The 4-Port Battery Base Charger solves the workflow problem that AXS owners run into once they've built out a full electronic ecosystem — a road bike derailleur battery, a mountain bike derailleur battery, a Reverb AXS dropper battery, and maybe a spare or two, all needing to cycle through a single charging block. This USB-C powered charger fills four batteries in the same time as a single charger, with charge time even faster if only one or two batteries are being charged. If you've been rotating batteries through a single-port charger every time a bike needs a top-off, this is the upgrade that turns charging into a set-and-forget task.

The charger works with AXS batteries across the SRAM, eTap, and RockShox AXS component ecosystem , so the same station handles Red AXS, Force AXS, Rival AXS, XX SL Transmission, XX, X0, GX Eagle AXS derailleur batteries, and Reverb AXS dropper batteries. Each port operates independently, which means you can plug in one battery or four without any change to how the charger behaves. The fast charging feature gets the batteries to 75% extra quick, so if you're rushing out the door, it's got you covered.

LED indicators show charge status and power draw at a glance , so you can see which batteries are ready to install and which still need time without unplugging anything. The unit is designed to sit on a workbench or mount to a wall, which is genuinely useful in a home garage where counter space is already spoken for. Batteries are not included — this is the charging base only, so if you're new to AXS you'll need to source batteries separately.... Read More
