This mass charger is fast, efficient and easy to use with the resultant fully-charged batteries being of a high standard charge extremely swiftly applied.

I'm no expert when it comes to battery chargers but I have owned a couple and this is without a doubt the nicest looking one I have owned and has a nice weight to it and the display is nice and easy to read. I have only had it two days and so far it charges fine with its supplied USB A to USB C cable but so far it doesn't seem to work with USB C to USB C cables which is a bit annoying as I got this to reduce clutter. It has a nice grading feature, which again is very easy to read which is great. From a novice's point of view, it charges my AA's fine and covers that side of things for me but I feel it wouldn't be a chore to increase my knowledge using this charger if I chose to.

I liked the thought of being able to charge 8 batteries at a time, but it cuts the charge current way down when doing this. But hey it can still do 8, just a little slow. I have used this to charge and test well over 150 18650 cells so far and it has helped me weed out the ones that were beyond use, plus told me when a few of them were faulty. Don't know how accurate the IR measurement is compared to a 4 wire tester, but I quite often get different IR readings on the same battery so if your IR readings are important to you then use a seperate meter. I'm guessing it's with +/- 10%The capacity function is good, but painfuly slow. It can only capacity test 4 cells at a time, but I knew this before buying. Just something to bare in mind if you have a lot of cells to go through. So far it's doing its job well enough and I would certainly recommend it for the price.

Absolutely great product. Great addition in everyone’s house. A bit expensive but hey feels sturdy and does the job. Nice display as well.

The charger will automatically work out the type of battery and therefore will charge it in the correct fashion for that battery.On the 1st 4 bays, there's a function to be able to see what the REAL capacity of your batteries are. Forget what's written on them, run it through this, and you get a real life reading.Spot on!

We have had this just under 10 weeks and it’s already faulty. It won’t change more than 4 batteries at a time without turning itself off and on in an endless loop. WASTE OF MONEY

The perfect device for my needs
