Will charging speed of each output (not including usbs) slow down if I am charging multiple devices on all 3 sockets?

I have not noticed any difference whether all-sockets-in-use or just one device connected. I did not actually time the charging speed. As long as the house/wall receptacle is fully powered, each plug should be fully powered. House wiring can usually support considerably more than a charger needs. Hope this helps.

Short answer is, I don't know for sure. I recently tried bringing just my USB cables for my iPad and iPhone, and with both plugged into the USB ports, had bad luck. In the last few days, I tried the same thing, but with my iPhone plugged in to a USB, my iPad plugged into one A/C outlet and my laptop plugged into another A/C outlet and everything seemed to charge normally. So, part of my goal was leaving behind the iPad cube, but I think I still need it.

No. All the USB 3.0 share the same bus at 2.5Gbps. The ports controlled by a singe 4 ports Fresco Logic FL-1100 USB 3 controller.

It'll do it, but not at full speed. The USB output amperage doesn't seem to be up to snuff. Ours also makes a bit of a buzzing noise when two hi-draw devices are plugged in, not good :(

i do not have difinitive answer; however, if you read carefully the accompaning instructions in some of these adapters, it reads "if you connect more than one device, the charging is slow.i if you use all ports the time to charge will "increase". it will require more time to charge.

I have never run into any noticeable speed issues with this USB hub. If you have two or more devices plugged into a USB port through this or any USB hub, AND if both those devices were transferring data at the same time, the technically speed would be compromised. In most cases, though I think this would be true even if you were not using the hub, but just plugging multiple devices into multiple USB ports on a computer. All communications ultimately has to "fit" onto a single communications bus in the computer.

Other answers are correct and also, each usb port "divides" the available "speed" amongst connected devices, so if you have 2 drives connected to one port at motherboard level, you will be splitting the available bus speed between the 2 devices (i.e. expect 1/2 bus speeds (real-life will be lower) from each device when connected/used at same time).

I don't know where you got this info, but the high capacity chargers for both devices are rated at 5VDC, 2.1A. So NO. And, if you charge at a faster rate the battery will fry!

The specs provide the information you are asking. It provides 2.1A per port simultaneously which is enough to charge two ipads at the same time as quickly as if you were using two individual ipad chargers. In practice, it seems to work as advertised although I don't have any way of measuring the output while both units are charging.

I am currently using an Anker 9-port USB 3.0 HUB with no problem. It runs 7 Erupters, 2 BFL Jalapenos, and 1 USB fan with no problems.

I don't know, I use it with items plugged into all 3 regular outlets, but not with the USB plugs in use. It should work OK, it's made to be used that way.

I've charged 1amp devices in the 2.1amp outlets with no problems. I have. Blackberry which will not charge off the 2.1amp outlets for some reason but no damage has been done to the device

The hub overall is limited to 2A (2000mA). 3 of the ports are standard USB 2.0 500mA and are only powered when the host computer is on. One of the ports is marked as a "fast charging port" with 2A and available when a USB host is disconnected, though the specs state that this delivers only 500mA when a USB host is connected. I haven't measured this with a multimeter but based on what I've seen using the fast charging port to power a RaspberryPi (which is also the USB host) I believe the charging port is not limited below 2A when a host system is connected, but instead, all four ports are limited to the 2A maximum with the other 3 ports limited to 500mA each.

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.

No. Not at all. I use it at work and I'm using all 4 ports with no problems.

Hello. I had no problem with the cables (actually bought two) but was disappointed that I cannot use a USB device AND charge the computer at the same time.

The USB ports have a combined voltage of 2.5 amps. So with one connected you get all 2.5. With two connected you get around 1.5 amps each. It will charge but not as quickly as with just one connected. The AC Outlet works independently. So I currently have an iphone, and an ipad connected to the usb ports and a bluetooth speaker recharging on the AC outlet. All 3 are charging, albeit slower then if fewer devices were connected. Short answer is YES.

Yes. The ports correspond to wattage output. Using the wrong port would cause a higher watt device to charge slowly or a lower watt device to overheat.
