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.

See what our Experts say about this Wagan 12V Power Accessories

  • Recommended Vehicle 7-Way to 12v Plug Adapter
    To turn the 7-way on your truck into a 12v power source you will want to use the Pollak 7-Way to 12 Volt Power Outlet Adapter item # PK11896. This will plug into a 7-Way on your vehicle and provide a 12V plug on the other end that can be used with 12V accessories. This adapter can handle a 20 to 30 amp power draw but the limiting factor will be if the 7-Way on your truck is rated high enough as well. You will want to check the fuse for the 12 volt circuit for the tow package trailer connector...

  • DC to AC Adapter Solution for Utility Trailer to Power Portable Power Station
    You'll need an inverter to go from 12 volts to 120 volts AC power like the Wagan Mobile Power Inverter part # WC3720. Since this has multiple outlets you can use it to power your charge station or power additional AC appliances 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...

  • Powering A Small Fridge While On A Boat
    To charge the battery while the boat is running you would need to install solar panels which depending on your boat might not be an option. Typically most people run multiple batteries in parallel to run their appliances/equipment. Since you'll be running a fridge I recommend a deep cycle battery like the Bright Way Deep Cycle RV or Marine Battery - AGM - 12V - 110 Ah - Group 30H Item # BRW44FR. Deep cycle batteries are designed to provide a steady amount of current over a long period of...

  • 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.

  • Power and Peak Surge Power of Wagan Power Inverter
    The 1,000 Wat Power Inverter with Three AC Receptacles # WC3720 will absolutely be able to run your 700 watt microwave. It has a surge power of 2,500 watts and 1,000 watts of continuous power so there won't be any problems with your microwave. There will not be any issues using this with a larger 12V battery either and you can re-wire this inverter to it - I've added a link to the instruction manual for you to check out as well.

  • How To Power Small AC Household Electronics In A Van Without Using Solar Power Or A Generator
    I recommend using a power inverter like the Power Inverter 1000 Watts with Three AC Receptacles # WC3720. What this will do is allow you to use your vehicle's electricity to use household appliances like the mini fridge, the box fan, and the LED lights you referenced. Realistically, you're going to need a sizeable battery bank to power all your electronics and run them on demand. My suggestion is to calculate how much energy is used in a day. Once calculated, follow the chart linked on...

  • How Does Power Inverter 1000 Watts with Three AC Receptacles # WC3720 Attach to AC Accessories
    The Power Inverter 1000 Watts with Three AC Receptacles # WC3720 that you referenced has three standard outlets on the back of it for powering accessories like you mentioned. There's no additional wiring needed to plug in a microwave or coffee maker aside from maybe a standard extension cord if needed.

  • 1,000 Watt Inverter Recommendation for Vehicle
    We have a 1,000 watt inverter part number # WC3720 which could potentially work well for you, but it's not really designed for mounting in a vehicle dash. You may have to come up with an extension cord plus an outlet to accomplish that. I attached an install video that shows this installed in a vehicle though for you to check out.

  • Connecting Trailer Battery to Same 12 Volt Wire that Charges Breakaway Battery
    You should have no issue hooking up your trailer battery to the same 12 volt wire that charges your breakaway battery. You will just need to make sure that you do not drain the batteries when they are being used. An isolator or diode is not needed for this application. Then for a power inverter, I recommend looking at the Wagan # WC3720. This will convert 12 volt DC power to 115 volt AC power. A 3 foot DC cable is included to connect directly to the battery. I have attached the installation...

  • 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 Vent Setup to Cool Enclosed Trailer Mobile Workshop
    Even the smallest RV air conditioning units we offer will require 115-volt AC electrical service of at least 11-amps to operate properly. The Atwood Air Command Rooftop RV Air Conditioner will draw almost 4000-watts at startup and even once running it will still need close to 1300-watts to operate. Delivering this amount of power via high capacity 12V batteries and an inverter such as the 5000-watt Go Power # 34280179 will be a fairly costly and bulky proposition. Instead what I recommend...

  • Could 110 Wall Outlet be Installed in Trailer to 7-Way Trailer Wiring
    Since the 7-way has a 12 volt accessory circuit what you'd need is an inverter like the part # WC3720 ran to the 12 volt circuit of the 7-way and the ground circuit and you'd have a 110 outlet you could use in your trailer.

  • 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.

  • What Inverter / Batteries Are Recommended To Power A Full Size Refrigerator For 7-10 Hours Straight?
    The Power Inverter 1000 Watts with Three AC Receptacles # WC3720 that you mention is going to be a bit too small to power your full size 115VAC refrigerator for 7-10 hours continuously. Instead, I recommend checking out the: -Go Power Industrial Pure Sine Wave Inverter - GFCI - 2,000 Watt - 12V # 34278156. This inverter is rated for 12v battery systems, and will have more than enough power to power your full size refrigerator for 7-10 hours continuously. Additionally, for batteries...

  • Best Way To Power an Enclosed Travel Trailer
    I do have a few options for you to power a cordless drill, lights, and coffee pot inside you enclosed travel trailer but using a solar panel would not be the best or most cost effective setup. Basically, you are going to end up having to cover the entire roof of your trailer to power the above items. Instead, I recommend purchasing a 12 volt auxiliary battery like the one you would find in a car and then using a power inverter like part # WC3720 as well as a battery charger like part #...

  • Installing DC Power And Power Inverter To Cargo Trailer
    For DC electricity, I can help you out. You can run a 10 gauge wire like # 10-1-1 sold by the foot from a 6-way or 7-way connection from the 12V to a deep cycle 12V battery and then run the battery to a ground on the trailer. You can use a solenoid like # PK5231201 in your tow vehicle if you want to ensure you don't drain the vehicle battery when your truck isn't running. This will isolate the deep cycle 12V trailer battery. To charge your battery, you can use a Redarc In-Vehicle BCDC...

  • 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).

  • 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...

  • Should a Relay be Used With Wagan Power Inverter
    Though I can see why you might think you need a relay, I do not recommend using one with the Wagan Power Inverter with Three AC Receptacles # WC3720. This inverter has a simple On/Off switch; I assume you want to use a relay to conserve power from your battery but the same thing can be accomplished simply by turning the relay off. Just be sure to use the correctly rated fuse and wire gauge for the length of wire you need (which is included in the installation manual I've linked) to get...

  • Inverter Recommendation To Go From 12v DC To 110v AC
    To go from 12v DC to 110v AC I recommend the Power Inverter 1000 Watts with Three AC Receptacles # WC3720. This is a 1,000W inverter which will be more than enough to power the appliances and features 2 USB ports, as well as an internal fan to prevent overheating.

  • How to Determine Correct DC to AC Inverter Power Rating for 800-Watt Load
    It is never an ideal situation to use a device continually at its absolute maximum capacity. Since you are powering an 800-watt motor with an 800-watt inverter it is definitely being strained and that is the cause for the inverter's alarm. Ideally your inverter will have much more capacity than the connected device requires. It is definitely not a good idea to use an 800-watt inverter with an 800-watt device. All devices will draw more peak power than their continuous rating suggests. The...

  • Recommended Heating Pad to Keep Battery Warm in Freezing Weather
    I recommend using one of the Kat's Heaters pads, like part # KH22200, from the linked selection as they are specifically designed for batteries. These do plug into an AC power source though so you would need access to that kind of outlet or use an inverter like the Go Power # 34280175 or Wagan # WC3720 to convert DC power to AC power for the heater. I would be hesitant to use one of the ThermaHeat RV Dump Valve Pipe and Elbow Heating Pads, like part # 277-000161 that you referenced, on...

  • Could Wagan Power Inverter WC3720 be Powered by Honda CR-V Alternator
    1000 watts is 8.33 amps at 12 volts which would easily be supplied by the alternator of your 2018 Honda CR-V. Most alternators put out almost 10 times as much amperage than that.
