Technical Details

Design: The Type A (NEMA 1-15) features 2 flat parallel pins.

Safety: This plug type is rated for 110-127V electrical systems. As an ungrounded plug, it's typically used for low-power devices with double insulation.

Compatibility: Always verify both the plug shape AND voltage compatibility before using adapters. A physical adapter does not convert voltage.
