So, can you vape while charging your RELX?

As mentioned, the short answer to this question would be yes. However, doing so is not recommended. To find out why, read below.

Pass-through charging

To understand whether or not can you vape while charging, it is important to understand the concept of pass-through charging. Pass-through charging simply means that the power that your device receives during charging can go directly into powering your usage, meaning you can technically use your e cigarette while it is charging.

Here’s why you may not want to vape while charging

Even though pass-through charging is available on most modern vapes, there are a few reasons why it is not a good idea to use your RELX e cig while charging:

  • Potential overheating: while pass-through charging allows for usage during charging, users who do so frequently are running the risk of overheating their devices and batteries. Contrary to popular myths, this would not directly lead to explosions, but it can cause some degradation to your battery over time
  • Let’s get real, RELX charging is fast enough: as we have said above, a RELX e cig can complete a full charge cycle in under an hour most of the time. Using the device during charging will slow down that charge time, making it take longer for you to get the full RELX experience. Thus, just practice some patience, and we promise you will have a much better experience!


So that’s your answer to the question of ‘Can you vape while charging a RELX?’. Yes, it can be done, but no, it’s not recommended. You are much better off waiting a full charge cycle to get the most out of your RELX e cig. And to save on your next RELX buys, simply input this RELXNOW discount code!
