I believe there is a defect in the charging software or hardware. I used several iPad 2 car chargers rated for at least 10 watts. (5.2Volts x 2Amps) They take 5x longer to charge than the iPad. Talk about proprietary hardware/software.

The OEM charger EP-TA10JBE is rated at 5.3Volts x 2Amps. The voltage loss in the 4Ft cable supplied must be at least .1 volts, so I do not understand that the voltage difference should cause the charging rate to slow to a trickle.

I'm going to try this.
I'm having the same problem and I read the following in another thread. I'll let you know if it works for me. My charging time is not quite as slow as yours, but it's still slower than it was when I first opened the box and I've only had it less than 2 weeks.

"had the same problem after updating to 4.4.2. It only charged when off. When the device was on, it mentioned 'not charging' in the battery status, but in fact it did charge very slowly when the device was not in use, about 5% per hour.
Also when used, the battery was draining more quickly than before the upgrade.

This solved it for me:
- reboot in recovery mode (hold volume up, button and power while booting)
- clear cache partition
- reboot.

Looks like something in the cache is causing the system to consume (almost) more power than is supplied by the adapter..."

Working better
After clearing the system cache, the charge speed went up to about 22% per hour with the tablet shut off. Seems to be huge improvement in my case. I used the cable that came in the box with tablet.

The standard note 12.2 charger: EP-TA10JWS, The output is rated for 5.3V and 2.0A.

My Galaxy Note Edge has fast charging and regular charging capability. 2 outputs; 9.0V - 1.67A or 5.0V - 2.0A

Has anyone tried this/a fast charger with the note 12.2 ? Will it work ?

Probably not as it doesn't have the fast charging capability, but worth asking the tech savvy people out there.

Besides for travelling purposes it would be great just to carry one charger instead of 2.

Correct it will not fast charge, it needs both the fast charging supporting device and charger to work.

Did you mean, "will not"?

Dont forget it has a 9500mAh battery. The Note 3 has 3200mAh and charges from 0 to 100 in 90 minutes. So you'll always be looking at at least 4-5 hours.

If you leave your connections(Wifi, gps, mobile data, etx), sync and apps running, don't complain that it takes ages to charge.

Fast Charge pre-S6 is Qualcomm tech. The new Exynos chips support their own Fast Charge, but that doesn't apply to the old Exynos devices.

The Snapdragon NotePro's have Qualcomm Fast charge. (Which is not the same as the one in the S6)

The Exynos devices do not. So the P900 will always be slower in charging than the P905.

If you have a p900 and it's slow to charge, that's why.

I tried mine with a 15V charger from my TF700T, and it didn't make any difference.

You can use the Note Edge charger, it also supplies normal levels for ordinary charging. I often use my Note 3 charger.
