The powerbank will automatically cut-off the power and go into sleep mode when it detects possibility of over-charge/ over-discharge/ short-circuit. This is sometimes due to faulty cable issue. Please activate the sleeping powerbank by charging it with its wall plug (3-pin plug) and use a good condition cable.
