Video Transcript for Wagan 1000 Watt Power Inverter Review

Speaker 1: Today we're gt be taking a look at the Wagan Tech Power Inverter 1,000 Watts with 3 AC Receptacles, part number WC3720. This heavy-duty inverter can give you 1,000 watts of continuous power. That's enough to run most household appliances, and also great for road trips, on the job site quick applications, and for convenience in emergency situations while camping.When comparing this to other power inverters on our website, this one's going to be the most heavy-duty. 1,000 watts far exceeds the capacity of other inverters. This one does require a little bit more install, as you have to hook it up to the battery directly, and if you want to store it inside the vehicle it can be more difficult to run the wires from your inside to the outside. The other inverters typically plug in through your power outlet, so they're just plug and play.

If you need that extra juice, this is the way to go.It has three power receptacles, two USB ports, and an on/off switch. It comes with one 3 foot power cable and one 3 foot crown cable. There's ring eyelets at each end of the cable that can be connected to your battery and the other end securely connected to your inverter. Its small, portable design will allow you to take it out of your truck when you need it. Just connect the positive cable to the positive on your battery.

This could be noted by red coloring and a plus symbol. Connect your negative to the negative cable on your battery, and this can be noted by a black cable and the minus symbol. Then connect the black to the negative on your inverter and the red to the positive on your inverter.Let's take a look and see what this thing can do. We can power our grinder here, and plenty of other tools. With 1,000 watts at 120 volts, that's roughly 8.3 amps.

It has built in safety features such as auto-reset, short circuit protection, overload protection, low battery alarm and shut down, and a cooling fan. The two USB ports put out 5 volts and share a 3 amp output.Here we've got our Redarc mounted inside of our vehicle. This is ideal for long road trips. This way, you got kids in the back, they can plug in their Xbox, laptops. It's also great for business trips.

Here we've got our laptop plugged in, and it's powered directly off of our inverter here. If you need to use your laptop or you need to charge it up on a long road trip, this is perfect for those traveling businessmen; you're ready to go at any time. Never miss a meeting, Skype conference, or email with this system.When you're done with work, plug in your Xbox and have some fun. Whether you're out on a road trip, taking a break at a rest stop, you have two jobs and you're taking a break between jobs chilling your truck, on the slopes but you're taking a moment to warm up, so you can stop and have some fun, stream some movies from your gaming system, pop in your favorite game, hang out with friends anywhere, anytime. With these three outlets you can use multiple devices and push your vehicle's utility to the limits.Now, you are going to need some additional wire to run this up from the battery from here. You can get some additional wire at etrailer.com with part number BBW20026. This will have enough wire to run from the battery back to your Redarc in any position, and will also be ideal if mounting it inside of your RV, because it's a 24 foot length of wire, 3 gauge thickness so it can handle the amperage drawn 00:03:16. Now, if running your own wire, you're likely going to need some new eyelets to connect it to your battery and to your inverter. You can pick some of these up at etrailer.com with part number SWC57048.Now, if you're mounting your inverter inside your vehicle permanently, it is a good idea to have your cable hooked to a circuit breaker or fuse just in case of emergencies, if there's a collision or the wire would short out, it wouldn't cause and welding to the vehicle or potentially a fire hazard. The circuit breaker we're using here on our project is part number PK54871PL, and this is rated for 100 amps so it'll be able to provide plenty of juice back to our 1,000 watt inverter. When hooking up the circuit breaker for your inverter, you're going to want to put the battery positive to your inverter on one side of the circuit breaker, and then a cable from the circuit breaker to the battery on the other side. This will ensure that you're properly protected. That completes our look at the Wagan Tech Power Inverter 1,000 Watts with 3 AC Receptacles.

  • 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...

  • 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 # AT15025-21 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...

    You can absolutely connect the Power Inverter 1000 Watts with Three AC Receptacles # WC3720 as a way to run your Furrion Refrigerator for RVs # FCR17ADA-BL while you are traveling. To do so you would use a battery box like you mentioned, the NOCO Snap-Top Battery Box with Strap for Group 24 to Group 31 Batteries - Vented # 329-HM318BKS, but you would also need a charger for that battery. The charger will take power from your tow vehicle's battery and charge the auxiliary battery which is...

  • 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. Then the Pure Sine Wave inverter, the Wagan Elite 200 Watt PRO Pure...

  • 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.

  • Inverter Recommendation for Powering Outdoor Refrigerator
    What you are asking about is very possible, but you'll want to consider how much amperage the fridge draws to see if your charging system/battery will handle the load. Going with heavier gauge wire is definitely recommended. Especially since you mentioned it's a distance of 20 feet. How heavy does depend on the amperage draw of the fridge as well. The Wagan inverter part # WC3720 would be a great choice for this as it can put out up to 1,000 watts of continuous power. One of it's intended...

    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...

  • 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).

  • 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.

  • 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...

  • 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...

  • 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).

  • How Long Will AC Power Inverter Run Off 12 Volt Battery
    A 1500 watt AC Power Inverter will run for approximately 16 hours based on the 200 amp hour rating of your 12 volt battery. 1500 watts of AC power at 120 volts is converted to 150 watts of DC power at 12 volts. Amps = watts รท volts, so 150 watts divided by 12 volts equals 12.5 amps. We then divide the 200 (amp hours) by the 12.5 amps to get the 16 hours. We don't carry any 1500 watt AC Power Inverters, but the # WC3720 1000 Watt AC Power Inverter powered off the same 12 volt battery...

  • 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...

  • How Does Power Inverter Attach to Trailer that Uses Solar Panels with Converter
    So all of your charging and power circuits run to your trailer battery so all you need to do to install an inverter on it like the Wagan part # WC7320 is run the power and ground wire of it to the battery and you're set. Since you already have a converter on the solar panel charge line for the battery that won't be an issue again either. This would be a large enough wattage inverter for the setup you have as well.

  • Power Inverter to Run Fan or Heater in Stock Trailer
    You may be able to use an inverter, depending on the type of battery on your stock trailer. If it is a charged 12V vehicle battery, then yes, you would be able to use an inverter such as the Power Inverter # WC3720. Apart from that, you would be able to use a generator such as the Goal Zero Yeti 150 Solar Generator # 287-42060 which is safe for indoor use and has an AC inverter so you can plug in a fan or heater for your children.

  • 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...

    In order to determine the length of time that an automotive battery will last when using an inverter pulling 1,500 watts of power, you will need to know the amp hours of the battery that you plan to use. For that much wattage though I can't imagine very long if it's a standard battery. Since 12 watts = 12 volts that means that you'd need a 125 amp hour rated battery to power the blender for one hour. 1,500/12 = 125

    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...

  • 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.
