    The battery charger is awesomely a fast charger for my pd36r flashlight, which unfortunately does not work anymore. But I could still use the battery for my other flashlight.

      Warranty will be reaching out to you on that PD36R that isn’t working to see what’s going on.

    This is my third one, lost the last one to my son who uses it daily to charge his gaming batteries. Excellent product once again as always! Thanks

    It’s Fenix, so I felt confident buying it. I inspect homes and would kill a lot of batteries if not for rechargeables. The Fenix four-battery dock recharger is great for recharging simultaneously. I highly recommend it. However, with everything electronic, you must take care of it!

    Great charger, fits all my batteries and I love seeing the status.

    I bought this charger because I needed something to replace my aging and extremely slow charger that I used to charge my 16340’s and my eneloops, however I also wanted something that was capable of charging my new Fenix 21700 batteries. This charger met that criteria, and has been performing very well. The readout is informative, yet simple to read, use and understand. It is well-built (like everything Fenix I have owned) and is a solid performer at a great price. As someone who charges various battery formats and has owned multiple battery chargers and charger brands, I highly recommend this charger!

    My one month review of the Fenix ARE-A4 battery charger. I was looking for a battery charger that supported protected button-topped 21700 Li-Ion rechargeable batteries, properly charged AA/AAA Ni-MH rechargeable batteries, and ran off AC power for simplicity. There aren’t many options to choose from that cover all of my needs and Fenix is a trusted brand. I have personally used it to charge AA/AAA Ni-MH rechargeable batteries, both regular 18650 and protected button-topped 14500, 18650, and 21700 Li-Ion rechargeable batteries multiple times without noticing any quirks. The charger correctly identified all battery types and charged them to the proper voltage without getting too warm.

    We have several Fenix products and the rechargeable batteries are only part of their attraction. It’s good that so many use the same charger!

  8. James M. (verified owner)

    I needed a charger for 21700 batteries, and not many are out there that can take the longer protected batteries. I use this charger for my 21700 and 18650 batteries, and so far works great. I would expect Fenix to only sell quality chargers.

    Love it to death

  10. David (verified owner)

    Great products, great prices. I bought 2 of these chargers and they worked flawlessly for the 8 plus hours I used them to charge all my batteries. Thanks again! Looking forward to future purchases from this company!

    Great product. I love all Fenix products.

  15. Vaughn (verified owner)

    I have one of the older 4 battery chargers an this one will charge the new 21700 batteries, plus all the other 18650 series to. So now I have two great chargers to help keep my batteries charged. Thank you Fenix for the great products, flashlights, batteries. An chargers to help light up my way.

    I tried lots of simple charging stations but this one is a proper upgrade. I love the digital readout showing the status of the battery so if needed, you can use it as a battery tester before going on an adventure. It even can charge 4 of the new large 5000mah batteries.

    Shipping was faster than anticipated. I received a 20 % discount because it was my first order which made it cheaper than Amazon. Very satisfied with the charger especially all the stats it provides while charging.
