Portable rechargeable air pump LTC LXMP190 — 3.7V 5200mAh, 5A, 18.5W, USB‑C, 300 L/min, 4 nozzles, LCD display, carry case

The LTC LXMP190 is a compact portable rechargeable air pump with a 3.7V 5200mAh battery and a maximum output of 5A, delivering up to 18.5W of power and a peak flow rate of 300 L/min. Designed for on‑the‑go inflation, it includes an LCD display that shows pressure and operating status, USB‑C charging for convenient recharging, four interchangeable nozzles for different valve types, and a protective carry case for storage and transport.

Advantages

The pump combines a relatively high-capacity 5200mAh battery with a 5A output to support quick inflation cycles without needing mains power. Its LCD display provides clear readouts of pressure and operating status to help achieve accurate inflation. USB‑C charging ensures compatibility with common chargers and power banks, while the included set of four nozzles and a carry case make the unit versatile and easy to take on trips or store in a vehicle.

Suitable for

• Inflating car, motorcycle and bicycle tires (via compatible valve adapters)
• Filling sports balls such as footballs and basketballs
• Inflating air mattresses, sleeping pads and camping gear
• Inflating pool toys and small inflatables for leisure use

When it may not be suitable

The LTC LXMP190 is intended for portable and occasional use rather than continuous industrial operation. For inflating very large commercial inflatables or for continuous high-volume professional use, a higher‑capacity or mains-powered compressor may be more appropriate. The pump’s maximum pressure and runtime depend on the inflation target and ambient conditions; very high-pressure applications may require specialized equipment.

How to use

Charge the pump fully using the USB‑C port before first use. Select the appropriate nozzle for the valve you are inflating and attach it securely. Power on the unit and use the LCD display to set or monitor the target pressure if the model supports pressure presets; start inflation and monitor the display until the desired pressure is reached. After use, power off, remove the nozzle, and store the pump and accessories in the carry case. Follow any safety instructions in the supplied manual regarding continuous run time and cooling periods.

What to consider before purchase

• Required maximum pressure for your tyres or inflatables — ensure the pump meets that pressure need
• Expected frequency and duration of use — this unit is optimized for portable, occasional inflation
• Compatibility of included nozzles with the valves you use
• Availability of USB‑C charging sources for recharging on the go

Usage recommendations

For best results, fully charge the battery before heading out, check valve compatibility and clean valve interfaces to ensure a good seal, and allow cooling pauses during extended inflation sessions to avoid overheating. Store the pump in its carry case to protect the unit and accessories when not in use.
