Why drivers keep it close

- 3-mode emergency light: Useful when working around your vehicle in low light.
- USB power options: USB-C input for charging the unit and USB-A output for compatible accessories.

Frequently asked questions
Will it jump-start every car?
No. The YD09 is designed for compatible 12V vehicles. Supported engine sizes, peak starting current, battery chemistry and operating limits must be checked against the supplier manual before use; no 4000A rating is claimed for this variant.
Can I inflate my car's tires to 150 PSI?
Never inflate based on a device's maximum rating. Follow the tire pressure specified by your vehicle manufacturer, usually shown on the driver's door placard.
Is it easy to store?
Yes — the YD09 main unit measures approximately 8.6 × 3.6 × 1.9 in. Keep the unit and necessary cables in a secure, dry place, away from extreme heat.
When will it arrive?
Delivery depends on supplier processing, stock, the shipping service and your ZIP code. Check the shipping option and estimated dates at checkout; we cannot confirm a 5–7-day total delivery time for this exact packaged version without supplier evidence.

The exact included cables, air hose, adapters, carrying case and accessories depend on the supplier's packaged version. Please confirm the contents stated for the specific item before ordering; do not assume every accessory visible in an illustrative image is included.
Care and safety
Read the instructions before connecting jumper clamps. Confirm correct polarity and compatibility. Do not use a swollen or damaged battery or cord. Do not leave the battery pack in extreme heat. Power and inflation performance vary with temperature, battery condition and connected equipment.
