Pros & Cons

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

  • 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

RYOBI 40-Volt Lithium-Ion Quick Charger

Pros

  • Genuine Ryobi OEM charger for the 40V platform
  • Marketed by Ryobi as a 'Quick Charger'
  • Affordable at under $30
  • Compact, single-port design

Cons

  • 40V only — will not charge ONE+ 18V or M12/M18 packs
  • No published amp-hour charge spec beyond the 'quick' branding

Our Verdicts

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.

RYOBI 40-Volt Lithium-Ion Quick Charger

A genuine, budget-priced Ryobi 40V charger branded for quicker charging than Ryobi's standard unit — a sensible spare or replacement for the 40V outdoor-power platform.
