Our Verdicts
Milwaukee M12 REDLITHIUM 2.0Ah Battery (2-Pack) & Charger Kit
A genuine Milwaukee M12 two-battery-and-charger kit is the straightforward, warranty-backed way to get started or restock on the M12 platform — not the highest capacity, but the safest default.
RYOBI ONE+ 18V Fast Charger (PCG004)
A genuine Ryobi ONE+ charger marketed for faster charging than Ryobi's base charger, though stock has been inconsistent — worth grabbing when available if you're staying within the ONE+ ecosystem.
