FAQ for Operating the ASTRONAVT Car Air Compressor
Power Supply and Connection
What power source does the ASTRONAVT car compressor use and how do I connect it to a vehicle?
From a 12 V vehicle electrical system via the cigarette-lighter socket. Connection to the battery is possible through a cigarette-lighter-socket adapter with crocodile clips; USB is not supported; operation from 220 V is possible only via a 220>12 V adapter.
Can the compressor be used with a 24 V on-board network or via a USB port?
Operation from 24 V is not recommended: the device is designed for a 12 V on-board network.
Can the inflator be connected directly to the car battery?
Yes, via a separate cigarette-lighter-socket adapter with crocodile clips. Direct connection to the terminals without a fuse is not recommended.
.Is power from a 220 V outlet allowed via an adapter?
Yes, when using a 220>12 V AC adapter with a cigarette-lighter receptacle and a current rating of at least 10 A.
Does a built-in battery exist and does the device need charging?
This wired version does not include a built-in battery and does not require charging.
Is it permissible to connect directly to battery terminals?
Permissible only via a cigarette-lighter-socket adapter with an integrated fuse.
Can the compressor operate from a 220 V outlet?
Yes, provided a 220>12 V adapter with a current rating of at least 10 A is available.
How do I replace the fuse in the cigarette-lighter plug?
Unscrew the plug cap, replace the fuse with an equivalent 10 A fuse, and reinstall the cap.
Controls and Indication
Is there an auto-stop function and can I operate without it? (ASTRONAVT car compressor)
Auto-stop is available: the compressor stops when the set pressure is reached; auto-start when pressure drops is not supported. The auto-stop function can be disabled for manual operation.
How do I switch on the light or work lamp on the compressor housing?
The light is switched on by a dedicated button with a lamp icon. The LED is used to illuminate the wheel area.
How does auto-stop operate and can I inflate manually?
When the target pressure is reached, the compressor switches off automatically. The function can be disabled and operation controlled manually.
What modes are shown on the display?
The display shows the selected units of measurement, current and target pressure, and a power indicator.
Is the display backlit?
Yes, the digital display has a soft backlight for working in the dark.
.Operation and Performance
Is there an auto-stop function and can I operate without it? (ASTRONAVT car compressor)
Auto-stop is available: the compressor stops when the set pressure is reached; auto-start when pressure drops is not supported. The auto-stop function can be disabled for manual operation.
How do I set a target pressure for automatic shut-off?
Select the units of measurement, set the required value using the “+”/“?” buttons, then start inflation. The compressor will stop at the set value.
Does the device display the current pressure before inflation begins?
Yes, the digital gauge displays tire pressure immediately after connecting to the valve with power applied.
What is the minimum pressure threshold that can be set?
The minimum setpoint is about 0.2 bar (?3 PSI); convenient for bicycle tires and low-pressure accessories.
What are the maximum pressure and performance ratings of the ASTRONAVT car compressor?
ASTRONAVT compressor: Maximum working pressure up to 10 atm (?150 PSI). Throughput about 35 L/min (for the ~120 W version).
Is it possible to inflate a SUP board, PVC boat, air mattresses, and sports accessories?
Suitable for passenger-car tires, crossovers, R18–R20 and above at standard pressures of 2.0–3.0 bar. For SUP boards and PVC boats, operation via an adapter is possible, but inflation will take longer; the device does not support continuous blower mode.
How does auto-stop operate and can I inflate manually?
When the target pressure is reached, the compressor switches off automatically. The function can be disabled and operation controlled manually.
Is the compressor suitable for inflating boats or mattresses?
Yes, but the inflation rate is lower than that of specialized pumps. No reverse air discharge (deflation) function is provided.
How can I read the current pressure without inflating?
After attaching the hose to the valve and powering on, the display shows the current pressure.
How will I know that the target pressure has been reached?
The compressor stops automatically, and the display shows the final pressure value.
Can the pressure be adjusted while operating?
Yes, you can change the set value using the “+/?” buttons, but to correct it properly you should stop inflation first.
What is the inflation time for a passenger-car tire?
On average, 3–5 minutes at 2.2–2.5 bar.
What should I do if the compressor fails to build pressure?
Check for air leaks, verify correct chuck fixation, and ensure the hose is undamaged.
Can I use the compressor without setting a target pressure?
Yes, simply switch on the power — the device will operate until manually switched off.
May I hold the compressor in my hands during operation?
Not recommended: the housing heats up and vibrates. Place it on a flat surface.
.Temperature and Storage
What fuse and current draw does the compressor have?
ASTRONAVT compressor: Power is protected by a standard 10 A fuse. It is recommended to start the compressor with the engine running to avoid fuse burnout and voltage drop.
At what temperatures can the ASTRONAVT car compressor be used and stored?
ASTRONAVT compressor: Practical operating range is approximately ?25 to +45 °C; short-term storage in the trunk in winter and summer is acceptable. In severe frost, warm the device in the cabin before prolonged operation.
Can the compressor be stored in the trunk during winter?
Operating temperatures are ?25 to +45 °C. In severe frost, pre-warm the device.
How do I replace the fuse in the cigarette-lighter plug?
Unscrew the plug cap, replace the fuse with an equivalent 10 A fuse, and reinstall the cap.
Can the compressor be stored vertically?
Yes, the storage orientation is not critical; avoid moisture and impacts.
Can the compressor be used in sub-zero temperatures?
Yes, but below ?20 °C it is advisable to warm the housing before start-up.

Can the compressor be used to inflate balls?
Yes, using a needle adapter included in the kit. Pressure is regulated manually.
Can the compressor be used for R20 and larger tires?
Yes, but inflation time will increase. For truck tires with a large volume, a professional model is recommended.
.Maintenance and Troubleshooting
What should I do if the compressor does not switch on?
Check the 10 A fuse, the condition of the cigarette-lighter socket, and the ground contact. Make sure the vehicle engine is running.
How should I clean the housing after use?
Wipe the housing with a dry or slightly damp cloth, avoiding water ingress into the ventilation openings.
May I disassemble the compressor for cleaning?
Self-disassembly is not recommended — seals may be damaged and the warranty voided.
Can the compressor automatically bleed an over-inflated tire?
No automatic pressure relief is provided; deflation is performed manually via the valve.
What is the accuracy of the built-in gauge and in which units does it operate?
Typical indication error is about ±0.1 Bar (±2%). For critical applications, verification with a reference gauge is advisable. The display toggles between BAR, PSI, and kg/cm² (R/Unit button). It shows current pressure before inflation starts.
Piston and motor: what materials are used and what type is applied?
The piston group is composite: wear-resistant plastic plus metal elements; the motor is brushed.
Can the compressor be used in rain or damp conditions?
The housing is not moisture-proof; avoid operation in rain or snow. Brief use under a shelter is permissible.
How can I confirm that the compressor is powered and running?
When power is applied, the display lights up and the motor sound is audible. Pressure on the screen rises during inflation.
Does the compressor heat up during prolonged operation?
Yes, the housing and hose may heat up — this is normal. After 10–15 minutes of operation, take a pause to cool down.
What is the noise level of the compressor?
Average noise level is about 75–80 dB, comparable to a typical automotive inflator.
Why does the compressor vibrate during operation?
Vibration is inherent to piston operation. Place the unit on a flat surface.
Can the compressor be used with the engine off?
Briefly, yes, but it is preferable to operate with the engine running to avoid battery discharge.
Why does the compressor switch off by itself?
Either overheat protection has been triggered or auto-stop has activated upon reaching the set pressure.
Can balloons or inflatable toys be inflated with the compressor?
Yes, using suitable adapters and manual pressure control.
