Stackable SRAM Battery Charger | Charge All Your eTap Batteries at Once

Stack and charge multiple SRAM eTap or AXS batteries simultaneously | LED battery percentage display

Magnetic side connectors | Expandable to any number of units | Powered by USB 5V 2A (recommended) or powerbank

If you race or travel with a full AXS setup, you already know the battery juggle.

A road bike typically needs two batteries minimum: rear derailleur and front derailleur, plus a spare.

An MTB build with a RockShox AXS dropper and fork adds up to four. That's a lot of batteries to track, and a lot of chargers to carry.

Features

Magnetic Stacking System

Each charger unit has magnetic contact points on the side that connect to the next unit in the stack.

Power passes through the chain from a single USB input, so you only need one cable and one adapter regardless of how many units you're running.

LED Battery Percentage Display

Each unit has its own LED display showing the charge level of the battery sitting in it.

At a glance, you can see which batteries are done, which are still charging, and whether everything will be ready in time. Far more useful than a simple charging light.

No more midnight battery checks!

Standard USB Power Input

Powered by any 5V 2A USB adapter (recommended).

Works with standard powerbanks too, which makes it genuinely useful for travel, remote race venues, or anywhere wall sockets are scarce.

Note that quick charge adapters using proprietary fast charge protocols may not be compatible, hence the standard 5V 2A output recommendation.

Compact and Portable

Individual units are small and light enough to pack without thinking about it.
