I am buidling a portable media center and before I put down cash on the final parts I was hoping for some advise.
A lil info:
power source is a 7300Mah 2.1A 5v battery pack
tp-link wn722n wifi adapter
openelec running with the wifi card in AP mode
Im looking to start adding storage to this device approx 250-500 gig (more is always better) All usb attachments run from the Pi itself.
I can pull the amperage of the above hardware so that's not the problem, the storage media is.
Assuming I can use a 2.5 usbhdd (haven't tried yet) I know I can get anywhere from 250 gig to 2 tb
with a pull of approx 500MA but its a bit larger physically than i'd prefer.
So I was thinking of using a non powered hub with USB flash drives or converters with sd cards. I can't really figure out the power pull of these things. I know power per MB the USB drive will be cheaper but I'm not sure its the best option If I would need to split USB cables to get power seperately from my battery(or if my charger even supports 2 devices at once)
Any idea power usage wise or maybe a option I haven't thought of yet?
Thanx a lot
