this is the safer and the best charger Review by Jean-Claude
Rating
This is the safest charger available due to the fact that the temperature is constantly controlled under each battery slot and also on the PCB. So even if the fan goes down, the charger will stop if overheated.
The Fan is not noisy at all, as written in other comments, and can run at different speed. On top, the fan only runs when higher current is selected on 4 batteries. For instance, charging 4 AA batteries at 300 ma will not heat enough to start the fan
It is the only one showing the real current on top of the selected current, which is the best way to control overcharging. It also stop exactly at maximum 4V2, which is not the case with some other charger i have tested.

Best charger for the money, but Loud fan (v2.2) and a few quirks Review by schmadde
Rating
I got this charger for a bit over two years now (the v2.2 Version with the speed controlled fan). Bought it to supplement my BC-1000 since I need to charge 6-Packs of C-Cells sometimes and 18650 LiIon Batteries.

There are a few things I do not like about it:

- the fan ist still quite noisy, forget about (dis)charging while asleep
- The charger can accept C-Cells (size "Baby"), but only two of them
- you cannot control charge and discharge current at the same time. It can only discharge NiMH with 700mA max, which is too low for my taste.

According to a review it always charges with high current, but PWM - so stress on batteries is higher than with other charging methods. I did not see any negative effects in practice with my eneloops, so it may not matter.

But I have to say, it is the best charger for the money.

- charges NiCd, NiMH and LiIon
- can measure internal resistance, so you can quickly see if a battery is "dead"
- can measure capacity, and do so at different currents (mandatory feature in my opinion)
- can "refresh" cycle, which is useful for NiMH Batteries
- accepts cells larger than AA and 18650
- Power supply is 12V, so easy to find replacement, should it die one day

It is a good universal charger/analyzer, the only real problem is that it is too loud. Also, I would have wished for the charger to accept four C-Cells, not only two.

I struggled between giving 3 and 4 stars because of the noise - but at this price it really deserves a 4 star rating (Posted on 02-10-17)

Super product Review by DK
Rating
Dit is een super goed toestel.
Refresht nieuwe en oude oplaadbare batterijen.
Je merkt dat je batterijen nog 10% capaciteit bevatten en opladen is meteen klaar...?
Een refresh zorgd voor 40, 50 zelfs 80% herstel van je oplaadbare batterijen.

Wel jammer dat de bijsluiter bij mijn toestel alleen in het engels werd meegeleverd en dat ik op het internet geen Nederlandstalige versie vind om te downloaden.

Anders is dit het beste toestel dat ik ook heb gehad.
Meet volt, Ap, mAp, tijdsduur, kracht,...

De investering is het waard. (Posted on 08-11-16)
