Universal screw-on charger that should work with most vape pen batteries for charging. !!The Correct Way to Charge a 510 Thread Battery!! To extend your battery’s life, follow this simple process: 1. Plug the USB charge into a computer or a laptop USB port (A common block charger in a wall outlet is also okay, provided they are five volts and don’t have rapid charge capabilities). 2. Check the light on the charge — usually, you’ll get a green light on the AC adapter that doesn’t have a battery plugged in, but this will depend on the type of your battery and the brand. 3.Gently screw on the battery now that the battery USB charger is plugged in. Don’t overtighten it because it’ll press on the connection plate too hard and damage it. Screw until you see the light on the AC adapter change colors. 4. Check the light on the adapter — it should change color now that it has a pen connected to it (usually, that will be a red light, but again this depends on the brand and the type). 5. Keep an eye on the device. If you’re charging via laptop or a computer, put something under the battery so it can rest without dangling in the air. It’s done charging usually in under an hour (or when the battery LED light indicates it).
