1. Durable Material: Features an ABS plastic shell with strong overall compression resistance. The goldplated treatment ensures longlasting durability, making it especially suitable for frequency use in professional work scenarios. 2. Compact and Convenient: This battery converter adopts precision molding to create a cardlike body, featuring a small size and lightweight design. It can easily fit into a toolkit compartment for portability. 3. Intelligent Protection: Equipped with a builtin tripleprotection chip against overcurrent, overvoltage, and short circuits, enabling realtime monitoring of current fluctuations. It automatically cuts off the circuit upon detecting abnormalities, effectively preventing battery overload or tool motor burnout. 4. Safe to Use: The circuit board is fully encapsulated in thermally conductive silicone, enhancing heat dissipation efficiency. It operates stably across a wide range of temperatures and performs reliably even in harsh environments such as dusty or humid conditions.
