SRAM eTAP/AXS Four Battery Charger Description: The eTAP/AXS Four Battery Charger allows for very rapid charging of up to four AXS batteries in about the same time that a single battery charger would take to charge a single battery. The charging process is quick and painless; just flip the tool-free battery latch up and slide the batteries out of the derailleur, seatpost, and/or suspension part. Then snap the batteries into the SRAM eTAP/AXS Four Battery Charger and connect the charger to any power source via an USB-C charging cable (USB-C charging cable and wall adapters are not included). When the LED indicators tell you the battery is charged, remove the batteries from the charger and re-install them, make sure the components are sync'd to the controllers, and then get out and have fun on the bike! Note: USB-C style charger cable/cord and/or power supply adapters are not included with this charger and are available separately.
