Mini thermos or thermo mug DY-PC004 430ml with temperature sensor.

But in order for the readings to be closer to reality, it is necessary to turn the thermos over for a few seconds so that the sensor probe touches this very liquid. Each has one o-ring. Through the essence, the liquid inside has practically cooled down to the ambient temperature. Now to the tests. But let’s not forget that we still have a thermal mug. Nothing stinks, no extraneous chemical smell of plastic. Capacity: 430ml For the initial
temperature is taken as 100 degrees. After another 4 hours (that is, 6 hours have passed since the beginning of the test), the next temperature measurement is 61.8 gr. But in reality, in order not to get burned, you still need to wait a couple of seconds after opening the lid. The results are typical for a thermal mug. Thanks to this, the thermos stands steadily on a horizontal surface.

Mini thermos or thermo mug DY-PC004 430ml with temperature sensor.

In the instructions, the model is called a personal thermal mug. At the seller on the page with the product, this is clearly presented. From the table we see that after 2 hours, the temperature goes from 100 degrees to 85, after 6 hours to 75, etc.
Not immediately, but still noticed that the plastic inserts can be unscrewed, and both separately. Outwardly, it looks like a cheap copy of those that come with Samsung phones. With the advent of winter and, accordingly, cold weather, working in an unheated garage has become not entirely comfortable.
Specification: So, in those that are 500 ml, with a wide neck, not a battery is installed inside, but an ordinary CR2032 battery. After standing for this time, he measured again – 79.8 degrees.
Now about what is hidden under the cover.
It took two weeks from the date of dispatch to receipt. She incidentally was in district 23-24 gr. When fully discharged, Lo is displayed (from the English Low – low). Pack weight: 300g Sometimes it starts to glow on its own, just being at rest. And in this form, as it is now, the readings can be easily seen even in bright daylight. There is no additional cork inside. Graphically, an exemplary structure looks like this: Size: 230 x 65 x 65mm This time the delivery was indicated by the CSE courier service, but due to the lack of people, I had to go to the pick-up point and pick it up myself. Thanks to the manufacturer for not putting red, otherwise the readability would have dropped dramatically during the day. Just above the indicator, we see, covered with a rubber plug, an input for recharging the battery. In the kit, by the way, there is also a simple and cheap microUSB cable and instructions in Chinese and English. The dimensions are as follows: in length – 23.5 cm, in diameter – 6.5 cm. The LED indicator is very bright, as is the LED next to it, and when driving in transport, they themselves can be activated, attracting the attention of strangers)). On the lid it has a sensor that displays the current temperature inside the vessel. I noticed this when pouring hot water inside. In theory, this design should prevent contact with the hot walls of the metal bulb. -Despite something inside there is a plastic insert for drinking directly from a thermos, contact with hot metal is inevitable. To activate the indication, it is enough to grab the metal part of the lid or shake the thermos itself. For example, at a temperature of 75 to 100 degrees, the diode lights up red, at 50-70 degrees – yellow, and from 25 to 50 degrees – green. By the way, you can see that the digital indicator is red there, and there is no port for charging the battery at all. The temperature for thermocup keeps normally. After looking at a little more information about this thermal mug, I learned that there are several different colors and combinations.
In addition to the digital indicator, the temperature level is also indicated by a separate LED, also located on the top of the flask.
Well made, the case is durable, withstood several drops on the wooden floor in the garage. First poured some hot water to warm the vessel inside. Well, in conclusion, let me summarize. It is placed half a centimeter from the body in the form of a metal probe. Close the lid tightly and leave for 2 hours. The neck is narrow, about 4.5 cm in diameter. There is a slight inconvenience, but do not fill the same water to the brim. The packaging is an ordinary white box, without any inscriptions talking about the internal contents. It is necessary if tea or other herbal tincture will be brewed in our thermocup. It is clear that in real conditions no one will pour boiling water into a thermos. The green indicator is better readable (it costs more), inside the battery instead of a battery. Material: 304 stainless steel Review published in accordance with clause 18 of the Rules Not in the best condition, I was afraid that the thermos itself would be damaged. Enough charge, I’ll tell you for a long time, almost a month. It is not removable and does not have a cavity for storing tea bags, coffee bags, etc. It cannot be said that they are bad or that, on the contrary, they are outstanding. Small, with a silicone carrying handle. You can’t force it to turn off. The internal battery is charged in almost 3 hours, it includes about 300mAh. /> It turns out that this manufacturer has a whole line of models with different capacities. On the product page, you can find a table with heat / cold retention graphs for the liquid poured inside. I honestly do not know what kind of principle of work is implemented here. I chose not overall, with a small capacity. From the preview, I think everyone has already noticed how it differs from the rest.
The silicone handle is attached to the plastic ring, closer to the neck of the thermos. her in
You can easily remove it if you don’t need it. The advantage is that you can always find out the temperature of the liquid without opening the lid. I’ll note what I liked and what I didn’t: It has three colors and depending on the current temperature range it can flash green, yellow or red.
But the main feature of the thermos is a digital screen showing the internal temperature of the vessel. He stopped, as it seemed, on the prettiest, black with blue accents. For a month of using this product, I found for myself a minus in the implementation of this chip with the temperature output. -I didn’t like that you can’t forcibly turn off the temperature sensor.
If you unfold the cover, then we have a view of how the temperature sensor itself works. Contact of the lower lip with the metal walls of the vessel is inevitable. While charging, the message is displayed
Ch (from eng. The temperature sensor will show the temperature of the liquid, without unscrewing the cap. The results are the most common. In this case, I decided to get a small thermos. It can be activated with any shake. My version, despite the smaller volume, looks more interesting. The model is designed as a cross between an ordinary mini-thermos and a thermal mug, there are signs of both.
The outer casing is made of painted metal with small plastic inserts. The product was provided for writing a review by the store. Weight: 270g There is still no electricity, so I can’t use the kettle either. Name: Vacuum Thermos Cup
There is also a metal strainer hidden inside the neck. Minus 33.7 gr since the start. Full – full). Minus 15.7 degrees. Well, it became interesting how it would work in reality, and besides, the capacity turned out to be just what I needed, i.e. small – 430ml. Color: white, black, pink
White cable, 1 meter long.
Rubbed midsole.
But taking it out, I saw that everything was intact, without visible dents.
Live hero of the review looks much better than in the photographs. It is also written about it in the instructions, which, apparently, are universal. I was not able to disassemble the lid, perhaps this is not possible at all. I drained it and poured the already newly boiled water again, measured its temperature – it gave out 95.5 degrees. Empty weight – 330.3g. This is a separate plus. Inside there is a plastic lining with rounded edges. It is placed inside the cover and is presented in the form of a two-digit, seven-segment indicator with a green backlight. There is a comfortable silicone carrying handle. And this beautiful specimen with an unusual feature caught my eye.
To measure the temperature, I used a folk thermometer TP101 with a probe (for meat). You can see the weld: Charge – charging), after the end of the process it changes to Fu (from eng.
The vessel inside is 430 ml and, according to the manufacturer, is made of stainless steel grade 304 (food grade steel). The design is cute, the color is not just black, but with iridescent sparkles. Colors are as chosen — black with blue accents. Actually for this reason, the lid cannot be used as a travel mug where our drink could be poured. Price with coupon BWBCP is $16.52.
The lower part of the case is covered with a plastic rim.
The thread on the outside: Pack size: 250 x 80 x 80mm In it, you can also see the diagram of the device in the context and everything else.
Well, since we touched on the topic of the sensor, I’ll tell you about how it works.

Review of Fineblue FD600 – bluetooth headset for music and calls

For details, please under the cat The Fineblue FD600 wireless headset is interesting primarily for its ergonomics and convenience. In this case, the smartphone itself can be put on silent mode. For a couple of weeks of use, I completely changed my opinion about her, frankly, some moments upset me, but at the same time, she was able to surprise with unexpected possibilities. You will definitely not miss a call, because the vibration is felt very well by the neck. At the same time, the use of only one earphone makes it possible to freely hear the environment with the second ear. Actually, I consider the appearance, or rather the way of wearing, to be very successful. But we immediately see an obvious drawback – the wires leading from the headboard to the headphones are somehow flimsy. Specifications are on the reverse side. The buttons are large enough and conveniently located. And as practice has shown, at a low volume it is quite real. The declared capacity of the built-in battery is 170 mAh. A separate button for accepting / rejecting calls and a little further, buttons for controlling the volume / switching tracks. You can not speak loudly, the sensitivity is high. The magnets are weak, but sufficient to hold the headphones. From a full charge, we are promised up to 16 hours of music playback. If the headphones are not currently in use, they can be magnetized to the headband so that they do not dangle when walking and moving. The equipment is minimal – a headset, a small micro usb cable for recharging and instructions in Chinese and English. Initially, I considered it as a headset for everyday use and sports, but it showed itself in a different way. Of course, you can use both, but for conversations it is more convenient for me with one. There is an LED showing the operation of the device – everything is standard: blue flashing indicates operation, red indicates a low battery charge. When walking, running – any activity, the headset does not restrict movement in any way. Another plus in the direction of the headset for conversations is the vibration motor.

Review of Fineblue FD600 – bluetooth headset for music and calls

The microphone is built into the base and perfectly transmits the voice. The main part, where the buttons, the battery, the microphone and the control board are located, is worn around the neck. And the headphones themselves are already inserted into the ears in a standard way. The soft headband is almost not felt. The interlocutor hears you very well, no extraneous noise. In addition, it is convenient that you can use only one earphone, for example, for a conversation, while the second one will not interfere. Most likely they will die precisely because of wear and tear, but time will tell how long they will last. There is a note about built-in magnets. The headset is delivered in a blister pack, the main features are shown in the form of pictograms on the front. You can also control the charging process by the LED. It works with devices that support the Bluetooth 4.0\4.1 protocol. As time has shown, these headphones are ideal for communication. The instructions have some useful information, such as how to connect the headset to two devices at the same time.

USB tester Fnirsi FNB38 – Top…

The first of them is PD Listener, judging by the same thing as PD Trigger – it shows a list of profiles, but without the ability to switch to the selected one. We take the tester, holding down the "OK" button, connect it to our computer via the HID USB (microUSB) port.
The fourth worker became a kind of mini-oscilloscope.
The control is implemented through three buttons located on the upper end of the case (“OK”, “Back”, “Forward”) By the way, it is quite convenient to use, especially against the background of one-button options from YZX Studio. Not all mobile devices can be charged with QC3.0 / 2.0 chargers in fast mode, as they only support PD.
The format is already classic – in the form of a small flash drive. Recording in memory.
All of the above suggests that the evolution of the development of usb-doctors from the Chinese has taken a long step forward in recent times. In the new software, the font of the text was slightly increased, otherwise everything remained the same. And if the previous v1.20 could be called a passing one, then the last one already has an impressive list. It usually contains all information about the product and is needed for currents above 3A and
high data transfer rates (from 480Mb/s and more). What most of the closest competitors do not have is a full-fledged charging protocol trigger. Trigger: Yes, Manual/Auto < br />Measured voltage: 4 – 24V Brand: FNIRSI The FNB38 model has already been reviewed on the site more than once, so I will not repeat it.
The tester arrived with version V1.10. Most of the changes and additions were carried out with this item. An excellent advanced USB tester that provides all the same functions as more expensive competitors for little money. It scratches very quickly, just wipe the surface with a regular cloth. With each version of the software, many useful changes are added, fixes for past errors. The FNB38 model also has such functionality. And now, of course, there is no one like that
you won’t be surprised.
Next, we will analyze in more detail the functionality, as well as all the new features.
PD Convert (or QC2.0->PD protocol convert) – can turn any ordinary charger with QC3.0 / 2.0 and a regular USB-A port into a modern one with Power Delivery support. Capacity: up to 99999, 9 mAh or 9999.99 Wh, memory 5 cells We update the firmware to version 1.30.

The product was provided for writing a review by the store. The first of them is the most primitive, remained without any changes. Complete set without surprises: device and one-sided color booklet. And this is done so that the tester can withstand currents up to 5A (spec limit). We reworked the algorithms for testing fast charging protocols, expanded it, and also added something that was previously missing. Download and unpack two archives with files: FNB38_TOOL.rar and Fnb38_Frimware.rar. Firmware number 1.30 brought a number of new features, with which the FNB38 can now be put on a par with such expensive models as WEB-U and ZY1280 (which cost twice as much). Here displays the serial number of the product, the number of inclusions. 13 items for fine tuning are also available. The first one is the software update software via PC itself, and the second one is a folder with firmware and a list of changes for each version. The quality of charging cables can be easily tested (but an electronic or resistive load is required).
During the manual test, the maximum power display also appeared in the PD Trigger section.
USB-A version 2.0 interfaces, with reinforced power contacts. A prompt will appear on the screen in the form of the inscription DFU 1.10.
The sixth screen is perhaps the most interesting item. We’ve entered bootloader mode.
For example, the photo below shows the results of fully charging a Redmi Note 8T smartphone. The main focus will be on the study and detailed analysis of new software, which has brought quite a few fixes and additions. The information of the minimum and maximum values ​​of current and voltage is displayed in the form of graphs.
Now consider the new items in order. With its help, you can, for example, find out the charging time of a particular device, determine the filled capacity, etc. When the tester is connected to a power source, the first two seconds are spent on displaying "Advertising". A couple of years ago, simple testers with primitive indicators, displaying only current and voltage, were from the category of super technologies. Review published in accordance with clause 18 of the Rules
I won’t talk about each in detail, I’ll highlight only those that appeared in firmware V1.30.
PD E-Marker is a special section that allows you to scan USB-C cables for the presence of a specially integrated E-Marker chip. The wire from Choetech tested in the photo below does not have such a microcircuit. Measured power: from 0 to 120W Earlier there were only 7 lines here, now there are 10 of them (there are PD Listener, PD E-Marker, PD Convert). Measured current: up to 5A
Everything is ready to continue the flashing procedure. As already mentioned above, you can enter this menu by holding the "Back" button before turning on the power. Below is a detailed list of changes in software V1.20 and V1.30: CC Pull Down and Start Page. The first is responsible for turning on or off the power on the CC data lines using the Power Delivery protocol, the second allows you to deactivate the display of the start page. The tester arrived just like everyone else – in a metal box with a transparent window on the front side. A good example is the latest iPhone models. I am glad that the developers have not abandoned support for this model and continue to update it. Added display of the maximum power of the device under test, according to the PD protocol, as well as the number of profiles.
Parameters: After 63 seconds, the process will end and the tester will automatically switch to the hidden settings mode already with the new software.
Conclusion The case is an assembly of several plates and the main board on metal racks.
Let’s move on to desktops. A kind of scanner that can determine which types of charges are supported by a particular device (memory, power bank). She can now
The fifth screen is used to determine the resistance. I hope that in the end the device will be brought to the ideal (or at least squeeze out everything that is possible). And since the device is already in the settings menu, let’s start with it. Many doubted that the manufacturer at such a low price would somehow support the product by releasing fixes and additions. Now there is a check for support for such types of charging as Apple and Android DCP. The front part is occupied by a 1.44-inch color screen, covered, as I said above, with ordinary acrylic glass. Built-in thermal sensor. But I use the FNB38 tester and this function can simulate the desired configuration. If you believe the numbers, the resistance is only 0.12 Ohm, which indicates
low voltage drop under load. In the photo below, I checked the meter-long microUSB cable from Voxlink. But for some reason, at the time of preparing and writing this review, the manufacturer’s link was inactive. Today I would like to talk about such a useful device as a USB tester. Resolution: 0.0001 V / A
The third screen is similar to the previous one, but it also indicates the current charging protocol and voltage along the data lines (D , D-).
The next screen, on the contrary, is the most functional, but also without additions.

USB tester Fnirsi FNB38 – Top for your money. After that, the system may issue an error alert, ignore it and just press START. The functionality of this menu remains the same.
One of the distinguishing and key features of Fnirsi USB testers is the ability to update the firmware.
I had to contact the seller and ask to send the files individually. Software update
Without exiting this screen, by holding down the “Back” button, you can open a table with the output of capacity results for all five memory groups. Model: FNB38 As a result, I received a direct link to a folder with software for FNB38. The QR code on the booklet is not accidental.
But before moving on to the study of new ones, let’s look at the old section of the autoscanner (01 Protocol detection).
If suddenly someone did not understand what kind of start page we are talking about, then I will clearly demonstrate it below. Here is her address below: In the photo below: the subject of the Fnirsi FNB38 review, a competitor from RD UM 24C, the old white “doctor” KCX-017. At the same time, be sure to remember to set the lower current limit through the settings menu (cut-off, according to which the tester will stop counting). When scanning it, we should be directed to the official website of the company, to the section with everything you need for self-flashing.
Go to the FNIRSI USB Meter program on the computer, select the desired file (software version). But as you can see, today the third software is already available – V1.30. These are lines numbered 12 and 13: According to the changelog of version 1.30, work was done to correct the output of these values ​​(zeros were sometimes displayed). Promo code FNIRSI1 is currently valid for the product, which gives a $3 discount. It is very easy to see what firmware is already installed on your device, press the "Back" button and apply power in any way.
A large number of various ports are provided for connecting and communicating with external devices: including two MicroUSB inputs, one of which is used for independent power supply, two Type-C ports (for input and output), and as well as full-sized USB-A (father and mother).
