Digital Display Handheld Wireless Air Pump with Dual Power Supply for Vehicle Tyre Inflation

This portable inflation device combines precise digital pressure measurement with cord-free operation for maintaining optimal tyre pressure in cars, bicycles, electric vehicles, and sports equipment. With dual power options from internal lithium batteries or vehicle cigarette lighter connection, it provides reliable inflation capability without requiring mains electricity. The compact 49×87×137mm design houses an 80W motor capable of generating 150PSI maximum pressure, while the digital display shows real-time pressure readings with ±1.5PSI accuracy for controlled inflation.

Technical Specifications and Performance

The air pump delivers measurable inflation performance through carefully engineered components designed for portable use. Operating at 7.4V with a working current under 7A, it balances power output with battery efficiency.

Motor and Inflation Capability

An 80W motor drives a 19mm diameter piston to generate airflow rated at 35 litres per minute. This combination provides sufficient pressure for car tyres while maintaining portability, with the unit capable of reaching 150PSI maximum pressure. The 200mm air hose includes standard fittings compatible with most valve types when used with the appropriate nozzle from the four included varieties.

Power System and Operation

Two 2000mAh lithium batteries provide approximately 40 minutes of continuous operation per full charge, with recharging taking 2-3 hours via the included USB cable. Alternatively, the cigarette lighter connection cable allows unlimited operation when the vehicle engine is running. The dual power approach ensures the pump remains functional whether used remotely or with vehicle power available.

Measurement and Control Features

A digital pressure display shows real-time readings during inflation, with accuracy maintained within ±1.5PSI across the measurement range. This allows precise pressure setting without manual gauge checking. The system operates at less than 85dB noise level during normal use, reducing disturbance during inflation tasks.

Practical Features and Applications

Beyond basic inflation, several integrated features enhance the pump's utility in various scenarios from routine maintenance to emergency situations.

Lighting and Safety Functions

A built-in LED light provides 20LM luminous flux for illumination during low-light inflation tasks. The same light module includes an SOS rescue warning function that can alert other road users during breakdown situations. This dual-purpose lighting serves both practical workspace illumination and emergency signalling needs.

Vehicle and Equipment Compatibility

The pump's pressure range and airflow rate suit multiple inflation applications beyond car tyres. Basketballs, bicycle tyres, and electric vehicle tyres all fall within its operational scope when used with appropriate nozzles. The four included nozzle types cover common valve fittings found on these various inflatables.

Portable Design and Handling

Constructed from ABS plastic and metal components, the pump measures 90×156mm in its main body dimensions. This compact form factor, combined with wireless operation, allows easy storage in vehicle compartments and straightforward transport to inflation sites. The design prioritises functionality while maintaining manageable size and weight for handheld use.

Usage Considerations and Maintenance

Proper operation and care ensure reliable performance throughout the pump's service life while maximising battery longevity.

Power Management and Charging

For extended inflation sessions, connecting to the vehicle's cigarette lighter socket provides continuous power without draining internal batteries. When using battery power alone, the 40-minute runtime allows inflation of multiple tyres before requiring recharge. The USB charging system operates at 5V, compatible with standard phone chargers or vehicle USB ports.

Nozzle Selection and Connection

The four included air nozzles cover common valve types for vehicles, bicycles, and sports equipment. Selecting the correct nozzle ensures proper seal and efficient inflation. The 200mm hose length provides sufficient reach for most tyre valve locations while maintaining compact storage.

Operating Limits and Care

The pump's 150PSI maximum pressure should not be exceeded during operation. Allowing cooling periods between extended inflation sessions helps maintain motor performance. The included fuse protects the electrical system from voltage irregularities when using vehicle power connections.
