Is there a car AC adaptor for PS3?
I am going on a 14 hour road trip and I need something to do in the car besides sleep. I have an iPod Touch but that won't last for ever. I was wondering if I could bring my PS3 because our car has power jack things but I tried googling PS3 AC adaptor and couldn't find anything. If there is a cord that you can plug into the PS3 and also into the car please let me know! Thanks!
If I plug a 12V AC adapter into a DC appliance, will it work?
No Jonathan it will not. You would need to rectify with diodes to do that. Some devices need a good regulated, strict control of available current and a fixed steady voltage and no ripple so be careful. Best get an adapter that is made for it.
Dangers of plugging a 5v device into a 9v adapter?
You're right -- there's no problem in going over the amperage limit. In fact, you should. The device will draw as much current as it needs, and it's best to have a comfortable cushion. Same thing as your household electrical outlets. They're rated at 15 amps, but you can use a radio that draws maybe 100 milliamps. I wouldn't use a 9-volt adapter for a 5-volt appliance. Even though most low-voltage electronics stuff has a very wide tolerance, nearlyh doubling the voltage would be a big risk. There are some fairly simple electronic circuits that you could wire together to drop the voltage, but that's unnecessary. The easiest solution would be to go to your local Radio Shack store and buy an adapter for the plug. It will have US flat prongs for the wall adapter and the two round plugs from your VGA/HDMI adapter fit in the other end. (If your plug is some other shape, you can probably find others as well.) These things are widely available online as well. Radio Shack charges $7 for them. That's a rip-off, but if you buy online you'll get hit with shipping charges that are three times the value of the thing anyway.
If a device works with 12 volts and 50 to 200 mA, Can I plug a 12V 500mA adapter to it?
The true answer depends on-What is the actual device.What are the make and specs of the adapter.If your device is anything else but a battery, which consumes 200mA at 12V then try measuring the voltage across adapter terminals / device terminals after connecting the device to the adapter. If the voltmeter shows 14V (or anything higher than 12V), remove the adapter. If it’s at 12V, it should not harm the circuit.This is mainly because-If your adapter is 12V, 500mA, transformer based power supply (big, heavy in weight - around 0.5kg, not used generally these days) then it’ll draw only 50~200mA current from source (Source & Load Power will match).If your adapter is 12V, 500mA, SMPS based (small and lighter in size & weight) and is made from a standard company it’ll do.It’ll try to draw 500mA current from source but will limit the output voltage at 12V - limiting the current to match load current (Source & Load Power will match).If your adapter is 12V, 500mA, SMPS based lightening / boost / fast charger it’ll harm the device (Even if it’s made by a standard company)!If your adapter is 12V, 500mA, SMPS based (small and lighter in size & weight) and is made from a non-standard company (a cheap adapater, that is) it’ll harm the device!It’ll try to draw 500mA current from source and will NOT saturate at 12V, instead will increase the voltage to force 500mA current into the device (Source & load power will not match).So, basically the device will receive >12V and this will do the harm.If your device is a battery, doing this will damage the battery.
Does it wear my car battery to leave a USB charging adaptor in the cigarette lighter all the time?
There are a number of options.If the power to the cigarette plug socket is switched off when the engine is off, then there is obviously no risk.If the power to the cigarette plug socket is not switched off, then there could be risk. Assuming that you aren’t actually powering anything from the adaptor, there will still be a tiny bit of power consumption. There is often an LED in these adaptors and the buck converter will also draw some standby current.The current draw is likely around 15mA-20mA. Assuming a worst-case scenario of a small capacity battery (40Ah), that is worn, and that shouldn’t be drained to less than 50% of its capacity, it will still take about 20 days, and this is a worst-case scenario.It is thus extremely unlikely to cause significant battery drain or wear if you drive somewhat regularly. Everything causes wear, but the wear will be negligible. Starting your car, which requires a very high current, will cause much, much more wear than a tiny cigarette lighter adaptor drawing very little current.
How do I charge a car battery with a 12V DC adapter from a 120V outlet?
I need to recharge a 12V car battery that I use use to power a 12-volt appliance. I do NOT want to put it in my car or use my car's alternator to charge it in any way. Instead, I have a 12V DC power adapter that was previously used to power a different 12 volt appliance. I want to expose the leads on the adapter and connect them to the battery terminals to supply a charge. How can I be sure I have connected the wires to the correct terminals? I don't want to invest in a special car charger for 120V outlets, nor do I care if this will shorten the life of my battery. The battery was free and I just want to get some extra life out of it.
Could an adapter with an output voltage of 12v start a car with a dead battery?
I am not an expert here so please excuse any errors.But when you say the word adapter instead of starter cables, It sounds like you are not talking about jump starting the car.Please do not try doing this anywhere!Generally, even though a car uses a 12V DC battery. During cranking with the starter motor- the Voltage value is not the critical number, it's the Juice as is a function of voltage and current. So the current value required at that instant is really high.If you are talking about using an adapter to connect an AC socket to a DC starter motor of your car, you are talking of disaster. Because an AC socket in your building depending on your country has a fixed range of voltage and current. While your adapter does step up or step down the voltage values accordingly, the current values may not be changed.Secondly, that adapter may not be designed to process such high value of current at an instant, like when you start your car. I am not aware of these products being sold in the market. I would not suggest trying this method.You can either use the adapter to charge you battery out of the car placed in a safe ventilated environment and then start your vehicle with the battery once its charged.Or you may crank the engine by engaging the 2nd gear and have your friends push the vehicle to use “Push start” (Not to be confused with ignition button start or start-stop system)Jump starting your car would be another option.Follow safety rules and do not mess with high power electric sockets. Such acts are even punishable by law in some countries.
Can I plug a vacuum cleaner into my car?
First of all there are 12V systems and there are AC inverters with plugs that furnish 120 or 230VAC.You are not telling me which type of plug your car has.YOu are also not telling me what kind of vacuum you have, whether its one of those 12V car vacuums with small capacity and low suction but designed for cars, or if you want to use your home of shop AC powered vac.I’ll tell you this. If you car has a 12V outlet and you have a car vac with a 12V plug that fits the outlet it is probably safe to use.Home and shop vacs powered by AC usually use a lot of power. Cars with AC outlets are generally for powering small electrics items with low amperage draw. Don’t try and plug a home or shop vac to them. You’ll probably damage it.If you want to clean your car drag an extension cord to the car or take it to a DIY carwash, they usually have coin operated vacs for hire.

Plug in electric skillet to car power inverter ?
We (family of 5) are trying to save money when we travel this year, wondering how it would work to use a power inverter in our Jeep - then plug in some small cooking appliances like electric skillet and coffee maker to make our meals at rest stops. Didn't know how much it would drain our battery or if it would even work. Anyone have experience with this ?
