Recharge this portable light again and again—the non-removable lithium ion battery delivers long-lasting performance.

Trust in Energizer for reliable performance in any situation.

Review: Perfect for automotive - I started school recently in the automotive program, I was looking for a small flashlight to keep in my shirt pocket but also bright enough to see in small dark places. This does everything I need it to do. The light output isn’t a groundbreaking brightness but it makes it plenty light enough to see. It has a small adjustment for a narrow beam or wide, again, just fine for what it needs to do. The battery will not last forever so just make sure to keep it charged beforehand. I’d recommend this to anyone considering the build quality and price. Edit: After about a month of use (at most) the flashlight has died on me. The switch started to stick and would get stuck in the on position. After finally getting the switch to back out for me to turn it off, it will not longer stay on by itself, I have to hold the power button in order for the flashlight to illuminate.
Review: well made with a bright light. - Well made, batteries included. Slim and has wide, bright light.

### ⭐⭐⭐⭐⭐ well made with a bright light.
*by W***I on January 29, 2026*

Well made, batteries included. Slim and has wide, bright light.

### ⭐⭐⭐⭐ Still no USB-C??
*by M***G on January 4, 2026*

Best pen type flashlight on the market. Only 2 problems that I had, 1 I dropped it a few times and it’s claims of durability aren’t as good as they say, they were never more than from a couple of feet. The easiest fix though is the charging port. It’s 2026 people, USB-c is pretty standard even on cheap toys from China. I think energizer can figure it out. Otherwise this is a great buy, super bright and heavy in a way that makes you feel like it’ll last for a long time(although mileage definitely may vary). Would recommend or buy this for friends and family for sure.
