- Amazon listing shows check-availability status rather than guaranteed in-stock

- Marketed by Ryobi as a 'Quick Charger'
- Affordable at under $30

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.
