Fenix ARE-A4

"IWOW!! This is the very best battery charger I have ever owned I have 2 I may get 2 more I have changed up AA, AAA, 18650, 21700 5,000 mah batteries to 21700 6,000 mah with a tight fit no worries this charger does it all with no issues I have been a loyal Fenix flashlight costumer for more then 30 years my Sister in law has my first Fenix TK 35 with the original 18650 Lithium ion batteries that have been charged up over 2500 times land still hold a charge. I do not know it is even possible but I have seen it in action she still uses the flashlight to this very day 02, of May 2026 these ARE A-4 chargers are amazing I have been told not to charge up my 21700 6,000 mah BATTERIES IN THIS CHARGER, I have about 60 times it does get a bit warm. My batteries are still working just fine. I have purchased aboutb100 flashlights batteries and other equipment from Fenix and McGuckens hardware store in Boulder Colorado. i now am way down as far south east as one can get here in Florida. Thank you 🙏 At Fenix, Chrispen G. Florida"

Fourth time a charm

"This is the fourth charger I have ordered. The other were nasty. I have five fenix lights. They are awesome. This charger is the only one that is functional. It is doing a nice job for now. 🤞"

not friendly anymore

"Fenix seems to have changed from a friendly web site to one that adds extra goodies on the order to double the cost. Trying to order a $40 charger results in a cost of over $100 and no idea of what I might be ordering. I now have 9 batterys and no way to charge them."

Awesome Charger

"I've owned one of these chargers for several years and have never had any issues whatsoever. I just purchased this one due to the amount of batteries I charge. My older one is still going strong. I only wish you could change the ARB-L1-2600 batteries. Other than that it's a great little charger!"
