A spare or replacement charging base for SRAM's clip-in eTap and AXS batteries. Snap the battery in, plug the base into a USB power source with a USB-C cable, and a full charge takes up to about an hour.

Highlights

  • USB-C charger base (A2) for SRAM eTap and AXS batteries
  • Full charge in about 60 minutes with a suitable power source
  • LED shows power supply, charging and charge complete
  • Push-button battery release
  • Charger only: USB-C cable, wall adaptor and battery not included

Power source

SRAM recommends a USB 3.0 or later port, or a USB wall adaptor supplying at least 1A at 5V. Older or weaker ports still charge, just more slowly.

Reading the lights

Solid blue means the charger has enough power and flashing blue means the supply is weak. Amber shows the battery is charging, green that it's full, and red flags an error.

Compatibility and fit

For SRAM's removable eTap and AXS rechargeable batteries, like the one on an AXS rear derailleur. You'll need your own USB-C cable. Refit the battery cover whenever the battery is off the charger or bike.
