Product selling points: 1. Use high-quality aluminum alloy shell, high strength, iron shell high-strength all-round protection, durable. 2. Full current, five major protections, wide voltage input, wide application range, automotive voltage converters convert unstable voltages into stable voltage outputs. 3. The cigarette lighter wiring is more convenient to plug and play, allowing you to convert DC 24V voltage to DC 12V voltage. 4. Double capacitors have stronger stability of releasing electric energy, built-in multiple protections, including overload, overheating, multi-voltage and short-circuit protection, and the cooling air outlet with iron shell has better heat dissipation effect. 5. Suitable for car audio, walkie-talkie, LED, radio, taxi advertisement, monitoring system, car display, truck, bus.
