Ensure optimal tire pressure before going on a ride with the Fumpa Battery-Powered Portable Bicycle Pump. Purposely engineered with cyclists in mind, this bicycle pump makes it easy to check pressure and quickly top up tires. Its unique compressor design compresses the air around you to fill your tires at an exceptional rate. Additionally, a single charge inflates six tires while charging the battery takes around two hours. The pump gets its power from a rechargeable lithium-polymer battery that you can conveniently charge using the included micro-USB cable. Simply plug the other end into your phone charger, PC or any USB charger. Featuring an adaptable push-on nozzle, the Fumpa is usable on both Presta and Schrader valves. Furthermore, the digital pressure gauge offers 3% accuracy so you can always hit the road with confidence.
