Yes, you need one and probably already have one. A power supply is what gives power to a charger. Chargers need DC current to work. Some Pro and most sport chargers are AC/DC, which means that they have a AC to DC converter built in. This also means you can either plug them into the wall outlet, or you can power them with a power supply. DC only chargers require a power supply. RC power supplies are designed to give "clean" DC power, that is good for charging our batteries. They will run from $70-175. A good 10 amp power supply is all that most people need. You can get one from integy for ~$80. Another good power supply is the Rivergate Bulldog 15 amp. You can get one directly from Rivergate for under $100. www.rivergatedist.com

i have a ac/dc charger that is digitla and all and at the track some people use extention cords and plugins but some have power supplys (like a turbo thing) so i just need to use the wall outlets @ the race track and not need to spend 100 on a special power supply.

correct, if your charger has a 110v wall plug, you don't need a separate supply.

Chargers are much more efficient on DC current, also adding the supply inside the case makes for a bigger unit and it will run hotter which makes it even less efficient..

Either the internal P/S is crappy or it gets really hot..... maybe both, but you will notice a very big difference if you stop using the wall outlet and start using an external P/S......
