How can I use this to step up the voltage from my alkcar battery 10v-11.3v to my laptop19v? What do I need to know, to keep this thing from frying?

Just remember not to exceed the 10a limit, I really don't recommend running it at 10a if you dont have to, and if you do, try to get more cooling. Make sure the plus and minus are the correct polarity, and (not neccessary, but recomended) put a little voltage moniter on the output, to make sure that it is not going above 19.5v

watts divided by volts will give you amps, however if your input drop below 10v you would need to readjust the blue pot screw same if it goes above 11.3I wouldn't there is a good universal on this site with a voltage select and multiple output adapters

if you can get an adapter to switch to European Volts you can try. I would not do it. Rather take a notebook with me that can be operated with only batteries.

And the sticker reads: 2.0A for BOTH the 5V and 12V output ratirings. Really a neat product. I will be fixing a friends laptop, just pulling it out of the case, setting this up and using their HDD as an external and it has always worked. This is my third order of the same product from the same source, always the same professional response. Hope this helps you. Will

Use a Isobar/Tripp-Lite UltraBlok428 and not only will all be well, your laptop will like the power produced better.

I grabbed an old mouse, cut the cable, and then stripped the red (+5v) and black (gnd/-) and soldered those into the power vias on the board (the holes on the circuit board).This chip is rated for a MAX of 5.5 volts, so DON'T try to run it from four AA or AAA batteries, you will fry it. However, the USB 5volts works just fine. Mine has been running for what, about a month now, and going strong.

HI Suriya, I am sorry to say that I don't know for sure. I am in the USA so I don't use that voltage. If you can get it to work it is a great value though. Good Luck

No. It is to be used to maintain a battery charge and is not a charger at 1.8 @ 12vdc. If your laptop operated off of 12 Volts DC then with some adapters, yes possibly, but they do not. You would be better off with a Radio Shack Inverter (12 V DC to 120 VAC) that plugs into a cigarette lighter. I used one for years for laptops and such.

No. If we are speaking of standard laptops then common voltages are 7.2V, 9.6V, 10.8V, 11.1V, 14.4V and 19V. If you have a netbook you will have to find out what voltage is needed. Be sure to get a charger that is for the type of battery you have. Lithium Ion batteries charge in stages and the wrong charger will cause it to overheat or even catch fire. Sorry for the bad news and I hope this info will be helpful

This is not a good option, I'm sorry. I suggest looking for a 10watt 12v panel that discloses the actual specifications of the unit. The output voltage is undisclosed and I had very irregular performance.Hope this helps...good luck.

Make sure to use low voltage 1.3v module. I was able to upgrade to 10gb total (installed 8gb module same brand and specs that the one I pulled out)

I don't have any experience with your keyboard, but usually you'll find a sticker near the plug that tells you what voltage and amperage it needs from its adapter. Also, if there's a little diagram that looks kind of like a "C" wrapped around a dot, pay attention to which one is labelled positive and which is negative. If you can get that info, you can just buy an adapter that matches that description and you're in business. Good hunting!

Hi, I believe you'll need to figure out what the amperage is of the power supplies that what you want to run and if anything else is running on the same circuit. I read in the reviews and elsewhere that you should use this accessory with a 15A or less fuse, so I have it on a circuit with 15A in my travel trailer. My laptop 12v power supply uses 3.5A, the Coleman 12v cooler uses 5A, the phone charger uses 1.5A I think. I have run the cooler and a charger at the same time without it melting or blowing a fuse. I did fry the last dual power outlet (different make, felt cheaper) with the same usage (Caveat: I am not an electrician and am just sharing my experience.)

I use a voltage adaptor with mine. It is a great product. It can take a couple of batches to figure it out once you do you will be making your own all the time.

Hi Xiang,First of all, I do not know much about electronics, but would like to answer what I know.The voltage of my machine is 120v which is allowed to use in my country. You need to use an AC adapter to convert the voltage if it is not allowed but most important is to consult a licensed electrician.

Question doesn't make much sense. To get more current, you'd want to step the voltage up.

This one should do the trick. It's 150w and 19.5v. It's great for my power hungry alienware. Good luck!
