we like to shoot video , lot of video , but as u know single nikon battery is not enough . and buying multiple battery is not a option for us right now .
as we have some usb power bank with us which are 10,000mah each which is 10x times of nikon battery . we though tit will be good idea to find someway to use external usb powerbank in camera .
1. first problem we had was nikon battery output power is 7.95v but usb powerbank output is 5v .
so to solve this problem we got 5v to 9v regulated stepup booster . and we adgusted the output power to 8v .
now we directly connected our 8v into the camera with wire to find out whether is will work or not .
and to our surprise camera turn on , but its show error message to use genuine nikon battery
2. second problem
error mesaage
- this battery cannot be used . choose battery use in this camera .
so we found out that we power camera directly with 8v , since nikon check wheather we are using nikon battery for not .
so to overcome this problem , we got one stupid idea .
we dissembled the only nikon battery we had .
then we conected our power point to the nikon battery circuit .
then we inserted our modded battery into the camera .
camera turn on .
but we got a new error message
- press shutter release button again .
shutter is perfectly fine . we dont know what the problem .
we are stuck here .
do you guys any solution to it .
