Hey guys i just got my 510 USB passthrough in today. Its just the USB to the battery there is no inline battery. Anyways i just plugged it up to the wall through a 5.2V(1000MA) old ipod touch charger and when i dont have the cartomizer on it the color at the end is red like its working and i can hold the button down and it will stay red ... now when i hook the cartomizer to the battery and press the button it goes red for a second then flashes green and it wont heat up or anything
. Is there chance even though it doesnt have a inline battery that you have to charge it ? Anyone know whats going on this my passthrough? im new to the passthroughs so i have no idea thanks to everyone that takes there time to read this !
