Questions & Answers

Questions

  1. Can I run a basic 8 amp power drill with this unit

    1. 8 amps at 120 volts equals 960 watts of electric demand. I would not try to run that drill with this 750 watt inverter. It does not have enough capacity.

      Helpful?

    2. No, 8 amps would exceed the wattage rating of the Inverter (8 amps X 115 volts = 920 Watts). This inverter would probably power up a 2.5 amp. drill with no problem.

      Helpful?

    3. A drill that requires 8 amps of power will require a larger inverter. Our item number 4572000 shown below will provide the power your drill will require.

      Helpful?

  2. Amp output?

    I saw where an answer given sometime ago said the max amp output was 6.25. Since most of my tools are 7 amp. 10 amp. up to 15 amp. in some cases, would these tools be too much of a overheat or danger problem for putting too much amp pull on the inverter?

    1. Absolutely! You need an inverter rated for the load demand, plus sufficient overhead capacity to allow for the power surge demand when the tool is started. You also need to wire such a high load directly to the battery, avoiding the typical cigarette lighter outlet altogether. It cannot stand the heat generated by such a large load. You will blow fuses, and possibly melt wiring and could even melt the outlet housing.

      Helpful?

    2. This inverter has a max amp output of 6.25. Any tool that requires more than 6.25 amps cannot be powered by this inverter. The inverter will shut off as it has overload protection. Tools rated at 7 amps require an inverter rated at 840 watts or more. Tools rated at 10 amps require an inverter rated at 1200 watts minimum. 15 amp tools require an inverter rated at 1800 watts minimum. Click the links below to view inverters with higher wattage outputs.

  3. Safe for a laptop?

    1. I would not recommend a modified sine wave inverter to power a laptop or any other expensive and sensitive electronic equipment. I would use a "pure sine wave" inverter instead. They cost more, yes, but they output current that is almost exactly like the current you get when you plug into the grid at your house. This protects the laptop from damage. It is worth it, in the long run, to pay the difference in cost and get the "pure sine wave" inverter

      Helpful?

    2. The NPower Portable Inverter is safe for sensitive devices such as a laptop.

      Helpful?

  4. I am planning to draw approx. 300 watts. Would a 750 watt unit preform better than a 400 watt unit ? (not considering the cost)

    1. In general, either one would do what you want to do. The smaller inverter will operate at a higher temperature under that much of a load, but should still do the job. It may also draw less current just to operate the inverter as compared to the larger inverter. The larger inverter would not even be stressed at that 300 watt load level, so it should run cooler, longer. It also allows you some overhead - that is, extra capacity as needed.

      Helpful?

    2. Most likely using a larger inverter will be better. The closer to the capacity of the unit being used, the harder the inverter has to work. Using a 400 watt unit at 300 watts for long periods can eventually overheat the unit, and you would have to wait for it to cool down before using. If not using for prolonged periods of time, the 400 watt unit would not be a problem.

      Helpful?

  5. Do I need to turn the inverter off to prevent my car battery from draining?

    The assumption being that all plugged in items would be turned off.

    1. The inverter draws a bit of current just to function, and it draws that current all the time if it is plugged in and turned on. This occurs even if nothing is plugged into the inverter - assuming your inverter does not have an automatic "off" function built in. All inverters do this. The automatic "off" function simply turns the inverter off if there is no load drawing power from it. You do the same thing when you flip the off switch to off, or when you unplug the inverter.

      I would not leave the inverter plugged in when the car is not running, precisely because of the risk of draining your battery.

      Helpful?

    2. Always turn off the inverter when not in use to prevent slight discharge of battery.

  6. Can I use this inverter with stand alone deep cycle battery?

    Battery is Interstate 12 volt rv/marine type with caps. Can I use this setup in my house to power lamps,etc or is there a danger with battery fumes? Owner manual says not to put inverter and lead acid battery in a compartment which I wouldn't be doing because os the fumes. Thanks.

    1. Definitely. You can power many household devices using the 750 watt inverter. Connect this inverter directly to your battery. I understand a lead acid battery produces hydrogen during charging, so you are right to allow ventilation. Avoid ignition sources such as switches and heat-producing devices near the battery. Even though deep cycle batteries are sealed, you should not take any chances.

      Helpful?

    2. This NPower Portable Inverter can be used with a deep cycle battery. A battery has potential danger, it contains sulfuric acid and produces hydrogen gas as it discharges. Precautions should be taken to prevent spills and avoid sparks around the battery.

      Helpful?

  7. Can the AC outputs on 2 of these inverters be wired in parallel to double the watts - in this case 750W to 1500W ?

    1. Sounds like you are planning to add a 1500 watt hotplate to cook on or a electric iron. I would not add them even if it worked. Get a larger unit built for the proper size.

      Helpful?

    2. No, wiring these inverters together could damage the inverters. If you need 1500 watts the best option is to use a 1500 watt inverter. See link below for more details.

      Helpful?

  8. Does this come with a cable that plugs into a cigarett lighter

    I'm mainly looking for an inverter to run a small TV or small fan, will this be sufficient?

    1. Yes, get it. A small 40 watt TV or small 60 watt fan is the perfect item for this. Both at the same time. It will handle 750 watts. Just look on your device and add them up until you get close to 750 watts. A hair dryer or hotplate would not be smart. The damage comes when the inverter is a fried due to an overload.

      Helpful?

    2. This item comes with battery cables and must wired directly to the vehicle battery. This inverter should be capable of running either a small T.V. or a small fan, but probably not both at the same time. Be sure to check the power requirements of the items that you want to operate with this inverter before ordering. On the appliance there should be a tag or label that lists the amperage requirement.

      Helpful?

  9. what size inverter would work on a compact refrigerator

    1. look on your refrigerator for the UL label that tells you how many amps or how many watts the refrigerator draws when it is running. Then figure maybe 25% more to allow for the power surge needed to kick the refrigerator into operation when it first comes on.

      This inverter supplies 750 watts continuous power, or about 6.25 amps. I believe it will operate most compact refrigerators without a problem, but it is best to double check by looking at the UL label as I suggest above.

      Please remember, other electrical loads will also affect your inverter. If you are running lights and a television, etc, plus the refrigerator, you might NOT have enough power to do all that at the same time.

      Helpful?

    2. To determine the wattage requirement you'll need to use the formula amps x volts = watts. Northerntool.com has a generator buyers guide to assist in your wattage needs.

  10. Can this inverter be hardwired in by removing the battery clamps and wiring direct to the battery or a disconnect switch ?

    1 answer

    1. The NPower Portable Power Inverter would be capable of being hardwired directly to a battery or disconnect switch.
