Fenix ARE-X2 Battery Charger - DISCONTINUED

Bought this to replace an old single-slot charger and the dual channels are a huge time-saver, letting me top off two different battery types at once without fiddling with settings. It's a shame it's discontinued because the auto-detection has been flawless so far with everything I've thrown at it.

I’ve been using it to charge both my AA and 18650 batteries at once, and it’s so convenient not having to swap them out one by one. The automatic mode selection means I just drop them in and walk away, and the charge indicator lights give me peace of mind that it’s working correctly.

The dual-channel setup is a lifesaver when I've got a mix of AA and AAA batteries lying around—just drop them in and it figures out the right mode on its own. Took a chance on this since it’s discontinued, but it’s been rock solid for a few months now.
