Operating Instructions

Jump-Starting a Vehicle Engine

WARNING: Failure to follow instructions may cause damage or an explosion. Read entire instruction manual before use. Always shield eyes during use and wear safety glasses.

Use in a well-ventilated area. Keep hands, hair, clothing, and jewelry clear of moving engine parts.

1. Turn the vehicle ignition OFF before making cable connections.
2. Rest the 1150 on a flat, stable surface near the vehicle battery and away from moving engine parts.
3. Connect the red clamp to the positive (+) terminal of the vehicle battery.
4. Connect the black clamp to an unpainted and unmoving part of the vehicle chassis or engine block.

   CAUTION: If you have connected the clamps backwards, an audible alarm will sound. Reverse the connections, and the audible alarm will stop.

5. Digital Display Check:
   • If the display remains blank after steps 1-4, check clamp connections.
   • If the display still doesn't light, hold the display switch for 5 seconds.
   • If the display doesn't blink, the vehicle battery voltage is too low (below 0.5V) and needs charging before the 1150 can jump-start it.
   • The display will show the vehicle's battery percentage for 5 seconds.
   • Then, it will blink to indicate proper connection and show the combined charge percentage of the 1150 and the vehicle battery.
   • If the combined percentage is below 35%, the 1150 needs charging.
   • If the combined percentage is above 35%, proceed to step 6.
6. Turn the vehicle key and crank the engine. The display will count down from 10 seconds.
7. If the engine does not start, wait at least 1 minute before attempting to crank again to allow the battery and relay to cool down. Only attempt to crank when the display is blinking (relays engaged).
8. Once the engine starts, the 1150 will automatically shut off 10 seconds later to prevent sparking when removing clamps. Remove and store the clamps on the designated ears on the back of the unit.
9. Charge the 1150 as soon as possible after jump-starting.

CAUTION: To prevent sparking, NEVER allow the clamps to touch each other or the same piece of metal. Never attempt to charge a frozen battery.

NOTE: For vehicles with a positive-grounded electrical system, connect the black clamp to the negative terminal of the vehicle battery and the red clamp to an unpainted, unmoving part of the vehicle chassis or engine block. Consult the vehicle's owner's manual if unsure.

Before Using the Inverter

Important Safety Instructions:

• Keep the inverter well-ventilated; ensure clearance around the top and sides, and do not block rear vents.
• Keep the unit away from flammable fumes, gases, or clothing.
• Keep the 1150 dry. Do not expose to rain or moisture.
• Do not operate if you, the unit, or any connected surfaces are wet. Water conducts electricity and can cause serious injury.
• Do not place the unit on or near heating vents, radiators, or other heat sources.
• Do not place in direct sunlight. Ideal operating temperature is 50°F to 80°F.
• Do not use the inverter near an open engine compartment.
• Do not modify the AC receptacles.

Using the Inverter

Know the continuous wattage of the device you plan to use (400 watts or less). If wattage is not marked, estimate by multiplying AC input current (Amps) by AC voltage (110V).

Devices like TVs, fans, or electric motors require higher "starting" or "peak" power. The 1150 can supply a momentary surge, but devices rated below 400 watts can still exceed surge capability and cause shutdown.

Ensure your device is compatible with a modified sine wave inverter.

CAUTION: Always test the inverter with your equipment first.

NOTE: In case of power overload, the inverter automatically shuts down to prevent damage.

NOTE: When powering two AC accessories, their combined wattage must not exceed 400 watts.

Powering a 110V AC Device

1. Open the protective cover of the AC power outlet on the front panel.
2. Plug the 110V AC device into the outlet and push the inverter switch to ON.
3. Turn on the 110V AC device (if required).
4. If a device does not operate properly, try toggling the inverter switch ON (I), OFF (0), and ON (I) quickly. If it still fails, the inverter may lack the required capacity.
5. Charge the Portable Power 1150 as soon as possible after each use.

CAUTION: Incorrect inverter operation can cause damage and personal injury. 120-volt circuits are dangerous.

110V AC Electrical Device Example Run-Time Chart

The maximum continuous load is 400 watts.

*NOTE: Estimated run-times. Actual time may vary. Times are based on the internal battery being fully charged.

Troubleshooting

The digital display will flash "Err" and the inverter will automatically turn off when:

1. The input voltage from the battery drops to approximately 10.5 volts (an alarm sounds around 11 volts).
2. The continuous load demand exceeds 400 watts.
3. The inverter temperature exceeds 145°F (63°C).

NOTE: A cooling fan runs for loads of 25 watts or higher. If the fan cannot maintain a safe temperature, the inverter will shut down.

If the inverter automatically shuts down or a continuous audible alarm is heard:

1. Push the inverter/compressor switch to the OFF position.
2. Determine and resolve the source of the problem before reusing the inverter.

Digital Display Functions

1. Portable Power 1150 Status: Press the display switch to check the internal battery's charge percentage.
2. Vehicle Battery Status: For the first 5 seconds, the display shows the vehicle's battery power percentage.
3. Vehicle and Portable Power 1150 Combined Status: After 5 seconds, the display blinks and shows the combined total starting power of the vehicle and 1150 batteries. You have 10 seconds to attempt to start your vehicle. The display shows a 10-second countdown, then a 60-second countdown. This cycle repeats until no power is left in the Portable Power battery. (See Page 4 for further details).
4. AC Power Status: When using the inverter, the display shows the 1150's battery percentage. When clamped to an external battery and the inverter is on, it blinks and shows the combined power level of both batteries.

Charging the Internal Battery

This Portable Power 1150 uses a sealed, non-spillable, maintenance-free lead-acid battery designed for high power jump-starting and deep cycling.

To charge the internal battery:

1. Check the internal battery's charge level by pressing the DISPLAY switch.

NOTE: Display accuracy is best after the unit has been disconnected from devices and charging sources for at least 30 minutes.

2. Using a proper extension cord, connect it to the charge plug and then to a properly wired 110Vac/60Hz wall outlet.

CAUTION: Operating the unit while the internal battery is charging may cause permanent damage.

3. While charging, the battery's percentage of charge will be displayed. When fully charged, the display will show 100. Complete charging may take up to 72 hours. If an error occurs, "CH9 Err" will be displayed.
4. Once fully charged, the built-in charger switches to float-mode monitoring, trickle charging to maintain full charge without overcharging. The unit can remain connected to the wall outlet.

The internal battery can also be charged while driving using the included male-to-male accessory cable. Connect one end to the 12V DC power outlet and the other to the vehicle's accessory outlet (lighter socket). Disconnect the cable when the engine is not running.

Storage and Maintenance

Charge the 1150 internal battery before first use and after every use.

The internal battery self-discharges over time, especially in warm environments. Leaving it discharged can cause permanent damage. For optimal performance and to avoid damage, charge the internal battery every 2 to 3 months. The unit may be left permanently connected to the AC wall outlet. Store in a cool, dry place.
