  1. I will be charging one of the following lol; my S4, Nvidia Shield, Nexus 7, and/or my Galaxy Note 8. I would wear the charging bank out :)

  2. I’ll charge my T-slim insulin pump, dexcom cgm, note 2 and my jbl Bluetooth speaker. All of then need to stay charged.

  3. Gonna charge my LG G2 and Nook HD+. Will be going on a six hour bus trip soon, would be great to have this handy and not have to go scrambling for an outlet.

  4. My Moto X (I play Ingress so I would really get some use out of this thing!), my wife’s iPhone, and a slew of devices I use for development at work; ranging from iPads to older Android phones and even a token Windows Phone.

  5. This would be perfect for my job usually working outside with no power outlet or car to charge up via power socket. For work it would be powering up the Blackberry Bold (I know i know, but it’s for work). But I’ll also use it for my Nexus 5 (my 1st Nexus phone!) and my Nexus 7 while helping out those in need whenever/wherever the occasion may arise.

    For those that haven’t read the review I suggest you do. Great and straight forward.

  6. I’d use it to charge my Evo 3d that I use to view 3d pics i take with my Nikon, an LG G2, my TF700 Infinity and a iPod Touch… everything needs juice lol

  7. I’ll be charging $5 for every 3,000 Coulombs.
    For myself, #1: Google Glass –because the battery life sucks hard.
    #2 NOT the Moto360, because it had better last well over 24-hrs!

  8. I’ll be charging my wife’s HTC One (because she never charges her phone) and my HTC One as well (we have to use mine for everything because hers is always dead).

  9. It would be great. I would be charging my s5 , my s4 backup phone, samsung tablet and my kindle hdx. I wouldn’t use it on my work blackberry because I like it out of juice.

  10. Wow! This will be very helpful to me. I would use it with my note 2, and note 4 (when it comes out) so I don’t have to be with a low battery again.

  11. The sheer joy of just having this around would be Awesome! Of course I would be charging my N7 2013 and Lg G2
    Thnx Android Guys ✌

  12. Would use it to charge my Nexus 5 and iPod touch since Ingress and Brave Frontier suck up all the power :)

  13. I just had my other portable charger stolen so this would be awesome. I work out of town for 2-3 days at a time and I use it to keep my HTC m8 and iPad mini charged.

  14. My Hisence tablet, Bluetooth accessories, daughters Airpad, multiple cellphones, other USB dependent devices.

  15. I’d charge my M8. Coming from a S4 with a ZeroLemon battery. I don’t see how people stand normal batteries. :P

  16. Battery life on my M8 is awesome, but when Ingress is running a battery bank would come in handy.

  17. I’m really impressed with your writing skills and also with the layout
    on your weblog. Is this a paid theme or did you customize it yourself?
    Either way keep up the nice quality writing, it’s rare to
    see a great blog like this one today.

  18. You actually make it seem so easy together with your
    presentation however I to find this topic to be actually one thing
    which I feel I’d by no means understand. It seems too complex and
    extremely vast for me. I’m looking forward in your subsequent
    post, I will try to get the cling of it!
