The Profoto Pro-B MainsDock is the perfect solution for those who have to make the choice between the mobility of a battery pack and convenience of an AC pack. Now you can have them both. The lightweight MainsDock is multi-voltage so you can use it anywhere in the world where there's electricity. Its compatible with Pro-B2 and Pro-B3 battery packs (generators), in fact you can even use the head's modeling light. (See note) Safety features include an over temperature indicator.
Note: All Pro-B2 generators and Pro-B3 generators below serial number 1104180060 need an EOP-update to work properly with the MainsDock, otherwise they may overheat.
