Huangao All in one Charger [ HG-1210W ]
Im looking at the Huangao all in one charger , and as the tittle suggests it can almost do it all .. 3v and 3.6v as well as 1.5v cells .
Its rated 800mA charge current , but thank goodness the actual charge current is only half that [ 400mA ] . When testing the charger this particular sample was noisy to say the least , making all sorts of noises , you would actually think it was a mechanical charger rather than electronic
Well Im glad to report it works , it can and will charge AA's , the bad news is it does it , I would guess the same as the WF-139 , whereby it stops every second or so to check the battery and then continues , making for what we call pulse charging . With a AA @ 1v I detected a pulse between 200mA and 400mA , and this is probably just the charger stopping and re starting as it goes along ..
With the battery @ 1.26v I detected a charge voltage of 1.33v and a voltage of 1.44v in the unused bay . With the battery @ 1.37v I detected a charge voltage of 1.42v , and a voltage of 1.5v in the empty bay .
The blinking light went fully green around 1.4v and I left the battery in there till it hit 1.46v [ Sorry , wasnt set up to measure current at this time ]
18650
With the battery @ 3.53v charge current was 440mA , charge voltage was 3.58v and the empty bay was 3.66v
@ 3.71v charge current was 400mA
@ 3.91v charge current was 380mA
@ 4.05v charge current was 200mA
@ 4.12v charge current was 100mA , charge voltage was 4.13v , and the empty bay was 4.15v
@ 4.15v charge current was 80mA , \
@ 4.22v charge current was 15mA . charge voltage was 4.22v and the empty bay was 4.23v .
I did not detect any sort of pulsing when charging the 18650
Conclusion
This is not a dual channel charger , this charger does not terminate charging , but continues to charge the battery and overcharging is inevitably possible .
The charger was for some reason noisy ?
It will accept 12v input , charges a number of cells , the little blinking light goes green long before max voltage is reached , around 4.14-4.16v with the 18650 , but trying for 4.2v may be problematic . Seems to handle 1.5v rechargeable's well , ? [ pulse charging ] .
The charger is available from a lot of sources , and is some what inexpensive , and wont break the bank . So if you need a charger that can do Li-ion + AA's [ 1.5v ] and run from a 12v source .
Bottom line , the charger requires monitoring , it is not a safe charger , it is in fact a very cheap charger that is capable of doing the job , but requires close supervision . If used carefully , this could be a valuable tool , if used carelessly , buyer beware !
