If I use the 2.4A port to charge a 1850 mAH battery in my Galaxy S2, will it overheat or cause any problems? Thinking it would charge faster than 1.0A

The s2 has a charging circuit that will regulate the current to the amount it needs. It would only charge faster in the 2.4 amp port if it needs more than 1 amp. The internal s2 charging circuit will keep it from overheating in either port.

I use both ports for phones including my Samsung galaxy phones with no problems although they do charge a bit faster on the 2.4A port

Well, all I can say is that I use it with an Anker battery pack, which says 1.5A input current. As far as I know these new chargers, which output via a USB connector, establish sort of connection with a device being charged. And the device itself will only take whatever it is capable of. So it's not like the charger will shove those 2Amps down the device's USB connector. Your device is supposed to support whatever current is listed on the device. Otherwise it will just use as much as it is capable of. That's what I've been told. Hope this helps.

Same here it charges really fast but it hasn't defective my battery at all. Both my covers have open ports but they are to thick and the ports to the charger dont line up.

With a 10 watt wall port my phone charges just as fast as it would normally at 5 watts. Keep in mind though that the connection is more reliable than a micro usb (i.e. you don't have to worry about breaking the connector every time your phone gets knocked off the night stand like you do with a standard cable) so it ends up charging faster than most cables. (at least in my experience)

I have the galaxy S4 and it charges really fast with a 2A charger, fast with a 1.5A charger and realllly slow with a 1A charger. The charger actually shipped with the S4 is 2A.

From the manual: "The charger will only supply the maximum charge current allowed byyour device up to 2.4 amp." The combined total allowed the 2 ports is 4 amps.

I've used both ports for my galaxy S2 and also used one for my phone and another for my nexus 7 at the same time. Just use the 2A port for whichever device requires more power or in the absence of such a distinction, whichever device you wish to charge faster.

I regularly plug my Galaxy Note 2 and my wife's Nokia 920 into either port. They both charge faster using the Tablet port, but do not seem to have any negative results. I also charge my Kindle Fire (both an older original Fire and a newer HD model) using the tablet port. I liked this charger enough that I bought another one to have more than one 'charging station' for my devices.

It should be fine. I use it with my Galaxy S4 daily in the car with no problems at all. It charges at 2.1 amps just like the factory wall charger that came with my phone. Hope this helps.

I would say this link could shed some light on your issue. http://lmgtfy.com/?q=s4+maximum+charging+current

I have used the 2.1 amp port to charge my Blackberry cell phone and it is really quick. However, it can really damage the battery if left on it too long. I take it off after about half an hour and so far I haven't had any problems.

All 4 of my chargers are set for 4.2v.I have had NO problems at that setting But, always charge new batteries as soon as you get them.I charge all my batteries, any size in it.The charger is automatic , stops charging at the correct voltage.George

I got 18500 batteries and have been using this charger awhile now and it charges mine without a problem. I don't see you having ant problems usong it on them 18350 batteries

It Probably will through the 2A port but contact RAVPower they were very helpful with me. I really like this unit, my Samsung Charge's battery sucks.Check your charger this puts out 5V 1 or 2A through a USB port

That's what I'm using one of them for. Works well, but make sure you get yourself a 2.1amp charger. You'll thank me later.

There is a good chance that the current output is not high enough to charge the battery really fast. Additionally, it is better for the battery's longevity to charge it slower. I would have to take out my multimeter to check into it, but my guess is that its good for over night charges and not super fast charges. What I recommend is purchasing a second battery and keep one charged up so you don't have down time. I personally have an S2 and when at conferences, typically pull out that second battery.

If the S4G battery is the same as the S2G battery then the charger would work. However, the charger I received, shorted out and ruined the battery it was charging.
