Which port is the 2.1 amp output? Or is that if I only connect 1 device, either will charge at 2.1 amp?

If you look at it with the words facing up (LED light down) the one on top is the 2.1 Amp charging port

The 2.1 amp port is the one closest to the edge of the device. New Trent has said it will be labeled properly in the future.

Using the correct USB port, the NT90C should be able to read the number of connected electronic devices and output 5V/2.1 (max) to the device that is connected. Charge cables with no device connected to the NT90C will have no effect to the max output.

The IMP90C shares the total 2.1A if both usb port is used. The top (furthest to edge) usb port will provide 2.1A if only port used, that's why when charging one device, it is able to charge more quickly.

I believe it's the bottom USB port. Right above the "10W USB Power Adapter". My Note 2 charges considerably faster on that port compared to the other. Same goes with charging two different devices. That bottom port still charges faster than the other.

Either port will charge fine but the 2.4 is faster. Its similar to the difference between plugging it into your computer to charge (1 amp slow) or a wall charger (2.4 amp faster). Both will do the job one is just faster.

The Discription says "Plug in to Any USB 2.0/1.1 Interface". Hmmm! Is this just for Power?

I really wish people would look more closely at the product. I myself am trying to find the same information as you and almost bought this unit. However, taken directly from the manufacturer's website (Accell), I found the following: USB CHARGING: 2 Ports, 5V, 2.1A Shared. So unless the manufacturer incorrectly described it's own product, this, just like most others, have a total of 2.1A for all usb ports. If using both usb ports at the same time the 2.1A will be split, reducing the charging time of 2 devices (ipads, tablets).

I believe each port is rated it at 2.1 amps, which the max for each port, I hope this helped

This unit has a USB outlet capable of providing 2.1 amps. All you need is a cable with a USB A male plug on one end and a plug that will fit your device on the other.

If a device requires 2 amps to charge, but you only supply 1 amp, it will not charge, and it, the device will strain the charger, possibly damaging it. This is dependent on the battery type, charging circuit etc.It's best to have more available current than needed.

Should be rated at 2.1 amp. Charges as fast as my Belkin charger rated at 2.1

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 unit has two outputs. 2.1A and 1A, the 2.1A will charge faster, you can use it for any device. You should use the 2.1A for the iPad, or any tablet for that matter. I would only use the 1A if you need to charge two devices simultaneously.

Drew. There are two outputs with different amperages. 1 and 2.1 amps. Look at the picture above. If your phone charger is lower than 1.75 amps, I would use the 1 amp, just to be safe. If it is above that, it will charge faster on the 2.1 amp output.

2A = 2 Amperes, as in current for charging tablets and more power-hungry devices. I don't know the answer, I'm just clarifying for those that don't get it, and those that might be able to answer.

I'm not precisely sure on that. The thing has 2 USB ports. One for Apple devices. The other for anything else. They are stamped "A". And. "NA". The little pamphlet says you'll get full 2.4 on the A port but if you use both at one time the power is divided & I don't remember the exact breakdown

one output port is for 2 Amp, the other is for 0.6 Amp, and the cable micro USB is for 2 Amp too. This info is from the case and in the manual. The USB cable shares the 2 Amp port outlet.

I'm not a genius, but it appears to function the way you describe. The instructions indicate that the "A" port (I assume the "A" stands for Apple) will put out the 2.4 A when used as a single port. The second port, labeled "NA" is for non-Apple devices, although I charge my iPhone with it. The catch is when you plug in two devices, the overall output is still 2.4A, but it is distributed to both ports.Hope that helps!

As others have stated you can't exceed 2.2 to 2.4 on a given port, but that wouldn't matter, because it isn't the charger that decides the amps to charge at it is the device. The only thing the cable and chargers do is supply enough amps and low power loss. An average device won't pull above 2 amps regardless of the output of the charger. The S4 pulls 1.8amps at its full draw and its oem cable and charger are rated for 2.1 if i remember correctly.

This is a EU charger. The 1.0A port is for phones and smaller devices. The 2.1A port is for tablets.
