http://www.kraveit.com/ The rechargeable is the same size as the NJOY King. I liked it very much and then the carts sent became bad. This is a new style so I will give it a shot when available. They are also going to be offering a 5 pack disposable for $20. That's $10.00 less then NJOY King 5 pack but only 18mg. Just a heads up and dear mods, please remove if not permitted.
