This is a 2 pin type transformer/power supply / Power Adaptor which comes in different designs in shape, but all work the same, 3 example designs are shown in product pictures above but there are more types produced, smaller and bigger all to same internal spec.
The recliner will have a 2pin lead running from motor to this transformer unit, this is 1 flat and 1 round as pictures show.
The Battery Back up option is usually fitted to the longer type unit as per photo 3 and 4, this is for emergency power back up should there be a power cut there will be limited power in batteries to lower the recliner back to closed position.
We supply the power cord with this transformer free of charge, this is usually a separate component part which we also sell individually as JM75.
This design is used on major retailers such as SCS , DFS , Harveys , Sofaworks , marks and Spencer's , john lewis and most other furniture stores.
