Vaping is more than just a hobby; it’s an investment in a smoke-free lifestyle. However, even the most premium hardware from Vapesourcing requires consistent care to perform at its peak. Improper refilling or neglecting hygiene can lead to the dreaded "burnt taste," leaking tanks, and shortened battery life.

In this comprehensive guide, we will walk you through the essential steps for vape maintenance and effective refilling techniques to ensure every puff is as flavorful as the first.
1. How to Refill Your Vape Tank Without Leaking
The most common issue vapers face is leaking immediately after a refill. To prevent this, you must understand the physics of your device and maintain the internal vacuum seal.
- Prime the Coil: Before filling a new tank, drip 3-5 drops of e-liquid directly onto the cotton of the coil. This prevents "dry hits" and immediate burning.
- The 90% Rule: Never fill your tank to the absolute brim. Leaving a small air pocket helps maintain the vacuum pressure, which prevents juice from flowing out of the airflow holes.
- Close Airflow: Always close the airflow control ring before opening the top cap to refill to minimize pressure changes.
2. Featured Performance Hardware: Geekvape Aegis Legend 5

- IP69K Tri-Proof: The most rugged rating in the industry, making the Legend 5 resistant to high-pressure steam and extreme drops.
3. Advanced Coil Longevity and Maintenance
The coil is the heart of your device. Industry data suggests a well-maintained coil can last up to two weeks, whereas a neglected one may burn out in 48 hours.
- Avoid Chain Vaping: Giving your wick 15–30 seconds to re-saturate between puffs prevents the cotton from drying out.
- Clean the Connections: Use a Q-tip with a drop of isopropyl alcohol to clean the 510 thread connection. This ensures stable voltage and prevents misfires.
4. Frequently Asked Questions (FAQ)
This usually happens if you didn't "prime" the coil properly or if the AS Chip 5.0 detection suggests the cotton is too dry for your selected wattage.
We recommend a deep clean with warm water every time you switch flavors to prevent residue buildup and preserve the clarity of the premium Geekvape coils.
While rinsing is possible, it rarely restores original flavor. For the best experience with the Legend 5, replace the coil once the flavor begins to fade.
Slight warmth is normal. If it is too hot to touch, unplug it immediately. Always use high-quality external batteries from Vapesourcing.
Signs include diminished vapor production, a persistent burnt aftertaste, or the Legend 5 smart screen showing inconsistent resistance.
