This simple circuit is presented and assembled well. The attention to detail is top notch. battery clip and pcb quality are outstanding. Amazing writeup at https://samueldperry.com/2017/12/25/multi-led-joule-thief-v2/.

I can't stress enough how awesome this is!

For Multi-LED Joule Thief V2

I have five difference joule thieves and this is by far the best. Very well made. A bargain for the price. So glad I got two!

Simple and beautiful

For Multi-LED Joule Thief V2

I love the clean look. It looks simple. I havent tested electrical but it worked many days on batteries that were too low for the smoke alarm. I recommend this thing.

Love the product

For Single LED Joule Thief Candle

Goes through new batteries pretty quickly, maybe a week when left on all the time.
Uses: reading the Book of Mormon, lighting rock collection.

Great little device

For Multi-LED Joule Thief.

This is an excellent joule thief device at an unbeatable price. Assembled professionally with a neato 3D printed power switch tab. VERY bright! With a little fiddling, it also works with AAA batteries. Seller was frendly and informative. Highly recommended.
