In the description you need to connect it to a charger and charge it first to activate it. Then you will have output power. But, if you are like me, I use a actual Lipo charger for my Samsung 30Q button and flat tops 18650's. By adding a jumper wire and tact switch. From the B+ to the tact switch then to the P+ and short push of the switch, the unit will turn.
