ECHO are the most popular power electronic cigarettes. Its huge battery capacity combining with the easy-to-fill clearomizer system makes e-smoking an even better experience.
ECHO starter kit is both durable and affordable. A fully charged battery and a fully refilled 1.5ml clearomizer could last for 15-20 hours of heavy smoking. That is equivalent to 3 packs of tobacco cigarettes. And yet both components are reusable! Saving you money on smoking!
Based on ECHO series, this ECHO-USB model is much simple. There is a USB charge port on the bottom of the battery, no need to worry about your ECHO running low on power anymore, just screw out the cap and recharge it.
