Doorii, a lithium battery company founded in 2009 by a group of engineers and scientists from top universities around the world, aims to provide easy and trouble-free solutions for automotive emergencies, as well as strive to deliver inventive products and improve the driving experience.

The Q10 jump starter, with its 4000A peak current and reinforced smart clamps, can reliably start 12V batteries easily and safely in 1-3 seconds. It can jump vehicles up to 10.0L Gas/ 8.0L Diesel engines, making it suitable for large capacity vehicles like trucks, boats, pickups, as well as supporting motorcycles, speedboats, yachts, touring cars, lawnmowers, RV, SUV, off-roader, sedans, and jet ski. A fully charged Q10 jump starter can provide up to 60 jumps.

The Doorii Q10 digital air pump supports smart preset & auto shut-off without repeated adjustment and check. Its unique intelligent chip makes it more powerful, more stable, and less noisy, providing fast and proper inflation to various tires, balls, and other inflatable objects. The friendly design includes real-time data reading, a detachable extended air hose, and 4 optional unit switching for convenience.

Unlike traditional jump starters that only have analog indicators, the Q10 jump starter boasts a large and intelligent smart screen, which provides you with important data such as battery level, inflator mode, and real-time tire pressure, making it more easier and clearer to use the product.
