I though maybe we the owners of the new ego booster needed a thread to discuss what atties or cartomizers we have used with our boosters and what not to use . I will start . I used an ego mega atomizer type B with a filler cartridge in it . 2 ohm . It wore my 1000 mah batteries down in 3 to 4 hours . Now the ego mega ( some times called the XL ) atomizer type B is one of my favourers and you can buy them on Jack's site . They really don't need boosting and work good but some of the claims I have heard about the booster are that even at full boost your supposed to only loose 25% vaping time on the batteries . I have tried the booster on an echo bottom coil cartomizer and I can say it works very well . I also tried it on a new G4 and it works pretty good on those . So what have you used and how did the booster do with it .
