Somewhere between fifteen and twenty thousand honest draws; five to eight weeks for most users. At that duration the pod-swap models earn their keep, because you replace the liquid supply two or three times before the battery shows any age.
Chunkier than a 10K, but the difference is smaller than the numbers suggest; reservoir liquid is dense and batteries are modest since they recharge. The Nera30K still fits a jeans pocket. Nothing here needs a bag.
Per puff it is the best prefilled value we sell: £9 to £13 for a device that replaces a month and a half of disposables. Only bottled e-liquid through a refillable kit beats it, and not by the margin you might expect.
