Wow, another useless gadget that has gathered over $80,000 in funding! Never ceases to amaze me!
Having an external charging battery pack is nice. But to make it into the form-factor of a wallet with a solar panel attached is complete stupidity. For one, the amount of piss-ant charging you will get from that solar panel is nothing compared to what you need to charge up that battery. It is just a gimmick! You will almost inevitably be plugging your "smart" wallet into the wall at night to charge the internal battery. Second, having all your money and credit cards also in there and having to pull it out of your pocket every time is also idiotic, as has already been mentioned several times (risk of losing it, theft, etc).
And to charge people $99 for this garbage? Future price to be $199? Seriously? WTF?
This is what I use for all my phone battery-life extension needs and it does the job beautifully, at a fraction of the cost, and with the ability to change the battery. You don't even need a BlackBerry phone. And you can buy a bunch of LS1 batteries for nothing and extend yourself even more if needed, just swap in and out.
I love this thing!: https://www.amazon.ca/BlackBerry-Battery-Charger-Bundle-Z10/dp/B00BMMQFBI/ref=sr_1_fkmr0_4?ie=UTF8&qid=1493158311&sr=8-4-fkmr0&keywords=blackberry+portable+charger+ls1Basically, this portable thin charger/battery pack has a USB port to let you charge that LS-1 battery inside of it. It is thin enough that you can strap it to the back of your phone case. The device also has a small USB cable connected to it that you can plug into your phone when you want to charge it from the LS1 battery in the charger. Alternatively, you can do a complete battery swap if your phone also happens to use LS1 batteries.
The nice thing is, this device allows for daisy-chaining or "pass-through" charging. So if I want to charge BOTH the external LS1 battery in the thin charger, *and* the battery in my phone, I can plug USB into the charger while it is hooked up to my phone with it's own little USB cable. Both the internal phone battery and the external LS1 battery in the charger get filled to capacity. When I am done, I unplug and leave home and I've got enough to last me well beyond my needs!
