Rechargeable electric inflation eliminates the CO2 cartridge calculation from your ride planning. The Eflator Mini from Fix Manufacturing delivers 120 psi maximum pressure from a 500mAh lithium-ion battery that handles four mountain bike tires from flat to 25 psi or seven gravel tires to 35 psi on a single charge. At 108 grams, the pump weighs less than carrying two 16-gram cartridges with a threaded chuck, and you're not throwing metal cartridges in the trash after every flat. The 72mm by 45mm by 32mm dimensions fit in a jersey pocket without the bulk of a frame pump.

Dual LCD displays show real-time pressure readings and battery status while you're inflating. You can set a target pressure and let the pump run automatically until it hits the number, or you can monitor the gauge and stop manually if you're dialing in pressure for changing terrain. The auto-stop function matters when you're topping off a tubeless setup before a ride and don't want to overshoot your target by five psi. Road tires inflate to 80 psi in 60 to 90 seconds, and the pump handles everything from narrow 25mm road rubber to wide 2.5-inch mountain bike tires without changing any settings beyond your pressure target.

The valve interface uses a push-to-seal connection rather than a threaded chuck. You screw the appropriate adapter onto your valve first, then push the pump head onto the adapter and hold it in place during inflation. This means you're maintaining pressure contact manually rather than letting a threaded connection lock on, which requires paying attention during the inflation cycle. The system works with both Presta and Schrader valves using the included adapters, and there's a ball inflation needle if you need to top off a basketball or soccer ball between rides.... Read More
