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 LED 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 for keeping
your devices charged on long flights.
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 multiple 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
50 to 50% full, then remove the fuse, and
store in a cool place.
