It has been designed and developed the portable PKL (Pathor Kuchi Leaf) lantern for practical utilization for smart grid where grid electricity is absent. The PKL converter has been made with an insulated box and electrodes. The electrolytes were prepared by PKL extract. It was found that the portable lanterns were appropriate for PKL electric system. It is found that PKL Powered Lantern has been working well. The novelty of this research work shows that this type of work is very new one in the world. It can be used instead of solar PV sometimes. There are some advantages of this PKL systems compare to SPV (Solar Photo Voltaic) System. This PKL system can be used equally both for the rainy and night time. Whereas SPV system is not possible to use at the rainy and night time.
