Idea DC-DC converter step up from usual power bank as external battery for nikon DSLR Answered

Can anybody build a circuit to convert the 5v-2.1A to 8.4v-2.5 to be able to power on the DSLR camera

USB output 5V*2.1A=10.5W
Camera input 8.4V*2.5A=21W

The idea inspired from ifootage Electric Ray E1  ,I don't believe in would power on my DSLR nikon D7100 probably, plus it's too expensive for me

Might be a stupid question but do you suggest to find the missing 10.5W?
Last time I checked my electronics skills I failed to generate power sufficiently from thin air ;)
