It is for an emergency quick charge, if you don't have a hard charge. Works great for 4s.

You charge this portable battery by either plugging it in or placing it on a powermat. It has a wire for both android devices and apple devices (doesn't fit in iphone 5, 5s, or 5c). It happens to work great with the iphone 4s. You get about 2-3 full charges when you use it with the iphone 4s.

Hi Attia S.Yup it has a 4S plug on the side that charges the iPhone 4 series. I tried to charge my iPad also, but it doesn't work with it for some reason. Works great for 1 full charge if you're not using the phone. My suggestion is to download a battery "tuner" app which will help charge the phone faster and more effectively . Otherwise the charger works great.

I don't have an iPhone, but I do have an iPod with an old style connector and it works great.

It is like a charging brick. You have to charge IT, either with a usb cord or on a powermat (sold separately) then you can take it with you to charge your phone or whatever. There are Apple and micro cords attached to the brick that you just plug into your phone. Very nice because it isn't exclusive to one thing (e.g., you can charge any micro usb phone.) I used to use a mophie juice pack for my iPhone 4 (until I switched phones). It is also a very nice item you might consider.

I have a iphone4 and it's works great! I was having trouble with people always wanting my phone charger at work, that I'd find myself having to ask to use my on charger so I started carrying the powermat in my purse so I could recharge when needed! I love it bought my son one too!! But you have to remember to recharge it after you use it! Hope this helps!!

The backup battery can either be charged with the Powermat Mat (the easiest way IMHO),or with a micro connector charger.It will work with the older type Iphone connector that is on the 4S.They have newer battery backups that work with the new lightning connector on Apple devices also.It is a very cool system.

It should work for your 4s. It also works for my husbands Samsung. We have three so far & may get a few more.

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

Yes. I use it for my iPhone 4s all the time. The charger has a USB port, so you just plug your iPhone charger into the USB and you're off.

This works fine with an iPhone 4s and has been tested working with an iPhone 4. I bet it would work with an iPhone 3gs.

My iPhone 4s works fine with it, and I think it should work with an iPhone 4.

Absolutely works on the iPhone 4s - can't say if it works on the iPad since I don't have one. If the port/cable are the same, then my guess is it should work.

Hello..it does work on the iPhone 4S. I used it on my computer to change the HD, and RAM. Also when the screen on my iPad broke I used it as well. Hope that helps answer your question.

I believe this would work with the iPhone 4s. The opening is very universal. I bought an extender for where the phone plugs in but we ended up not needing it because the place that the phone sits down in is bigger than we expected it to be. We have the 3GS though. My stepson has the iPhone 4 and it will fit in it, hope that helps.

I'm not sure I couldn't get it to work on my iphone 4s. Best to ask the person that is selling it or got to their website under support ask them.

I bought this for my dad. He has an iphone4 (not sure if it's a 4s) and it works great.

An answer placed here by another user is incorrect. The correct answer is "yes" it DOES work. iPhone 4S uses this products connector sizes on both ends.

Mine didn´t work on an iphone 4s on OS8.1.2. The manufacturer's recommendation was to purchase an adapter. For me, this is a scam.

It works with my 4s iPhone. I'm satisfied with it for the price. Doesn't answer your question but hope it helps.
