You just unboxed your new pen, charged it up, and took a few puffs. All good. But over the next few days, you might notice a few quirks that feel like problems but aren't. For instance, the first charge might not last as long as you expected. That's because lithium batteries often ship with a partial charge, and it takes a few full cycles to reach peak performance. Also, the first few hits might taste a bit 'new'—that's just the coil breaking in. Give it a few sessions.

If you're new to vaping, you might also wonder why the vapor feels thin or the draw is tight. That's often just your technique. Take slow, steady puffs, and make sure the airflow isn't blocked. Most pens have a small hole on the side or bottom—keep it clear.
