This is a great pump with a rechargeable battery. You can now pump up your kite very quickly with this electric inflator. The battery is attached to the pump and comes with the hose, the car charger. The Pump quickly pumps up your kite to the desired pressure and automatically shuts off. It comes with a water resistant pouch to protect from the elements and sand. We did find that the water resistant pouch is poorly made but this does not affect the pumping capability. You can pump up multiple kites with this bad boy. You will quickly make new friends since no one wants to pump up their kite. It all comes in a nylon case with zippers and carry strap.  The carrying case and nylon bag are not top quality but does not reflect the pump! The complete package is only about 9 pounds (4.8kg) which is much lighter than a car battery. LIGHT AND COMPACT 12"T X 6" W X 5" D

The pump has a automatic adjustable shut off and will pump at full speed for about 15 minutes. The battery will recharge in the car with the motor running in 4-5 hours and plugged into the 120V home charger it takes about 8-12 hours. Pump comes with car charger only.
It will pump up to 12 psi (800mbar) and consumes 13 Amps.
This is a super fast adjustable pressure unit and does everything I have ever wanted out of a pump. All I can say is BRAVO..  BRAVO BST 12 KITE Pump
