A Hidden Feature of iBasso R10 / DX100:
I did an experiment with a portable battery that I have purchased for 39 dollars on Amazon.com. I found that R10 and DX100 can run with an external battery power via USB. (There's no portable battery with V5 cord out there)
Connect any of your portable battery with USB to R10 / DX100's android USB port. It won't show the charging mark. Instead, It will run on that external battery! R10 / DX100 will not use its internal battery till it completely drains the external battery.
That's right! you can increase your R10 and DX100's battery life by 30 hours or more through this way.
I have tested this outside today. It works flawlessly. There's no heat, error, etc.
You'll have to plug in your external battery before turning on your R10 / DX100. Once you do that, R10 will automatically turn on and recognize your external battery as its main power source!
FYI, Here I confirm that 256GB SD card in FAT32 format with SD to micro SD adapter work flawlessly with R10 / DX100. You can increase your R10's capacity up to 310GB!
I encourage moderator to add this to a main thread. This feature wasn't mentioned in R10 / DX100's manual.
