Is it possible to refill e-liquid or replace the pod?

Vozol is the brand. Neon 800 2.0 is the disposable model available on this page at Elekcig.

The device is activated by inhalation: it starts when you draw through the mouthpiece. No button needs to be pressed.

The nicotine strength is 20 mg/ml, that is 20 milligrams of nicotine per milliliter of e‑liquid. The model contains 2 ml of e‑liquid with nicotine salt.

It is the manufacturer’s estimated puff count. How many puffs a device provides depends on usage; 800 is not a guaranteed number.
