Jeff Flowers on June 27, 2014 95 Comments A power inverter converts 12 volt DC power to standard household 110-120 volt AC power, which allows you to run AC electrical equipment off your car or marine battery for mobile applications, emergencies or simple convenience. Choosing the Right Inverter Size Power inverters come in many sizes, measured in watts. The amount of wattage you will require depends on the total draw of the devices you’d like to use. Many home appliances and power tools have their wattage rating indicated on the product itself. Wattage rating can also be calculated by using this formula: Volts (120) x Amps = Watts To determine if several appliances can be operated at the same time, simply add up their wattage ratings to see if the total falls within the specifications of the power inverter. For example, if you have a two-outlet inverter and will be plugging in 2 devices at once, add up the total wattage of both devices, then add at least 50% more to account for peaks or spikes in the power draw. For example if your DVD player draws 100 watts and your laptop another 100 watts, a minimum 300-watt inverter is recommended. If the item is motor driven, it requires additional start-up (surge) wattage (typically 2-3 times the continuous wattage required) to start the device. For example, a miter saw that runs at 700 watts might require 1400 watts to start up. If your inverter only supplies 1000 watts, you will not be able to start it up. In this case, you would want to select an inverter rated at least 1400 surge watts to handle start-up needs. The estimated watts for the appliances below are estimates; please check your manual or the appliance itself for the actual wattage required. Doing this will ensure you select the correct inverter the first time. Appliance Est.

They might also come with jumper-like cables for connecting directly to a battery. Larger units are often hardwired into vehicles, RVs or boats. Inverters normally have one or more standard outlets to power laptops, small-screen TVs, video game players or portable DVD players and other devices. A DC to AC power inverter is great for camping at parks that do not provide electricity. The toaster, blender, and boom box can all still be used. On your boat, you can plug in devices like a digital movie camera to take videos after the camera’s battery runs low, or brew up a pot on-board with your coffeemaker. Power Inverter or Generator? Whether to use an inverter or a generator depends on the type of load and how often you will need emergency AC power. Generally, an inverter is more economical power alternative to run items under 1000 watts, suitable for small appliances, TVs, VCRs, DVD players and other low load devices. If you plan to operate a refrigerator, freezer, washer, dryer or well system, then a generator is a better choice. If your planned power consumption exceeds 2000 watts, you should choose a generator, as the draw in the battery will rapidly deplete its power. True Sine Wave or Modified Sine Wave? Power inverters produce one of two different types of wave output: Modified Sine Wave True Sine Wave Modified sine wave inverters deliver power that is consistent and efficient enough to run most devices adequately. These types of inverters are the most popular and affordable. They are also small and highly efficient. The Vector power inverter line is based on modified sine wave technology. True sine wave inverters are the most expensive, but they also deliver the most consistent, highest quality wave output. Some sensitive equipment requires a true sine wave, like laptop computers, tool battery chargers, professional audio/video equipment, certain medical devices and variable speed tools. If you aren’t sure if the device you want to use requires a true sine wave or not, call the manufacturer to ask. Any AC device will run on a true sine wave inverter, whether it requires it or not. Battery Basics photo credit Batteries should be in good condition. Old or weak batteries should be replaced before connecting them to an inverter. Automotive batteries are not suited to repeated long discharge and recharge cycles. They will have to be replaced more often than a deep cycle battery. Deep cycle batteries are a better choice as a power source for an inverter. They are designed to be repeatedly drained and recharged. It is also a good idea to have more than one battery supplying power to an inverter. The amp hour rating of a battery is the most important measure when choosing a battery for power inverter use. This indicates how many amps a battery can deliver for a specified period (usually 20 hours), showing how long it will run before needing to be connected to a battery charger. To prolong battery life, you should not use more than 50% of the battery’s rated capacity before recharging. Reserve capacity indicates how many minutes a battery can deliver a certain amount of current (25 amps for most batteries) at 60-75° F. Batteries will discharge much quicker at lower temperatures. Safety Tips Always use a power inverter that is rated high enough for the device(s) you are running and avoid adapters that would allow more outlets than the unit is designed to accommodate. When using your power inverter continuously inside a vehicle that is not running, the engine should be started at least once an hour for 10-15 minutes to keep the battery from discharging. Do not start a vehicle in a closed garage, as the carbon monoxide in the exhaust is fatal. Power inverters work best with a battery that is in good condition and fully charged. A weak battery will be drained easily if demands are too high. This could leave you stranded so be sure to check the battery’s condition before using a power inverter in a stationary vehicle. If the power inverter is being used while the vehicle is running as in the case of a road trip, there should be no problem with the extra draw, assuming the battery and alternator are in good condition. Make sure your vehicle’s wiring harness can handle the current before plugging in an inverter to your cigarette lighter. You may need to hardwire the inverter directly to the battery to safely use it. Make sure the inverter is properly ventilated. Even a small inverter generates heat. Check to see if there is an internal fan with any inverter over 100 Watts. Place the inverter in a well-ventilated area when in use. Check the owner’s manual for the proper wire size for battery cables when connecting the inverter to the battery. Most manufacturers recommend 4 to 10 feet of cable length, depending on the inverter. Avoid aluminum wire because it has higher resistance to current flow than copper wire. Working with car batteries can be dangerous and can result in serious injury, and improper use of a power inverter can lead to electrocution or battery failure, so for your own safety be sure to read and follow any and all safety precautions that are listed in your power inverter owner’s manual.

Hal says August 27, 2018 at 5:50 pm Good question, what is minimum inverter needed to keep the food from spoiling in time of an emergency? modified sign wave or pure sign wave etc. will a 600 watt inverter do it? thanks Reply
thegoodtom1 says November 1, 2018 at 5:53 am your appliance should have a label that shows the running(not start up surge) watts. start up is usually 2x the running watts for a refrigerator or a/c. Remember that leaving the door closed will extend the cooling time and doing so will allow intermittent inverter use just to regain the temp. within which will save your batteries. Reply
Jon says May 13, 2019 at 2:43 am You want a pure sine wave when using inverters to power motors and compressors. As modified sine wave will generate excess heat and damage your appliances. Reply

chris says June 7, 2015 at 11:35 am I have a 300 watt amp, can I run it through cigarette lighter? Reply
KB5ZCS says September 25, 2017 at 1:51 pm yes you can,the cigarette lighter plug will handle up to a 400 watt inverter……. Reply
Doug says January 17, 2018 at 12:20 am Wattage is volts X Amps. A 120 volt inverter needs 2.5 amps to make 300 watts. Power stays the same no matter how you convert it. ( With probably a loss for heat because nothing is 100% effective in converting power) To get 300 watts of 120 volt AC power out, you would need to draw 25 amps of 12 volt DC from the cigarette lighter! ( both equal 300 watts) Does your cigarette lighter have a 25 amp fuse and 10 gauge wire? Reply
Jered price says May 14, 2019 at 4:41 am No Do not run a 300 watt amp on a cig lighter youll fry the wires ,if u up the main fuse and catch. U will catch car on fire Reply

Charlemagne Parato says June 19, 2015 at 12:53 am what is the POWER DRAW from a battery while it is running? it that variable based on power going out of it? Reply
Gary says September 13, 2016 at 5:09 am Need to check with tech support from the inverter’s manufacturer. Expensive inverters are 90% efficient and decent ones are 70% so, whatever your output power is, you could have to draw the same amount of power from your battery plus 10 to 30% more. Confusing the issue is that inductive loads like coils and motors have to work in their rated ‘power factor’ whereby they draw slightly more than the given current draw. If you already have an inverter then you just need to put it through it’s test and see how long it lasts under your load. Reply

paul says October 1, 2015 at 9:39 am Does this mean i can run a bigger inverter and not drain my battery as long as the engine is running? Reply
Gary says September 13, 2016 at 5:14 am You got the same problem that guys with high-power sound systems or mechanic’s trucks have, in that you need to match the capability of your alternator’s output amps with the current you intend to draw for the vehicle plus the accessories going at the same time. Some opt for dual batteries – one for the vehicle and one for the accessories just so that when things get crazy, you only kill your accessories battery and not the one to get you home. They make a special charger that charges both but the draw is isolated to only what is connected to each battery’s circuit. Reply
Jose Baez says October 20, 2015 at 8:30 am I have a wet vac that is 3.0 peek I tried a 750 inverter n it kept shutting off will a 1000 be good or do I need like a 1500.

KB5ZCS says September 25, 2017 at 1:53 pm Go with the 1500 watt or bigger,but an 1500 watt should work…… Reply
Carl Harmon says April 28, 2019 at 8:52 pm Go with the biggest one you can so you not limited we had a mobile detail we used two shop backs at a time and an air compresser at same time we had a 3000 wat peak 2500 watt inverter if I’m not mistaken I know it was 3000 watt peak we didn’t have any trouble we did have to add another battery total of 3 battery’s but that was just for precautions Reply
Bud says October 20, 2015 at 7:26 pm Hi, I bought a Xantrex 700 W inverter. Is it safe to plug into a car’s cigarette lighter socket for just running a printer while on the road? I know for bigger consumption the lighter will not do. Reply
Blake says December 14, 2015 at 9:59 am The wattage thru a car cig lighter/outlet is limited by the outlet’s amp fuse rating. So most car power outlets are limited to 120 watts (12 V x 10 amps) or 180 watts (12 v x 15 amps) based on most car power outlets having a 10 or 15 amp fuse. Reply
KB5ZCS says September 25, 2017 at 1:58 pm No dont do that the 750 watt inverter will pull to much power for the cig lighter plug dont do it are you will blow an fuse of worse burn or melt your wire’s in your car,you can connect it direct to your car Battery only and with the engine on while using the 750 watt inverter…….

Chopper says May 31, 2016 at 10:19 pm If you haven’t seen this by now… your 115 is not much a difference as here in the U.S., the volts are usually rated from 110v to 120v. You’re right in the middle. Please do also let me know if you’ve found anything to the contrary. You can’t ever have too much info. when you’re shelling out bucks to keep the power going when the power company can’t. Reply

Douglas North says April 17, 2016 at 12:18 am I have a 80lt freezer on the lable 90w input 1.2amp currant, we bought a 1500w inverter but when i turn it on the inverter was paulsating, why ?, but when I put my drill into it, it worked ok. On the paper witch come with the inverter the example is 220x volts,6.8= amps, and 1500w . Con you help. Doug North ps shoud the inverter do the job. Reply
Chopper says May 31, 2016 at 10:16 pm Your start up on your freezer is probably more in peak than your 1500 will carry. Your inverter buy should be based on your peak start up appliances you’re going to run. You should go to a 2500w continuous/5000w start up/peak if you’re going to run major appliances with it. Your source of power (battery) has to be big enough in Ah to handle your load also. Anyway, a buddy taught me to go big in this area. He recommended to me that you buy something big enough that you won’t go near the peak taxing of the inverter. This keeps the insides of the inverter from going bad. Don’t forget the battery bank. It MUST be big enough to supply the demand. Reply
Gary says September 13, 2016 at 5:28 am Refrigerators and freezers have a run-current rating, but they also have a start-current rating. The start winding is engaged to overcome the resistance of the motor to start up under an already present load, then disengaged after a set amount of time. Could be battery capacity, could be battery connections (low voltage, very high current draw), could be the waveform of the inverter, or it’s capacity to handle inductive loads. Reply
Chris says June 14, 2016 at 6:45 pm Which cable hooks up first positive or negative to a deep cycle battery? Reply
Gary says September 13, 2016 at 5:40 am A deep cycle battery is just an expensive battery which won’t prematurely die if you run the voltage down to it’s minimum a lot of the time, and require a lot of current draw, and recharging to bring it back up to full charge, and usually can sit with a trickle charge always going. Past that, look at your grounding system. Is it the negative lead that goes to grounding framework or the positive? It tends to be safer to attach the polarity of the battery that goes to the grounding framework, last. Reason is, that if there is no ground, if you drop the ungrounded lead accidentally or touch ground with your ratchet while you’re attaching the battery terminal on the ungrounded lead, then there’s nothing to short-circuit to, because it hasn’t been attached yet. The other way, once you have battery on the framework ground, you’re always wary of how much you’re turning your ratchet to make sure the handle doesn’t accidently touch the frame as you attach the hot lead.

I’m running 2 batteries in parallel getting charged by 4 solar panels (apx. 110x30cm). As soon as I plug the heater in the voltage is lower than 12 and teh inverter startes peeping. One of the batteries is brand new the other one 2 years old. The 2nd reached only 75% when we tried to charge it at lordco. Suggestions? Reply
Shawn says December 15, 2016 at 12:39 am batteries must match so there is no draw on each other so the best thing to do is have 2 identical batteries and same condition both new or both used of course new is best Reply
J says December 15, 2016 at 5:09 pm Depends on several things, including how long you want to run the heater (400W X # hr) and watt-hr capacity of batteries. If you expect the solar panels to power it, they have to contribute enough power (volts X amps X inverter efficiency) to give 400 watts, or else you will discharge the batteries (but you can recharge with the solar panels later). If your batteries are big enough, you may be losing some energy in connecting cables that are too small a gauge, or weak connections. (sorry no conclusive answer) Reply

Chris says May 17, 2017 at 10:15 am I’m using a 400 x 800 watts Cobra power inverter that I purchased on ebay for $25. It runs 2 laptops and a battery charger. This is coupled with 2 35 amp batteries (70 amps) and 6 100 watts solar panels. I know I’m solar panels high, but I expect to upgrade the power inverter to at least 1000 watts or 2000 watts continuous (if I use a compact freezer) and 100 watt agm for fan cooling operations. This is a temporary setup for summer weather as it can get close to 100 degrees for many days. I have 2 emergency batteries for laptops batteries 35 ah AGM and 2 6V Golf Cart Batteries. I will use the Golf Cart Batteries as a last result, as they are the heaviest to move around and they not as reliable. But there storage capacity is enormous at 225 ah.

Jennifer says March 17, 2018 at 11:31 am My son lives in Liberia Africa where they use outlets that look just like ours in our USA home, however there’s are supplying 220 instead of 110. Does he need an inverter or is a simple adaptor fine? if he uses an adaptor what does it need to be? Reply
John Cowhig says March 14, 2019 at 12:28 pm It sounds like Liberia has the same current as Germany. The 220 Volts is Alternating Current , The same type of current we have in America , but in America our voltage is 110 Volts. An inverter will not work because inverters change Direct Current ( DC) into Alternating Current ( AC) A simple adaptor will NOT work because while the type of current ( Alternating Current , or AC ) the voltage is NOT the same. Do not do this , it is dangerous. I think what you need is a step down transformer that changes 220 V AC into 110 V AC. Reply

I need to plug in the Wet Vac and to run about 1/2 hour to wet vac water up in my Condo after a hurricane. What size Power Inverter should I buy? Do you recommend any Brand? Thanks! Reply

Matthew says June 23, 2018 at 3:28 am I have a 1000 watt( 2000 watt peak) Jupiter converter. With a 12v deep cycle battery. I cannot get my 12v electric pressure washer to stay on. Do I need a bigger converter? Reply
karina says August 19, 2018 at 9:21 am I’ve got a 2000w invertor and three deep cycle batteries in my caravan. I’m not sure if the batteries are running at the same time however. I want to use a small blow heater for my caravan. Should I buy a 350w 240v heater and use the invertor. I’m guessing it should work. Or will it be more efficient to just buy a 12v heater of the same watt? Reply

Sam B says September 11, 2020 at 11:31 pm My in-law are in the Philippines 220v and I sent them a few appliances , my question is ….the most power hungry item was a kitchen ninja120v with digital touch screen, @1250w , I just bought a converter to send which takes the 220v and converts it to 110v @2000va Will this be enough to run the ninja? The kitchen aid mixer is only 350w so I’m not worried there Reply
