Charging EnergyFlux
Make sure the unit is fully charged before first use or when it has not been used in a long
time.
• Turn off the hand warmer before charging.
• To charge, plug the micro USB end of the provided cable into the unit and the big USB end
of cable into a USB wall adapter (not included) or a device with USB port (ex.: computer). The
unit is most effectively charged when the provided charging cable is used with a USB wall
adapter/charger.
• The three blue LEDs show the remaining charge. When charging, each blue LED will flash
until all three are lit, indicating that charging is complete.
• Charging time is about 6 hours.
• To maximize the lifespan and capacity of the EnergyFlux’s lithium batteries, we recommend
charging the EnergyFlux at least every 3 months, even when not being used.
• Do not allow the EnergyFlux’s battery to remain low for extended periods.
• Store EnergyFlux in a cool, dry place to help.
NOTE: DO NOT CONTINUE CHARGING FOR MORE THAN 12 HOURS EVEN IF THE INDICA-
TOR LED CONTINUES TO FLASH EVEN AFTER THE EXPECTED CHARGING TIME.
