I currently own 3 power banks ...
Funny thing about power banks :
A) They are usually over rated ( some times horrendously so )
B) capacity is measured by what goes in - not what come out
C) so if you wan't 10,000mAh to your device , you will need to buy a 20,000mAh power bank
D) You can only pack so much mAh into so much space ( related to that over rated capacity )

Link is to my website , and the last powerbank test .. ( So if you thought cams can be bad )
I wanted a solar powerbank to run a cam ( Possibly my G90 ) in conjunction with DC ..
Plan was to run a PB ( power bank ) to the cam , DC to the cam as well as solar ( I have a USB solar panel that works )
So when the DC is turned off , the powerbank takes over ..
Plan was to run DC to the PB , as well as solar with a split USB cable ..
So when DC is off , solar is still trickling into the PB ..
If the PB is large enough it should run all night without problems ...
And when DC comes back on it recharges the PB ( ?? ) how long is your drive ?
PB's can take a long time to charge ...
So maybe at night you may need to plug in a 2nd PB to feed the first one and maintain charge ?
( Yeah , its getting messy )
