TOPUMP TB2 PRO Mini Portable Electric Pump | Cordless Bike Tire Inflator 120PSI

This mini electric pump from TOPUMP is built to keep you moving. The TB2 PRO is a cordless tire inflator that fits in your pocket or bike bag, yet delivers up to 120 PSI of pressure. With a built-in 450mAh battery and a clear digital screen, it takes the guesswork out of inflating your bike tires on the go.

Forget hunting for a gas station or struggling with a hand pump. This compact device uses a Type-C interface for fast charging, powering up in about 30 minutes.

When it reaches the target, it shuts off automatically, preventing over-inflation.

Whether you ride a road bike with 700*25C tires or need to top off a mountain bike tire, the TB2 PRO handles the job with minimal effort. The auto shut-off feature and memory function make it a smart, hassle-free tool for regular maintenance or emergency roadside use.
