Hey guys I'm looking to buy a glass globe attachment for 510 threading. this is the glass globe: http://www.ruvaped.com/shop/glass-globe-attachment/ Anyways I'm looking for the best battery that can be used for it. I also need it to have USB pass-through. I have an O-phos but I'm kinda new to e-cig batteries so help would be great!! Mainly im wondering what voltage is the best, and what brand(s). would a Ego t passthrough be good?? http://www.gotvapes.com/index.php?main_page=product_info&cPath=104_275_80&products_id=472 it says it has variable voltage, but I need to know if this voltage is too much/too little to power the ceramic nail in the glass globe.
