The Kanger UBOAT is a refillable pod system that is a great alternative to the JUUL. It features a 550mah built in battery. It uses a ceramic 1.5 ohm coil for great flavor production. The refillable pod holds 2ml of juice. The design is inspired by a submarine and is very sleek looking. Automatic puff sensor.
Being a closed system, it is designed for use with nic salt, but can also be used with regular e-liquid.
