The LD-458 Lithium 12V Car Emergency Jump Starter (K38) is a multi-function portable power device that combines a lithium-ion jump starter, a USB power bank, and an air pump in a single compact unit. Designed for drivers, fleet operators, and outdoor enthusiasts, it provides emergency starting for 12V vehicle batteries, mobile device charging, and tire inflation in one carry-anywhere package.

The lithium-ion battery is available in 10000mAh to 20000mAh capacities, delivering peak starting currents from 1000A to 2000A. This range covers gasoline engines up to large-displacement V8s and diesel engines up to mid-size, making the K38 suitable for passenger cars, SUVs, light trucks, motorcycles, and boats. The 12V DC jump-start output works with standard lead-acid and AGM batteries, and the intelligent safety clamps protect against reverse polarity, short circuit, over-current, and overheating.

The integrated air pump delivers up to 150 PSI for inflating car, motorcycle, bicycle, and ATV tires, with a LED digital display showing real-time pressure for accurate inflation. Needle adapters extend the pump to sports balls and small inflatables. A 5V/2.1A USB output turns the unit into a power bank for phones, tablets, and other mobile devices, while the built-in LED light provides illumination for nighttime roadside emergencies.

Certified to CE, FCC, RoHS, MSDS, and UN38.3, the LD-458 meets international safety and transport standards for lithium-ion products. The ABS housing, pure copper motor, and heavy-duty booster cables with intelligent clamps deliver reliable emergency performance for automotive, outdoor, and travel applications where a dead battery or flat tire would otherwise strand the user.
