TheFenix ALF-18 adapter allows you to use the 18650 cell in selected flashlights powered by the 21700 battery.

What is the Fenix ALF-18 adapter used for?

In some models of Fenix flashlights, it gives the user the opportunity to use an alternative, more popular form of power supply - that is, 18650 batteries. Thus, when the 21700 battery is depleted, in selected flashlights we can replace it with an 18650 cell.
Its use does not require interference with the flashlight's design. It is enough to insert the 18650 cell into the adapter (with the plus toward the plus) and so prepared battery pack put together in the flashlight.

The adapter is made of high-quality plastics in the form of PC and ABS. To ensure excellent conductivity and reduce current loss, the positive terminal contact is coated with copper.
