LED Petromax
One day, the residence around Jono’s house had an accidental event. This made Jono and the surrounding residents restless. So Jono and the local residents made an initiative to hold siskamling in turns. On the night when Jono was on guard, Jono used the Petromax LED lights for lighting. But when before nightfall, Jono had to charge his LED Petromax so that it could light up overnight using electricity connected to the USB cable, if not charged, Jono had to buy 3 AAA batteries. Because the Petromax LED lights were only obtained by Jono this morning from the Bulakapal online shopping store, Jono did not yet know how to use them.
The first thing Jono has to do is unboxing the package from the J * E expedition, then the next thing to do is to check the condition of the item. Because Jono bought the Petromax LED lamp for the first time, the next thing to do is read the guidebook in the box. There are explained various kinds of things including: First, the Petromax coated with plastic material is electrically powered which must be charged when the battery will run out or can use battery power. When charged, the Petromax LED responds / gives feedback in the presence of a red indicator light, on the contrary, when the power is disconnected or is not being charged, the indicator light does not turn on. Then when the Petromax lamp is fully charged, the indicator light will turn off or not turn red again. When Jono turned on the Petromax LED lights, there was only one button on the side of the lamp in the form of power on / off and the light level regulator to 10 levels in the form of a lever that can be adjusted according to conditions, the lever turned to the right, it will get brighter. For how to carry it is quite easy, the lights can be carried in one hand.
So, this Petromax LED lamp is very helpful for Jono’s activities when siskamling. Because this lamp only lasts 4–6 hours, Jono must be prepared to bring Power Bank to charge backup and prevent the lights from suddenly dying.
Opss, it was already 10:30 p.m, so it’s time for Jono to go around the village to be helped by using Petromax LED to illuminate the road and maintain the security of the residents.

After turning on the lid or pointing the lever to light the fire up. And after turning on, then pull and press the pump again to keep the flame burning for longer, because in general if the container is fully filled with kerosene and the bar on the lid reaches the maximum limit, petromax will light 8–10 hours.
After Dolah’s Granpa lit a petromax, Dolah brought petromax to the living room. In the living room, all gather while waiting for electricity not to go out while telling stories and enjoying the warmth of togetherness together with family.
