Features and benefits

Instructions for use
Step 1: Connect the inlet of the tire pressure gauge to an air compressor or other compressed air source.
Step 2: Choose the unit you want (PSI, kPa, Bar, kg/cm² ) – whatever you need!
Step 3: Push the air outlet chuck directly onto the tire valve (so that there will be no air leakage).
Step 4: Once connected and pressure detected, it will automatically activate and display the actual tire pressure.
Step 5: Too low? Fully press the inflation valve to inflate. It’s too high? Press and hold the release valve to release air (refer to the display screen for reference).

Rechargeable Tire Inflator Gauge for a Compressed-Air Setup
The SEAPENG BW-L03C is a rechargeable digital tire inflator gauge for people who already use a compatible air compressor or compressed-air line in a garage, workshop, or vehicle-service setup. It is designed to check, inflate, and deflate tire pressure after its inlet is connected to that air source. The built-in 230mAh rechargeable battery supports the gauge’s rechargeable function; it does not replace the compressed-air supply needed to inflate a tire.
For day-to-day tire-pressure work, the listed range is 5–230 PSI (0.35–16 BAR). The gauge has a 24 in (60 cm) rubber air hose and shows pressure in four units, helping users read and adjust pressure without treating the tool as a standalone cordless air pump. Always follow the pressure on the vehicle tire-information label or owner’s manual.
Choose this tire inflator gauge when a compatible air source is already available and you need a rechargeable digital display for routine tire checks and inflation. For a broader fixed setup, explore garage tire inflation equipment. For business purchasing questions, request a wholesale quote.
Does the BW-L03C include an air compressor?
No. The BW-L03C is a tire inflator gauge that connects to a compatible air compressor or compressed-air source. It does not generate compressed air by itself.
What pressure range is listed for the BW-L03C?
The listed range is 5–230 PSI (0.35–16 BAR).
Can the BW-L03C inflate a tire without a compressed-air source?
No. The product instructions list connecting the inlet to an air compressor or other compressed-air source before use.
