    Charged several batteries with this, I prefer it over the USB-topped batteries designated by the U-suffix sold by Fenix. It’s easy to understand and use and it charges all the latest style batteries along with some of my older-style ones.

    Genius design that serves dual purposes. I carried this charger and the ARB-L18-3500U rechargeable battery during a 100 mile mountain race. This eliminated the need to carry an additional power bank to charge my watch/phone since I would need a spare battery for the headlamp anyway – of course I was using a Fenix headlamp. Less gear to carry and I was a happy runner. Thank you Fenix!

    I think this charger does work and is not to blame for failing to charge one rechargeable battery that Fenix supplied with a PD25. The charger’s display is a nice feature.
