i have an eflite power supply that came with my Blade CX heli. I've been wondering if I can use it to power my Kokam Lipo403 charger, and charge 3 cell lipos with it. right now i'm using my 12v gell cell. the power supply reads, output 12v 1.5 amp.

1.5A (1500mAh) is barely enough to run the charger itself, never mind to actually charge a battery.

You need a power supply with at least the current capacity of the largest battery you'll be charging, plus additional capacity for the charger itself. A 12-volt 10A power supply is a good choice as a starter supply for charging small packs.

In my experience, you'll never regret buying a larger power supply than you presently need.

thanks. i suspected that. any suggestion on an inexpensive power supply?

There are dozens of suitable power supplies available. Probably the most readily available are those from Radio Shack, [link=http://www.radioshack.com/product/index.jsp?productId=2103960]such as this one[/link]. Radio Shack products aren't necessarily the best value, but they will usually do the job.

Hopefully, others will suggest specific models from other companies.

Note that "12-volt" power supplies usually have an actual output of 13.8V, which matches the voltage of a typical car battery.
