Arrancador BlitzWolf BW-JA1 power bank portátil 20000mAh com função de arranque

Blitzwolf BW-JA1 20000mAh Car Jump Starter with Compressor is a compact multi-function roadside device combining a high-capacity 20000mAh power bank, a 2500A peak-current jump starter for 12V vehicles, and an integrated air compressor with a maximum pressure of 150 PSI. Designed for use in temperatures from -20℃ to 60℃, it can start gasoline or diesel engines up to 8.0L and offers a built-in 120LM LED flashlight and an LCD screen for convenient monitoring.

Advantages

The BW-JA1 unites jump-starting, tire inflation and device charging in a single lightweight unit (780g) with compact dimensions (220 x 95 x 89mm). Fast-start clamps and a strong peak current ensure reliable engine starts in seconds; the compressor reaches 0–36 PSI in about 3 minutes and can quickly top up typical car pressures. Smart presets, automatic shutdown and an included adapter kit expand usability to bicycles, air mattresses and toys. Two USB ports provide fast charging for phones and accessories while the LCD shows pressure and status data.

For tire inflation, attach the air hose and select the desired pressure preset on the LCD; the compressor inflates from 0 to 36 PSI in approximately 3 minutes and will stop automatically when the target is reached. Use the USB ports to charge phones and accessories as a 20000mAh power bank. Keep the device dry, avoid extreme impacts and store it in the included carrying case when not in use.

Recommendations

The BW-JA1 is intended for 12V vehicle use and is not suitable for truck tires. Regularly check clamp connections and battery charge level before long trips. Use the provided adapters for inflatables and refer to the LCD prompts to select correct pressure units and presets.
