3.2 Charging the internal battery

Charge the unit as soon as possible after use. Never completely discharge the battery. Use a 2 A USB charger (not included), or a 2 A USB charging port to quickly recharge the booster. Using a charger with less than 2 A will increase charge time.

1. Plug the USB-C end of the charging cable into the input port. Next, plug the USB end of the charging cable into a charger's USB port.
2. Plug your charger into a live AC or DC power outlet.
3. The LCD display will light; the digit begins to flash and show "IN", indicating that charging has begun.
4. By using the 5 V DC, 2 A charging input, the booster will be fully charged in about:

SL472: 2.5-4 hours

SL473: 3-5 hours

SL474: 7-8 hours

1. When the unit is fully charged, the display will show "100%".

2. When the battery is fully charged, disconnect your charger from the outlet, and then remove the charging cable from the charger and the unit.

4. USING THE LED LIGHT

1. Press the display button.
2. Hold down the display button for 3 seconds.
3. Once the LED light is on (steady glow), press and release the display button to cycle through the following modes:

- Flash for an SOS signal;

- Flash in strobe mode

1. When finished using the LED light, press the display button until the light turns off.

2. Recharge the unit as soon as possible after each use.

5. CHARGING A MOBILE DEVICE

5.1 Charging with the USB ports

The booster includes two USB ports. One provides up to 2.4 A at 5 V DC; the other is a Quick Charge 3.0, which provides up to 5 V at 3 A, 9 V at 2 A or 12 V at 1.5 A.

1. Consult your mobile device manufacturer for proper charging power specifications.
   Connect a mobile device cable to the appropriate USB port.
2. Press the display button. Charging should begin automatically. The display will show which port is in use.
3. Charging time will vary, based on the mobile device battery size and the charging port used.

NOTE: Most devices will charge with either USB port, but may charge at a slower rate.

1. When finished using the USB port, disconnect the charging cable from your mobile device and then disconnect the charging cable from the unit. The unit switch OFF automatically.

2. Recharge the unit as soon as possible after each use.

NOTE: If no USB device is connected, power to the USB ports will automatically shut off after 30 seconds.

5.2 Wireless charging

The wireless charging pad provides 10 W of power to quickly charge your compatible mobile devices.

Consult your mobile device manufacturer to make sure your device supports wireless charging. Place the compatible device face-up on top of the charging pad.

1. Press the display button.
2. Charging should begin automatically. A symbol appears on the display.
3. When finished charging, remove your mobile device.
4. Recharge the unit as soon as possible after each use.

6. OPERATING INSTRUCTIONS

6.1 To start a vehicle

IMPORTANT:

• Using the booster without a battery installed in the vehicle will damage the vehicle's electrical system.
• Only jump start a 12 V lead-acid battery system vehicle.
• Only use the smart cable provided with the product for the jump start function.

NOTE: The internal battery must have a charge if at least 75% to jump start a vehicle.

Ignite OFF and all electrical devices (heating, lighting...) before using the booster.

Lay the DC cables away from any fan blades, belts, pulleys and other moving parts.

1. Connection to the booster - Stand-by mode

Plug the battery clamps smart cable into the booster's output socket. The green LED is flashing on the smart cable, which means that the booster is in "Jump Start Stand-by mode".

1. Connection to the battery

Check first if the negative terminal is connected/grounded to the chassis. If not, contact your reseller.

Connect the red clamp (+) to the positive terminal (+) of the battery, then connect the black clamp (−) to the earth/chassis of the vehicle (a heavy gauge metal part of the frame or engine block. Do not connect to the carburetor or fuel lines).

1. Jump Start mode

The green LED on the smart cable turn into solid green, which means that the booster is in "Ready to Jump Start mode".

NOTE: If the vehicle battery is extremely discharged, the initial current draw from the booster may activate short circuit protection in the smart cable. When the condition is corrected, the smart cable will automatically reset.

1. Start the engine

Crank the engine for maximum 3 seconds and wait at least 1 minute before a second attempt.

1. Disconnect the output cable

After the engine starts, unplug the battery clamps from the booster socket.

1. Disconnection

Disconnect the black clamp (-) at first and then the red clamp (+).

1. Recharging

Recharge the unit as soon as possible.

6.2 Starting attempt

When using the booster to start an engine, do not crank for more than 3 seconds, and wait at least 1 minute before a second attempt.

If the car does not crank a second time, check the smart cable to see if the green LED is lit (solid). If you hear beeping or an LED is flashing, refer to Troubleshooting.

NOTE: Cold weather may affect the performance of the booster's lithium battery. If you hear only a click and the engine does not turn over, try the following:

With the booster connected to the car battery and the green LED solid on the smart cable, turn on all lights and electrical accessories for one minute. This draws current from the booster and warms the battery. Now try to crank the engine. If it does not turn over, repeat the procedure. Extremely cold weather may require two or three battery warmings before the engine will start.

IMPORTANT: DO NOT attempt to jump start your vehicle more than three consecutive times. If the vehicle will not start after three attempts, consult a service technician.

7. MAINTENANCE AND STORAGE

After unplug and disconnect the unit, use a dry cloth to wipe all battery corrosion and other dirt or oil from the battery clamps, cords, and the outer case.

Charge battery to full capacity before storage. Charge at least once every month, if not in frequent use, to prevent over-discharge.

Store this unit at temperatures between -10^ and +45^ , in a dry place to protect it against humidity and moisture.
