This is great solution for zoom f8 using external battery.
With this Anker PowerCore 10000 mobile battery (10000mAh, full charged) and LANMU’s 5v to 12v usb to dc connector, Zoom f8 could run 8 hours ( 11.7~6v continuously ) with 8 tracks phantom on.
That means with internal battery I can go a day which is good enough for field recording as I just need to power up zoom f8 right before hit rec. If you are location sound guy, you can go for more powerful mobile battery.
Size of this mobile battery is 92 × 60 × 22(mm) and Weight 180g, so much smaller and lighter than carrying extra AA batteries and much nice to walk around with full of gears!
And importantly, usb mobile batteries are affordable and convenient, so I don’t think I need to invest on Np1 or sony’s batteries anymore!^^!
Thanx to Saturday Sound Guy for great introduction.
