Fenix are-A2 Smart Battery Charger for 21700/18650/16340 BBX5 Battery Carry case

Works great! Two different batteries charging at same time tons safety features but don’t charge unsupervised just in case. Three different ways to monitor charging nice lcd screen Worth every penny

I bought this when I found my Nitecore charger that I'd bought a number of years ago for my 18560 batteries wouldn't fit the 21700 batteries for my newest Fenix flashlight. It's nice, has essentially the same information the the Nitecore had but it seems to charge faster. I've got several flashlights but have settled on Fenix for build quality and reliability. I've still go and use a lot a Fenix TK15 that i bought in 2008. I'm hoping the Fenix build quality rubs off on this charger.

I’ve been using this charger for a year and it’s still great. No issues whatsoever.

This charger will not warm up 18650 batteries. I like the voltage, current, and charge timer display. Nice blue display with white digit segments. Easy to read and operate. Lithium-ion batteries should be cool the touch while charging and after charging. Safe and effective charger.

The Charger arrived as promised. I had a Battery that needed charging, plugged in the new charger and within a short time ,it was full. It has 2 bins ,so I could charge 2 batts if needed. I have to say, Fenix makes quality products. I have a Fenix Mdl UC 30, I received from my' Bride', about 5 years ago.. I LOVE IT!! It came with a electric charger but recently it was not working. This charger is plugged into the wall socket & you're in business within a reasonable time. Thank you and my Fenix Flashlight #UC 30 thanks you for the rapid delivery.

It really is a quality charger with one amp per channel, so it may take longer to charge your beefier batteries, but it will definitely do it safely. Removing it from the packaging is about the only unsafe thing about this charger. It's like the blow molding was still hot when they inserted it into the packaging, and the plastic cooled around the charger. Trying to peel it out of the plastic slashed my fingers pretty badly, but that's what I get for using scissors and not a box cutter. (That, or I was just an unlucky purchaser lol)

It works great. Easy to use

I purchased this charger for mainly 18650 and 21700 batteries. I needed something that was "smart" and properly backed off charging once the cell filled, and also had a decent charge rate. This fulfilled both needs. The current indicator is bright and easy to read versus similar devices (I have at least 5 other types). Cells can be charged in tandem or individually. Different types of cells can be charged at the same time also (tried with 18650 and 21700 cells). About the only issue was that it was packaged in this "survive the apocalypse" plastic that had to be cut away. I.e., once I'd removed the backing the device was still locked in place with weapons grade plastic. Ok, I'm exaggerating a bit but it was annoying.
