The V20 Dual Port Charger and 4-Battery Kit charges two batteries and a USB-compatible device (2.1 Amp MAX output) simultaneously, giving you the power to complete your DIY projects. It is built to charge compatible CRAFTSMAN V20 lithium-ion batteries for shop, home, and jobsite use.
What does the dual-port function on the CMCB2011-4C mean in practice?
The CMCB2011-4C charges two V20 batteries simultaneously in two slots, plus includes a USB port for charging a phone or device at up to 2.1A. If you run two or more V20 tools — a drill and a jigsaw, or a trimmer and a blower — dual-port charging cuts idle time by refilling both packs at once instead of sequentially.
What does the kit's four 1.5Ah batteries support in real use?
Four 1.5Ah batteries give you four packs to rotate, which reduces downtime on light to moderate tasks. They are best matched to lower-draw tools — drills, drivers, and circular saws on short sessions. For outdoor tools like mowers or blowers that draw more current, 4Ah or 5Ah packs extend each run significantly.
Who is the CMCB2011-4C the right pick for?
The 4-battery dual-port kit suits someone building a V20 setup from scratch who wants multiple batteries and a charger in one purchase. It is also practical for households where two people use tools on different jobs and need to keep packs rotating without waiting on a single charger.
Can the CMCB2011-4C charger charge 4Ah or larger V20 batteries?
Yes. The dual-port charger works with the full V20 lineup regardless of capacity. The 1.5Ah packs included in the kit charge fastest; larger 4Ah and 6Ah packs take proportionally longer but are fully compatible.
Does the USB port on the CMCB2011-4C work while charging batteries?
Yes. The USB port and battery charging ports operate simultaneously, so you can top off a phone or Bluetooth speaker while the two battery slots are charging. The USB output is rated at 2.1A maximum.
