Acesori 10400 mAh Aluminum Power Banks

Anyone familiar with this company? I’ve seen other woods with them, but can’t find info about quality reviews, location, etc.

Anyone have experience with this type powerbank, or this particular one? Does it hold enough power for a couple days of recharges, or is there a bigger device of equal value, rather than buying two of these. Price seems too good to be reliable.

Considering something like this for the many times we have power outages due to storms along Georgia/South Carolina Coast.

I am new to this concept and need iPhone cell access at all times due to physical challenges. Any help is much appreciated!

Hmm… over the internet find this: 10400mah Acesori Usb Portable Battery Aluminum Blue Lg Powered Multi
