  • USB2 hub with 12V power supply.

    I need a USB hub, but I do not want to put it though the invertor. Is threre anything on the market with 12V connector, so I can hook it directly to the car power.

    Are you sure it takes 12V in? Most take 5V in at 2 or 2.5A...Regardless of the input you could get 12V or 5V from your PSU in the computer. Just run the wires.

      I'm looking for the same thing. I'm running a laptop for my carputer so I don't have a source for 5 vdc. I've purchase a car power adapter but it only give 500mA. Need something with more current. Anybody?

                Here's what I installed last weekend. Doesn't provide a ton of power-uses a second usb port for additional power. Easy install and solved my problems that I had with unpowered hub.

                  Check out this one:
                  http://www.monoprices.com/products/p...seq=1&format=2

                  It has a wall-wart power supply that supplies the hub with 5v DC @ 2.6a. You could wire it to a molex connector and plug it into your PC power supply.

                    Looking for power from a 12VDC power to 5VDC with something >2 amps. THERE IS NO SOURCE FOR 120VAC!!!

                      Sorry dude, I know that the hub I linked is NOT 12v. My point was that you could wire it to the 5v rail off your PC power supply without much trouble. No need for an invertor any any of that.

                        I bought a cigarette lighter one at WalMart that was voltage adjustable from 3, 4.5, 5, 7.5, 9 and 12 I think.

                        It supplied quite a bit of power too.

                          I'm running a laptop, so I don't have access to 5vdc. I've already tryed the walmart power inverters but it only puts out 500mA. Need something ~2A to power my pccard 4 port usb 2.0 card and usb 2.0 dvd cd-rw.

                            You could make your own easily.
                            A 7805 regulator is 1 Amp in the TO220 case.
                            The T-3 case is up to 3 or 5 amps, I can't remember.

                            Even with minimal knowledge, you could build this. It uses a minimal amount of components.

                            If you are unsure how, RS use to sell little books for a buck that would show you how.

                            That with a couple capacitors on the input and output and you should be good. I would usually put a 4700uf at the input of the regulator (or two I may do if you go with the 3 amp regulator and a .1uf at the output. (Tantalum on the .1uf if available is what I used). I'm always paranoid and use cap's rated higher at 35 volts at the input. Just be sure to use a HEATSINK!!!

                            Tantalum not listed, but they may have.
                            RS I think only caries the 1 AMP 7805, but you should be able to find the 3 AMP one elsewhere.

                            Others may argue my way, but it hasn't failed me yet...

                            I'm sure someone will correct my typo's where I have them first...

                            This is just my opinion and you should research anything you decide to do above...

                              That stuff is too deep for me =( I'm lost. Maybe you can post a diagram of what you're talking about. Thanks
