Is it okay to plug a power-strip into a UPS?

Power strip, sure if you don't exceed amperage, etc.

I've heard that the stepped wave can damage the MOVs in a surge
supressor and turn it into a power strip w/ no surge protection.  I've
also heard that there may be no indication that it's ruined.  YMMV.

So use a (less expensive) power strip, not a surge supressor to add
outlets.  The UPS is already a better surge supressor anyways.
