Our Verdicts
DEWALT 12V MAX 2.0Ah Battery (DCB122)
The DCB122 is the genuine, budget-friendly entry point for DEWALT's 12V MAX platform — right-sized for compact tools, not a fit for the 20V MAX lineup.
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.
