Does the title of this review seem risky to you? Yes, it can be .. but I assure you that after trying it the doubts about it have been completely wiped out! The NexTool Thunder 12 in 1 flashlight (Xiaomi ecosystem) is an absurd device, which I never even thought could exist! But let's see why: PACKAGING In the package, well made, we find: The flashlight A USB-Type charging cable CL English-Chinese instruction booklet FUNCTIONS AND DIMENSIONS The functions of this wonderful flashlight are truly multiple, let's see them all then we will go into detail: 4-color LED torch: white, red, green and blue Power Bank (1400mAh at 5V 1A) BlueTooth speaker with controls included RGB side light with preset programs (including emergency signaling) Light + emergency buzzer Magnetic and screw attachment (for tripod supports) Battery 2600mAa (3.6V, 9.36Kwh) The weight is about 245Gr, the dimensions 173x36x43mm, made of aluminum alloy and polycarbonate, it has an IPX4 waterproof rating and a drop resistance up to 1m. Excellent magnetic coupling that will allow you to attach it where it will be most convenient, perhaps while checking for a malfunction of the machine. TORCH USE Let's say the main use! Well, really fantastic. The thing that really struck me, besides the power, is the possibility of using it with 3 different colors in addition to the classic white light. To turn it on, just click for 1.5 seconds the power button (the central one) that you will find at the base, the same to turn it off. In my case, at the first start the RGB side light started, if it were the same for you, you just need to press the same button twice quickly to switch from the side light to the front one. The intensity can be adjusted using the "+ and -" keys that you will always find at the base, where there are all the controls to take advantage of all the functions of our NexTool Outdoor Thunder! At maximum power you can light up to a distance of 250m thanks to its 900lm! To adjust the size of the light beam you will have to pull in and out the ring that contains the LED. Below I summarize all the powers that can be supplied according to the various colors and relative autonomy: White: 35lm-900lm, maximum autonomy 2.4h-40h Red: 3lm-95lm, maximum autonomy 3h-32h Green: 6lm-160lm, maximum autonomy 4h-48h Blue: 0.5lm-20lm, maximum autonomy 4h-45h To switch from one color to another, simply press the power button quickly. USE OF AMBIENT LIGHT Surely the function that struck me most! In fact, we find on the side a surface of about 8x4cm used for ambient RGB light and signaling. Really useful if you find yourself in a breakdown with the car or for your evening \/ night walks. There are a series of preset programs that you can activate by pressing the power button for 1.5 seconds from off and twice quickly from the classic light mode. Once this mode is enabled, you can switch from one program to another simply by pressing the usual power button (quickly). The preset programs are as follows: automatic color change color change with background music (mood music) red red flashing white To increase and decrease the intensity of the light you can click on the "+ and -" buttons. MUSICAL MODE Well yes .. this flashlight will also act as a BT speaker. Of course the power is what it is, don't think about replacing a real BlueTooth speaker with this one. but it can always be useful in case you are in company and nobody wants to drain the battery of their smartphone. To connect it to a device, just press the button with the musical note \/ play-pause logo for 1.5 seconds (same procedure to turn off the BT). At this point the green side light will turn on indicating "BT active but disconnected", then look for a new BT device from your phone (it will find Nextool Thunder) connect it and you will see that the light will change from green to blue. Now you can start your favorite song and listen to it through the speaker of the flashlight, at this moment the side blue light will turn off. When the BT is turned on and off there will also be a guide voice that will tell you what happened, but in Chinese, therefore, a bit difficult to understand. If you also want to have the side light on during music playback, just click twice on the music note button or for 2 seconds on the power button. ADDITIONAL FUNCTIONS But our nextool outdoor thunder flashlight never ceases to amaze us and gives us 2 other interesting features: ALARM: by pressing the power button for 3.5 sec we will enter the alarm mode so all the lights, side and main will flash cyclically and emit a sound note of alarm. In this mode the autonomy will be about 3 hours. https:\/\/youtu.be\/R9Jg--Zk32c POWER BANK: nel caso siate a corto di batteria potrete dare una piccola carica al vostro smartphone, potrete infatti sfruttare 1400mAh a una potenza d'uscita di 5W. FINAL Considerations As you have seen the possibilities of use of this beautiful NexTool flashlight, I remind you that it is part of the XIAOMI ecosystem, they are really many. It is really a tool that can prove to be very useful in many circumstances, so my opinion is absolutely positive! The list price is around € 75 but thanks to a fantastic offer from BANGGOOD (which we thank for sending the sample) combined with our coupon you can take it home for only 42 !!
