Let me put it this way. Three of those itty-bitty 50000 mah 5-volt battery packs in series means FIFTY AMP HOURS of capacity at 15 volts.
Now, as Jim Varney coined...
"Do I look like I got the word stoooopid written all across my face?"
Eleven 10K mah batteries would supposedly be the eqvt the of a 10 amp hour NICKEL METAL HYDRIDE battery. Duplicate that feat ten more times and you have a hundred amp hour Nickel Metal Hydride battery. Ooooooooo, they cost like eleven bucks a pop. Times a hundred and ten. Ooooooooo ain't cheap. Ooooooooo ain't small.
But
It's honest
When something defies common sense it's a con job.
