"Come in handy"

Quando alguma coisa "comes in handy" é porque veio a calhar, apareceu em uma hora em que você precisava, ou seja, chegou em boa hora. 

Eg:

"This outlet adptor did come in handy today. I would never have turned my laptop on without it. The battery had already gone dead."

"Bob's screwdriver came so in handy today. I left my tool box in John's car."

What has come in handy lately to you?
