This one works great for me with my iPad 2. http://amazon.com/dp/B003GSL6UG
As Bob mentioned make sure your charger is for a Ipad and not for a Iphone or Ipod. Same plug on all of them but different charging outputs. If its for a Ipod it will charge a Ipad but very slowly.

If the brightness is all the way up you will not be able to charge it very fast, if at all. Sometimes it will use battery faster than it will charge. Lower brightness levels allow it to charge much faster, which isn't helpful for day flight. Mine will keep a charge on full bright and maybe lose a few percent on a several hour cross country. If I just turn the screen off/put it in sleep mode it charges back up.
All the chargers I have seen are 2.1 amps max.
Here is one rated at 3 amps, but only on the wall 115 volt input -

No experience with it, but I too was wondering why my Ipad didn't charge while in use...
We need a 3 amp 12 v cig. lighter input device...
New to using the iPad with wingx. I bought a 2.1 amp adapter to charge it from a cigarette lighter plug but while running wingx plugged in it still kills the battery. Is there any way to charge it or at least keep up with the battery use in flight?
For sure, but my lighter is only 10a and I want to have some room left for other things if I need to
What would you need more than 7 amps for in flight?
Hair dryer, shaver? tanning light?.....
This charger will mount in your panel and charge an iPad and iPhone simultaneously.

I read the data sheet to say the 3 amps is the sum of a 2 amp USB port (Ipad) and a 1 amp USB port (phone).
It is the built-in equivalent of the common dual port devices that plug into a cig. socket.

I'm not sure of the definition of "common" as it applies to the devices that plug into a cig. socket. The two voltage pins of the USB port will supply whatever current the load requires up to the wires ability or the fuse or circuit breaker capacity. However the Apple devices that require 5 watts, certain iPhones, or 10 watts, iPads, will only "rapid" charge if they see the proper voltage pair on the data pins. Other tablets like the Samsung Galaxy tablet will only rapid charge if it sees a single voltage on the two data pins tied together. Other tablets, like the new Google Nexus will only charge if it sees the two data pins shorted together. All of the tablets and the iPhone look at the data pins for a certain signal before allowing rapid charging. Some of the devices like the Samsung Galaxy tablet will go into trickle charge mode if it doesn't see the proper voltage. This is to protect the common computer USB port from damage because the port was never designed as a high watt charging station. Therefore, some of the USB charging devices sold at Amazon and auto parts stores will not "rapid" charge Tablets and/or certain phones, and some will.
I bought extended ANKER battery from Amazon and it feeds iPad all day

That would work. Buy a male power outlet plug and with a little solder you'd have a working alternative for <$15
Notice: it can't use for iPhone ,ipod.
That is the case for charging Apple devices. One port conforms to the Apple spec for 10 watt charging, and the other port conforms to the Apple spec for 5 watt charging. This is done by setting two different voltages on the data pins. So for Apple charging the power output capability is at least 3 A, but the charge pump that I use is good for 5 A, and if you plug devices in that only require raw power, the unit is capable of putting out 5 A at 5 Volt. Wanting to build a conservative device, I advertise it as a 3A charger and recommend that you fuse it at no more that 2 A, representing about 25 watts which would still allow you to pull 5 A from the charger, but I don't recommend that.My comment was on the multiple "common" dual port chargers rated at 2.1 amps in one USB port and 1 amp in the other USB port. There are many of them. Even our grocery supermarket sold one...
Reading the specifications of the link you provided seems to say that the "built-in" one has exactly the same current specifications.
Is that not the case?
did you see this in the description? not sure if it's a typo or what.

This one will do the trick.
Don't be so quick to discount your options. I purchased this unit for my iPad 3. I have flown with it on 3 long X-country trips now of 3 hours or more each leg. It keeps the unit charged while in flight without any problems. It is working great for me.Well, guess newer isn't always better. That settles it then.Thanks all
Please let us know how it works. It appears from the last picture of the device that the data pins are soldered together, with the possibility of adding some resistors on the pads labeled R4, R6, R5, R3. However with the data pins soldered together, there is no way to make it work for Apple devices. They need a different voltage on each data pin.Cool! Cheap enough I ordered two for testing. Thanks for the link!
No I didn't, but it would be simple enough to rewire the usb port appropriately.

??? Where would you mount the two resistor ladders needed for Apple devices? Or are you talking about cutting off the USB connector and putting on a new one with the proper circuitry?
In the case of this device, the smarts are in the Magic Cable Duo that fools your high current Apple devices into thinking that they are connected to an Apple charger. There are other companies that make these smart cables that allow any bare USB charger to work with Apple devices and other tablets, http://www.amazon.com/s/ref=nb_sb_noss_1?url=search-alias=mobile&field-keywords=csquid

Well it took a while but the cheap little buggers finally arrived. Not wanting to risk my iPad on an unknown USB charger I first plugged in an old unused MP3 player. All good, charged like a champ. Then I tried my work phone, actually hoping it might get fried . It charged fine as well. Moment of truth - iPad 2. Plugged it in, and viola, after about a one-second delay (perhaps circuitry in the chip distinguishes an iPad somehow and adjusts voltages on the data pins accordingly?) the iPad charges while in use. Exactly what I wanted and for a pittance on ebay. I couldn't be happier.
Here's a pic of Danny and the 'Doll as proof:
I just ordered one of these to use instead of a "cigarette lighter" on the panel.
