Review: ML-102 Charger

Thanks HKJ! I really like the two of mine, although I had to file down the edge of the charger so that my King Kong rasied top INR's would fit better (the raised top causes it to pop upward. I don't have a photo of the filing, but my initial issue was documented in the other thread with photos. I power mine with the USB A/C adaptors from Manafont (clones of the Apple iPhone ones) rated 1A output.

Garry, do you have a link to those USB power supplies?

Thanks HKJ!

Thanks for the review.
I’ve just added on to my order from intl-outdoor.
It’ll go in my travel kit.

21

Here ya go. $1.96 each. I bought three and wouldn't mind having more.

P.S. I tried to give a link earlier, but I was in a hurry and couldn't find them.

22

Thanks, I saw those a while ago but haven't been able to find them since.

Hi HKJ,

Do you happen to know how much current the charger is pulling from the 18650 when charging a phone too?

24

Thank you for the review HKJ.

I've been curious about this charger ever since I saw it the first time. Found a review on "taschenlampenforum.de" or something similar and they said it was good but no where as detailed as your in depth reviews.

Thank you for using all that time and money for us guys out here. We enjoy it :-)

25

That depends on the phone and how much current it is drawing. In my charts for usb out there is a current line.

26

Don't try charging 0.2V batteries, those are dead.

27

This is an awesome charger, the plastic is really tough.
Reverse polarity protection works. Resets the protection after has kick in protected cells and the voltage is 0.00V
When the battery voltage is too low cannot charge other devices, the blue light will not turn on and, the light not being on is a good thing because you have a visual representation of what's actually going on.

Thanks very much! Frontpage’d and Sticky’d.

Does anyone know if this can charge an IPad?

30

I charged my iPhone fully without it blowing up. I can’t verify that it is a recommended practice though.

31

No, it doesn’t.
I just tried it and the Apple says “not charging”.
It works on the Android Samsung Galaxy Tab though !

32

No problem charging iPhone.

33

Thanks for the great review (and all the other great reviews) :slight_smile:

I’ve had my ML102 for about two weeks now, and while everything works fine, it seems to be charging my 18650s to 4.16V (resting voltage after removing from the charger) - that’s not exactly a problem, but I’d be interested in knowing if this is normal - maybe it’s just normal voltage sag after removing the battery from the charger?

Of course, it might just be my cheapo multimeter…

34

Could be:

-inaccurate multimeter

-cells with rather high internal resistance

-powerful charging plug, at 1A charging current, it will finish at 100mA and therefore not charge the battery completely

-something else

or any combination of the above.

Hope that helps :)

35

It’s a good thing. Good for the life of your battery, and a sense of security that its not charging over 4.2v.

36

Both low quality (Ultrafire) and high quality (Panasonic 3100mAh with a PCB from HK-Equipment) cells have the same issue. I’m using a 1A charger though, so I’ll try charging from a USB port later :slight_smile:

Thanks!
