Geek Bar Pulse X 25000

The Pulse X is the device the rest of the range gets compared to. Two modes sit behind one button: Regular Mode stretches the 18mL reservoir to around 25,000 puffs, while Pulse Mode roughly doubles the wattage for a warmer, denser hit at half the longevity.

What actually makes it worth the money is the airflow dial. Most disposables lock you into one draw; the Pulse X lets you close it down for a cigarette-tight pull or open it up for a loose, cloudy one — and the dual mesh coil holds flavour at either end.

The 1.8" screen isn't decoration either. You get a real e-liquid percentage rather than a guess, a battery gauge, and a mode indicator, so you know exactly when to reorder.
