? There should be no difference between charging one vs the other.

Apple products generally use more than 500 ma. Most newer usb chargers are 1 amp, but the old stuff is often clipped at 500ma. Forget about an iPad, it wants more as does an iPhone.

Apple charge

I ran into this issue a few years ago when making a portable USB charger for my android phone. Android does not have that issue, but when researching to build this is where I came up on it.
Check the voltage on the data pins (2 in the center of the USB) as explained below.

https://learn.adafruit.com/minty-boost/icharging

Excerpt from the article as to why:

We did some experimenting (see the video up top) and determined that in fact the different voltages/resistances did effect the charging rates! Using the 2.8V&2.0V setup resulted in a 1 Amp charge rate and the 2.0V&2.0V setup resulted in a 500mA charge rate.
This made us very happy, because 500mA is within the capability of the MintyBoost chip. We redesigned the PCB to allow us to have 4 resistors on the datalines and put two 75K and two 49.9K resistors in each kit. So far we have had no problems charging any of the latest Apple devices. Hooray!


I built 2 of these with my son, bought the circuit boards from Adafruit and bought the parts locally or online, depending. Added a solar panel off of a dead yard light to charge in the sun or pull the NiMh AA batteries out and use a wall charger on them.
Now that the price of LiPo (Lithium Polymer) portable chargers is way the hey down I use them and keep this as a backup.

Hope this helps some.

It is just not your Apple products. The chargers that they use are usually only good up to 250mA, therefore will not charge any smart phone, it barely does my Ipod, they are garbage. Buy a new one that is capable of more. Also, this is not just in your Vengeance, many models across the board have the same issue.

my 2016 29udql5 does the same thing
