to ac power inverters Frequently Asked Questions
will a dc to ac power inverter damage a laptop computer?
Have a Toshiba laptop and am going on a long trip. I wish to use it while traveling. Is an inverter the way to go?
yes, the inverter is the way to go and won't hurt your laptop, and you can charge your other stuff with it too
Can I use a Portable "Home" AC in Van ?
The built-in AC in our GMC van bit the dust and is FAR too expensive to have fixed.
If I buy a small "portable" home air conditioner, and run it through a Power Inverter, is there any reason I cannot plug it into the cigarette lighter and place it behind the seats to air condition our van? The total cost from eBay for everything will be under $200.oo.
Also, is there any "danger" if I do NOT vent the warm air out of a window, but just let it circulate inside the vehicle?
Thanks.
The main problem with the built-in AC is that it is leaking freon several places. The independent repair place wants over $1,500.oo to repair it, and the dealer wants even more. They can just forget THAT.
You should let the warm air exit the car, then close the window so your circulating air is cold. I hope the two articles below give you important and informative advice. Please read the warnings of proper use and proper inverter for specific devices. As article one says, the hardest device to run on an inverter is an air conditioner.
article #1: Power Inverters and Air conditioners
The air conditioner is one of the hardest household appliances to run off of an inverter. The first thing to do when getting ready to run an air conditioner on an inverter is to get all of the specifications for the AC unit. The most important spec that you will need is the LRA rating. What this stands for is locked rotor amps. The LRA rating is what the AC unit will draw from the inverter while the compressor starts up. This is a very important spec when sizing an inverter for use with an AC unit. After you get this spec you will multiply it by the voltage and this will be the startup wattage needed by the inverter.
For example if your LRA is 60.6 amps if you multiply this by 115 you will get roughly 7000 watts at start-up.
The next thing to take into consideration for a AC unit is battery bank size. The best batteries that we have found that work well with inverters are the 6 volt golf cart or solar batteries. These are more cost effective and on average have higher amp hour ratings then the traditional group 27 12 volt deep cycle batteries. The 6 volt batteries will be connected in series. This will double the voltage to 12 and keep the amp hour rating the same. The inverter will see this as one big 12 volt battery. Your average 6 volt battery is 220 amp hour and sells for approx. 65.00. and your average deep cycle 12 volt battery group 27 is 115 amp hour and sells for 130.00. So if you get two of the 6 volt batteries it is twice the size at 12 volt s and you pay just about the same amount . If you want any kind of run time with a air conditioner it will require a large battery bank. I would have to say a minimum of 4 6 volt batteries wired in series to get longer then an hour.
Your next step in setting up a system for use with an AC unit is finding a sufficient recharge source for the batteries. You will want to have a minimum of a 150 amp alternator to recharge a system with a small AC.
article #2: 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.
A power inverter converts DC power or direct current to standard AC power or alternating current, which allows you to run electrical equipment off your car or marine battery for mobile applications, emergencies or simple convenience.
Power inverters are small rectangular devices that have a trailing wire with a jack that plugs directly into the cigarette lighter on the dashboard. They might also come with jumper-like cables for connecting directly to a battery. The device normally has one or two outlets for standard electrical cords. Your laptop, small-screen television, video game player or portable DVD theater are all examples of devices that will get you through a long ride, assuming you're not the one driving!
Power inverters are 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 the digital movie camera to capture those great water-skiing videos you might have missed after the camera's battery ran low!
In a utility outage a power inverter can be used for emergency electricity. Just run an extension cord from your car into the house, or if you have a charged spare battery you can connect the power inverter directly. Plug in a radio to tune into important alerts, run essential medical equipment, lights, or whatever else you need that falls within the inverter's power limits.
Power inverters come in many models that vary in watts. The amount of wattage you will require on yours depends on the total draw of the devices you'd like to use. 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 theater draws 100 watts and your laptop another 100 watts, a minimum 300-watt inverter is recommended.
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. Power inverters operate on the assumption that the battery is in good condition and fully charged. A weak battery will be drained easily if demands are too high. This could leave you stranded.
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 providing the battery is in good condition.
