Which of the two USB port provides 2.1 amps?According to the instructions only one port provides 2.1 amps, but neither are labeled.

the way i see it if you only use one port at a time you get full power. 1/2-power when both in use.

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.

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'm surprised most people have not noticed this being USB 2.0. To achieve anything close to advertised AC speeds you need 3.0 at best.

The 2.1 amp is for Apple, the 1 amp is so you can charge other portable devices simultaneously.

The USB port outputs 5V DC, the Amps it can provide is 1A making the Wattage 5.

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

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

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

The specification sheet from Cooper would lead me to believe it's 2.1A combined for both ports as the MilliAmp rating for teh entire recepticle is shown as 2,100MA, not 4,200MA as it should of both USB ports could pull 2.1A independently. http://www.cooperindustries.com/content/dam/public/wiringdevices/BuyersGuides/RBG/B/RBG-B-Sec-14.pdf

I would check with Wagan to be sure, but as near as I know the output from any port is standard USB at 2.1 amps. I hear some Samsung devices have problems due to their proprietary wiring of USB.

I am not sure I can answer your question but from the info I read from another reviewer who said he took the device apart, he said that the right port did provide 2.1 amps but that the left port was just some resistors and did not supply as much current. He did not say anything about what both of them put out at the same time. You might try a search on Levitons website where they provide the specs. We use ours daily on both ports and they work great for us.

Haven't tested this one specifically but almost all that have been legitimately tested that are similar to this one have 2.4 total so if you have one item plugged in it will draw up to 2.4 a. If you have two plugged in the unit will allocate the 2.4 amps between both items but no more. There are plenty of chargers out there that will deliver a full 2.4 amps to each usb port but they are a little more expensive.I hope this helps and good luck!Chris

Yes, there is 2 USB ports on there, one has a 2.0 amp output that will charge it perfectly almost 2 full times in one day

According to the very small name plate the rating is 5.1 volts at 0.85 amps. If you need more current many two port chargers deliver 2 plus amps. Search Amazon for "USB Charger" I have one from POWERGEN.

Most PC's and chargers limit the current to about a 1/2 amp. That's due to the USB 2 spec. There are a few, such as Apple, Kindle, and others, that charge at higher currents. I would have no reservations using this extension at 2.1 A. Go for it.

Yes, one is for data and the other is for power. Sometimes a USB port won't supply enough power through one port. I have used an adapter that just had one USB. This one does require the use of both.
