When traveling, I probably will have the iPad 2, iPhone 4S, a USB backup charger, and some misc devices such as a Kindle Fire and a Sony digital camera that uses USB to charge its battery. So instead of hooking them all up to the computer to charge them overnight, in the event that I actually need to charge every one of them that night, is it possible to use Apple's 10W USB charger that Apple makes (it is 100V to 240V compatible): and then hook it up to any USB hub, such as this Belkin 7-port one: and be able to charge all the devices listed above at the same time? (by the way, it seems that the smaller Apple USB charger with the green dot is 5W, so probably that one is not very powerful to charge all devices at the same time). I saw people writing reviews on Amazon that the included power adapter is not charging devices well, but what if I use this Apple 10W USB Charger and not use the included adapter with the hub? Supposedly, the 10W should be distributed to all the ports (divided up). So if one port needs 5W, and the other needs 5W, then it can charge 2 devices?
Are you saying if 3, 4, or 5 devices are connected to the hub, then it actually requires about 15W, 20W, or 25W? (and if all 7 ports are used for charging, then 35W at least?) Is the 5W what a typical PC or Mac USB port can provide?
The USB-C Digital AV Multiport Adapter lets you connect your USB-C-enabled Mac or iPad Pro to an HDMI display, while also connecting a standard USB device and a USB-C charging cable.
– Jan 3 '12 at 20:23. Apple use some tricky schemes to identify battery chargers and compatible devices. The sense resistor is common and it is what is responsible for the message with some combinations of devices. See the fun they had working out the right sense resistors when designing the. (and do check out ladyada.net if you like this sort of thing, there are some very clever hacks) I don't think your iPad will charge at all with the hub.
I have a and when connected the iPad just says because it detects that it is not plugged into a high power USB port. Apple provide some explanation about high power in this - basically the port starts out supplying the usual 500mA maximum and will supply extra power if capable. The USB hub is almost certainly not a high power port, even if it is a powered hub.
And it won't have the correct sense resistors to tell the iPhone/iPad that it is a device capable of charging it. So even if it could distribute power from the 10W adapter the devices could not recognise that they were connected to a 10W adapter. If you only carry one charger then it should be the 10W adapter but you really need to connect the iPad directly to it.
While the iPad can charge from the 5W adapter it will take much longer and you would probably not get a full charge on your device. I think your ideal combination of charging devices is one Apple 10W adapter and one Apple 5W adapter, or two 10W adapters (I don't see the point of buying the 5W adapters since they are the and the 10W can do everything the 5W can do, it's just a tiny bit larger.) Then you should be able to charge 5 or 6 devices a night with no problems. No, in fact most devices won't charge at all unless the hub is connected to a USB host. When a USB device is plugged in it first determines if it's plugging into a USB host or hub, or if it's plugging into a charging device. This is signaled by the state of the data lines on the USB port. If it's plugged into a charging device, it simply starts charging. Again, the state of the data lines tells it enough about the charger so it knows how much current it can pull - this is how an iPad knows it's plugged into an iPhone/iPod charger and charges more slowly.
The data line state is a key that says, 'This charger only supports 1A.' If it's plugged into a USB host or hub, then it has to talk to the host device (usually a computer, or a computer through the hub) and request power. The hub or computer might only be able to supply 100mA, or 500mA, or on newer USB ports 1A or 2A. The key point, however, is that the device has to talk to the computer and get permission to use that power. The hub cannot give permission, it simply passes the request along to the computer.
So if you don't plug the hub into a computer then nothing attached to the hub will be able to receive permission. The hub doesn't match the state of the data lines of a charger you might plug it into, so nothing attached to a hub that's attached to a charger will ever get permission to charge, or will ever think that the hub is a charger. There are devices which disobey the USB specification and attempt to charge anyway, and they might be able to charge under such an arrangement. Apple devices, however, will never charge unless attached to a charger that follows Apple's charging spec, or a computer with sufficient current output. There are a number of multiport chargers available now, though.
Google for 'usb 4 port charger' and you'll find many inexpensive options that will work with Apple devices, and be more compact than a charger and USB hub anyway.
Ads by Google Are you one of those people who are constantly charging their iPhone or other gadgets. Well, you are not alone. I own an iPhone, a Mac, an iPad, an Apple Watch, a Kindle, a Windows laptop, and a Samsung Galaxy smartphone. And you know what! Charging all these devices is such a pain.
There are wires dangling from wall outlets, chargers on every desk in the room and I’ find myself constantly pulling and tugging these devices, all of the time. It can get pretty exasperating, can’t it? Nomad, makers of some pretty cool accessories for Apple devices have launched a Qi-enabled Wireless Charging Hub that’s designed to help people like me! Here’s more on the device that every modern home needs. Ads by Google Why Get the Nomad Wireless Charging Hub?

And you can take your pick from a number of Qi-enabled wireless chargers in the market, particularly the, which offers fast charging. Nomad now joins the ranks of Belkin in delivering a wireless hub that also supports fast charging for iPhones.
This wireless charging hub can charge 5 devices at one time. The iPhone, of course, plus 4 extra ports for wired charging of your headphones, iPad, bike lights, and Power Bank, all at the same time. The Hub is sophisticated looking, yet discreetly hiding 4 USB ports and a cable routing area under the hood. This means you have a nice cable management solution that keeps unwanted cable clutter off the desk or bedside. The hub has molded steel bars and a rubber base around the bottom to hold it in place on the desk or bedside.
LED lights at the top rim of the Hub display the status of the charging device. They are orange when charging and white when fully charged.

Now, I know that not everyone is a fan of these LED lights blinking bright and shiny when you turn off the lights and hit the bed. Nomad has added a nice touch by adding an ambient light sensor. This automatically dims the lights in a dark room. So the lights don’t disturb you anymore and you can still see if your devices have charged from across the room.

All the ports on the Hub are designed to allow for the optimum charge for each type of device. So while the wireless top port has a maximum output of 7.5W, the rest have output levels mentioned below. 7.5W Max Output: Wireless top 3.0A Max Output: USB C Port 2.1A output, for fast charging another phone or iPad: USB A Port USB A Ports – 2X 1A outputs, for Airpods, Apple Watch, bike lights, or other USB charging devices. Now the USB-A port may not charge your iPad as quickly as it charges another device using the USB-C port, but the charge nevertheless flows to all devices at the same time.
Also Read: Pricing Nomad’s Wireless Charging Hub is priced at just $79.99. Most of the top wireless chargers fall in the $50 to $100 price range but you don’t get as many extra ports as the Nomad. If you’re in the market for a wireless charger, the Nomad Wireless Charging Hub is one you absolutely must consider. You get fast charging, multiple device charging option and even get to keep all those messy cables at bay. The Nomad’s Wireless Charging Hub is (.affiliate link) for $79.99.
