Is there a Lightning splitter to allow for multiple accessories?

The Belkkin Rockstar is OK. Its cable is quite stiff and I've heard can lose connection but I've had it six months and use it daily without problem. Just don't bend it much.

Okay, I understand your setup now. None of those things would use Lightning. You would want them all to use Bluetooth. Bluetooth is a very low-power system. It's designed on purpose for small devices with batteries in and a lot of its cleverness is its ability to listen for and broadcast using a tiny little chipset and very little battery power. So it's very good at transmitting a lot of very short messages like "they pressed the 't' key" or "your current GPS position is 1234,5678".

Lightning/Thunderbolt is a very high-power system. It's designed for transmitting huge amounts of data very fast. So it can do things like "Here is a frame for a 2048 x 768 display at 768 bits of colour per pixel" or "Here is the next 4 megabytes of your file". But to do this it uses some big chips on the circuit board, requires some very expensive cables, and uses power like you wouldn't believe, even for one tiny message. It would be a complete waste to have a Lightning keyboard, for example.

So don't worry about using Lightning for small devices which don't transmit much data, or that need to be light enough to clip to your ear.

It is now 31/2 years since this thread began, and I still don't see a lightning power/sync splitter adapter on the market. I define that as an adapter with one lightning plug and two lightning jacks. It plugs into an iPhone, iPad or iPod. One jack accepts power from a USB charger, and the other connects to lightning devices or a sync cable.

Apple recently released an adapter that looks exactly the above product. It plugs into an iDevice and has two lightning jacks. It allows you to plug in your charge cable and connect a pair of lightning headphones! And thats it!

I saw it on the Apple Store, and thought I would take a chance that if it could output lightning audio, it might allow for a full connection with my iRig keyboard, my iCirround memory stick and my sync cable. I ordered one. Nope. the output jack only does audio. Hard to believe.

Did you ever find a solution to your multiple lightning connector problem? I have a similar problem in that I want to be able to hook up power and data device to my iPhone 6 at the same time. That is not possible, obviously, with only one lightning connector.

Gyro, yes, the Belkin rockstar does some of what I wanted to, but what I really wanted to do is be able to hook up data devices to my iPhone. The Belkin rockstar specifically says that it does not do that. So, the Belkin rockstar is out of the picture.

Lightning is a daisy-chain protocol, like FireWire, not a hub protocol like USB.

Every Lightning device except the really tiny ones should have two Lightning ports. Just connect them all in one long line.

Have you found a solution to this problem yet? I am in the same boat! I'd like to charge an iPad while using a keyboard that is not on batteries.

The other possibility is that you could use the lightning cable for charging the iPad and then just find a bluetooth keyboard you can plug in for a constant charge.

That looks like a good product, but it's not exactly what I was looking for. I'd like to have my iPad mounted in my car. I want it connected to a keyboard and my radio (will charge connected). I also don't know what case I'll have on it, so I don't think it will be dock friendly.

Keyboards for iPads talk to the iPad over Bluetooth. They would not use Lightning at all. A Bluetooth keyboard would have a battery in and that battery would last for many months because the keyboard would use almost no power. So you need not be concerned about powering the keyboard.

What I'm trying to accomplish is meant to be a permanent location. I'd rather not have to think about batteries in the future at all if I can help it. I would most likely forget about it. If I can find a bluetooth keyboard that allows it to be plugged into a power source, I would be happy. I don't mind using bluetooth over a wired connection. However, I'm a little concerned an iPad might not be able to handle 3 simultaneous connections. Keyboard, external GPS, bluetooth data network. I understand the iPad can do a keyboard and a JawBone speaker, but I haven't been able to test one out with the other devices I wish to use.

Do you know how many devices an iPad can pair via bluetooth at the same time? Obviously each one is unique. I'm not trying to pair 2 different bluetooth speakers, etc. I know that won't work.

Do you have any recommendations for a bluetooth keyboard that isn't a dock? Preferably one that can be plugged in for charging the keyboard.

Look at Logitech Ultra thin keyboard cover (not folio), you can pair it to the ipad, still use bluettooth for the music as well and you can connect its micro usb power connection to a car power adapter usb. I have a double usb adapter in my car and can charge two USB items such as the ipad and iphone oer keyboard simultaneously.

This keyboard works very well, I leave mine plugged in while at my desk but can take it with me to meetings, travel etc.
