PRO TIPS
Q: What battery types can be used?
A: Any AA or AAA NiMH rechargeable batteries can be used
and recharged. Four same-sized batteries must be inserted
for use.
Q: How do I charge?
A: From solar: use Goal Zero Nomad Solar Panels with
included USB-A to USB-C cable.
From USB: use any USB power source like a wall
adapter or computer.
Q: Is the Guide 12 waterproof?
A: No, but it is weather-resistant. Care should be taken to
shield it from direct sunlight and the elements.
Q: How is it protected?
A: Usage is plug-and-play. The built-in battery
management system prevents over-charging and
over-discharging of batteries. The USB output will only supply
the amount of power needed.
Q: Why is only one LED light displaying?
A: When a battery is replaced in the unit it will only show
one LED until the unit is fully recharged. Then when
discharging the Guide 12 you are able to press the button
to see if 1,2,3, or 4 lights are showing to determine how
much capacity is left.
Q: Why isn’t the Guide 12 charging my device when I
plug it in?
A: Try pressing the BATT CHECK/LIGHT button to initiate
charge. Confirm that the Batteries in Guide 12 are oriented
correctly and fully charged.
Nickel Metal Hydride (NiMH) batteries often will need to be
cycled 3-5 times to reach peak performance and capacity.
To get the most out of your NiMH batteries keep them
charging when not in use and cycle them every 3-4 months.
Use certified cables for the device you are charging.
For larger devices like cell phones we recommend using AA
batteries. They have more capacity then AAA batteries.
