The Ugreen HDMI to VGA adapter cable comes in excellent sealed packaging with a micro USB power cable that I did not use. It is suitable for computer monitors, televisions, projectors, and generally any device with a VGA input port. The adapter casing is made of glossy plastic. The 16 cm cable that connects the two plugs is flat and quite durable.
I have been using the Ugreen adapter for 11 months on a computer that does not have a VGA output to connect to an old monitor with a resolution of 1920 x 1080, and it does a very good job. It also has a 3.5mm jack output for connecting the HDMI to speakers, which means it can also serve as an HDMI to Audio output adapter.
It is powered by a micro USB port, but in my case, it works without any additional power source. The only downside is that the connection is only one way, from HDMI out to VGA in (the opposite is not supported). This video includes unboxing, measurements of dimensions, as well as testing the HDMI-VGA adapter on a wired connection from a Dell Inspiron 15 laptop to a Panasonic TV: https://www.youtube.com/watch?v=KcgdSGVvmsQ
In addition to the charger, the package includes detailed instructions in English and a useful 50cm USB-A to micro USB cable. It has a micro USB input, USB Type-A output (for using the charger as a power bank), 5 protections for the batteries, and 3 special functions. It has a sturdy construction with a fairly good charging slot spring. It is a compatible charger with almost all types and sizes of batteries, even with special batteries like LiFePO4. It has two charging current options of 0.5 and 1A. For NiMH or NiCd charging, the options are 0.1 and 0.5A. The supported charging protocols of the Type-A output are: Apple 5V/0.5A and BC1.2 DCP 5V/1.5A. At this low price, the absence of fast charging QC, PD is justified, as the function of this particular integrated power bank is more for emergency charging needs. Simple and practical LED charging indicators, current selection, etc. The Liitokala Lii-100 charger does not overheat at all, even in the summer. It also automatically stops charging when it is completed. I measured a maximum charging current of 0.98A 5V, which is equivalent to almost 5W. All the batteries I tested on the Lii-100 charged without any problems. Its weight and dimensions are 44g and 113 x 38 x 30 mm respectively. If it were a few millimeters longer, it could easily charge 20700, 21700 batteries. The following video contains many compatibility tests with various batteries (type and size) as well as measurements of the charger's input and output maximum values: https://youtu.be/6hxXndIJSWg
Not satisfied at all with the overall performance of this specific Esperanza spray. The reasons are the following three:
- The tube adjusts with some difficulty and only from one side.
- The air pressure is from moderate to low.
- Also, the air pressure drops quickly (I didn't manage to clean 3 120mm fans and its power almost reached the bottom).
The corresponding Lanberg air spray of 600ml has much longer duration and pressure, which is evident in the video I made with a test on a PC.
This is my first be quiet! power supply (700W version). I have installed it in my mid-range PC (MSI MAG B560 Tomahawk, Intel Core i5-11400, Corsair Vengeance RGB Pro 2x8GB, WD HDD 3.5", Crucial SDD 2.5", Asus BluRay Drive 5.25").
The power supply comes in a simple box, wrapped in bubble wrap bag without unfortunately any pouch even though it is a B-tier category intended for mid-range and high-end builds. It comes with 7 internal cables (5 of which are detachable) and a classic AC power cable 1.4m long. The internal cables are all short, which means they are not suitable for most full towers.
The overall construction of the PSU unit is of high quality, heavy (1729g), flawless and has 2 non-detachable sleeved cables: 1 for motherboard (20+4pin) 550mm and 1 for CPU (4+4pin) 600mm. The power supply operates flawlessly, I did not notice any restarts or overheating.
The noise of the very good fan is minimal at low and medium loads (up to 560W) at higher loads above 665W, which is prohibited for use, the intensity exceeds 30db. Even when I tested it in demanding rendering, the sound was low and I had to bring my ear close to the back of the case to hear it.
It was tested and passed the compatibility test with APC line-interactive UPS. I will come back with an update on its performance at high loads as soon as I add a graphics card to my system. In this video, I have included measurements of cable/PSU dimensions, fan noise samples, output voltages, and many other tests of the be quiet! 700W power supply: https://www.youtube.com/watch?v=dH5lX180K14
I tried the Meliconi AMP200 amplifier on a television with weak signal (about 40% quality and 85% intensity) by connecting two relatively good quality 1.5-meter IEC antenna cables. While the amplifier initially worked extremely well, providing 100% signal on all channels, after 1 day the problems reappeared and the signal dropped below 20% on all nationwide channels. The signal quality was even worse on HD channels. After changing the cables, restarting the amplifier, and retuning the channels, I did not see any improvement in the significant pixelation issue. In reality, this amplifier creates more interference in the image than signal enhancement. I should note that I connected only one television. To make sure before writing this negative review, I bought an amplifier from a major satellite company (it cost me 6 euros more than the Meliconi) and the problem was immediately solved. For those curious to see a detailed demonstration of how poor the performance of the Meliconi AMP200 amplifier is, I have made a video with tests in front of the camera, check it out here: https://www.youtube.com/watch?v=AcH8wTum07A
The Thermaltake Riing 12 Series is available in six fixed colors. I acquired the blue LED version. I put it to my new midrange gaming PC as exhaust rear case fan. It can be used as radiator fan as well. Inside the box we find the Thermaltake Riing 12 Fan, an LNC (Low-Noise Cable 130mm), a Molex to 2-pin power cable 320mm, four M3 thread screws and four coarse thread screws. The fan's PWM cable is long enough (450mm) and is routed on the right side. Only downside is its 3-pin connector. All included cables feature well-made connectors and braided sleeving with insulation. Thermaltake offers a 3-year warranty for this product. The aesthetically pleasing fan has great quality and features a matte black color housing. Its deep blue LED ring is not bright and you cannot turn-off or change the color. Ring lighting effect is visible from all sides and angles.
I've got to say that both rear and front sides have rubber anti-vibration pads. Thermaltake fan is very quiet and I can only hear it when I put my ear close to the case. I plugged the fan's 3-pin PWM cable (without LNC) into the SYS_FAN1 header (4-pin) of my MSI motherboard (MAG B560 Tomahawk WIFI). You can control the fan speed via MSI BIOS by adjusting its voltage (6.24 - 12V). I measured a max speed of 1655 RPM which is 155 RPM higher than the manufacturer's claimed speed. The fan does not get loud even under its max input power and delivers efficient airflow. I didn't notice improperly functioning.
Check out also my deep review video in which I unbox, test (on camera) and demonstrate how silent the Thermaltake Riing 12 fan is: https://www.youtube.com/watch?v=6eLe777bzXQ
This Soocas oral hygiene product is FDA approved. Product arrived sealed in 6 boxes. There are 50 per box dental floss picks which are disposable. The built materials are food grade PP (body) and high molecular weight polyethylene fiber (floss). Toothpic (tail part) is rounded and elastic. The soft, thin (1mm) fiber is extremely durable and break-resistant. Both floss and pick are tasteless and odorless. In my testing, the handle broke after I pushed it 7 times to high stress levels (its maximum load-bearing is 3.15kg). The firmly fixed fiber didn't break or crack although I tried hard to damage it. It does not absorb water, neither exfoliates. Another plus is that it easily glide through tight spaces between crooked teeth. Check also my review-testing video of the product here: https://www.youtube.com/watch?v=omA_43B-5yU
The Vention 3.5mm Male to Male Braided Audio Cable is available in six lengths to choose according to your needs. This is the longest version (5m). It came in a sealed plastic bag. The wire feels very durable but lacks a velcro strap. Metal alloy housings are well-built. Their main built material is metal alloy while featuring reinforcement on each housing. The Vention cable adopts two 3.5mm TRS male connectors and doesn't support a microphone. I've got to say that the housings are well designed and so skinny that they fit in limited space ports. I plugged the cable into many devices even Bluetooth ones, to test its outperformance and lag. It worked flawlessly on all my testings and had good balance in mids, highs, low frequency. Check out my testing review video of the Vention 5m cable here: https://www.youtube.com/watch?v=VCofaSKXOvA
I have been using their case for the past 6 months to store two Orico enclosures for 2.5" hard drives. This specific case has an external carbon fiber coating, making it suitable for transportation and travel. It comes in 5 variations of materials and sizes. It securely closes with a durable zipper, and its interior has a velvet lining to prevent scratches. One side of the interior has a strong elastic mesh for storing cables, memory cards, flash drives, earphones, etc. I should note that it comfortably fits a second hard drive enclosure. Its external dimensions are 151 x 107 x 40 mm, measured with precision calipers. It weighs only 72.5 g. It is also water-resistant. It initially has a plastic smell, but fortunately, it disappears after a few days. I highly recommend it without hesitation for storing/transporting sensitive electronic devices.
In this video, the Orico case is presented in detail, along with a compatibility test with two different USB external hard drive enclosures: https://www.youtube.com/watch?v=VRXK49R0gbU
