Dp2 Merrill with powerbank
Now i have no more powerproblems at all! This is a cheap 8000mAh Powerbank with an usb to power ac (3,4mm)
cabel, and of course the Sigma SAC-5 AC adapter. All in all it was €60.- and i get easy 400 shots with this combo! If you need power, i can just recommend this way instead of buy tons of batteries!
