I am looking for a source for a laptop power tip.   Children are hard on equipment, and I have a perfectly good power adapter and no tip.  I'd like to find specifications for each tip plus a source to purchase them.

Not sure where you will get only the tip.  My kids have killed 3-4 adapters, I have had good success getting them here:

But it is the entire adapter.....

Like you, my kids kill their adapter on a regular basis (in fact, the broken one now I ordered from spareparts.  

I have a hard time spending $30 for a new adapter when I know the tips are out there.

Only other thing is to get extras when you can.  In NJ we have these computer shows.  They used to be a big deal until the Internet availability of parts killed them.  I go to them and browse the junk.  I have gotten 1 or 2 extra used adapters for like $5 at the shows.  Problem is that it is hit or miss....

They are referred to as a Barrel plug, or DC power jack.
You will have to know the dimension of the outside barrel and the inner pin connector in order to get the proper fit.
You may also be able to get a reference from the laptop model as well. If you post the model number of the laptop or also the model of the original power supply, we may be able to give a more precise answer.

For what it's worth, once you start looking for barrel plugs, you can find the connectors in various catalogs.  I ordered two for .90/each from DigiKey.  They are a PITA to solder, but 90 cents is a lot better than a complete charger.

Once I found the type of part, I borrowed a micrometer at work to measure the inner and outer dimensions.
