FAQ

What's the resistance on the LED flashlight?

If 3 heads (3 LEDs), the operating current is 3*20mA=60mA=0.06A, the voltage at both ends of the resistor is 3-0.7=2.1V, so the resistance power is 2.1V*0.06A=0.136W., so the power of the resistor is 1/4W.

Flashlight with 9 LED bulbs, you need a few batteries, a few sections, volts, how much time can take?

A LED bulb is about 10-20ma, and the voltage is about 5V. When a battery is working, the current is about 0.5A

LED what's a good flashlight for?

Said the most simple reliable. Fenix TK35 olight SR51, the two types of personal feeling can meet your needs but the price exceeded 150, indeed, really can not buy a reliable quality of the flashlight, unless it is a AA AAA small flashlight

Just bought Led flashlight flashlight, 5 hours charging 9 hours of electricity, and now there is no electricity, but the charger shows full power, but it is not bright, what is the matter?

The lithium ion battery has a spiral structure inside, and the anode and cathode are separated by a thin film of paper with many tiny holes. Lithium ion battery core is a new type of battery energy. It contains no metal lithium. In the process of charging and discharging, only lithium ion moves between positive and negative poles. Electrode and electrolyte do not participate in the reaction. The energy density of lithium ion core can reach 300Wh/L, and the weight, capacity and density can reach 125Wh/L. The reaction mechanism of lithium ion electric core is that with the charge and discharge, the lithium ion is inserted between the positive and negative poles, and it goes back and forth inside the electric core without the existence of metal lithium. Therefore, the lithium ion electric core is safer and more stable. The cathode of lithium ion battery is lithium cobalt, the positive collector is aluminium foil, the negative electrode is carbon, and the negative negative collector is copper foil. The electrolyte of lithium ion battery is an organism that dissolves LiPF6.

LED flashlight off the ground, it is not enough electricity, what happened?

Many users buy tank007 bright flashlight after the use of the process is not much attention, so that after the use of a period of time, there will always be a variety of problems, resulting in the use of experience reduced.
