… I’ll add that the turbo mode of the flashlight, with the protected 26650 5500 mAh - does not work. Why is the manufacturer silent about this, and did not immediately write down which batteries to use with a flashlight, protected or not? And he does not want to solve the problem and he does not give advice, he does not answer questions,. The driver of the flashlight is not completely thought out. The rubber cover for the USB cover is also not thought out, it clings to your finger and opens constantly when using a flashlight.
