I chosen this device for the 1800 mah battery. If would also been performed like a 1800 mah and not 600 mah, it would have been my favorite pod system for the year. With a 5% battery loss every 20 puffs at 18 watts sadly can only enjoy the device about 5 hours. I have never experienced a pod systems being so bad for a 1800 mah. My vaporesso gtx one with 2000 mah battery is amazing. I recharge about every 2 days.

Have you contacted Vaporesso support? I’m sure they would make it right.
