    Super Charger. I love this thing. It beats the old one I had. Very quick shipping and friendly customer service from Eciggity. Still my #1 place to shop after all the others failed.

    AWESOME charger!

    This thing is great - being able to toggle between .5amp and 2amp charging is like a miracle. When you need a quick charge, it'll do 2x 18650's in (what feels like) no time on 2 amps. Easy to read display, and the portability make it an easy choice. I bought this to upgrade from my NiteCore D2, as I was needing more capacity - It's my favorite charger so far.

    This charger is very good

    I have charged mostly three married batteries at a time on this charger at the .5 setting. Even at the lowest setting, they charge quite quickly, and the charger seems to prioritize the battery with the lowest charge. All the batteries reach a full charge at approximately the same time, and I think that's awesome.

    Works amazingly

    Posted by Unknown on Jan 04, 2016

    To start I have to say I've had this product for only a couple weeks... However I have ran two sets of 3 18650 batteries thru it charging atleast one of the sets each day... I have used it on the 1amp and 0.5amp setting.. The charger works great it is a beast... Far quicker than my previous chargers (Nicore 2 & 4 and trustfire)... The screen is simple and clear... The reading it shows I feel are accurate based on measuring the batteries with a volt meter prior to putting them on the charger and after... It is really nice to have the option on charge level... And to have the included car adapter (haven't used that yet)... And it does not have that high pitched ringing sound that some other chargers have Over all I would highly recommend this charger... It has been a great upgrade from my Nicore... I'm very happy
