The Bosch PAO 18V P4A is a cordless air compressor designed for inflating tyres, sports equipment,...The Bosch PAO 18V P4A is a cordless air compressor designed for inflating tyres, sports equipment, and inflatables around the home. This versatile dual-function pump delivers professional-grade pressure capability up to 10.3 bar (150 psi), making it suitable for demanding inflation tasks from car and bicycle tyres to larger inflatables and sports balls. Smart control features put you firmly in command of inflation tasks. Pre-select your desired pressure value and the auto-stop function takes over, eliminating guesswork and preventing over-inflation. The memory function allows you to save up to three frequently used pressure settings for quick access next time. A clear digital LED display provides instant visibility of all relevant information during operation. The high-volume airflow of 400 litres per minute combined with the 700mm hose ensures fast inflation and deflation performance. Practical design touches include integrated storage compartments for the included high-pressure adapters, keeping everything organised and immediately accessible. The unit is compatible with the Bosch 18V POWER FOR ALL battery system, giving you access to a shared battery platform across multiple brands and tools. This bare unit is supplied with a tyre valve clip, French valve adapter, ball needle, and volume adapter. Battery and charger sold separately (minimum 1.5Ah battery recommended).

The Bosch PAO 18V is a cordless air compressor designed for DIY users needing to inflate tires, sports equipment, and inflatables at home. Its key benefit is the professional-grade pressure capability up to 10.3 bar (150 psi) combined with smart auto-stop and memory functions for precise, effortless inflation. A potential caveat is that it is sold as a bare unit, meaning the battery and charger must be purchased separately, with a minimum 1.5Ah battery recommended for optimal performance.

FAQs
What is the maximum pressure this compressor can achieve?
The Bosch PAO 18V can achieve a maximum pressure of 10.3 bar (150 psi).
Does this product come with a battery and charger?
No, this is a bare unit. The battery and charger are sold separately. A minimum 1.5Ah 18V POWER FOR ALL battery is recommended.
How do I save a frequently used pressure setting?
After inflating to your desired pressure, press and hold one of the memory function buttons (M1, M2, M3) on the unit until it beeps or confirms the setting is saved.
What is the difference between the 30 l/min and 400 l/min airflow specifications?
The 30 l/min refers to the pump's rated output for high-pressure tasks like tire inflation. The 400 l/min refers to the high-volume airflow mode, used for rapid inflation of items like inflatables or deflation.
Can I use this compressor to deflate items?
Yes, the unit features a deflation mode, activated by a specific button or function, which uses the airflow to remove air from items.
How long does a battery typically last?
Battery life varies depending on usage and battery capacity. A 2.0Ah battery can typically inflate several car tires or many sports balls on a single charge for moderate use.
What type of items can I inflate with the included adapters?
The included adapters are suitable for car tires (Schrader valve), French valves (Presta valve), sports balls (needle adapter), and general inflatables (volume adapter).
Troubleshooting
Unit does not power on.
Ensure the battery is fully charged and correctly inserted into the tool. Check that the battery contacts are clean.
Inflation is slow or not occurring.
Check that the hose connection is secure and that the adapter is properly seated. Ensure the air intake is not obstructed. Verify the selected pressure is not already met or exceeded.
Auto-stop function is not engaging.
Double-check that the target pressure has been correctly pre-selected on the digital display. Ensure the unit is functioning correctly; if issues persist, contact customer support.
Digital display is not showing information.
Try removing and reinserting the battery. If the display remains blank, there may be an internal issue; contact customer support.
Pros and Cons
Pros
Versatile inflation for a wide range of items.
Precise inflation control with auto-stop and memory functions.
Fast inflation and deflation speeds.
Clear digital display for easy monitoring.
Tool-free battery system compatibility.
Compact and portable design.
Cons
Battery and charger are sold separately.
Higher pressure applications might require a larger battery for extended use.
Bare tool means initial cost can be higher if you don't own compatible batteries.
Airflow of 30 l/min is for pump output, 400 l/min is for fast inflation/deflation, which can be confusing.
