- Q: can we use welding cable to hook up amp in our car?rated 200amp
- Yes many people use welding cable as long as its sufficient size, its usually the exact same thing as car audio power wire. 200 amps for how long? The longer the run of wire, the thicker you need. What gauge is it?
- Q: I just bought a Sandisk MP3 player e200 series. It come with a USB connector which according to the product manual, its also used for power charging.Unfortunatly, it doesn't work with my laptop. I've tried to used the USB cable to charge but no power transmit to the mp3 at all. I guess my USP port in my laptop has too low capacity.I would like to buy a separate power cable for my MP3 but I am not sure if it is available. I can not find information in the Sandisk website either.Anyone knows that is there a seperate cable power for this model and where can I buy it?
- No it charges through the USB cable. You can use a powered USB hub or buy a USB wall plug to charge it.
- Q: Hi, Im building a computer and my Power supply dosent have enough Cables/wires for all the slots. We do have enough to fill one motherboard power slot and we also have enough to fill about a hal of one. Can my computer run with just half of one of the slots? Also, my computer's Graphics card, a Gigabyte GV-N560UD-1GI nVidia GeForce 560 Ti, has two power slots, and the wires that it comes with have 2 4 pin peripheral power cables brnching off of it. My power supply only has enough to fill 1 of the cables. My dad says it will be fine but i dunno. Please awnser quickly! Any awnsers will be much a preiciated
- I'm sorry but no you need to have all the correct plugs installed if you expect them to run correctly. You didn't really give any info about the power supply but for that graphics card you generally want between 550-600 watt power supply to run anyways. Sounds like you will either need the proper adapters or another power supply altogether.
- Q: So I have this monitor that only has ONE port on it, which is a USB cable slot. Typically you would connect it to a laptop, and the USB cord also supplies it power at the same time display connection.
- I have not seen or read from any source that RCA cable can be used for power. It is designed for audio connection and video connection only. The wire are not designed for use with electrical power connection, it will over heat and the wires will melt. Hope this will help you out.
- Q: I have a hp laptop from south asia. The adapter connects with the laptop and the power cable. The power cable has a 3 round pin plug which says 6A 240V~. On the hp adapter for the input it says: 100-240V~ 1.6A 5-60Hz. It also says Connect Only to Grounded outlets.Now I am in canada. All i know is that here they have 120 V in normal power plugs. Also they have 1 round and 2 rectangular pins to plug in the outlet.I bought this adapter which basically connects the 3 round pin plug into the adapter and the adapter has 3 canadian pins. The thing is that it says 250V 10A on the adapter. So I am not sure if it will hurt my laptop if I use it. I am a bit confused because Canada has 120V and the adapter accepts 250V. The HP adapter has a range from 100-240V. Will this be ok to use since the HP adapter will just convert the 120V into the proper output for the laptop or do I need one the expensice Voltage converters for the laptop?
- It will work fine on 120 or 250 volts, the grounded outlet is for your safety, most places in Asia are doing away with the round plugs ok.....
- Q: What is the parallel use of the power cable
- Do not know what you want to ask? What about your situation? Normal or pregnant? Normal this radiation does not affect what, if it is pregnant, this is far away from the best. Pregnancy is most needed to stay away from the microwave!
- Q: its like a big power box the has two metal prongs, and is about 2quot;X3big and fits into the same size slot, if you push it in it gets power for a second then doesnt if you jiggle it around it gets power for a second and doenst.anyone know please?
- you need a very new cable it is corrupted
- Q: When I plug in my xbox that wire with the box on it has a red light instead of a green and ocassionally it turns yellow and my xbox wont turn on how do I fix this
- I'd suggest trying a different outlet. Yellow isnfine cuz when mine is off its yellow. It should be green when you turn it on. If it's still red I'd say give xbox a call or get a new cable. Xbox helps but not that much but u can try
- Q: im running 4 ga power cable through my 2003 civic and im wondering if anyone hase any good places to run it through?
- yes okorder /
- Q: Sometimes I have to jiggle the chord or plug it in the right position to get the laptop to be charged. At first, I thought it was the power cable, but after buying a new one, I still have the same problem. Any suggestions as to what causes this and how to fix it?
- Pulling on the cable will cause the jack to become deformed, and cause poor connections. You will have to replace the jack. On some laptops, it is an internal plug in module that is easy to replace, on others it is soldered to the motherboard, a much more expensive repair....
