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

Pros

  • Charges both M12 and M18 REDLITHIUM packs from one charger, useful if you own tools on both platforms
  • Genuine Milwaukee OEM part, not a third-party clone
  • Priced under $60, cheaper than buying a dedicated charger for each platform
  • Compact footprint for a toolbox or job box

Cons

  • 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

Our Verdicts

DEWALT 20V MAX Compact 2.0Ah Battery (DCB203)

The DCB203 is DEWALT's genuine compact 20V MAX pack — the cheapest way into real DEWALT chemistry, best suited to light tools rather than heavy-draw ones.

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

If you run both M12 and M18 tools, one charger that handles both packs is a real convenience — this is a genuine Milwaukee part at a fair price, though stock availability varies.
