Even tho this has 5 ports if I have 2 iPads and an iPhone (3 devices) i have maxed its use at 5.2A?

it charges 2 iPads easy and 3 mobiles whatever the brands I tried it my self it really works

I need one of this to charger 2 IPhones 4S, one Ipad 4th generation and an IPod nano. Is this product correct for it? Thank you!
1778987
Correct... I haven't tested to see which port(s) would be 'ramped down', but the effect would be that one or more devices would charge a bit more slowly. Chances are good they will all charge, and pretty fast (you're only "missing" 200mA), but it won't be all three devices at full speed.

I'm not electrically savvy enough to answer your question scientifically, but I do know that I had five devices plugged into the charger of varying amperage in ports that weren't necessarily designed for them, and everything charged fine, and quickly, even in Japan where the current is weaker.

i purchased this unit and am currently using it to charge 2 iPad air, 2 iPhone 5s and on android LG2. All five devices charge fine and charge quickly. Equally important however to be sure and use only certified charging cables for each device. I tried less expensive non certified charging cables and they would not charge at all.

Yes, you will max out with 2 iPads and an iPhone (or similar combinations of a Samsung Galaxy 4 or other smartphone or device that has the ability to charge at 2A or higher). So it's not perfect, but it was the most bang for the buck that works for my needs. Of course, you can always charge at the lower A, but you just won't charge as quickly.

My experience has been this. My iPhone 5 syncs beautifully w/ my iMac thru this port. But my iPad 2 does not. I have to plug it into the back of the iMac. I haven't ever researched why. Other peripherals have plugged into this well also.

Both ports individually will provide up to 3.1 amps as long as there is only one device attached. When two devices are attached the "A" port gets the bigger share of the 3.1 amps and is the only port to use with an iPad. Clearly, with two devices attached neither will charge as quickly as when any one device is charged by itself. The 3.1 amp total combined output is inadequate to charge two iPads simultaneously.

USB outlets are marked 1A(upper) and 3A(lower) BUT the total is limited to 3.1A.So one at a time you can charge any iPad or iPhone BUT since iPad Air requires 2.4A may have a problem combining with another device. Earlier iPads may not be a problem combining since they require less amperage.

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.

I successfully charge 1 iPad, 1 iPod and 2 iPhones simultaneously. Hope that helps.

All multiport USB chargers will split the power between the ports but this one is 3A. One port will get 2A and the second 1A so it is sufficient to power all new devices that require 2A charge (like iPad and large screen smart phones) and use 1A port to power second device without compromising on time. Just make sure to use original device cable.

in theory all ports should be able to charge an ipad and iphone, but the longevity of the port is very short, not recommended at all

I dont know max but I had 3 devices connected in my home network with great results.

No. It has two ports capable of delivering 2.1A each (the same as your iPad charger) = 4.2A total. What you get is two ports instead of one, which can be convenient if power plugs are scarce.

can charge an iPod and iPhone 4S at the same time so I would assume that it would charge 2 iPads

Not exactly sure how it shares out the power over the ports. I can say that you can charge an iPad and an iPhone at the same time using both ports. Though only one port will charge the iPad when both ports are in use.

'Over-amping' a device is impossible by the laws of physics. So no worries there. The amperage listed per port is the maximum that port is capable of supplying. A device will attempt to consume the amps it was designed to up to the limits of the port it is plugged into. More amps means faster charging. This is all before Apple enters the picture because they do strange things to try and force their customers to buy only their products. So a 2A 'apple' port may not supply the full 2A to non-apple devices and vice versa. Unless Apple got their act together which I doubt...

The specs provide the information you are asking. It provides 2.1A per port simultaneously which is enough to charge two ipads at the same time as quickly as if you were using two individual ipad chargers. In practice, it seems to work as advertised although I don't have any way of measuring the output while both units are charging.

No, one port is designed for an iPad and the other port is a lesser watt output which is designed for your iPhone. I have two of these and they do work great.

This hub meets the USB 2.0 standard of 5VDC at 0.5 amps maximum per port. Apparently some Apple devices require more current than this.

I don't know about 4 iPads but it charges my iPad, iPhone, Kindle Fire and runs my GPS at the same time !
