Our take on the Craftsman 20V to Kobalt 24V Battery Adapter

This adapter lets Craftsman 20V lithium-ion batteries run Kobalt 24V cordless tools from Lowe's. It steps the battery's voltage up to 24V at the tool rather than passing 20V through, and it carries battery protection electronics inside. The housing is injection-molded ABS with a 3D-printed ABS tool socket and pure copper contacts, rated 55A continuous and 100A peak. It suits owners already on the Craftsman 20V platform who want to use Kobalt tools without buying a second battery line.

About the Craftsman 20V to Kobalt 24V Battery Adapter

This adapter lets Craftsman 20V lithium-ion batteries power Kobalt 24V cordless tools. It converts the voltage rather than passing it through, so the tool receives 24V from a 20V battery. It works in one direction only: Craftsman batteries powering Kobalt tools.

The battery interface is injection-molded ABS. The tool socket is 3D-printed ABS, and the contacts are copper. A built-in battery management system (BMS) cuts power before the battery is drained too far.

The adapter is for powering tools only. It cannot charge batteries and must never be connected to a charger. Remove the battery from the adapter before charging, and charge it on the original charger made for the Craftsman 20V battery. Use a battery of at least 3 Ah, with 4 Ah or more better, because a smaller battery can sag under a higher-voltage tool until its own protection cuts out.
