SLIM K2 Intelligent Charger

I own four battery chargers atm. Three are Nightcores and one is this particular E fest.Obviously, the Nightcore chargers are built so much better and offer a better variety of batteries that can be charged. I did, however, have an issue with the Nightcore new i2 charger in which it only would charge one battery at a time. That is why I grabbed this E fest because I didn’t want to lug around a huge charger with me. This is actually the second E Fest charger I have owned. The first one lasted me about two years and finally the micro USB port broke..I needed a quick replacement and was going to get another Nightcore, but decided to look into this oneApparently, I have issues with dual battery chargers. All of the other ones I have are four batteries and they have never had issues.The first Efest was just like this one but had a micro USB and took almost 5 hours to charge two 18650 batteries- but I really liked the portability of this charger-so I thought I would just grab a new one since it was really cheap. I didn’t even realize that they had upgraded from micro USB to USB-C .What a difference with the USB-C. It doesn’t charge insanely fast, but in about two -three hours I can get my batteries fully charged. No, it isn’t the fanciest charger. It is super basic and I wouldn’t suggest it if you use it for charging 18650 vape batteries that would go in a mech mod (i’m just OCD about mechanicals, which batteries I use in them, and how they are charged).Unfortunately, you can’t put rechargeable AA or AAA rechargeable batteries in it but 18650s, 18350s, 21700s, and 20700s all can be charged with this (along with a few other types). I will also add that if I plug this straight into a power strip that has USB power inputs it seems to charge faster than an adapter. It could just be me thinking that it charges faster directly in a usb port,It isn’t like an iPhone or other device that can be charged faster with a more powerful USB adapter but seems to charge even faster direct.It’s really about the portability for me with this particular charger.It isn’t fancy. It doesn’t show you your battery levels. It basically turns blue when batteries are fully charged.I will be totally honest- it is a little cheaply made. It works great as a back up and portable charger. It works great if you need a tiny charger-it does the trick. And for such a low price I obviously liked it enough to purchase it a second time. It isn’t my main charger but it’s definitely my work charger.

A few years ago I bought this charger to recharge my batteries I use for vaping. The older one had the Micro USB which I had to find the cable for every time. Fast forward and I thought I lost the old one and bout the new one and I didn't realize that it now has USB-C which saves the headache of finding the correct cable. I does the job and still satisfied.

Works perfectly.

After 3 months this one still works unlike their 4 bay intelligent unit I purchased at the same time that has completely failed already.

Simple to operate, lights are white when charging and blue when finished. Love that it is usb-c and small enough to toss in a bag to travel.

Reduced size & weight. Convenient for travel.Basic operation to cover most recharge needs.Fits multiple sizes of batteries & run various checks to protect batteries.

Charged fine but noticed that one of the bays must have a tighter spring as it put a small divot/dent in the negative of 2 different batteries before I noticed. 1 star.

Replaced a duplicate that finally (after several years of daily use) wouldn't charge both sides completely. I use this to charge my e-gig batteries. Works great! This model doesn't have all the fancy gismos and lights and readouts, but guess what? It also doesn't have a ridiculously high price tag for those non-essentials.
