Key Details

The pump features a digital control panel with the following components:

Component	Function
Power Button (01)	Turn on/off, start/pause inflation
Unit Button (02)	Switch between BAR, PSI, and KPA units
Mode Button (03)	Toggle between LOW and HIGH pressure modes
+ Button (04)	Increase target pressure value
– Button (05)	Decrease target pressure value
Inflation Port (06)	Connect air hose for inflation (marked INF)
Deflation Port (07)	Connect air hose for deflation (marked DEF)
Digital Display	Shows actual pressure (large number) and target pressure (small number)

Operating Modes:

LOW Pressure Mode: For large-volume items like inflatable pools, kayaks, and tents. No preset pressure value.
HIGH Pressure Mode: For high-pressure items like SUP boards and rigid inflatable boats (RIBs). Default preset: 3 PSI.

Unit Conversion: 1.0 bar = 14.5 psi = 100 kPa = 1.0 Kg/cm²

Standards & Compliance

The Vortex S4 is designed with multiple safety features and operational standards:

Temperature Protection: Automatic shutdown when operating temperature exceeds safe limits (-20°C to 60°C)
Low Voltage Protection: Visual indicator when input voltage is below rated value; device continues to operate with reduced efficiency
Pressure Accuracy: ±0.5 PSI sensor tolerance ensures precise inflation
Auto-Stop Function: Pump automatically stops when preset pressure is reached
Memory Function: Device remembers previous pressure settings and unit preferences
Altitude Calibration: Manual recalibration available for high-altitude use (above 5000 feet / 1524 meters)

Safety Certifications: The device includes built-in protections against overheating, overpressure, and electrical faults. Error codes (E02, E04, E05, E07, E10) provide diagnostic information for troubleshooting.

Frequently Asked Questions

How do I switch between PSI, BAR, and KPA units?

Press the Unit Button (02) briefly to cycle through the three pressure units: BAR, PSI, and KPA. The selected unit will be displayed on the screen. The pump remembers your unit preference for future use.

Why does the low voltage indicator flash when I start the pump?

The low voltage indicator flashes when the input voltage from your vehicle is below the rated value. The pump will still operate but with reduced efficiency. For optimal performance, start your vehicle engine before plugging the pump into the cigarette lighter socket to ensure adequate voltage supply.

When should I use LOW pressure mode versus HIGH pressure mode?

Use LOW pressure mode for large-volume items that require less pressure, such as inflatable pools, kayaks, air mattresses, and tents. Use HIGH pressure mode for items requiring firm inflation up to 20 PSI, including SUP boards, rigid inflatable boats (RIBs), and high-pressure camping equipment. The HIGH mode has a default preset of 3 PSI which you can adjust.

How do I calibrate the pressure sensor for high-altitude locations?

If you are at altitudes above 5000 feet (1524 meters), pressure readings may vary by 1-3 PSI. To recalibrate: (1) Connect the pump to the cigarette lighter power source, (2) While powered on, simultaneously press and hold the Unit button (U) and Mode button (M) for 10 seconds, (3) The screen will restart, confirming successful recalibration.
