Product Description:

【Compatibility Important Notice】:
The adapter is not suitable for Hitachi 18V cylindrical socket-type tools, and it is also incompatible with Metabo EU version 5-PIN Older Style 18V tools. Regarding battery installation, it is not compatible with Porter Cable, Craftsman, Black and Decker batteries. Due to different configurations, they cannot be shared. Note: Before using the nail gun tool on the adapter, nails must be installed in advance to ensure proper detection and tool activation.

【2-Pin Connection Explanation】:
Due to brand-specific charging system differences, the adapter retains a 2-pin connection, removing charging and detection system pins for compatibility.

【Distinguishing Between 18V and 20V】:
Differentiating between 18V and 20V MAX batteries is essential. Most 18V or 20V MAX battery packs consist of the same configuration of 5 "18650" or "21700" cells in series or in multiple layers. The standard voltage of a single cell is approximately DC 3.6V. When these cells are connected in series, the voltage adds up; for example, 5x 3.6V = 18V. Similarly, the maximum power voltage for a single cell is 4.2V, and when connected in series, 5x 4.2V = 21V. In conclusion, whether it's labeled 18V or 20V MAX, these battery packs are composed of the same cell configurations, with no actual difference. The voltage designation varies based on branding preferences.
