This NNEOBA 120 PSI Cordless Air Inflator with Presta Schrader is the ultimate portable inflator for cyclists who need efficiency on the go. Built with a durable alloy body, it's designed to handle both Presta and Schrader valves, making it ideal for mountain, road, and hybrid bikes. Weighing just enough to be pocket-friendly yet powerful enough to fully inflate your tyres, this cordless pump is a must-have in every toolkit. To use on an empty inner tube, simply connect the pump to the valve and press start. For topping up a tyre that already contains air, activate the pump first, switch to inflation mode, then connect it to the valve. With smart functionality, high-pressure output, and rugged portability, it's your go-to for quick, reliable inflation – wherever the ride takes you.
