What is "Always On" Mode?
There are times when you want your battery to stay on whether or not there's any power draw. With an Always On battery, you could power GPS tracking devices, perform time-lapse photography with GoPro and other cameras, or run Arduino and Raspberry Pi. Essentially, if you want to power a device over several days, weeks, or months without human intervention, then the Always-On Mode is a good fit to power your devices.
When shipped, most of our batteries are in Auto Off Mode. They are designed to shut themselves off after about 20 minutes of little or no power draw. This will usually occur if the device they are charging is full or is disconnected from the battery. To re-activate the output, the power button on the battery must be pressed. This helps conserve power in the battery.
