How many amps are the USB ports rated at?

Hello Tim. The USB ports can be used for charging one 2.1Amps device or two 1Amp devices.

I'm sorry but I don't know. I haven't left it plugged in all the time because it uses up one of my usb ports.

no, it is 5 (FIVE) VOLTS only, not 15 (FIFTEEN).So if you need 15 VOLTS (which I doubt it because all USB 1.0,2.0 and 3.0 can ONLY be 5 VOLTS)If you MISTYPED and it is ONLY 5 VOLTS @ 1.2 AMPS then it WILL work, because the AMPERAGE is how much PUSH the voltage has, so it would charge a 5 VOLTS and do it quicker than 1.2 AMPS, but it does NOT give 3.1 AMPS per USB port, it would max out at 2 AMPS.

I do not know how many amps, it handles everything I plug into it, it work well!

Usb is 5Volts with .5A maximum draw. My multimeter won't even measure the current it's drawing so I'm not sure the exact wattage. So by using the above figures... 2.5 watts maximum although I guarantee it's definitely less than that. Hope that helps. The actual unit itself has no power listing so that's all I can figure for that.

Nothing on the USB port to indicate ampage. I use for garmin golf watch. Works great and has indicator light on plug to show when charging

There are two USB outlets 1 is 1 amp the other is 2.1 amps. The 2.1 charges my phone super quickly

I have had no problems with this hub, it is a transparent little workhorse. I have three drives connected to the first three hubs nearest the on/off switches with no issues. I am not a good person to ask about the amps.

Battery: DC 4.35V, 350+50mA. USB: DC 5.2V, 800mA. Haven't tested the USB. The battery charger works well. Not sure on the speed. I haven't needed to charge one in a pinch. Usually leave it there and just get it the next day when I need it.

I really cannot say. I believe it is 10 w and it holds 2 USBcables. I have only used with Apple products and works great. Can't say about other things.

5 amps. But the power supply is 12 volts, so in reality the USB-devices you connect can pull way more than that since the USB ports are only 5 volts. Remember that volts multiplied with amps equals wattage (so 12 volts times 5 amps equals 60 watts). Nine USB ports providing a maximum of 0.9 amps times 5 volts equals 40 watts, and then you have a charger port of 2.1 amps times 5 volts which equals 11 watt. So in theory, if you fill up the entire device with USB-devices that can draw maximum power from all the ports, the maximal power draw should be around 51 watt, which is less than the power supply provides. Therefore, this hub should never give you any disconnects because of too huge a power draw, which was a frequent problem with my old USB hub.

Just note that USB 3 ports of this docking station run at 2.5Gbps/sec (not at 5Gbps/sec). This only becomes a limiting factor if you connect an SSD thorough them. For other stuff 2.5Gbps are more than enough.

I'm not sure about the amp numbers, but I'm using the hub with 2 USB3 portable drives, 1 USB2 Ethernet, USB keyboard/mouse, and USB/serial port, sometime plus more peripherals at the same time, without any problem.

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

theres no usb port can use 12 volt. all of them only can carry (originaly) 5 volts.

Don't know, but it puts out 2.1 amps. I found it enough to charge all of my USB devices.
