Portable Power Solution

Ok, I am sure this has been discussed, but it is so hard to find anything in this forum.
I have 2 back to back aerial jobs on Saturday and need to charge my batteries as soon as I am done flying each one.
Will this work?

????

Profits from these jobs will be buying more batteries, I just don't have time to get more before Saturday and 3 are not enough.
Cheers,

Peter

Not to burst ones bubbles, but any power source I used I would make sure it has a sine wave inverter, and not digital one. Makes a difference with delicate electronics.
