I play a lot of golf and then spend some time at the club house and got tired of dealing w the batteries on my 808 setup. Some last longer than others. Since I'm always in a golf cart when I play, I started looking for a battery w usb connector so I could use my pass through, which I prefer over the batteries. I found this one:
Amazon.com: i.Sound Portable Power Max 8,000 mAh for iPod, iPad, iPad2, iPhone, Droid, and Blackberry: MP3 Players & Accessories
I actually got the larger isound portable power unit and this has worked out great! Stick the battery in the parcel shelf on the cart or just lay it on the bar and vape away w/o any battery worries. A charge lasts for days and it has the advantage that I can use it to charge my iphone if needed or any other usb chargable device. I take a bit of ribbing from my partners and it generates a lot of questions but it works for me....I just tell them its a hookah! Thought I'd share this fwiw.
