2-Slot Battery Chargers | Lumen Vault

A 2-slot charger covers the most common real-world need: charging a spare battery alongside the one currently in use, or topping up both cells from a two-battery flashlight in one go. Several of the chargers on this page double as a power bank too.

If you regularly run more than two batteries at once, our 4-slot and 8-slot chargers cover higher-capacity charging.
