Immediate troubleshooting for the JNR Tank Pro 33K Puffs

Before contacting customer service, start by identifying the exact symptom.

Common issues and solutions

No draw from the first use
➡️ Possible cause : protections still in place or sensor not activated
✔️ Solution : remove all stickers and silicone tips. Then take 2 to 3 firm puffs to activate the automatic sensor.

Very difficult draw despite the light being on
➡️ Possible cause : condensation of e-liquid blocking the airflow
✔️ Solution : gently insert a toothpick into the tip to clear the passage, without forcing.

The LED blinks but no vapor comes out
➡️ Possible cause : low or empty battery
✔️ Solution : recharge the device for 30 minutes via a low voltage USB port (computer recommended).
❌ Avoid high-power wall chargers.

Optimizing performance and longevity

Le JNR Tank Pro 33K Puffs is designed to provide extended battery life, provided you adopt the right habits.

Burnt taste: what to do?

A burnt taste indicates that the internal wick is dry. This can happen if:

• you chain too many puffs without a break

• or if the e-liquid is completely consumed.

👉 Tip : space your inhalations 15 to 30 seconds apart.
If the taste persists, the tank is likely empty and the device needs to be replaced.

How to extend the life of your disposable vape

Here are some simple yet effective habits:

• Moderate inhalations : prefer puffs of 2 to 3 seconds

• Proper storage : keep your vape at room temperature

• Smart recharging : 30 to 60 minutes is sufficient, no need to leave it plugged in all night

When the vapor becomes weak and the flavor disappears, your JNR Tank Pro 33K Puffs is reaching the end of its life.

Safety: recognizing a serious problem

Although rare, some defects require immediate cessation of use.
