Frequently Asked Questions
Q: How do I know if it is turned on?
A: Push the white power button below the LCD battery monitor and it will
light up.
Q: How do I know if I have a full charge?
A: The LCD battery monitor displays charge level in 20% increments. If all
areas are shaded and the monitor says “FULL”, then it is charged up and ready
to go.
Q: Is it waterproof?
A: No. Although the SHERPA is durable, electricity and water don’t mix well.
Make sure the ports are dry before using the device.
Q: Can I take the recharger on an airplane?
A: Yes, The Sherpa is perfect to keep your devices charged on long flights.
It is TSA compliant. There is a MSDS available online if you have further
questions regarding the contents of the Sherpa.
Q: How long can the Sherpa 50 hold its charge?
A: 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 50 plugged in
between uses. If this is not possible, charge it every 3-4 months.
Q: What type of battery technology is it?
A: 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.
Q: Can I chain multiple Sherpas together?
A: Yes. You can chain two Sherpas together through the sidecar port. Contact
goalzero.com for the chaining cord.
Q: Why did it turn off automatically?
A: The SHERPA 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.
Note for Extreme Users: Long Term Storage: For long-term storage (up to a
year), charge the Sherpa to 50% full, then remove the fuse, and store in a
cool place.
