how fast it charges iphone 4s

It depends on how much it needs to get back up to 100%. I wasn't really timing it, because I was busy doing other things. One reviewer said about 15 minutes, and thatmay be about right.

It literally fell apart on the first use. The part that goes into the phone fell to pieces as I tried to take it out. Worthless. It was difficult to get it from the phone port.

The one we ordered did not work. It broke first thing when it was taken out of the package and tried to plug into the phone. I ordered this for my manager. I do not recommend this item at all.

I attached my daughters 4S and within 25 mins it was charged. It could of been sooner for all I know. But I checked it at about 25 minutes and it was charged.

Greetings. The iClever wall charger will charge iPhone 4s and iPad mini at the same time. Thank you.

This device charges my iPhone 4S twice. It doesn't charge it fully to 100% twice. It charges quickly from low to 95%, but after that point, the pace of charging seems to slow way down from 95% to 100%. Not sure if this is an issue with the device or the iPhone, but I don't need that last 5% anyway. This device works pretty well for its size and I would recommend it.

There is no set answer to this question. It all depends on your phone. If you have things like wi-fi, Bluetooth turned on or "Hey Siri" turned on, or lots of notifications such as Twitter/Facebook/sports etc. it takes a lot longer. If you have the phone turned off and charging it can charge very quickly. Especially if you use the two higher amp ports. if you are really looking for a quick charge, you should search for "quick charge" device chargers

It works great for 5s. It charges as fast or faster than the wall charger. Very solid.

Yes, I have one and it charges it just as fast as my charger I received with my iPhone.

Yes it will charge the iPhone 5s from empty to 100% within approximately 2 hours.

Depends what you're plugging into. If your plugging it into a power source and just using it as a basic extension it should charge at about normal speed.

It's 2.4amp total. If one device is charging, it would pull a maximum of 2.4amps. If two things are plugged in, they would share the 2.4amps.

Just a further follow-up, it charged my iPhone from approx.15% to over 90% in about an hour. Hope this info is helpful.

It depends on the device. My iPhone 4s took about a half hour to charge up. It was down to 50 percent. It charges at the equivalent rate of an a/c charger.

I charge up both my IPhone 4S and my external battery case (which is great) at night. I use my phone all day for text; phone calls (in and out bound); and 2 email addresses. I work from 6am - 6pm and there is still battery power left. Before this extender I only had about 3-4 hours of battery and had to charge in my car (I'm in sales).

It works for iPhone 4s. It's capacity can support about 1.5 charge for an iPhone.

This works great with the iPhone 4s. The "smart" port will charge the iPhone 4s in just under an hour, similar to how fast it will charge if you plug into an iPad charger. The other two ports behave like regular iPhone chargers.

I originally bought this cable for my iPhone 3GS however I have used it to charge my iPad & also my sons iPhones. We all now have the 5c & it works to charge those also as long as you have the adapter so, I do not know why it would not work for your 4S. It does work with the apple power block. Only thing that I do not remember is if the computer will recognize it when you plug it into the USB port. I really like the cable because of how heavy the cord is & the length of it. The only thing is that you will not be able to keep your phone in your case when you charge it because of the thickness of the power end that plugs into the phone.Hope this is helpful to you I originally bought this cable for my iPhone 3GS however I have used it to charge my iPad & also my sons iPhones.

Sorry I have only used iPhone 4S on it. That works fine. It does charge it, when plugged on.
