“Generally the peak charge and discharge current for LiIon are a bit high ….
for normal charging I will still prefer a charger with non-pulsing CC/CV charging.”
— HKJ’s latest review

Any hope if we wait that those problems will be improved?

Has the new charger ability to switch to 4.35V without opening it?

No, but if your are a bit proficient in using a screw-driver, it is just about a 4-minute job.

Is this Group buying valid for Italy too?

Now in new promo @ $35.49….

I have the 2.1 version and it is Awesome.

Very well built, I like that it will test capacity, shows voltage, charging ma, and will test mah capacity and more, and it treats your batteries right automatically !

I know more about all my batteries than I ever had before.

Charges/tests pretty much any rechargeable battery automatically.

My Opus charger revived 6 DEAD (2.0 volt) laptop 18650’s back to powerful batteries that now hold right at 4.2 volt and 2400 mah.

Those old “dead” 18650 batteries now power my XML-T6 501b like a champ !

Best 40.00 I ever spent.

That’s so true. The only skeptics left are those that have not not used this charger. I own an iCharger, a Pila IBC and Xtar VP2, and while also excellent chargers, they just can’t beat the versatility, feature and ease-to-use this 4-bay, multi-mode smart charger/discharger/analyzer.

You’ve got to use one to really know what you’re missing from the other chargers. Guaranteed!

I bought it for charging Li-ion batteries, but it charges any rechargeable battery I have put in it very well.

I have charged 1.2 volt Eneloops, Ni-cad , up to Li-on and they all charge excellent, voltage automatically sets and ramps down to full charge.

And if you want, you can charge/discharge/test all different types of batteries in slots independently, but at the same time.

My opinion, it may be better than sliced bread.

A real nice charger, I recommend it.

I would like to buy it because I just broke my ni-mh charger but I’m a little concerned about the fan’s noise.

Do the batteries get very warm if I unplug the fan’s connector? In both my li-on and ni-mh batteries never got very hot during their cycles.

While the version 2.0 and the earlier version of the 2.1 had indeed some fan noise complaints, the latter versions of the 2.1 and the latest 2.2 has many buyers comment about NOT having a loud noise coming from the fan. Of course, if you are coming from a fan-less charger, then you will find any fan-cooled charger….no matter how quiet it is.

And if youre proficient with a brick you dont need keys to get into your car either.

Some people have both battery types, its not convenient to get the screw drivers out to set the supposedly convenient charger to do the job.

Mine is pretty much silent, a tiny fan kicks on if you charge on all 4 slots at full power, pretty sweet !

Well, I’ve just bought it.
Let’s hope that it will be silent enough to to don’t bother my wife… :slight_smile:
Thanks to all for the informations

I just found some bugs in the v2.2 charger.

1. It seems to not recognise non-rechargeable AA batteries. It will attempt to charge them.

2. You can charge NiMH batteries at 1000mA! Mix some Li ions with the NiMHs and keep pressing “Slot” until all active channels are flashing. You can then set all active channels to charge at 1000mA, including the NiMH. I did not let the charging continue as I am afraid of killing my NiMH or causing then to explode.
