Hi vaping friends , just receive a couple of KR808D-1 batt.+ PCC and have some cartomisers at home but doesn´t seems to work very well , what are the best cartomisers I can buy for this model ? can I compare this e-cig to a joye 510 ? because joye 510 works very well with boge cartomisers and I love it but was expecting a bit more for this KR808D-1 , another final question , can I charge the pcc and one battery at the same time at home ? thank you
