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.

Haven't used the product yet , however, the USPS did nice job of practically destroying the package and took it forever to get here. I would prefer ups or fed ex because it seems like they care.

  • Will the Power Inverter 1000 Watts with Three AC Receptacles Be Enough for a Coffee Maker
    The Power Inverter 1000 Watts with Three AC Receptacles part # WC3720 provides 1,000 watts of continuous power and 2,500 watts of surge power. These are the two figures you need to look at for appliance compatibility. This will be ideal for smaller coffee makers which produce around 2 cups of coffee. For 8-10 cups you'd need somewhere between 1,000 - 1,500 watts continuous so the Go Power Industrial Pure Sine Wave Inverter part # 34279950 would be a better option. That said you'd want to...

  • How to Use an AC Powered Air Conditioning Unit on a DC Powered Travel Trailer
    I do have a way for you to install an AC powered air conditioning unit on your travel trailer that operates on DC power but the 12 volt power circuit on the 7-way trailer connector will not be sufficient to power an inverter running a 10,000 btu air conditioning unit. A 10,000 btu air conditioner in going to require around 2,000 watts for startup and 700 watts of continuous power to run. These figures are averages and you will want to check your unit for exact specifications. If you will...

  • 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...

  • Can The Wagan Power Inverter # WC3720 Be Mounted In The Bed Of A 2020 Ram 2500
    The Power Inverter 1000 Watts with Three AC Receptacles # WC3720 can be mounted to the bed or bedrail of your vehicle but you will definitely want to ensure that your 2020 Ram 2500 has a good tonneau cover to prevent the inverter from getting wet. This inverter is designed to be within a foot of your vehicle's battery so your in-bed 7-way is not going to be enough to power the inverter so you'll need to run the wiring directly to the battery using 3 gauge wire to prevent voltage drop...

    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...

  • Wiring Wagan WC3720 Inverter to Two 12v Battery in Series
    If you actually mean that they're wired in parallel, where they're providing more capacity but still putting out 12v of total power, the Wagan 1000w Power Inverter # WC3720 will work for your application. If these batteries are wired in series, which would give you a 24v output you would need to go with a 24v power inverter similar to the GoPower Industrial Pure Sine 1000w # 34279949 . This inverter provides a GFCI outlet for added safety, in addition to the added voltage capacity. I'm...

  • Recommended Battery Charging Solution for 4 Snowmobiles In Trailer
    To answer your first question, not exactly; your 7 way trailer plug will have a 12v feed but it is only suitable for maintaining the trailer's battery and not actually providing a full charge. When it comes to charging the sleds, you're not going to want to directly charge them from the trailer battery and you will want to use a battery charger that is powered by the trailer battery. However there are two issues with this that will need to be taken into consideration. First, in order...

  • 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...

  • Powering Mini Fridge with 1000 watt Power Inverter
    The 1000-watt Power Inverter, # WC3720 that you linked to is a modified sine wave inverter capable of up to 1000 watts continuous, 2500 surge. You will need to check your appliance for how many watts are required for operation. 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). We can then best identify the needed size of a battery bank for operation. However, this type of unit is frequently...

  • Inverter to Use with Go Power Solar Flex Charging System with MPPT Solar Controller # 34275012
    The wattage output of the Go Power Solar Flex Charging System with MPPT Solar Controller # 34275012 is 550 watts so for an inverter that would handle that and work really well we have the Power Inverter part # WC3720 which is rated for up to 1,000 watts. We don't carry deep cycle batteries but the Group 27 batteries are a really great option for RV applications like yours and would work well with this setup as well.

  • Does a Refrigerator Need to Be Wired to an Inverter While Towing
    That is correct, Steven. You're going to need to wire an inverter # WC3720 to the trailer battery and then plug the fridge in while you're towing. It's also not a bad idea to throw a DC to DC battery charger # 331-BCDC1240D in to prevent the fridge from draining the trailer battery.

  • Will A 12V DC to 110V AC Converter Run A Coffee Pot?
    Using a 12V outlet like you mentioned, the Go Power Heavy-Duty Modified Sine Wave Inverter - 225 Watts - 12V # 34280173 will not be able to run most residential coffee pots without issue. Coffee pots draw a lot of power like up to 600-1200 watts on average at start up with a Keurig being closer to 1,500 watts, so you will need a much larger power inverter to use your trailer battery to power that coffee maker. I recommend the Power Inverter 1000 Watts with Three AC Receptacles # WC3720...

  • Inverter for my 2005 Ford E-250 Van Modified by Sportsmobile to be Camper
    The closest thing I have for that kind of power demand is the Wagan Power Inverter 1000 Watts with Three AC Receptacles part # WC3720. It produces 1000 Watts but not quite the 1200 you are looking for. I would use caution in doing this most of the time the cigarette lighter is not fused for that kind of power and a space heater will drain your battery fairly quickly potentially leaving you with out a way to start your rig. In this situation I recommend replacing the cover over the receptacle...

  • 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...

  • 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...

  • 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.

    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).

    I've attached a wire gauge chart for running your Power Inverter 1000 Watts with Three AC Receptacles Item # WC3720 to the battery. Roundtrip of that 17' distance to the battery would be 34'. Wagan only has recommendations up to 25' so anything after that would cause a significant power drop. I recommend cutting down that distance to ensure proper voltage. Failure to use the correct gauge wire could result in your inverter not supporting full loads and overheating and could potentially...
