Can you charge two iPhones at once, or will the 2.1 amp output be too strong for a phone?

It can charge 2 at once as others have stated, however the faster charge rate of the 2.1 amp outlet will not immediately harm your battery it can cause permanent damage to the battery. Charging lithium ion or IMR batteries too fast will deteriorate the life of the battery. The smallest battery that can be charged at 2.1 amps is a 4200 mah battery, which is not in an iPhone or any other phone to date. Batteries that size are in a lot of tablets. The iPhone's battery is somewhere in the neighborhood of 2000 - 2500 mah. Other phones with removable batteries you can see their size on the battery.

I don´t have 2 iPhones, so I can´t answer equivocally. However, I have charged both my iPad and iPhone at the same time, and I have not concentrated on which output I was using, so I have charged the iPhone with the 2.1 amp. I have not experienced any problem.

I have charged an IPad and an iPhone and also 2 iPhones and they all charged fine

Hi, yes you can charge 2 iPhones at once, just that one will charge faster than the other. The 2.1amp is great in the sense that it charges your iPhone very quickly. It will and does not harm the iPhone.

Yes, you can plug in two phones at the same time. My wife and I plug both of our iPhones into either port on this device all the time when we travel.

The 2.1A rating on these types of receptacles are total amps that can be pulled from both USB, not separately. That means if you plug in two iPADs they will share the available amperage up to 2.1A total. This is probably closer to 2.5A realistically to get the 2.1A rating.

Yes it can! It has two outputs, one a higher amperage than the other, and both can run at the same time. Just remember to use the right output for the ipad and the left for the iphone to charge them in about the same amount of time, because of how much bigger the iPad's battery is.

You will have too USB port and it will give one one amp and the second 3.1 be aware from this charger ones you connect your iPhone to it it will charge for little bit thin it goes off by it sell and you have tou switch on every few minut!It's westing money DONT BUY IT!!

I have charged 2 iphones and 2 ipads all at the same time. This is for the older iphones with the 30 pin power connection but it looks like you can buy a separate adapter for the new iphone lightning connection.

A mophie can charge them both at the same time and I heard it's bad to separate the two charging ports and charge separately

You can use both ports ... I have had 2 phones charging before at the same time

You have to connect two different wires in two different outputs. But you can not charge two identical devices. For example, two iPhones or two iPads. iPad must be connected to 2A output only, and iPhone to 1A output only.

yes. this charges the two phones. the 2.4 is normally used for IPAD but you can use it on cellphones and it being 2.4 amps, it charges faster than the 1 amp. the 1am is used for to charge cell phone but it takes longer to charge compared to 2.4. this is pretty good accessories on hand.

There seems to be some erroneous advise posted here. I thought it advisable to repeat this:I own an iPhone 5s. It does not require a 2.1 amp charger. In fact, it will not charge faster with a charger rated above 1 amp.Also: the Apple Brand charger included in the box with an iPhone 5s purchase is clearly marked "5v, 1.0 amp".Fact: An iPhone will only draw a maximum of 1A of current, no matter the charger.

No. It will charge 2 iPads OR 2 iPhones. Apple devices have higher amperage requirements than Android

Yes! If you have another usb cord that you'd normally use to connect/charge the second phone, you can plug it into the port marked for 'Apple' devices, and it will charge both, simultaneously.

There are two USB outlets 1 is 1 amp the other is 2.1 amps. The 2.1 charges my phone super quickly

Checked out the Scosche web site and found a reVIVE II - Dual USB Car Charger (USB12V2A) which purportedly has two 1.0 Amp USB outlets. It's anybody's guess whether this a different charger than what Amazon is selling, but it appears to be better equipeed to accomodate two iPhones at the same time.Hope this helps!

It will be fine. Your phone will only draw the current it needs to charge. The nice thing about this one is that it can charge two phones at once. Or other devices--iPads, Kindles, etc.

As long as you have a USB cable for your phone....thing is great.....we fully charged two phones at once and still had juice left in it
