Keystone Geek Cyber Tank 40K 50mg

The Keystone Cyber Tank 40K is one of the largest single-use disposables ADVapes sells: rated 40,000 puffs, 50mg nicotine salt, rechargeable over USB-C, with a display for battery and liquid, at R320. It sits at the very top of the disposable market alongside the Bro Vapes Hookah 40K and above the OXBAR G Prime 25K. ADVapes lists around 25 Cyber Tank flavours.

What 40K buys you. The rated puff count is the manufacturer’s machine estimate; real draws are longer, so expect fewer, but a 40K device holds a very large liquid reservoir and a battery sized to get through it. The screen matters on a device this size, since you will use it for weeks and want to know when it is running low. Check the product page for the liquid volume in millilitres, which is the honest comparison against other disposables.

Strength. Every Cyber Tank is 50mg nicotine salt. That is a specification of the product, not a recommendation. It is the highest strength sold, matched to the device’s draw, and a 40K device is a very long commitment to one strength and one flavour. If you are unsure about 50mg, a smaller disposable or a pod system with a 20mg option is the lower-risk way to find out.

Cost per puff. R320 over 40,000 rated puffs is about 0.8 cents per puff, the lowest of any single-use device on the site and level with the big closed-pod systems. If you are certain of the flavour and strength, this is the cheapest way to buy disposable convenience.
