Important Safety Instructions:

• Keep jump starter well ventilated. Ensure clearance around vents.
• Keep away from flammable fumes or clothing.
• Keep dry.
• DO NOT expose to rain or moisture.
• DO NOT operate if you, the unit, or any surface in contact with a power source is wet. Water conducts electricity.
• Do not place near heating vents, radiators, or heat sources.
• Do not place in direct sunlight. Ideal operating temperature: 50°F to 80°F.
• Do not use near open engine compartments where fumes may accumulate.
• Do not modify AC receptacles.

6.5 Using the Converter

Know the continuous wattage of the device. Use with devices drawing 400 watts or less. If wattage is not marked, use devices drawing less than 4.0 Amps AC.

Devices like TVs, fans, or electric motors require extra power to start ("starting" or "peak" power). The jump starter can supply a momentary surge, but devices rated less than 400 watts can still exceed surge capability and cause automatic shutdown.

Do not use with products drawing higher wattage than the converter can provide, as this may damage the converter and product.

Ensure the device is compatible with a modified sine wave converter.

CAUTION: Always test the converter with your equipment.

In case of overload, the converter automatically shuts down to prevent damage.

If powering multiple devices, start one at a time to avoid surge/overload.

IMPORTANT: If using the converter to power a battery charger, monitor its temperature for 10 minutes. If it becomes abnormally warm, disconnect immediately.

NOTE: An extension cord can be used from the converter to the device without significant power loss. For best results, extension cord should be no longer than 50 feet (15.24 meters).

IMPORTANT: This converter uses a modified sine waveform (Diagram A), which differs from pure sine waveform (Diagram B) typical of home AC outlets. Check device manuals for compatibility.

Using the converter with certain devices (e.g., switch mode power supplies, fluorescent lamps, microwave ovens) may cause them to run hotter or overheat.

6.6 Powering a 110V AC Device

1. Ensure battery clips are securely on storage holders.
2. Ensure the 110V AC device is turned OFF.
3. Plug the 110V AC device into the AC outlet on the back of the jump starter. Set the converter switch to "120V". The GREEN LED will light.
4. Turn the device ON.
5. If the device does not operate properly, try cycling the converter switch (ON, OFF, ON) quickly. If it still doesn't work, the converter may not have sufficient capacity.
6. To disconnect: Turn off the device, set converter switch to "O" (OFF), then unplug the device from the 110V AC outlet.
7. Recharge jump starter as soon as possible after use.

WARNING: RISK OF ELECTRICAL SHOCK. Converter output is 110V AC and can shock or electrocute like a household outlet.

110V AC Electrical Device Run-Times:

NOTE: Run-times are estimates and may vary. Based on a new, fully charged battery at room temperature.

NOTE: Maximum continuous load is 400 Watts. Do not use with products exceeding 400 Watts.

6.7 Converter Shutdown Protection

GREEN LED lights when converter is ON. RED LED lights and converter shuts down under these conditions:

1. Battery input drops to approx. 10.5 volts (low battery shutdown). Alarm sounds. Solution: Recharge jump starter.
2. Battery input exceeds 15 volts (high voltage overload). Solution: Reduce battery voltage to 12-14 volts.
3. Continuous load demand exceeds 400-watt capacity. Solution: Use a lower-rated device.
4. Case temperature exceeds 145°F. Solution: Allow converter to cool. Ensure ventilation. Reduce load.
