STLTH 8K Pro

Every STLTH 8K Pro disposable we carry is listed at 20 mg/mL and $29.99, so the choice here comes down to flavour. There are 15+ listings, mostly iced fruit, plus mint and tobacco options. STLTH rates the device for up to 8,000 puffs from 14 mL of e-liquid and lists a rechargeable 800 mAh battery. The device is finished when the e-liquid runs out, not when the battery goes flat.

What STLTH lists for the 8K Pro

In its product overview, STLTH describes the 8K Pro as a disposable that holds 14 mL of e-liquid and is rated for up to 8,000 puffs. STLTH lists one nicotine strength, 20 mg/mL. The internal 800 mAh battery is rechargeable. The LED screen shows the remaining charge as a percentage, and a drop icon on the same screen shows the e-liquid level.

STLTH's user manual gives the device size as 45.8 x 84.0 x 26.2 mm and says it is made in China. To use it, the manual says to remove the silicone cover from the mouthpiece and inhale. The device then produces vapour, and the screen shows the battery and e-liquid levels.

The manual lists these built-in protections:

• a 7-second puff time-out: the screen shows an indicator and then turns off if you inhale continuously for more than 7 seconds
• short-circuit protection, which shuts the device down automatically
• overcurrent and overvoltage protection

Recharge or replace: reading the two indicators

The battery and the e-liquid run out separately. The battery is rechargeable, but the 14 mL of e-liquid isn't meant to be refilled. A flat battery means you charge the device, and an empty e-liquid indicator means you replace it.

The manual gives a separate signal for each. When the battery reaches 0%, recharge the device. While it charges, the screen shows the battery level, and it turns off once the battery is full. The e-liquid indicator changes colour as the e-liquid goes down, and when it flashes red, the device is fully used and can be disposed of.

For best performance, STLTH recommends that you stop vaping and dispose of the device once the e-liquid indicator turns solid red. The 8K Pro is designed for single use. The manual says not to try to refill it, and it warns that opening it causes permanent damage and may be dangerous to the user. When the device is used up, the manual says electronics and batteries don't belong in household waste. Take them to a separate collection point for recovery and recycling.

Charging and handling, per STLTH's manual

The 8K Pro runs on a sealed lithium-ion battery, and STLTH's manual gives specific charging instructions:

• Charge only indoors, never in a vehicle.
• Never leave the device unattended while it charges.
• Don't vape while it is charging.
• Connect it only to a safety extra-low voltage (SELV) circuit rated at 5V DC, 800 mA or more. SELV refers to a power supply designed to keep its output at a low voltage.

For handling, the manual says to keep the device away from high heat, such as a car interior, radiators or fireplaces. Keep it dry and away from water and other liquids, and don't store it near metal objects such as keys, jewellery or coins. The manual also says to vape it only upright. It adds that short breaks between puffs improve flavour and prevent dry hits.

Citrus and other iced fruit listings

Most of the STLTH 8K Pro listings we carry are iced fruit. If you're weighing this line against other formats, our disposable vapes page shows the wider range.

Citrus-led iced listings

Lemon Squeeze Ice and Citrus Burst Ice put citrus at the front with ice. Strawberry Lime Ice adds strawberry to the lime, so it's the choice in this group if you want citrus alongside another fruit.

Other iced fruit

Each of these has ice added. The fruits in each name are:

• Lychee Melon Ice: lychee and melon
• Kiwi Dragon Berry Ice: kiwi, dragon fruit and berry
• Cherry Grape Ice: cherry and grape
• Green Apple Ice: green apple
• Juicy Peach Ice: peach

To compare these with other lines, see our iced flavours and fruit flavours pages.

Peach with or without ice, plus mint and tobacco

Juicy Peach and Juicy Peach Ice give you the same fruit with and without ice. If you're deciding whether you want the cooling element at all, this pair lets you compare that directly within our 8K Pro range.

The mint listings include Ice Mint and Arctic Mint. You'll find more on our menthol flavours page. Rich Tobacco is the tobacco option, for anyone who doesn't want fruit. Our tobacco flavours page has more.
