Milwaukee Four-Bay Super Charger (48-59-1818) Now at $499 — PACKOUT, COOL-CYCLE, Four Batteries in 90 Min

Checked June 30, 2026. The Milwaukee M18 & M12 Four-Bay Simultaneous Super Charger (model 48-59-1818) is now available at $499. Bay configuration: two dedicated M18 bays and two M18/M12 hybrid bays, allowing shops running both platforms to use a single charger. CHARGE ADAPT technology runs all four bays simultaneously. Charging speed: four M18 FORGE HD12.0 batteries to 100% in 90 minutes; a single battery to 80% in 35 minutes. COOL-CYCLE active cooling reduces heat buildup during fast-charge cycles. Design: PACKOUT-compatible footprint with an integrated carry handle for tool box stacking. This is Milwaukee's first charger to support M18 and M12 batteries simultaneously in a four-bay configuration. Verify current price and availability at milwaukeetool.com.

Workshop signal

For shops running both M18 and M12 tools — the standard dual-platform Milwaukee setup — a single PACKOUT-compatible charger that handles both battery families eliminates a redundant charger shelf. The COOL-CYCLE active cooling is the operational detail that matters at production pace: fast-charge heat is the primary reason battery chargers fail early. At $499, this is priced below the combined cost of two separate Milwaukee rapid chargers at current retail.

Bench notes+

Milwaukee M18 & M12 Four-Bay Simultaneous Super Charger (48-59-1818) confirmed specs (June 30, 2026): Price: $499. Bay layout: (2) M18-only bays + (2) M18/M12 hybrid bays. Charging mode: CHARGE ADAPT simultaneous (all four bays at once). Speed: 4× M18 FORGE HD12.0 batteries to 100% in 90 min; single battery to 80% in 35 min. Cooling: COOL-CYCLE active cooling system. Compatibility: PACKOUT modular system, integrated carry handle. Battery systems supported: M18 REDLITHIUM and M12 (hybrid bays). Announced: World of Concrete trade show 2026. Verify full compatibility chart and authorized dealers at milwaukeetool.com.

Market Position: The four-bay configuration with dual-chemistry support (M18 and M12) is the gap Milwaukee was closing: crews using both M18 and M12 platforms previously needed separate chargers from different lines. PACKOUT integration at $499 positions this as a production-crew and mobile-shop tool — the carry handle and stackable design extend its utility beyond a fixed bench charger. COOL-CYCLE active cooling is a differentiator from passive-cooled multi-bay alternatives.

Open Questions:
  • What is the charge speed for M12 batteries specifically in the hybrid bays — separate spec from the M18 FORGE HD12.0 90-minute figure?
  • Does COOL-CYCLE active cooling apply to all four bays simultaneously, or is it activated per-bay based on temperature?
  • What is the amperage draw at full simultaneous four-bay charging — relevant for workshop circuit planning?

Wait if: You run only M18 tools and already own a Milwaukee dual-bay rapid charger — the incremental value of two additional bays at $499 may not justify the upgrade unless you're adding crew members or expanding capacity

Buy if: You run both M18 and M12 Milwaukee platforms and need a single PACKOUT-compatible charger for both — $499 replaces two separate chargers and simplifies the tool cart setup; verify in-stock status at milwaukeetool.com or authorized dealers
