Before you buy

Good to know before buying

  1. 01

    Cell-bay count vs cells you own

    A four-bay charger doesn't need four cells — empty bays are fine. Match bays to how many cells you cycle in a typical week.

  2. 02

    USB-C in, separate from the mod

    Modern external chargers are USB-C powered but charge independently from the mod's port. Use the wall brick the charger ships with — it has the right output for balanced charging.

Care + usage

Usage notes

  1. 01

    Don't fast-charge daily

    Most chargers offer a fast-charge mode. Use it occasionally; slower 0.5 A charging extends total cell life noticeably.

  2. 02

    Charge on a hard surface

    Soft fabric blocks the charger's vent slots and traps heat. Bedside table top, not bedside table cushion.

Who this is for
