RECHARGE

IMPORTANT

• Make sure that your battery charger is set to the proper voltage setting before recharging. (FIG. 1 & 2)
• Charge your Power Tank before using the first time.
• Always make sure the switch is “OFF” when not in use.
• Never attempt to use the battery charger provided for other products. (Fig. 4 or 5).
• If yellow LED light is on during operation, battery is weak and should be recharged. (FIG. 7)
• It is not recommend to use continuously when yellow LED light is ON, do not use in this condition and recharge immediately.
• Do not exceed recommended charging times. Explosion hazard exists if you do not follow this instruction sheet.
• Do not expose to extreme heat, flame, rain or moisture. (FIG. 3)

WARNING: Continuous use when the battery is low will damage the battery and may affect the ability to recharge your power tank.
HOW TO RECHARGE
AC RECHARGING

• Select the suitable adapter plug for the AC adapter (FIG. 7). Make sure that the plug is completely locked in the adapter.
• Push the main switch to the “CHA” position (FIG. 6) and insert the small end of the proper AC adapter into the charge input jack located on the FRONT PANEL of Power Tank. (FIG. 8)
• Plug the charger into an appropriate electrical outlet. (FIG. 1 to 5&9). The RED recharging light should come “ON” indicating the battery is recharging. (FIG. 8)
• Charge the battery for 14 or 16 hours before initial use. After the initial charge, subsequent charges will only be 8-10 hours (approx). If the unit is used too long after the yellow light comes on, recharging could take up to 20 hours.

DC RECHARGING

• The DC recharging adapter is located in the compartment on the back side of the Power Tank.
• Push the power switch to the “CHA” position (FIG. 6) and insert the provided DC recharging adapter into the charge input jack located on the front panel of Power Tank. (Fig. 8)

STORAGE

• High Temperature above 40°C should be avoided.
•  It is important to store the Power Tank in a clean, cool and dry place. Radiant heat such as sunshine, heating units, radiators or steam pipes will shorten the life of the Power Tank.
• For longest life, Power Tank should be fully charged before going into storage. The Power Tank stored at 10°C or lower should be recharged at least once per

•  Insert the other end into the cigarette lighter and rotate to receive a good electrical contact. (Fig. 10) The red light should come “ON” indicating the battery is recharging (Fig. 8). Use DC 12V negative ground system only.
• The Power Tank should be charged for 5 to 8 hours (The charging rate will be 14.5 volts to 15.5 volts) while driving before initial use. After the initial charge, subsequent charges will last only six hours (approx.).

NOTE: Charging the battery while the car engine is not running is not recommended as it drains the car battery. Engine must be running and the charging system functioning properly in order to initiate a charge. The ideal charging rate is 14.5 volts to 15.5 volts, nearly identical to the charging system in most vehicles. If the unit is used too long after the yellow light comes ON, recharging can take up to 8 hours.
WARNING: Don’t plug in the cigarette light plug and charge the unit without starting the engine. This may destroy your vehicle’s battery. Always recharge in an open area, otherwise explosive gas may generate during overcharging.
six months. The Power Tank stored at 10°C TO 27°C should be charged every 3 months and recharging should occur every 45 days in temperature from 27°C TO 40°C. The storage battery discharges automatically when the Power Tank is not used for a long time.

•  Make sure the Power Tank IS “OFF” before going into storage.

• Connect the POSITIVE pole (+) of the Power Tank to the POSITIVE pole (+) of the vehicle battery.
• Connect the NEGATIVE pole (-) of the Power Tank to the NEGATIVE pole (-) of the vehicle battery.
• Leave the Power Tank connected to the vehicle battery for around 20 minutes.
• After approximately 20 minutes, disconnect the jumper cable from the NEGATIVE pole (-) of the vehicle battery.
• Then disconnect the jumper cable from the POSITIVE pole (+) of the vehicle battery.
• This partial charge should be sufficient to start the vehicle.
• The Power Tank needs to be recharged after using as a starting aid.

WARNING: The Fuse and Switch is no function on the connect ( + ) ( – ) pole, current flows directly from the battery, Once the jumper cables are connected, NEVER allow the cables to touch together or be left on the same metal surface, this will result in short circuit and may start a fire.
