Category Compatible Vehicles / Equipment Motorcycles YAMAHA, HONDA, SUZUKI Sedans Nissan Sylphy, VW Lavida, Toyota Corolla, Honda Civic Bicycles Giant, Merida, Cannondale Not recommended for Mid-size SUVs → recommend S3/S5/X5 PRO. Full-size SUV / pickup trucks → recommend S5/S6/S7/X6 PRO. Full-charge tire capacity 3 tires (195/55R15, 0→35 PSI) Full-charge standby time 36 months (unit starts normally after 36 months storage)
Module 7: Technical Limitations & Notes
Condition Behavior Continuous inflation limit Aging test: unit connected to throttle valve at 35 PSI, discharged from full battery to empty — no thermal protection triggered, no fault reported Low battery performance (<20%) Inflation speed slightly reduced as battery voltage drops; max pressure unchanged, still reaches 150 PSI Simultaneous charging & inflating Not supported. Charging while inflating reduces voltage and lowers inflation efficiency. Extreme cold (<-10°C) After 2 hours at -10°C: inflation speed reduced due to lower battery discharge performance; unit starts and operates normally Long-term storage Recommended charge level: 100%. Max storage: 36 months. Top-up frequency: every 12 months.

Module 11: FAQ – Technical Reference
Question Answer Can S1 inflate a motorcycle tire? How long does it take? 700C×25C bicycle tire: 0 PSI → 100 PSI in 1 min 33 sec on a full charge; up to 9 top-ups per charge. What is the difference between S1 and S3? S1: 20 L/Min, 5200 mAh, 525 g, 94×76×40 mm — for Class A/B sedans. S3: 22 L/Min, 7800 mAh, 1050 g, 134×98×174 mm — for mid-size SUVs. Can S1 inflate 4 sedan tires continuously without stopping? Full charge capacity: 3 tires (195/55R15, 0→35 PSI). A 4th tire may not reach target pressure on a single charge. How many sedan tires can S1 inflate on a full charge (0→35 PSI)? 3 tires, tested on 195/55R15. What are the 4 modes and which vehicle types do they suit? Car: 35 PSI (sedans) | Bicycle: 22 PSI (bikes) | Basketball: 8 PSI (sports balls) | Custom: 30 PSI (any) Does S1 work normally at -10°C in winter? Yes. After 2 hours at -10°C, the unit starts and operates normally. Inflation speed is slightly reduced due to reduced battery discharge performance at low temperature.
