GPUTEK Mini Electric Bike Pump — Portable Inflator for Presta & Schrader, 120 PSI, LED Gauge

The GPUTEK Mini Bike Pump Electric is a pocket-sized, rechargeable inflator that rapidly fills Presta and Schrader bicycle tires with precise, adjustable pressure up to 120 PSI.

Compact enough to carry on every ride, this mini electric pump combines a digital LED gauge, brushless motor speed, and interchangeable valve adapters to give cyclists a fast, accurate solution for on-the-go inflation and emergency repairs. Designed for road, gravel, folding, e-bike, and mountain bikes, it balances portable convenience with the power to restore tire pressure multiple times per charge.

How quickly will the GPUTEK inflator restore a flat tire?

The brushless motor delivers notably faster inflation than manual pumps. Typical performance examples include going from 0 to 100 PSI in about 80 seconds on a 70x23C tire, and topping from 80 to 100 PSI in roughly 40 seconds.

• Brushless motor for quicker fill times.
• Automatic inflation and pause functions free your hands.
• Noise and heat are normal during rapid operation.
• Great for rapid top-ups before a ride or mid-ride fixes.

What valve types and bikes does this pump support?

The unit ships with adapters for both Presta and Schrader valves and includes an air hose for flexible connection. It works with most bicycle types, from road and gravel bikes to e-bikes and fat-tire models.

• Includes Presta and Schrader adapters for easy switching.
• Hose attachment for convenient angled access to valves.
• Compatible with city bikes, MTB, folding bikes, and more.
• Small form factor fits into packs or pockets for rides.

How accurate is the pressure reading and how do I calibrate it?

A built-in digital LED gauge shows live tire pressure and allows adjustment between 2 and 120 PSI for tailored inflation. If you see any discrepancy, you can recalibrate the display by pressing and holding the "+" and "-" buttons together for three seconds.

• Professional LED gauge for real-time PSI monitoring.
• Adjustable target pressure from 2–120 PSI for precision.
• Simple calibration: hold + and - for 3 seconds.
• Useful for consistent pressures on road or gravel tires.

How many inflations can I expect from a single charge?

Despite its tiny footprint (2.81 x 1.77 x 1.25 inches, 0.23 lbs), the pump delivers repeated performance on a single battery cycle. Expect multiple full inflations of typical road tires and numerous top-ups before recharge is needed.

• Can inflate a 700x23 tire from 0–100 PSI 2–3 times per charge.
• From 80–100 PSI you may get up to nine top-ups on one charge.
• Small size makes it ideal as a daily-carry emergency tool.
• Lightweight—stows easily in a jersey pocket or saddle bag.

Who is this for? The GPUTEK Mini Electric Pump is aimed at cyclists who want a reliable, lightweight inflator that fits into pockets or small bags: road and gravel riders seeking accurate pressure control, commuters who need a fast emergency pump, and e-bike or folding-bike owners who value compact gear. It’s also a handy tool for recreational riders who prefer effortless inflation and clear digital readings without carrying bulkier equipment.
