Does the i4X work with the iPhone 4S?



Can I leave my i4X attached even after my iPhone or iPod has been fully charged?

Yes, but we recommend you connect your i4X only when you need to charge your device. Once your device is fully charged, disconnect the i4X. There are two reasons for this. The i4X does use a bit of power while it is connected, even if it is not charging your device. Also, the device will use additional power to be on a constant charge.


How do I recharge my i4X?

Connect the i4X to a power source using the USB cable that came with your i4X. The USB cable can be plugged in to a computer or into a standard AC outlet via a USB power adapter.


Can I sync my iPhone or iPod while it's connected to the i4X?

Yes, you can sync your device to iTunes without detaching it from the i4X. Both your device and i4X will be charged while you sync.


How many charge cycles do you get with the i4X ?

The i4X is rechargeable for well over 500 full cycles. Partially recharging your i4X does not reduce the total number of full cycles. After 500 cycles, the i4X's capacity will be less than 75% of the the capacity when it’s new.

  1. Excellent Product

    Posted by Steve Manigault on 9th Sep 2012

    This is an excellent recharger for your iPhone. It recharges the phone quickly and the phone is fully functional while it is being charged. It is small and does not take up a lot of space in a bag the device itself recharges quickly. I highly recommend this recharger and I am going to buy another one. In addition, their customer service is excellent.
