To charge your Turtlebox, plug the provided wall charger into the USB-C port labeled "IN" under the port cap.  Please note that typical USB-C chargers will not charge the Turtlebox as they are 5 volts and the Turtlebox needs 12 volts.  

If trying to charge your Turtlebox in a vehicle or on a boat, you will need to use an adapter in addition to the Turtlebox charger that came with your speaker. We have included a link below to an adapter we have tested in-house which will successfully charge your Turtlebox:
