### ⭐⭐⭐⭐⭐ Great product
*by W***K on January 11, 2026*

Okay I was a little worried first time trying this product, but let me tell you! Get it I am so happy with this product. I have a 18650 batteries and my device has a charger built inside but it can only charge it 25%. My batteries were only lasting half a day. I did one full charge with this imren charger. And my I used my vape all day and it never left a full charge all day. Very good product. If your on the fence on which one to get, then get this one! I highly recommend it!!!!
