I use a cordless air compressor with needle attachment to inflate my yoga ball.
Here's the device I used which was purchased on Amazon:
NUSTE Tire Inflator Portable Air Compressor, 150PSI Cordless Air Pump with 15000 mAh Powerful Battery, 3X Faster Inflation Electric Tire Pump with LED Light for Car, Bike, Motorcycle, Ball
𝟭𝟮𝗩 𝗖𝗼𝗿𝗱𝗹𝗲𝘀𝘀 𝗧𝗶𝗿𝗲 𝗜𝗻𝗳𝗹𝗮𝘁𝗼𝗿 - NUSTE tire inflator can provide 150 PSI maximum pressure and 35 L/Min airflow, which inflates the car tire in daily situations 30-36PSI within 30s or only consumes 3mins to completely inflate the car tires(195/55/R15) from 0 to 36PSI, 2-3 times faster than other air pump. It's perfect for inflating cars, motorcycles, bikes, balls, and other inflatables.
