Running AXS across multiple bikes means juggling a pile of batteries, and a single-port charger turns that into a slow, one-at-a-time chore. The SRAM AXS 4-Port Battery Base Charger solves that bottleneck by taking four batteries at once. When you need a lot of AXS batteries charged in a hurry, this is the tool you want, and it fills all four in the same time a single-port charger handles one.

Charge time is 60 minutes for a full set of four batteries, and faster if you're only topping off one or two. There's a fast-charging feature that gets batteries to 75% quickly, so if you're heading out the door and forgot to plug in the night before, you can still grab a nearly full battery in a fraction of the time. LED lights on the base show charge status and power draw for each port, so a quick glance tells you which batteries are ready to ride and which still need time.

This is a USB-C charger, and the cord is not included with this version, so you'll need your own USB-C cable and a power source to run it. The base works on a benchtop or mounts to a wall, which makes it easy to set up a dedicated charging station in the garage or workshop. It charges the batteries used on SRAM eTap AXS derailleurs, Eagle AXS derailleurs, RockShox Reverb AXS seatposts, and Flight Attendant suspension, so one charger covers the full AXS ecosystem across road, mountain, and gravel setups.
