A SERIES

The OXVA Arbiter, Arbiter Solo, and Arbiter 2 are all vaping devices from OXVA's A series, but they have some key differences in their features and specifications.

 The Arbiter Solo has a 4ml capacity pod, while the Arbiter and Arbiter 2 both have larger 6ml and 5.5ml capacity pods, respectively.

All three devices have a proprietary chipset and support variable wattage, temperature control, and TCR mode, but the Arbiter 2 has a new and improved interface.
