I recently purchased an IcyBreeze Portable Air Conditioner and Cooler for an upcoming camping trip. I want to run it on low for two nights, or about 16 hours. With this in mind, I purchased the following portable power source
The capacity is advertised as 42000 mAh.
The IcyBreeze page indicates the amp draw is 1.0 A on low.
This battery life calculator suggests I should get about 29.4 hours of battery life (using 42000 mAh capacity, 1000 mA draw, and the consumption rate of 0.7).
With a fully charged power source, I plugged the cooler in using the wall adapter, set it to low, and ran it until it stopped. I only got about 5 hours of battery life - far less than what I was expecting.
Clearly I am misunderstanding something about the battery life calculation. So I guess I have two questions:
- How can I more accurately estimate battery life for this setup?
- A little off topic, but the portable power source is still well within the return window, and I an open to alternative suggestions for how I might get 16 hours of battery life with a portable power source (non-generator).
