USB-C charging general info

Even though we tested the WOO 4.0 Chargers with as many USB-C chargers as possible, we cannot guarantee that it works with all available options. If you encounter an issue with your wireless charger, please try another USB-C charger. Also note that the WOO 4.0 Charger requires 1A of current at 5V, so many USB-C hubs or splitters may not provide enough power, particularly when coming from an USB-A port.

WOO 4.0 SHELF Mode

Shelf Mode LED clue

When the WOO 4.0 wakes up from SHELF mode, it blinks blue three times upon button press, and then goes back to the normal alternating green LED signal. That's your clue to connect the WOO to the App to set it's clock again.

WOO 4.0 features a mechanism to disconnect the WOO device from the battery when stored for a long time. Every electronic device consumes some current, even when switched off, to maintain the clock etc. When the WOO 4.0 reaches a certain charge level, and is stored and left untouched for longer than 15 days, it automatically goes into AUTO SHELF mode. It is the equivalent of unplugging your TV or microwave. This helps your WOO 4.0 to preserve it's battery charge to the best of it's ability, assuring that when you wake up your WOO in the spring and after a long winter, it has battery charge left. Most importantly, it prevents the WOO 4.0's battery to sit for long amounts of time in an empty state, which is not conductive for the WOO 4.0's Lithium Polymer battery.

WOO 4.0 discharge rate without SHELF: approx. 35% per month
WOO 4.0 discharge rate with SHELF: approx. 5% per month

❗️

Reminder - Set clock after SHELF mode

A side effect of SHELF mode is that the WOO loses it's clock. To set the clock after waking up the WOO from it's hibernation, simply connect it to the phone.
