This Multi-LED Joule Thief is designed to drain that little extra bit of power from your used batteries while providing usable light. It can also be used with fresh batteries for up to 100 hours of continuous light. This circuit is an upgrade of the popular Multi-LED Joule Thief. The hand wound transformer has been replaced with an SMD common mode choke that is also used on the Joule Thief Candle. The 17 bright LEDs have been replaced with 6 super bright SMD LEDs, there may be less of them but they are brighter. A micro SMD slide power switch replaces the 3D printed switch from V1 and is more conveniently located.
AA battery not included

For international orders, if a shipping rate is not available please contact me and I will add one if it is possible. Unfortunately, international shipping is expensive even for such a small item. Expect it to cost 14.18USD or more for one item. I haven't had much luck finding a lower rate.
