Bosch PAO 18V P4A Cordless Air Compressor Pump
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).

Battery AH Explained
The best way to describe battery amp hour is that this is effectively the size of your fuel tank, the more amp hours your battery has then the longer the battery will last between charges. More amp hours does not increase the power of a given tool.
Battery Voltage Explained
A tool with a higher voltage than another is a bit like choosing an engine in a car, the higher voltage will generally mean higher power & performance. As with cars though a bigger engine does not always translate to better performance so it is important to compare the specifications of tools at different voltages between different manufacturers.
Bosch PowerForAll
The Bosch PowerForAll Tool range is a range of tools you can buy knowing that batteries are compatible with all tools in the range providing they are of the same voltage. eg 18v fits 18v, 12v (10.8v) fits 12v (10.8v) etc. Please also note that 10.8v is compatible with 12v & vice versa as it is just a name change. Indego Lawnmowers also use the PowerForAll 18v battery but require a cover plate to be removed if changing.
PowerForAll has many advantages not least the fact that once you have a tool with a few batteries then there is no need to buy the more expensive versions with battery & charger, you can just go ahead & buy the much cheaper no battery versions!
So remember PowerForAll signifies complete battery compatibility throughout the range. There is however, one caveat to this, some of the very first older chargers will not charge the very latest batteries & a battery charger upgrade will be required if you have a first generation charger. All batteries fit all tools however.
As of 2021 Bosch has licensed PowerForAll to other manufacturers whereby batteries between these manufacturers will be interchangeable.
Important
You cannot use Bosch Pro (Blue) batteries in either 12v or 18v DIY (Green) products.
