It’s a plug-in.  I figured it would have a battery pack so I could hang it on my door (this is very disappointing) even if I could find another place for it the cord is barely 2 feet!  The colors are pretty, but there’s little styrofoam bits that are broken off so you can see the bright white centers.  I couldn’t possibly recommend this wreath, I only purchased it to have a lit wreath on my door so I would like other shoppers looking for the same thing to know that’s not what this is!
