I have a Fire HD 8 and I've connected a charge+OTG cable that I've confirmed works to charge and mount OTG devices on my Nexus 7 (2013) tablet. However, on my Fire HD 8, only the OTG device is mounted, the Fire is not charging with this setup.

Could it be the cable is not compatible with the Fire HD or could it be the Fire HD is not capable of OTG+Charge without a software add-on?

Thanks in advance for the help!

What your device model you're referring?

You can charge it directly to battery using TP4096 charging module.

I’ve looking at doing the same thing, OTG and charge, tried lots of different OTG cables, hubs, hubs with switches but nothing works.
Today I’ve tried wiring in a TP4056 charge board but it’s not charging my battery even though the charge light is on
Can anyone help with this
Red + battery power out
Black - neural power out
White + battery
Green - battery
Could anyone please help with why I can’t change battery, it’s still charging with the original change port but not with the PT charge board
