Great little speaker!
Bought this for my son for his birthday. He loves it! He owned a previous version but it was stolen and he wanted to replace it with the same. He uses it at chess club at his university in a public space and it works well!

No charging cable in box
It did not come with a charging cable but we found one around the house that worked.

Great speaker
Pairs easily with my other Wonderboom, sounds great, charge lasts a long time, and the sound fills the room!
