Milwaukee 48-59-1808 M12 and M18 12V/18V Lithium-Ion Multi-Voltage Rapid Battery Charger

Pros

  • Compact footprint for a toolbox or job box

Cons

  • Listed as non-retail/bulk packaging — no retail box or included manual
  • Manufacturer listing doesn't state charge time or amperage, so we can't quote a speed
  • Amazon listing shows check-availability status rather than guaranteed in-stock
