Firstly ensure the wall charger is plugged into a functioning power socket and the charge connector is properly connected into the Grabba. If so leave the Grabba on charge and wait for up to 2 hours. If the Orange charge light comes on during this period then the Grabba must have been extremely flat and the 2 hours was needed for trickle charging for battery protection. You should now charge the Grabba overnight.
I plug the charger into the Grabba and I don’t see any lights Luke 2018-02-23T13:09:20+00:00
