which carto is more consistant for flavor & vapor & life span, the boge 510 or joye 510 carto? also which is metal like the 510 attys? I have 2 eGo XL cartos & they're plastic (haven't tried them yet...I'm afraid of melting them...from heavy vaping). 1 more question about the eGo PT, I don't have a fast charger for it...I use the usb cable that came with it, should I get a fast charger for it or just stick to the usb charging cable? reason I'm asking is because I'm pretty sure the fast charger has a built in cut off in it where as I'm not sure if the usb cable does (I charge my battery at night before I hit the sack...& just worried if in the long run if the battery will not perform as expected). also I work @ walmart in the electronics dept. & I'm considering getting a 4 port usb wall charger to use with a 10 ft usb extention cable I bought a while back...would this wall charger work with the 10 ft extention & the usb charging cord for my eGo? or does the wall charger have to be one from an online vendor? thank you in advance to any & every ECF vaporite that can point me in the right direction.......& as always keep on vapin' on (DON'T SMOKE THAT .... IS BAD NEWS)
