The Dual-Port Charger allows you to charge 2 CRAFTSMAN V20 batteries simultaneously. It is built to charge compatible CRAFTSMAN V20 lithium-ion batteries for shop, home, and jobsite use.
What does the dual-port design on the CMCB124 mean for a V20 setup?
The CMCB124 has two charging slots that operate simultaneously, so you can refill two V20 batteries in the same window instead of charging them back to back. For anyone rotating packs across a drill and trimmer, or completing mowing and blowing in the same session, the time savings add up quickly.
What charge rate does the CMCB124 run at, and what does that mean for battery wait times?
Each port runs at 2.1A. A 2Ah pack finishes faster than a 4Ah or 6Ah pack, which takes proportionally longer at the same amperage. The dual-port design compensates: while one battery finishes, the second is already mid-charge, keeping idle time short.
Who should buy the CMCB124 versus the single-port charger included in most V20 starter kits?
The single-port charger is adequate if you have one or two packs and rarely run back-to-back sessions. The CMCB124 makes sense once you own three or more V20 batteries, use tools across multiple tasks in the same day, or need a dedicated charging station separate from the one that came with your kit.
Does the CMCB124 work with all V20 battery capacities?
Yes. The CMCB124 is compatible with any V20 slide-pack battery from 1.5Ah to 9Ah. Both ports accept any capacity simultaneously — you can charge a 2Ah and a 6Ah at the same time without issue.
The CMCB124 ships without batteries — who is that the right buy for?
A standalone charger makes sense when you are adding a second charging station to an existing V20 setup. If you are starting fresh with no batteries, a kit like the CMCB204-CKVA or CMCB202-2CK bundles batteries and a charger together and is a better entry-point purchase.
