500000mAh Portable Solar Charger Dual USB Battery Power Bank

... and people buy it like crazy...

all the 100000+ mAh power banks is a scam - first, at what voltage? that's 100Ah... an average car battery has 40-60 AmpHours at 12V ( which translates to X cranking amps... but these power banks the size of an audio casette at 100 Ah ?

After buying, some find out that the packs last for 1-2 hours of charging a smartphone... what a rip-off and scam.

 

and ebay allows to misrepresent these by sellers... that's kinda more than just 'ugly'
