SRAM AXS and eTap Battery Charger 4-Port USB-C, No Cord, A2

This 4-port USB-C battery charger from SRAM, the AXS and eTap Battery Charger (EP-EAC-BC4P, A2), keeps AXS-equipped riders running across an entire wireless setup. Four ports charge up to four batteries at once, so a rider can top off the Eagle AXS derailleur, RockShox Reverb AXS post, and Flight Attendant packs together instead of cycling through a single dock.

A full four-battery charge takes about 60 minutes, with quick-charge reaching 75 percent sooner, and LED indicators report charge status and power draw at a glance. The charger mounts on a bench or wall and works with SRAM eTap AXS, Eagle AXS, RockShox Reverb AXS, and Flight Attendant batteries interchangeably.

Note the A2 variant ships without a USB-C cord, and batteries are not included. For riders committed to a full SRAM AXS ecosystem, one dock covers every battery in the garage.
