One of the Best Chargers out there!

I've tried a few different chargers and this one is still going strong after mo the of daily use. If you need to charge you vape batteries I would honestly suggest this one. It seems to be the best out of many I tried.

Dependable product

This charger works excellent. If repeated overcast days I will recharge my batteries in the garden . Takes about 4 hrs for complete charge

A bit flimsy, but gets the job done

Charges 18650 batteries, which is what I bought it for. It's incredibly light weight and small, much smaller than you realize. Other than that, the best thing I can say is, it works. It does its job. Not sure how long it's going to last, as it seems a bit cheaply-made, but we will see.

Garbage

First I'm going to suggest that when your see a review of someone using 18650 with mAh ratings above 3600, to disregard them. 18650 cannot hold anymore than 3600 mAH, thereby sleeping the reader that the reviewer isn't informed on the category of the product. Furthermore, this brand consistently makes claims that are untrue, as they have many products listed that involve 18650 batteries with impossible storage capacity. I would suspect that the components in this product aren't of the highest category, referring to another user's photo review of a popped capacitor, despite the sticker on the back includong the CE certificate (health, safety, environment). It is not UL certified, so the safety rating could be questionable. I would not recommend leaving the unit charging unattended/over night.When in use, the components in the top part of the charger are warm through the faux vented plastic, despite the batteries remaining at room temperature. There are two indicator lights for each charging bay. Red for charging and green for open or charged. That's it - no voltage readings, amount charged indicators, etc. The unit charges at the same rate as other 4.2V/.5A chargers that I have used previously.For what it is, it's a good price for a charger with perhaps questionable quality. Time will tell...UPDATE: Time did tell, only a few weeks though. It's a piece of garbage. Banks 1 & 2 are not reporting the battery status correctly. Banks 3 & 4 do not report the battery status accurately between the two occasionally. I don't like the fact that when a battery is left in one of the banks that they light up their corresponding indicator led. When the led indicates that it's charged, when in fact it is not fully charged, it stops charging. Putting the battery into a different bank or a completely different charger finishes the charging process. This seems pretty wasteful and serves no purpose other than to drain a battery.Skip this product, as it pretty much fails to do is only job, recharge batteries.

Perfect charger

This charger works great for my rechargeable batteries. I like that it shows info on the batteries that are in it and you can see when a battery is on its last leg. Charge time isn’t that long, although I usually put them in at night and take them out in the morning. I do have one of the leads that’s a little rough sliding it down, I believe something is wrong with the spring. If I slide it down with my hand, then I can put the battery in, but sliding it down with the battery is impossible. Usually I only charge 2 batteries at a time and the stuck bay is at the end, so not too much of a problem.
