Can it inflate car tires?

No. Its maximum pressure is 0.55 psi, far below the roughly 30 psi a car tire needs. It is made for air mattresses, floats and toys.

How long does one charge last?

The 2000 mAh battery fills a few small inflatables or one air mattress per charge. Large items or several mattresses will drain it, so bring a power bank for longer trips.

It charges over USB, so a phone charger, laptop or power bank works. A full charge takes a few hours.

Does it deflate as well as inflate?

Yes. It has an inflate and a deflate mode, which helps flatten mattresses and pack floats away.

What nozzles come with it?

It includes interchangeable nozzles for common valve sizes on mattresses, pool floats and beach toys. Check that your valve matches before relying on it.

Is it better than a hand pump?

It saves effort and is faster on large items, but a hand pump never runs out of battery and can reach higher pressure. For low-pressure inflatables, the USB200R is the easier choice.
