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 :-)
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 for the great review (and all the other great reviews)
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?
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
Nope, you’d need something more powerful for tablets.
E.g. those 4x18650 (parallel, not 2S2P, because parallel versions are much safer) boxes from eBay, with 5V 2.5A output.
Populate it with 4 unprotected Sanyo 2600mAh cells ($22 for 4 from Kaidomain), and you have pretty much ultimate power-bank that can either fully charge 1 tablet, or fully charge 4-6 modern phones.
I found this one which seems to be good and also includes a cable with a specified current rating, which is nice since I haven’t been able to find a cable that included this.
I was wondering if I have 2 of this charger and say I have 1 discharged 18650 and 1 fully charged 26650, could I use the 26650 to charge the 18650 with these chargers?
I see, this just suddenly came into my mind, it was a funny question indeed, what’s the purpose to charge a 18650 w/ another 18650 x). I edited my post, 26650 charges a 18650 or vice versa makes more sense…
