WorCraft 20V 4.0Ah Battery — ONE FOR ALL, USB-C Output

More runtime, more power, and a built-in USB-C port that turns your battery into a jobsite charger.

The WorCraft 20V 4.0Ah Battery (CLB-20V-4.0SC) is the high-capacity pack for the ONE FOR ALL system — built on premium 21700 cells to run every WorCraft 20V tool, including high-draw tools like the router and mini circular saw that the 2.0Ah can't power. An LED capacity gauge shows remaining charge at a glance, and the USB-C output (5V/2A) keeps your phone or device topped up without a separate adapter.

Built for Longer Runtime — and More

The 21700 cell format delivers higher energy density than standard 18650 cells — more runtime in the same compact form factor. Whether you're running the router through hardwood, cutting sheet goods with the mini circular saw, or grinding through a long session with the angle grinder, the 4.0Ah pack keeps up where the 2.0Ah taps out.

Frequently Asked Questions

Q: Which tools does this battery fit?
Every tool in the WorCraft 20V ONE FOR ALL range — including high-draw tools like the router and mini circular saw that require a 4.0Ah or larger pack.

Q: Can it charge my phone?
Yes — the built-in USB-C port (5V/2A) lets the battery double as a portable charger for phones and 5V devices directly on the job.

Q: Is it compatible with my WorCraft charger?
Yes — it charges on all WorCraft 20V ONE FOR ALL chargers, including the 2.4A charger (CLC-20V-2.4U). Approximate charge time is 1.5–2 hours from depleted.

Q: What's the difference between the 2.0Ah and 4.0Ah?
The 4.0Ah offers roughly double the runtime and powers high-draw tools the 2.0Ah can't handle. The 2.0Ah is lighter and better suited for overhead work and lighter-duty tasks.
