Oladance Charging Case for OWS 1 & OWS 2, 2550mAh Grey Galaxy (EARBUDS NOT INCLUDED)

This is my personal case. I have charged both OWS 1 and OWS 2 earbuds in this case. For me, the case has completed approximately 6 - 8 complete recharges of the earbuds (many times the earbuds being almost completely dead) before needing to be recharged itself.
