How long does it take to charge a Samsung galaxy S series cell phone using one of this?

It takes 2 hrs 45 mins to fully charge my S3 (0% to 100%) with a 3 ft cable. If you use a longer cable, it might take longer. In general, device will pull power at a rate of what it is capable of. Higher amp will not necessary charge your device faster. I believe S series cell phone only requires less than 1 amp for charging. This charger will be more than enough for your cell phone. This charger is good for device that requires 2 amp+ of power source. Also be aware of specs of the charger. A lot of dual port charger claims to support 2+ amp. However, the total is split between the 2 ports (ie each port can only supply 1 amp power source). One more thing, Apple charger (even though it supports 2.1 amp) will not work with Android devices. It will work. However, it will be painfully slow. You might get 1% per hour. Hope this helps.

Not sure about a Samsung Galaxy S, but I can give results for the Samsung Galaxy Note 3.....10:18pm 2% Start11:50pm 88%12:32am 100% EndSo, basically 2 hours 14 minutes to do a 98% charge. It seemed to average a little less than a percent every minute up to 88%, then it seemed to slow down by taking 42 minutes for the final 12 percent. Not sure why.

I have a iPhone, It charges my iphone 2x faster rather than using the 1 amp charger that came with the phone. Hope this helps.

No, it is quite the opposite, actually. It takes an extremely long time to charge my Galaxy S4.

My galaxy charges in a couple of hours. You might want to check the pins where it connects to the device. If one is bent may not be making a good connection. You will need a good light and a magnifying glass to see into the plug hole.

It really depends on the Rating and efficiency of your charger. The stock Samsung one takes ~2X longer than the Motorola ones I have. You also need to factor in length of your cable and quality. This can sometimes decrease the amount of charge that gets to your battery. Turning off energy using features while charging also helps it charge faster since the phone is using less and more can be put to the battery. I would say 3-4 hours with my good Motorola chargers and 4-5 with the Samsung ones from 1%. Certain % ranges take longer than others so do not rely solely on the % to tell you how long.

It depends on how low the battery level is. If you are charging it from 0 then it will take about 1.5-2 hours.

It takes about an hour to fully charge an s107. The chargers output is 5 volts at 0.5amps.

I haven't gotten a chance to use it yet but figure it this way ... If you have a newish Samsung device or IDevice and it charges it should be at least 1 amp. If it fully charges a device like the Samsung 4 its probably 2 amps. I was slightly peeved when I got this and it didn't have the normal conversion sticker like other solar usb devices. We both have to hope we didn't buy an 8800 maH battery that doesn't charge anything in the 21st century.

It will vary.. If you are not charging a phone, and the USB supply (you will need to provide this) is large enough in about 2 hours. If you run it down about 4 hours... all depends on your usb power supply.

Same way you charge your phone, from a computer or a standard USB charger. There is a mini usb input port for that and the unit comes with the USB cable. I believe it takes 2 hours for a full charge from empty.

My 2 cellphones use this kind of batteries. From my experience it takes about 3 to 4 hours to fully charge them. They seem to work fine for me.

I don't have an S4, but it will charge an S3 in the sme amount of time as your normal charging through a wall charger. I haven't timed it exactly, but it seems the same if not faster. On one trip, it's charged my phone a couple times and my ipad. All be it, they were low on battery, but not empty. Hope this is helpful.

It depends on what charger you use, and on what setting. On a smart charger, it is about an hour, two at most. On a "dumb" charger, maybe five or more.

30 minutes to an hour. Depending on which charger u have. Quick charger 30 minutes.

I have never actually timed it I just charge it over night and in the morning it is good to go. It takes longer than charging your phone through the wall charger. If I had to guess it probably takes about five hours.

When I just let the phone sit and dont use anything on it, it takes 1 1/2 hours to charge and faster if you turn your phone off and charge it.
