I have the same question. What is the output of the USB ports ? This is very important for us.

These are charging ports only. According to the package 5V, 1.5A. "For residential use only". FYI Surge Rating UL1449 (3rd Edition) VPR=600V In 3kA, Joules Rating 555

Most of the answers are reviewing the older version. In 2014 the part was upgraded to provide 2.1A for charging. The surge rating was also moved up to 900 Joules.

I've never measured it with a DMM, but I can directly plug all of my Apple devices into the two USB ports for charging.

Have no idea. Likely 10w..??? It takes same amount of time to charge my iphone and ipad compared to a regular plug

There is just the 2 usb ports in the front and 2 in the back. They are not 2.0

Hi. Spec's are correct. One USB 2.0 on the left and two USB 3.0 on the right. There's an HDMi out port next to the two USB 3.0 ports that in photos could look similar to the USB ports. Hope this helps. BTW, I am still pleased with the performance of this unit. Overall, I think it's a tough value to beat. Good luck with your search.

no, you need the included ac adaptor(is a 12v output), usb is only 5v output.

Yes, that's the purpose. Plug into AC outlet, and you get many outputs, including USB output.

Mine did not include the usb adapter, thus I am returning it. Possibly a packaging oversight, but nonetheless, it was not included.

I'm not sure what to tell you. Mine has been working great since I've received it. I would recommend this product to anyone. Have you tried a different USB port? Try asking for a replacement, the price is just too good.

pc usb ports typically put out 0.5amps. these power packs can do 1A and 2A, it probably can.

Sorry. Don't know this answer. I am not for sure what this would actually matter in this case as you hook this up thru USB.

There are three ports. Mini, small, and full size usb. Will none of them work?

Do you mean the voltage output? If so, it outputs USB voltage (5 V DC at a max of 2 amps).

To the best of my knowledge, no. I believe the USB ports are only for interfacing with storage devices like external hard drives and flash drives.

The unit only outputs 5 volts. If you add more devices to each USB port, it will split that 5 volts.

I'm afraid I couldn't tell you that, but I doubt it. I'm in Mexico & the current is the same as the US. All I can tell you is, the USB ports don't work! Find something else!

I'm sorry, but I have no clue. The USB plug worked fine for me. Perhaps it is defective.

No, all USB ports on computers are essentially the same except for the power output. USB 2.0 ports output .5 Amps (500mA) while USB 3.0 ports output .9 Amps (900mA). USB ports that are on AC adapters and phone chargers are capable of outputting much more power.

Marty, I know what a USB is...and it does not connect via USB. The others you mention are not familiar to me, so I'll not comment on those.
