Albert, The 110 volt converter that comes with most hubs puts out a specified DC voltage for the USB hub to run. 5 volts DC, I think I was able to find a selection of cig lighter plugs adapters to match the input voltage of the hub I bought. Several are variable DC voltage output The tip size of the power input to the hub is the hardest part to match up. Radio Shack has variable voltage output cig corded systems with multiple power tips to choose from. You can buy just the tip you need by taking the USB hub with you, or buy them both at R Shack so you have everything in your hand and know it will work. Just find the input voltage for the hub, select a cig plug voltage adapter and make sure you get the proper sized input tip. I ended up buying both at R S for convenience. It was very hard to find input power tip sizes on the internet. Of course, I don't use it anymore since the new laptop has more USB ports.

Can anyone recommend a good one? Most of what I see on line is either powered by the laptop or has a transformer utilizing a 110 plug.
