One of its biggest differences from the Armour G2 is the battery setup. The GS2 uses a replaceable 18650 battery (sold separately) and supports adjustable output from 5W to 80W. That gives you more flexibility if you prefer carrying a spare battery instead of waiting for the device to recharge.
It also comes with a 5ml Armour G Series pod, a 0.96-inch TFT screen, and USB-C charging. The kit includes a 0.3Ω dual mesh coil pre-installed and a 0.15Ω dual mesh coil in the box. It supports different GTX coil options, so there's room to experiment with vapor production and flavor.
I also like that Vaporesso includes a button lock and auto-lock feature, plus top filling and top airflow designed to reduce leaks. Pulse Mode is another useful feature for keeping output more consistent as you vape.
For me, the main question is whether the external-battery design is worth it compared with the Armour G2's built-in battery. Would you pick the Armour GS2 for its 80W output and replaceable battery, or go with the G2 for its built-in 3400mAh battery and faster charging?
