Chargers, differing in speed and in how many packs they take at once. A single rapid charger is enough for one machine. A duo charger handles two packs, which is what keeps a saw running continuously — one working while one charges. The Systainer-mounted multi-charger takes four and stacks into the rest of the kit, which suits a van where charging happens between jobs rather than overnight.
