-
Inspect it like a pro
-
Avoid scams when buying secondhand

Let’s dive in!
Section 1: How to Inspect a Used Vape Before Buying
1. Battery Health – The Most Critical Factor
A used vape with a bad battery is a fire hazard. Here’s how to check:
-
For built-in batteries: Ask the seller to record a full charge cycle. If the device dies too quickly, the battery is worn out.
-
For removable batteries: Look for swelling, rust, or dents. Use a multimeter to test voltage—anything below 3.2V under load is unsafe.
🔹 Pro Tip: Search for “used vape battery replacement” guides if the device has weak power.
2. E-Liquid Leaks – Hidden Damage
Many used vape devices have internal leaks that cause long-term damage. Check:
-
510 connector threads (for mods)
-
Pod insertion points (for pod systems)
-
Airflow vents (sticky residue means leaks)
🔹 Quick Fix: If you find minor leaks, replace O-rings or seals.
3. Electronics & Buttons – Signs of Wear
-
Fire button test: Rapidly press 10 times—if it lags, the circuit board may be failing.
-
Screen issues: Fading or dead pixels mean water damage or aging.
🔹 Warning: Avoid vape devices with erratic behavior—they may be unfixable.
