I have the Onda V116W Bay trail version.
When in use, the battery does not charge. It slowly drains like 1% per 15 min, even with 2.5A chargers.
So I am wondering, is it OK to use both the DC port and micro USB port to charge simultaneously?
I am trying it right now, it works, the battery level is definitely going up – However, I am afraid that smoke might come out etc.
Can someone tell me if this is a viable and SAFE solution to the slow charging problem??

Check for your MicroUSB cable gauge. You should have at least 24 AWG to get enough current (smaller is better). If you use a 28 AWG you will get small current, even with a 2,4 Amps charger.

Interesting. I’ll try diff cables and report back.
On the other hand, using both DC & USB ports seem to charge much quicker – no overheat yet. I am only afraid of the tablet dying on me…March 6, 2016 at 10:53 pm #28242
Yeah, the cable matters. Using 22awg short cable worked out.
Simultaneous charging via two ports is definitely dangerous. This article explains it: http://electronics.stackexchange.com/questions/187489/usb-power-in-parallel-increasing-the-maximum-current-using-a-y-splitter-ideapoJanuary 10, 2017 at 5:07 pm #60230Rica IiiParticipant

Hi…i am a new user here. The same issue happened to me also. So as per my knowledge you should check for your MicroUSB cable gauge. You should have at least 24 AWG to get enough current . If you use a 28 AWG you will get small current, even with a 2,4 Amps charger.September 1, 2017 at 6:03 am #71284
