Etenwolf Vortex S7 Tire Inflator: Complete Technical Guide

Overview

The Etenwolf Vortex S7 is a high-performance cordless tire inflator designed for passenger cars, SUVs, motorcycles, and bicycles. With a maximum pressure of 150 PSI and a digital LED display, it delivers accurate, fast inflation for daily driving and emergency roadside use.

Key Specifications

  • Max Pressure: 150 PSI / 10.3 bar
  • Flow Rate: 35 L/min
  • Power Source: Built-in 2000mAh lithium battery
  • Charging: USB-C, fully charged in ~1.5 hours
  • Display: Digital LED, switchable PSI / BAR / kPa / kg/cm²
  • Auto Stop: Preset target pressure, stops automatically
  • Noise Level: ≤75 dB
  • Weight: 0.54 kg

How It Works

The Vortex S7 uses a brushless motor to drive a reciprocating piston that compresses air. The digital pressure sensor continuously monitors output pressure and triggers an automatic shutoff when the preset target value is reached, preventing over-inflation.

Preset Modes

Four built-in inflation modes simplify operation:

  • Car Mode: Default preset at 35 PSI for standard car tires
  • Motorcycle Mode: Preset at 36 PSI
  • Bicycle Mode: Preset at 50 PSI
  • Custom Mode: User-defined pressure target up to 150 PSI

Usage Instructions

  1. Remove the valve cap from the tire valve stem.
  2. Attach the inflator nozzle to the valve stem and lock it in place.
  3. Press the power button to turn on the unit.
  4. Use the +/- buttons to set your desired pressure.
  5. Press the start button — inflation begins automatically.
  6. The unit shuts off automatically when target pressure is reached.
  7. Disconnect and replace the valve cap.

Maintenance Tips

  • Store the inflator at room temperature and avoid extreme heat or cold.
  • Charge the battery every 3 months if not in active use.
  • Keep the air intake vents clear of dust and debris.
  • Do not exceed the rated maximum pressure of 150 PSI.

Compatibility

The Vortex S7 includes three nozzle adapters: Schrader valve (standard car/motorcycle), Presta valve (road bikes), and needle adapter (sports balls and inflatables). This makes it suitable for a wide range of inflation tasks beyond automotive use.
