What is the amperage of each port NA and A? Why the SPECIAL case for an Apple?Will my Android charge at 2.1 amps on both usb ports?

I am unsure of any of these answers. They are all technical questions if you ask me. I have not even used mine yet. It is in the car still wrapped in plastic. Sorry.

The USB ports appear to be parallell and will split 20 Watts @5 Volts or 4 amps. I have been able to charge my Blackberry Z10 and my daughter's iPad II simultaneously without a warning from the devices. It is a sturdy charger and fits snugly in the power outlet.

Thanks GB Tech. I WILL NOT be answering any more questions like this from Amazon - even if I know the accepted answer.

This device does NOT charge at 4.2 amps or even 1 amp in your car. It's power output specs are for 24 volt trucks and military vehicles, not 12 volt cars. The maximum input is 1,000 milliamps. That is 1 amp at 12 volts. Unless the manufacturer has figured out how to break the laws of physics (conservation of energy) there is no way that this device has more than 2 amps output at 12 volts. I know. I was dumb enough to buy one, only to watch my battery drop while "charging" and using GPS. I estimate that the charger was putting out about 700 milliamps in the android output.

I think it's restricted to 2.4 amps per port, however, this should not be an issue, no device that charges using USB pulls 4 amps

I know what you want to know, but your question has a slight error. You want to know how many mA (milli-Amps) this device puts out- not how many mAh (milli-Amp-hours). From the product description: Dual USB Charging Ports: Provides 1.0 amp of current when charging one device, and 0.5 amps of current to each port when charging two devices from AC or DC power. For AA or 9V charging, single port charging is supported. DC 5V +/- 5% 1000mA MAX So if your device is capable of absorbing 1000 mA (1 A), and you leave it connected for 1 hour, you would deliver 1000 mAh. Two hours, 2000 mAh, three hours, 3000 mAh, and so on. It's perhaps a fine distinction but it is important. HOWEVER- I think you may be disappointed if you try to use this as your primary charger for a device that requires 2100 mA of charging current (note I did not include the 'h'). It will only deliver 1A maximum, so if your Galaxy Tab will even charge from this device, it will take approximately twice as long as it would to charge from the Galaxy Tab's original AC adapter. HTH

Its the standard micro USB charger that has become the standard. I use it for all my phones which are Androids and for my Android Tablet. The Apple products are different and you wont be able to use this for Apple products.

It will charge an iPhone (2.1) and an Android phone (1.0) at the same time, no problem. I'm not sure about 2 Android devices at one time. My understanding is the 2.1 slot is for Apple products and I don't know if using that slot for Android products would be okay or not. Sorry.

Im sorry but I dont know what 2.1 A or 1A port is,lol I can say this. We have Iphones and it charges those.It also charges my gf I pad and the kindle fires the kids have and my e pad. It does not charge my Play station 3 controllers. I ended up buying another one after my 1st purchase so we now have two.One for the bedroom and one for the family room.I think its a great item to charge multiple things with one plug in instead of having outlets through out the house charging phones ect.

Dr. James M. Peterson - You are giving INCORRECT INFORMATION. Android post is 1.5a and not 1.0amps. Please change your information.

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

It has two USB charging ports on it. One is a 1 Amp port, used for charging tablets such as ipad or kindle fire, and the other port is 500 Milliamp, which is used for charging normal smartphones and ipods, etc...You can use the 500 mA port to charge tablets as well, it is just much slower

yes, each will get 2 amps, but be careful not to plug more than that in. I charged two tablets and my cell phone a few times and the charger died. It was great as long as I never plugged more than 4.2A of draw in, but more than that seemed to cause it a lot of pain, and a very quick death.

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.

The amperage is 3.1A. It comes with two USB ports - one is 2.1A and the other is 1.0A. Thank for your inquiry. - CrazyOnDigital

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.

Sorry, I don't know the answer on the exact amps. Is there a specific reason why you might want 2.1a on both sides? All I can tell you (a non-electrician) is that it supplies enough power on the right side to charge an ipad (but not on the left). So, I suspect that it can't be sharing (1A on each) as that would not provide enough power on the right to charge an iPad.Hope that helps.

The AC adapter says 1A on it. It appears that it provides the max of 500ma per port. I connected my android phone to charge off of the hub, and it's reporting that it's being charged via "USB" which means it's not drawing more than 500ma. When I charge my cell with a direct usb wall charger (that came with my phone), it reports being charged via "A/C" (1amp). The power cord is 5 feet in length. Also, the USB connector (which is attached and can't be disconnected from the hub) that plugs into the computer is also 5 feet in length.

To answer your question yes is port supplies the 2 amps. Each USB port is dedicated. Unlike a hub that would split power. I had two iPads connect as well as one iPad and one iPhone and it worked perfectly

Yes, it can be used to charge two Android devices at once. My understanding is that the apple port only charges an Android device at 1.5A, but the Apple device at 2.1A. It charges my S3 pretty darn quick though.
