Cool Tools: Kill A Watt measures watt/amp draw

Every Wednesday (except this Wednesday!) we meet for a livestream called, Talkin’ RV Tech. We not only answer technical questions, but we also share what we like to call “cool tools.” These are tools and gadgets that we actually use! We also believe they will be helpful to you.

Here’s a clip of one of our latest videos where we discuss the Kill A Watt™ EZ Electricity Usage Monitor.

This gadget is extremely useful when checking how many watts or amps a particular appliance draws. It even works for small appliances such as a toaster, coffee maker, hot plate, air fryer, or hair dryer.


Whether you are parked at a campground and plugged into 30 amps or you are wanting to build an off-grid system for dry camping, managing your energy usage will be the key to your success.

To use this gadget, you plug the Kill A Watt into an AC wall outlet and then plug in the device you want to measure. It reads out Amps, Watts, Volts, Hertz and Kilowatts per Hour. In the video’s example, Dave tested a heat gun. That heat gun was using 11 amps to run. While most people won’t be running a heat gun while camping, it is comparable to a small ceramic heater that is commonly used.
