7.2 CHARGING THE INTERNAL BATTERY
NOTE: Use a 1A USB charger (not included) to recharge the jump

restrict the ventilation in any way.
2. Connect the micro USB end of the charging cable to the micro USB port
on the end of the unit. Insert the USB end of the cable into the USB port
on your charger.
3. Plug your charger into a live power source.
4. The LED will indicate the charge level, as follows:
• Red LED flashing: ≤ 50% power
• Green LED flashing: > 50% power
• Green LED lit: 100% power
5. Charging may take 6.5-15.5 hours, depending on the battery level
and model type.
6. Recharge the unit after use, and at least every 3 months.
