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.

  • 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.

  • Installation of Wagan Tech 1000 Watt Power Inverter on 2010 Jeep Wrangler Unlimited
    The cables included with the Wagan Tech # WC3720 are 6 gauge, and are 36 inches in length. 6 ga wire is fine for runs up to 8 feet long. For a longer wire run, say 9 to 10 feet, use 4 gauge. For runs from 11-21 feet, use 2 ga cable. The inverters are circuit protected already but Wagan recommends installing a 120 amp non-sparking (sealed) marine fuse and mounted fuse holder located within one foot of the positive battery terminal. You can find the fuse holder and fuse at any marine supply...

  • What is the Highest Wattage Power Inverter for Vehicle Use?
    The best power inverter for your 2002 Toyota Tundra is going to be the Power Inverter 1000 Watts with Three AC Receptacles item # WC3720. This inverter has a 1000 watts continuous power and 2500 watts of surge power. It will provide you with 3 AC outlets and 2 USB outlets. I have linked a review video below of one of our shop guys using an angle grinder that is powered by this inverter. You will want the Pollak Circuit Breaker - 100 Amp item # PK54871PL and a couple of ring terminals...

  • Connecting 2 Batteries in Parallel with an Inverter to Power a Freezer in Back of a 2015 Ram 1500
    Running 2 identical 12 volt batteries in parallel will produce 12 volts but double the amp hour capacity. Assuming your inverter runs off of 12 volt power then you will be good to go with this set up. Since the 2 batteries will be separate from the truck's electrical system you won't have to worry about any interference or over drawing the tow package wiring on your 2015 Ram 1500. If you do not already have an inverter I recommend # WC3720 which is rated at 1000 watts and the AC outlets...

  • 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...

  • 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...

  • 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...

  • Best Way to Power AC Fridge in Trailer When Traveling
    The best way to do what you are looking for is to use a smaller inverter like the part # WC3720 ran from a battery installed in your trailer to power the fridge. You'd want to use 10 gauge wire like part # 10-1-1 ran from the 12 volt accessory circuit of the 7-way to the trailer's positive post and you'd be set.

  • 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...

  • How to Use an AC Powered Mini Fridge in a DC Powered RV
    In order to convert the AC power your mini fridge uses to the DC power your RV runs on, I recommend the Three AC Receptacle Power Inverter part # WC3720. The power inverter is capable of handling up to 1000 watts of continuous power which should be more than enough for your mini fridge. It comes with 2 3 foot long DC cables with ring terminals already attached. The inverter has an auto reset feature built into the device in addition to cooling fans, and a low battery alarm.

  • What Deep Cycle Battery is Needed to Run 450 Watt Appliances for 7 Hours with Inverter # WC3720
    You will need a deep cycle battery with a capacity of at least 315 amp hours to run 450 watts of power for 7 hours. If you check on page 7 of the linked instructions for the Power Inverter 1000 Watts with Three AC Receptacles # WC3720 it states to divide the amount of watts you are using by 10 (450/10 = 45) and then multiply that by the amount of hours you need them to last (7) which then gives you the amount of amp hours your battery needs to be (45 x 7 = 315). As noted in the instructions...

  • 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.

  • 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...

  • 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.

  • 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.

  • 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 Power a Fridge and Furnace in a 5th Wheel Camper
    I do have an option for you but the 12 volt power circuit on a vehicle's 7-way trailer connector is mainly used to charge a breakaway battery or provide a small trickle charge to an auxiliary battery. It will not be nearly sufficient enough to power a furnace or small fridge in your camper. Instead, I recommend installing an auxiliary battery on your trailer and then using a battery charger to keep it charged like the Redarc In-Vehicle BCDC Battery Charger # 331-BCDC1225D which actually...

  • Recommended Power Inverter and LED Trailer Lighting for Enclosed Trailer with Deep Cycle Battery
    One thing to note first is that the vehicle's 7-way +12V power circuit being key-controlled can be changed to provide power at the trailer connector at all times. Some vehicles keep their +12V hot at all times while others are key controlled. You can easily make yours an always-on setup by re-routing the wire for the 12V power circuit directly to the battery, connecting it through a 40-amp breaker like # PK54540. You can also just replace that complete connection using 10-gauge wire # 10-1-1...

  • 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...

  • 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...

    A deep cycle battery can be used in this scenario with no problems as long as it is wired properly. A deep cycle battery is capable of longer run times, more amp hours = better battery, and more charging cycles for deep discharges. I recommend using a Group 24, 28, or 32 Deep Cycle battery. Wiring your truck battery to a secondary 12v Deep Cycle battery through the Battery Isolation Solenoid # PK5231201, will prevent the cab over camper from drawing power from your truck battery when it...
