Question 1

Does this fit macbook?

Accepted Answer

I only have PC's, but this product came with numerous adapters for different sizes of power plug-ins.  If you're uncertain, perhaps call or email the manufacturer.

Question 3

How do I buy replacement tips in case of damage?

Accepted Answer

good question I searched the rosewill site and the internets it does not look like rosewill sells them.  maybe if you call them...  maybe the cord is compatible with other manufacturers tips try walking into a local radioshack with the power adapter if you already bought it to see if any of their tips will fit...

Question 4

Does it have the 3.0mm*1.1mm tip size that fits Samsung notebook model # NP300U1A-A01US  ?

Accepted Answer

I'm not sure it has what you are looking for.  It comes with a chart to show which tip fits what.  It's a good start, but I have found the "Poke & Hope" method works best!  I have not found a laptop/desktop that I have have yet to get to power up.

One of my best computer toolbox investments ...
