As you can imagine, my car kinda looks like my desk at home - a real tangle of wires. When I got my new car I tried to clean it up a little.
What I needed was a cigarette lighter splitter for my console box. I found one at Meritline for $4.99 (now $3.99) with free standard shipping (from Hong Kong).
This has worked fine. Some plugs are a little loose in the sockets but I haven't found that to be a problem so far. Notice that it has a USB power socket too.
