Pros & Cons
DEWALT 12V MAX/20V MAX Lithium-Ion Battery Charger, 4 Amp (DCB1104)
Pros
- Charges both 12V MAX and 20V MAX DeWalt packs from one charger, per the manufacturer listing
- 4 Amp charge rate stated by DeWalt on the listing
- Genuine DeWalt OEM part
- Priced under $25 despite covering two voltage platforms
Cons
- No fuel-gauge or diagnostic display
- We haven't independently timed a charge — 4 Amp is the manufacturer's stated rate, not something we measured
- FlexVolt 60V packs are not listed as compatible
Ryobi 40V Battery and Charger Kit, 4.0 Ah Lithium-Ion Battery Set OEM OP4040 + OP403A
Pros
- Bundles a 4.0Ah 40V battery (OP4040) with a charger (OP403A) in one genuine Ryobi kit
- 4.0Ah is a mid-to-high capacity pack for the 40V outdoor-power platform
- Currently in stock on Amazon
- Genuine Ryobi OEM parts, not aftermarket
Cons
- Only one battery included — no second pack for hot-swapping on longer yard jobs
- 40V packs are heavier than ONE+ 18V packs, worth weighing if you're carrying it around
- We haven't independently timed a charge or measured runtime; 4.0Ah is Ryobi's stated rating
