EZ Watts
I first had the idea for EZ Watts when I was converting a cheap minivan into an off-grid camper. I needed a portable power station and I was having trouble estimating how much power I would need to run different appliances.
I learned how to calculate the watts needed for exactly how long each device would be powered on. But some devices (like 12-volt refrigerators and USB fans) would be on all the time, while others would be used for only a few minutes (like a water kettle or a microwave). It was confusing trying to keep track of all the numbers and what they meant.
So I created a really simple amps/watts/volts calculator on my website. This let me quickly get the numbers for a single appliance - but I couldn't save it and I could only do one at a time. So the idea of EZ watts 'the mobile app' was born.
I needed to create a mobile app to save all my devices, let me input a specific power station and to do all the calculations for me (and you). That's EZ Watts in a nutshell: make it easier to use appliances off-grid by estimating how long the battery will last when using those devices.
