Product Description
-
Do I need to charge the JS-40 car battery booster before first use?
YES! Although it comes fully charged at the factory, there will be some power loss during transportation. It is recommended to using the included USB-C cable and a compatible wall adapter charge it for 24 hours to activate it before first use.
-
How do I use the air compressor to inflate tires or other items?
Connect the air hose to the compressor port, select the appropriate preset inflation mode (Car, Motorcycle, Bicycle, Ball, Custom), and set your desired pressure. The unit will inflate until it reaches the set PSI and automatically shut off.
-
Is the blower strong enough to inflate large inflatables like boats or air mattresses?
YES! The blower mode is designed for light-to-medium inflation and air movement, such as swim rings, inflatable boats, air beds, vacuum storage bags, and BBQ charcoal blowing. It is NOT intended to replace a high-power household air pump.
