Easily Power and Charge Electronics From Your Vehicle's Battery

Wagan 1,000 watt power inverter connected to battery

This mobile charging station is perfect for on-the-go families and business people. It connects directly onto your vehicle's battery so that you can charge your smart phone, watch movies on your portable DVD player, or plug in portable office equipment to take your work on the road with you. Following are examples of devices that can be used with the inverter:

  • Some laptops
  • Some TVs
  • Smart phones, tablets, and MP3 players
  • Small refrigerators
  • Coffee makers and blenders
  • Power tools
  • Portable lights

Safety Features

LEDs on the inverter indicate when it is working properly and when it isn't. A green LED lets you know that the inverter is plugged in correctly and receiving power. A red LED indicates fault with the inverter. An audible alarm sounds if the the voltage from your battery becomes too low, then the inverter will shut down. The inverter will also shut down if it overheats.


Wagan power inverter cooling fans

2 Cooling fans and an array of vents help prevent overheating of the inverter. You should only use the inverter in well-ventilated areas to help avoid overheating.


AC Outlets

Wagan power inverter ac outlets

The inverter has (3) U. S. standard 115-volt, 3-prong outlets. It produces a modified sine wave, which is suitable for most appliances and personal electronic devices powered by AC. Some devices - including laser printers, some laptops, and power tools that use solid-state power - may not work with a modified sine wave. Check the owner's manual for a particular device to make sure that device works with a modified sine wave before plugging the device into the inverter.


The inverter's USB ports are rated the same as any standard computer USB (5 volts). That means you can plug in your everyday USB-powered devices, such as MP3 players and tablets.


The USB ports do not support data communication - they can transfer power, not information.

  • How to Install the Wagan 1000 Watt Power Inverter # 02294
    The Power Inverter, # WC3720, comes with two 6-gauge wires with ring terminals and alligator clamps. They are only a few feet long. This inverter can be hard wired and the proper gauge will depend on how long you plan to run the wires. For example, if you will be running the wires 8 ft round trip, then you will want to use 6 gauge wire. If you will need 9 - 10 ft of wire, then you will need to use 4 gauge wire. If the cables will be running 11 -21 ft round trip, then you will want to use...

    To connect your Redarc In-Vehicle BCDC Battery Charger - Dual Input - DC to DC - 12V/24V - 40 Amp # 331-BCDC1240D, you will need the 60-Amp MIDI Fuse Kit for Redarc In-Vehicle 40-Amp BCDC Battery Charger # 331-FK60. This will protect your vehicle and battery from potentially damaging overcurrent from short circuits or overloads. You will run the Red Wire from your RedArc unit to the fuse, and then from the fuse to the positive battery terminal on your vehicle start battery. I've attached...

  • Finding The Right Power Inverter For A 1,500 Watt Accessory
    You just want to have a power inverter that provides at least 1,500 watts continuously so that your 1,500 watt steam cleaner will have sufficient power supply. The Power Inverter 1000 Watts # WC3720 that you were looking at only provides 1,000 watts continuously so you would be better off using something like Go Power Industrial Pure Sine Wave Inverter - GFCI - 1,500 Watt - 12V # 34279950 which supplies 1,500 continuous watts and 2,650 max surge watts.

  • Add Battery/12V System To Existing 120V System In Pop Up Trailer
    For the application that you are attempting, you will need to install a battery and wire the trailer to run off that battery instead of running off the shore power at a campsite. If all of your trailer lights and appliances run off of 120V then the 12 volt battery is not going to power them. you will need to add 12 volt accessories and lights to the trailer. If the trailer currently uses a converter from the shore power and the accessories and lighting run on 12 volts then you can run them...

  • Can Wagan Power Inverter # 02294 Power a Mini-Fridge in a Camper
    The Wagan Power Inverter # WC3720 that you referenced should be able to run your mini-fridge in your camper without any problems. To confirm this check your appliance for how many watts are required. If the wattage is not listed you can simply determine this number by multiplying the number of amps by the number of volts (amps x volts = watts). This inverter has a continuous power rating of 1000 Watts. I have attached a brief installation video as well as the installation instructions.

  • Determining How Long A 1000 Watt Inverter Can Power 400 Watts Of Electronics
    A 50 amp hour battery is only going to power 400 watts for approximately 1.5 hours so you would need to either have a larger battery bank or a way to recharge the battery. For a larger battery bank you'd really need something around 150-200 amp hours like the # PS64FR. This is pretty expensive so probably not the route you'd want to take just to power some computers. Recharging the battery would require either a generator or solar power, with the generator being the more reliable and...

  • Using a Refrigerator in a 2000 Mitsubishi Delica Van
    On a large 12 volt battery the vehicle alternator will not be able to charge it up. The best that it can do is provide a maintenance charge to the battery. You would then need to charge the battery using an AC charger such as # CTEK56353. A better option would be to use a fridge that plugs into AC power and then use an inverter such as # WC3720 which would connect directly to the regular vehicle battery. This inverter converts 12 volt DC power to 115 volt AC power. Provided the fridge...

  • Inverter For Powering Fridge While Driving to Campsite
    What you can do is use an inverter like you said, though this won't plug in, you will need to wire it from the 12 volt circuit on your trailer's 7-way. What you can do is use the Power Inverter 1000 Watts with Three AC Receptacles # WC3720. This has a power wire which you'll connect to your 12 volt circuit and a ground wire so you will need to make sure you are able to mount the inverter somewhere you can get a good ground. Otherwise, you would need to connect an inverter directly to your...

  • Recommended Power Inverter for 800 Watt Microwave
    For an 800 watt microwave you would need an inverter with power surpassing that surge max wattage. I recommend the Power Inverter 1000 Watts with Three AC Receptacles # WC3720 for that application which has a surge power of 2500 watts. You can run other items at the same time with this inverter depending on the wattage of those other items. If you want to be able to run multiple things with high wattage like a small refrigerator or coffee maker at the same time as the microwave, I recommend...

  • How to Add a Standard 110v Plug to a Truck
    I have a solution for you to plug your cooler in while you are traveling but there is no wiring harness that will provide you with a 110v outlet. Instead you will want the Wagan Mobile Power Inverter item # WC3720. The inverter connects directly to your Ram's battery and will provide three standard 115v outlets with grounds. This has a maximum continuous use wattage of 1,000 watts so it should easily be able to power your cooler. I have linked a review video below.

  • Can 12 Volt Batteries of Trailer Power AC Power Outlets
    AC power like what is found in a house is different from DC like the 12 volt battery setup you mentioned. Since you want to convert from DC to AC all you need is the inverter part # WC3720 that you mentioned. It would wire to the battery and then give you three outlets for the appliances you mentioned. I attached a review video for more info on this for you to check out as well.

  • How To Determine How Long A Battery Will Last When Powering A Portable Fridge
    Watts divided by volts equals amps, so 65 watts divided by 12 volts is going to equal 5.42 amps. Your battery should have an amp hour rating that you can divide by 5.42 amps and then you'll know exactly how long the battery can maintain the draw from the fridge. For example, the Go Power Lithium RV Battery # 34282738 has a 100 amp hour rating so you would get 18.45 hours out of the battery. That being said a fridge isn't going to constantly be running and depending on the climate you...

  • Determining The Smallest Battery Amp Hour Rating Needed To Run A 1400 Watt Coffee Maker For An Hour
    Watts divided by volts equals amps so 1400 watts divided by a 12 volt battery would be 116.67 amps. That would mean that you would need a battery with an amp hour rating of at least 116.67 amps to run your coffee maker for an hour. The closest amp hour rating we carry to this would be with the Power Sonic RV Lithium Battery # PS44FR, which has a 125 amp hour rating.

  • What is Difference Between Wiring Batteries in Series or Parallel
    What is the output voltage you are wanting? 12 volts? 18 volts? With battery banks if you wire them up in series the voltage of each battery gets added so you'd have 18 volts with 3 6-volt batteries and in parallel the voltage stays the same but the amperage increases.

  • Powering a Refrigerator in a Trailer While Towing
    Some items in a trailer or RV will run off of 12 volt DC power or AC power so if your fridge runs when not connected to shore power then it will run off of the battery. That battery can receive a maintenance charge from the 12 volt circuit on a 7-Way trailer connector but the fridge would draw power faster than the 12 volt circuit can charge. What you would need to do to provide the best charge to the battery is use a DC to DC charger while you are towing such as # 331-BCDC1240D. If the...

  • Recommended Way to Charge External Battery Using Tow Vehicle Battery
    Technically you could use a DC to AC converter like part # WC3720 with the CTEK MULTI US 7002 # CTEK56353 to charge an AGM battery. The only benefit of doing this though is having the ability to easily remove the CTEK charger and plug it into a wall outlet. Since the initial power is coming from the battery on your vehicle you would still get that trickle charge meaning your battery wouldn't charge at a fast rate. If you plan on leaving the CTEK converter on your trailer though then the...

  • Inverter Recommendation for Trailer Interior for Powering Lighting
    Do your interior lights power with 12 volts or are they AC power? Are you looking for an inverter to convert to 120 volts? We have inverters like the part # WC3720 which converts 12 volts to 120 which then gives you outlets for the lights to plug into if they are the standard interior style of lights.

  • How to Connect Series-Wired Batteries to Power Inverter
    When two batteries are wired in series, such as with your two 6V batteries wired together to give you 12V operation, the negative terminal on one battery and the positive terminal on the other will be what you connect to your inverter. The linked diagram shows a series wiring arrangement (but just for two 12V batteries wired to deliver 24V).

  • Can the Power Inverter 1000 Watts Part # WC3720 Pull 1000 Watts from Each Plug
    The Power Inverter 1000 Watts with Three AC Receptacles part # WC3720 can only pull 1000W of continuous power at a time between all three plug-ins. Therefore if you have a device that is pulling 1000 continuous watts of power at a time plugged into one of the slots then the other two slots can not be used. I have attached a review video of this product for you.

  • How to Charge an Extra Battery in the Truck Bed on My 2012 Chevrolet Silverado While Driving
    The best option would be to use the NOCO Genius # 329-GENIUS5, and charge the battery when shore power is available, or use the charger in conjunction with an inverter part # WC3720 when the truck is running. If you wanted to use the factory 7-way you could use the 12-Volt Power Inverter Adapter, # HM11147650, to provide DC power to the inverter. If the DC outlet in your truck is ran directly off of the trucks charging system, then you could use it to maintain a battery that is fully charged...

  • Are Power Inverter With Continuous Power Modified Sine or Pure Sine Wave?
    Continuous power does not mean modified or pure sine wave. If you have a specific model you are looking at, I can help further. For instance, the Power Inverter 1000 Watts with Three AC Receptacles # WC3720 says continuous power and is a Modified Sine Wave AC Output waveform. Some of the sample applications are even confusing as they are often used as Pure Sine wave applications, but based on the size are adequate.
