1. Quick Reference Table
| Problem | Likely Cause | Solution |
|---|---|---|
| Inflator won't turn on | Power button not held long enough | Long-press the power button (⏻) for 3 seconds to turn on the appliance |
| Inflator won't turn off | Power button pressed too briefly | Long-press the power button (⏻) for 3 seconds to turn the appliance off |
| Pressure display shows nothing / low battery symbol | Battery level too low | Charge before use via the Type-C port; ensure battery level is sufficient before inflating |
| Air leaking at the hose joint | Air hose not securely connected to the inflator or the item's valve | Ensure both ends of the air hose are tightly and securely connected before inflation |
| Wrong valve adapter fitting loosely | Incorrect adapter selected for the valve type | Use the correct adapter — Ball Needle, Presta Valve, Long Tapered, or Short Tapered nozzle — for the item being inflated |
| Hose or joint feels very hot after use | Normal heat build-up during/after inflation | Allow the hose and joint to cool before touching or unscrewing, to avoid burns |
| Inflation stopped but pressure is wrong for the item | Wrong inflation mode selected, or over-inflation risk | Check the required pressure for the item first (from its own instructions), then re-select the correct mode with "M" and re-set target pressure |
2. Pressure Unit Mismatch (BAR vs. PSI)
If the target/preset pressure looks far too high or too low — for example the inflator stops well short of what's needed, or seems to over-inflate — the unit may be set to the wrong scale (e.g. BAR selected when you meant PSI, or vice versa). The units are not interchangeable 1:1 (1 BAR ≈ 14.5 PSI).
Fix:
- Long-press "M" to cycle through the pressure units: PSI → BAR → KPA → KG/CM².
- Stop on the correct unit for your use case (PSI is standard for most car and bike tyres).
- Press "+" or "–" to re-enter your desired target pressure.
- Confirm the unit shown on the display before pressing the power button to start inflation.
3. Selecting the Wrong Inflation Mode
Vayu 2.0 has 4 built-in modes: Car, Motorcycle, Bicycle, and Balls. Inflating in the wrong mode can lead to under- or over-inflation relative to what you intended, especially for lower-pressure items like sports balls.
Fix:
- Press "M" (short press) to cycle through the inflation modes.
- Select the mode that matches what you're inflating.
- Use "+"/"–" to set the target pressure for that item before starting.
4. Over-Inflation Risk
The manual specifically warns to check the required pressure for the item before inflating, to prevent injuries caused by over-inflation. If unsure of the correct pressure:
- Check the sidewall of a tyre for its recommended PSI/BAR rating.
- Check the item's own packaging or instructions for balls and other inflatables.
- Use the Pressure Range guide: this device supports 3–150 PSI, with ± 1 PSI accuracy.
5. Battery & Charging Notes
- Ensure the battery level is sufficient before starting inflation — insufficient charge can cause the appliance to stop mid-task.
- Charge via the Type-C charging port (Input: 5V ⎓ 2A) using the supplied charging cable.
- Battery capacity is 6,000 mAh; monitor the Battery Level Indicator on the display.
