Portable Power Station

Your YETI’s LCD display is an advanced feature designed to help you better understand power and monitor your consumption. The INPUT side reflects the amount of power your YETI is receiving while it’s charging. The OUTPUT side indicates the amount of power the devices you have plugged in are pulling out of the YETI – in the form of AMPS, VOLTS, WATTS, AMP HOURS and WATT HOURS. You can use the numbers displayed in WATTS to estimate runtimes. For example, if you have a light plugged in that is pulling 100W, you can estimate the YETI 400 will run the light for about 4 hours (YETI Wh/Device W = runtime in hours; 400/100= 4 hours). WATT HOURS (Wh) and AMP HOURS (Ah) represent the amount of power being pulled per hour. This number continues to accumulate with each use of your YETI and can be manually reset whenever desired.

When it comes to power, you might have heard the letters DC and AC thrown around. DC stands for Direct Current, and is the only type of power that can be stored in a battery. AC stands for Alternating Current, which is the type of power your devices use when they’re plugged into the wall. An inverter is required to change DC output to AC output and requires a small amount of power for the change. You can see this by turning on the AC port and looking at the OUTPUT on the LCD display. A pure-sine wave inverter, like the one found in your YETI 400, produces an output that is exactly the same as supplied by an AC wall plug in your house. Although integrating a pure-sine wave inverter takes more components, it produces power output that makes it compatible with almost all AC electric devices you use in your house. So in the end, the pure-sine wave inverter allows your YETI to safely power almost everything under 400 watts in your house that you would normally plug into the wall.

Plug your YETI into a power source, like a solar panel or outlet, as soon as possible. This chirping is to alert you that your YETI’s battery is low and needs to be charged.
