The Energy Device, from KK Energy, features a 850mah battery capable of fast charging very rapidly via USB-Type C port.  The Energy Disposable also has adjustable airflow (valve located on the bottom), a 1.2 ohm Mesh coil, 5% Salt Nicotine, and huge 12ml capacity.   The packaging states designed in the USA, but in all of Asias' infinite wisdom, they chose to name this product quite simply:  KK Energy Disposable Device.  However, they did check all the boxes by making it with a mesh coil, rechargeable, airflow adjustable, great flavors, and a very reasonable price point.  The Energy device also has a unique shape in that it's rectangular but with rounded corners so it's comfortable to hold but won't roll away when set down.
