It does not come with a power adapter - it is connected to mine in the photos just to show that it works but you will need either a 6v DC power adapter or a universal one or use batteries .

This has no batteries included and needs 6 C size batteries .

There are no sticks with this but any drum sticks is fine .

No instructions but information can be found online .
