battery or error code of the vehicle.
Contact AstroAI for after-sales support.
Failure to Jumpstart
Insucient power level or the jump starter is still charging.
Contact AstroAI customer support.
Failure to Power On
The object’s pressure value is too low to detect.
Normal Inflation, but the Pressure Value is Zero

ERROR CODEANALYSIS
E1
Insucient battery level.
Check if the air hose leaks.
Check if there is a good seal on the air hose’s ends.
Check if the inflating object is leaking.
Slow Inflation
Check if the charging cable is connected correctly.
Ensure the outlet is powered.
If the jump starter overheats, it will turn on its overheating protection
