Our Verdicts
DEWALT 12V MAX/20V MAX Lithium-Ion Battery Charger, 4 Amp (DCB1104)
Covers both of DeWalt's smaller-format platforms in one genuine charger at a fair price — a practical pick if you own both 12V MAX and 20V MAX tools.

A genuine RYOBI 40V pack for the outdoor-tool side of the lineup — solid capacity for mowers and trimmers, though stock availability has been inconsistent.
