On top of the Merlin’s well-proven performance, the new HLB25 can now operate from an internal 6V battery (not included), which can be used as a backup power source, or as the primary power supply for maximum portability. In addition, the new Merlin can be powered by a 9V dry cell or a 12V leisure battery, and the addition of an optional adpater means that you can even run the new HLB25 from the mains.
