Super Powered Equipments that Grants Super Powers

[Shishiwashi]

Thank you for the interesting suggestion, Mr. Beer.

Are you implying that, since Advantages/Disadvantages like "Invisibility for the Item" doesn't help the user, but the Equipment, they should be treated as Perks/Quirks? If so, how would the character pay for them?

To be more specific, I've written an example below:

Invisible ring that grants the wearer +2 points of Strength. +2 points of Strength are 20 character points and the Invisibility Perk is 1 point. Adding Breakable (-20%), Can Be Stolen (-30%) and Unique (-25%), its cost will be 6 character points (21*0.25 round up).

Should my character pay those 6 points? What if I lend my ring to a friend, and he gives it back to me afterwards? My friend will use those powers freely while he has the ring? Even if it was me who paid for them? And will I be able to use them normally after I get my ring back? Those are the things that confuse me.

And what if I have an equipment with Regeneration (Fast), 1000 DR, and 100 Extra Lives? Those are all "Equipment Advantages", but I cannot simply treat them as perks. An equipment with 1000 DR should cost differently than an equipment with 0 DR.

So how should I charge those "Equipment Advantages"?

EDIT: At the time I finished writing my response to the first comment, a lot of people had already commented, bestowing the answers I sought upon me.
Thank you all for all those kind suggestions, now I have a place to start; more than that, actually.
