The Genie Air 5000 is not a rechargeable device, though there is a new larger size that is rechargeable, however the MSRP on that is over $50. Despite lacking the charging feature, it makes up for that in flavour and quality, we've personally gotten many days of use out of one device, the only dropoff was once the device was completely dead.
The Genie Air uses a synthetic nicotine in their disposable. Synthetic nicotine is meant to deliver a stronger nicotine hit compared to its salt nicotine counterpart.
My personal favourite of the Genie Air would be the Peach Blueberry Frost. Featuring a delicious mix of peaches and blueberries with a soft menthol finish.
Mesh coils are designed to improve vapor production and flavour. They may also last longer than a traditional wrapped coil as there are no 'hot spots', meaning your coil should heat evenly with every draw.
