ML-102 charger

Cheers mate,

Yeah we have copper coins here :slight_smile: probably too much work tho.
I was gonna order some stuff from Hank so will get him to drop those in aswell.

Thanks,

Alex

Has anyone tried the ML-102 with a high current phone like the Galaxy S 3? How well does it work with such phones?

Please enjoy your time here, wshyang!

Thanks!

When LED is green and under charger still glows red means it’s charged? Or does the red glow underneath have to turn off aswell? Batteries can be hotswapped in these chargers? Or do I have to disconnect usb charger everytime? thx :slight_smile:

Both LEDs have to turn green. But if only the one on the inside is glowing red, the cell is charged to about 95%.

Galaxy S3 needs only 1A, that’s not high current by today standards (2.1A is) :slight_smile: It works fine, but it’ll charge a little bit slower than from wall charger.

Thanks for that info, I didn’t know that! :slight_smile:

love this charger too, got a white one now, 2nd white one on the way. seems to provide proper charging, therefore its my fav portable charger…

I have posted a review of this charger

Sorry to bump up an old thread……………is this ML-102 suppose to be able to charge an iPhone 4S? I just receive this charger but it cannot charge my iPhone. When I plug in the cable from the charger (USB out) to my iPhone 4S, it glows bright blue and after ~5sec drops to a faint glowing blue. The iPhone did not display the charging logo. Have tried with different USB cable, can’t seem to work. I read that some charger needs a sense resistor on the ID pin to be able to charge an iPhone 4S, is that true?
It works fine charging up all my 18650 to ~4.214V though.

Flame, I can tell you it charges my 4s fine. In fact it is doing that right now.

Mine worked with my old iPhone 3GS, but I have not tested on my new iPhone 4 (don't own a 4S).

I’m not sure about the 4s but it did charge my 3g and it works fine with my new 5. Are you sure the battery is fully charged? Sounds like the voltage is lower than the required input.

I'll add that I have tested mine on the 3G, 4, 4S, and 5.

Ok. I think there’s something wrong with the charger. Wouldnt charge my MP3 & my wife’s Samsung phone too. I’ll try measuring whether there’s output with a multimeter later.

Whats the best 18650 battery to use with this charger?

Does it have a protection circuit, or should I use batteries with protection?

My EDC is one with a protected NCR18650B, which I purchased from Kumabear.

When using the usb output, it need at least 3 volt from the battery at 1A.

Find the "Discharge capacity down to 3 volt" and look for the batteries with the longest blue line (That will be the 3400mAh batteries).

It has a very good protection and will work fine with unprotected batteries.

A protection does add a extra layer of safety, making it slightly safer.

Some cables can do this. I don’t know why but my ML-102 does the same thing with a cable I had to re-solder due to line breakage. The cable works on some chargers, like the one I’ve built myself for my IPhone and a 4x18650 emergency charger I had from eBay but doesn’t charge with the original Apple charger or ML-102. So, try replacing your cable, your cell inside the charger, or the device you’re trying the charger on. My ML-102 can even charge an IPad with a 26650 inside.
