work well with the latter.

2. Stay Within Limits:

  • Ensure that the appliance’s power consumption falls within the inverter’s limits. Overloading the inverter can damage it.

3. Match Voltage Requirements:

  • Connect the right voltage to prevent damage to the appliance.

What Batteries to Use with a 200-Watt Inverter?

  • A 12V, 200-watt inverter will last about 1.5 hours on a fully charged 50Ah AGM battery (assuming 50% discharge).
  • LiFePO4 batteries, which can be discharged up to 80%, can last approximately 2.4 hours with the same setup.

ProTip! Aim to run the inverter to up to 80% of its capacity. Make sure it is installed in a well-ventilated area for it to perform reliably.
