4-Slot Battery Chargers | Lumen Vault

A 4-slot charger is the practical choice once you're managing more than a couple of batteries: a household with several torches, a headlamp plus spares, or a small collection of 18650 or 21700 cells that all need topping up on the same schedule.

For an even larger set of batteries at once, see our 8-slot chargers; for just one or two, our 1-slot and 2-slot pages are the simpler, usually cheaper option.
