Product Summary
Small enough for any pocket, the Smok Gram-25 is a mouth-to-lung vape kit with a 900mAh battery, a 1-25W variable output and a 0.69 inch OLED screen showing battery, resistance and power. It pairs with the 2ml Gram-16 tank and comes with a 0.6 Ohm G16 coil, plus adjustable airflow for tuning the draw. The wide wattage range means the kit can adapt as your vaping habits change rather than needing replacement. Use 50/50 or high PG e-liquids for best results. A neat option for beginners who want screen-level control without bulk.
The Smok Gram-25 is a compact mouth-to-lung vape kit that pairs a 900mAh battery with a small OLED screen and a refillable 2ml tank. Unlike a sealed bar, you choose your own e-liquid, top the tank up from above, and swap the coil when it tires, so one kit keeps going for as long as you look after it. Variable power up to 25W and adjustable airflow let you set the draw, and it charges over USB-C.
Who is the Smok Gram-25 for?
Choose it if:
- You are starting out and want a screen and adjustable power without a bulky mod; it is a neat step into refillable vape kits.
- You want a tight mouth-to-lung draw you can fine-tune with airflow and wattage.
- You plan to run 50/50 or high-PG liquids, including nicotine salt, and refill from a bottle.
Look elsewhere if:
- You never want to handle e-liquid or change coils; a prefilled pod kit removes both jobs.
- You are chasing big sub-ohm clouds; this is a low-power MTL kit, so a higher-powered device does more.
Tank and coils
The Gram-25 uses the 2ml Gram-16 tank, filled from the top so you do not have to take it off the mod. It runs Smok's G16 coils, and a 0.6 ohm dual coil comes fitted for a warm, flavourful draw, with a spare in the box. When the flavour drops off or the coil starts to taste burnt, screw in a fresh one rather than replacing the whole kit. The tank takes standard 510 drip tips, and one is supplied, so you can change the mouthpiece to suit.
Battery and charging
Inside is a 900mAh battery, charged over USB-C at 5V/2A, which covers a day of light to moderate mouth-to-lung use for most people. The 0.69 inch OLED screen shows battery, coil resistance and wattage, so you can see when to plug in rather than guess. Any standard USB-C cable tops it up, and the one supplied in the box gets you started.
How to set up
- Charge the kit over USB-C before the first vape.
- Fill the Gram-16 tank from the top with 50/50 or high-PG e-liquid, then leave the coil to soak for a few minutes.
- Set the wattage on the screen and open or close the airflow to taste.
- Draw on the mouthpiece to vape.
- When the flavour fades, fit a fresh G16 coil and refill.

Because you refill the Gram-16 tank from a bottle and recharge over USB-C, the Gram-25 is a proper reusable kit, a world away from the throwaway bars withdrawn from UK sale in June 2025. Keep it clean, change the coil when it fades, and it will serve well past a single tank of e-liquid. As with all nicotine products, it is for adults aged 18 or over.
