Buck converter: Input voltage: DC 18V; Output voltage: DC 12V; Output current: Max 10A; Max output power 120W. Our voltage buck converter adopts synchronous rectification technology to further improve conversion efficiency and good stability. : Equipped with smart chip of voltage regulator, it provides intelligent protection of overcurrent, overload, low load, overvoltage, undervoltage, overheating and short circuit. We upgraded the low voltage protection, this voltage converter has built-in over-low voltage protection, if the battery voltage is lower than 14.4v, it automatically shut down to protect the device from over-power damage. High quality and easy to use: DC 18V to DC 12V buck converter is made of High-quality materials shell, epoxy resin potting, waterproof, dustproof, moisture-proof, shockproof, better heat dissipation, more . We combine the battery adapter and voltage converter with 2 heat- wires. It is more convenient to use. Just install the battery to the battery adapter and connect the voltage converter to the device. Widely Used: This step-down converter is suitable for 12V devices, perfect for upgrading motors, ride-on toys, golf carts, cars trucks, speakers, surveillance equipment, power tools, LED light bar lights, work lights or robot DIY, etc. Warning: This product is not a charger, it only output battery voltage and power directly from your battery. It is best to remove the battery after use. Adapter Compatibility: Red for 18V Battery, 48-11-1865, 48-11-1880, 48-11-1820, 48-11-1828, 48-11-1811, etc.Our battery adapter connector is beautifully designed, fits your battery tightly, easy to install and remove.
