How do I know the Sherpa is turned on? Push the power button below the LCD batter monitor and it will light up.
How do I know if I have a full charge? The LCD battery monitor displays charge level in 20% increments. If all areas are shaded and the top segment says “Full” then it is charged up and ready to go.
Is the Sherpa waterproof? No. Although the Sherpa 50 is durable, you will want to protect it from elements. Make sure the ports are dry before using the device.
Can I take the Sherpa on an airplane? Yes, the Sherpa meets all requirements for carry-on and is perfect for keeping your devices charged on long flights. Please check with airline for current regulation.
How long can the Sherpa hold its charge? It can hold its charge for several months. However, to keep the battery healthy and ready to go, we recommend that you leave your Sherpa plugged in between uses. If this is not possible, charge it every 3-4 months.
What type of battery is used in the Sherpa? Lithium-ion NMC. It has these advantages: stores more energy; smaller and lighter watt for watt; and retains its charge even after months of storage.
Can I chain multiple Sherpas together? Yes. You can chain two Sherpas together through the sidecar port. See video for details.
Why did the Sherpa 50 turn off automatically? The Sherpa 50 has a built-in feature that turns the unit off after a period of inactivity. This saves power. To override this mode and keep it in “always on” mode, simply hold down the power button for about 10 seconds. A small “ON” icon will appear in the upper left side of the LCD battery monitor if you are in “always on” mode. In this case, it will only turn off if it runs out of power or you turn it off.
