Walking onto the Flight Deck I noticed two battery chargers; similar to what you can purchase as a way of charging electronic devices like an iPad; sitting on the counter between the relief pilot seats. The devices had a sticker saying PROPERTY OF [Company] NO UNAUTHORIZED REMOVAL FROM AIRCRAFT. Both items had registration numbers.I have never seen these items before on the aircraft nor has there been any documentation I am aware of dealing with these.I called operations to have them query maintenance about these.  Operations informed me that the items were to stay on the aircraft as required but what the sticker said on the chargers but maintenance could find no reference for the items; nor what they are for or where they are to be stowed on the flight deck. We stowed the chargers in the storage compartment between the relief pilot seats.I have a few questions. Are these chargers part of flight deck equipment and such are part of the preflight equipment check?  Are these devices authorized for charging our company issued iPads? Where are the devices to be stored at completion of the flight? Who is responsible for charging the devices? These items seem like an another adhoc way of keeping the company iPads charged while awaiting the permanent charging configuration for this aircraft; but it would have been nice to have a bit of a heads up that these devices are going to be deployed to the fleet.
B777 First Officer reported there were no company instructions or procedures for two unfamiliar device chargers in the cockpit.
