Product review: Solar LED Lights by Linkertech Waterproof



I got a pair of lights. One of them stayed on only for a few minutes after a full day of charging initially and a week later did not turn on at all. The other one stays on for about 3 hours (by 11 pm it is off). Both are very dim, they light only a tiny area right around the light. The stock photo makes them appear much brighter than they are in real life. Are the lights decorative given that they do not produce much light? No. The lights do not look as nice in person as they do in the stock photo. The plastic has a cheap look and they do not look nice when it is light outside.



I took several pictures (setting the camera to manual mode so the camera does not try to compensate for the darkness). I also measured the light it generates with a lux meter (which measures intensity of the light) for an unbiased measurement in addition to my perception of the light level.



This light produces 172 lux when the meter is placed right next to this solar light.

This light produces 10.3 lux when the meter is placed 12" away from this light.

For comparison a 60 watt fluorescent bulb at the same distance of 12" produces a reading of 1110 lux.



The light is 4.5" (tall) and 3.5" (wide), it extends 2" from the wall.



The light is photo sensitive (i.e. it turns on when it is dark). Inside the cap there is an on/off switch to preserve the battery during shipping. There is no label which shows the on/off position. On position is when the switch is pushed towards the narrow side of panel.



These lights were a disappointment.

Product review: DUXTOP UltraThin Full Glass Top Touch Induction Cooktop



The best thing about this cooktop for me is that it keeps a steady temperature, this makes it much easier to cook some thing without worrying about burning. When searing steaks or making fried chicken the results come out better than using a conventional stove.



A ran a couple of experiments to help me see if the cooktop temperature is accurate and if it in fact holds the temperature at the point I set.



The temperature can be set in increments of 10, so to keep it just below boiling I set it to 200. I let it heat water for 12 minutes while measuring the water with a temperature probe (calibrated to be accurate within 2 degrees). The cooktop kept the temperature between 192 degrees and 183 degrees. This result was consistent on several tries. So even though there was a difference between the temperature the cooktop held and the specified goal temperature the there is difference between the two was consistent I can adjust for the difference (I use 10 degrees). I guess it is like learning a new oven they are all slightly different.



The second thing I measured is how it compares to my gas stove. I used the high powered gas burner and cooktop at its maximum setting (level of 10 and goal of 460 degrees). I used 1 cup of cold water and the same cast iron pan. The cooktop took 1 minute 50 seconds to bring it to boil. The gas stove took 2 minute 25 seconds before the water began boiling.



Another interesting difference was the distribution of heat. The cooktop began boiling in the center and then spread outwards (but still showed a hot spot in the center). On the gas stove the boiling began on the edges of the pan and then moved to the center of the pan.



The cooking surface is heated only when the pot is present. The control system shuts down the element if a pot is not present or not large enough. The cooktop itself does not get hot at all, so nothing gets burned and baked on it and it is very easy to clean by just wiping with a wet cloth.



Not every cookware works with the induction tops. This is because induction works by electromagnetic induction. This means to work on the induction top the pots must be made out of magnetic metal such as cast iron, stainless steel, and enamelled iron. In addition the bottom of the pan has to flat and make contact with the surface of the cook top and not too small (larger than 4.75" in diameter).



What cookware does not work? Heat-resistant glass, ceramic, copper, aluminium because none of them are magnetic.



I was able to cook pancakes at a constant and lower temperature and I thought they came out better this way. For steak I set the cooktop to the maximum temperature and the highest wattage. I was able to get the cast iron pan very hot which, of course, is the key to searing meat. For fried chicken, I set the temperature to 370 degrees (which translate to 380 degrees on the cooktop display) and cook it on both sides for 5 minutes, then finish it in the baking oven for 20 minutes at 375 degrees. The chicken comes out very crispy.



The cooktop is not as precise or as accurate as I hoped, but it is consistent so this is not a deal breaker just requires adjustment by the cook to know how their cooktop behaves. Everyone learns what to expect from their oven so this is similar.

Product review: Durapower 500lm Rechargeable LED Work Light Bar Cordless



This work light exceeded my expectations. I did not fully understand how versatile it is until I began using it.



✔ I can hang the light horizontally using magnets on my HiLoft storage system. HiLoft shelves are a metal grid. The magnets are strong enough that they work even with this "sparse" support. The magnets work great on a solid sheet of metal, of course, like a hood of the car.



✔ I can hang the light by one or two hooks, providing me light either horizontally or vertically depending on the space I need to light. I have a long a narrow area behind the furnace where I every few months we need to change the filter, it is always a struggle to see what is happening because the furnace shades the overhead light and it is difficult to hold a flashlight while changing the filter. Now the problem is solved.



✔ The light can be rotated so the light provides the light to an area but not beam into my eyes.



✔ The light runs on a rechargeable battery, so when I use it I don't need to have it plugged in. (In fact the manufacture warns not to use the light while it is being charged).



✔ It has two modes low and high, both of modes are quite bright.



When I first opened it I wondered where the hooks are. Turns out they are hidden within the ends and can be either extended or retracted. The next puzzle was to find the port for charging, it is hidden on the end of the light and you need to rotate the hook to expose the opening. I show it in the video, as it is easier to show than describe. When the light is charging you red LED light is on, when the charging is done the red LED is turns off. The manufacture recommends not leaving the light charging continuously.



Overall, I am very pleased. Good amount of light and it can be mounted in many different ways.

Product review: YOTOSAN Smart 16-Outlet Home Vertical Power Strip



This outlet tower fits perfectly behind my computer. I don't have a lot of room there and need a lot of outlets - both AC and USB powered - and this tower is perfect in that space. There are 15 AC outlets and 2 USB outlets. The AC outlets are well spaced out. I am able to mount two large chargers next to each (see video), no outlets are blocked! This is a very clever design.



The two feet power cord can be coiled in the base of the tower and I can release only what I need. This reduces the cord jungle I have behind the computer.



I tested each USB port with a current monitor an Android device and an Apple device. Both ports are 1A ports. They charged my Android devices at the optimal rate, and my Apple devices below optimal (since they need more than 1A to perform at the optimal rate). I do my tests with the devices charged to the same level, running the same applications and using the same cables to keep everything the same. This allows me to compare them to each other in a fair way. I use the current monitor to see what current is delivered to each device which tells me how well each external battery is working.



Samsung Nexus phone:

~~~~~~~~~~~~~~~~~~~

1 port: 0.97A/5.03V (excellent)

2 port: 1.01A/5.01V (excellent)

(for comparison the best charging monitor result for this phone is 1.00A/5V)



iPad Mini tablet:

~~~~~~~~~~~~~~~~~~~

1 port: 0.93A/5.02V (average for 1A)

2 port: 0.93A/5.01V (average for 1A)

(for comparison the best charging monitor result for this tablet is 1.70A/5V)



I love the shape of this power strip, it gave me more than enough outlets in the area which barely has any space.

Product review: Koch Dimmable "Book" LED Lamp



Update: In about 1 months the book light stopped working. I am no longer able to charge it. Even if I charge it for 24 hours it does not turn on.



Original 4 star review follows. The rating has been changed to 1 star.



This is a neat looking light. I saw a similar looking product on Shark Tank but this one is made by a different company. When closed this light looks like a book, when opened it provides light with an option of having 4 different colors. The intensity of the light is not dimmable, but each color provides a different level of lighting. The white light is the brightest but it is still not bright enough to read under. I would classify this light as a night light or a mood light. In my video I show the light in various configurations. I also show the reading of the lux meter which measures the intensity of the light.



The lux meter right next to the light shows 519 lux.

The lux meter at 12 inches shows 49 lux.

For comparison a 60 watt light at 12" produces a reading of 1110 lux.



The light is charged with a regular micro USB cable. When it is charging the light next to the port is blue, when it is fully charged the light turns off.



After I fully charged the light, I turned it on timed how long it stayed on. The light stayed on for 12 hours. It took 5 hours to fully recharge it.



This is a fun novelty light and a good looking night light.

Product review: Balichun Supreme Collection - High Quality 100% Cotton 4-Piece Bed Sheet















Balichun cotton sheets have a tight weave and a smooth finish. Detracting from the fine fabric is the finish of the seams that has a lot of hanging threads. The seams don't seem to be unrevealing (the sheets have been through two washes as I write this review) but the stitching is little sloppy. I show an example in attached photo.



I like:

~~~~~~~~~



1. Tight weave

2. Smooth sateen finish, very nice to touch

3. The fitted sheet has an elastic all the way around (not just two sides like some sheets) this results in a very good fit regardless of the size of the mattress. The pocket size is 14". Our mattress is 11". However because of the good elastic I get a very nice tight fit which is not always the case with 14" pocket and a thinner mattress.

4. Simple but elegant edge decoration. It appears on the pillow cases and on the flat sheet. I show a close-up in my photos



I don't like:

~~~~~~~~~~~~~~

1. Not wrinkle free straight out of the dryer

2. Workmahip of the seams, they have a lot of dangling threads



Overall, even though not perfect this is a very nice sheet set and after sleeping on it for a couple of weeks I give it thumbs up.

Product review: Kinps 20000mAh Portable Power Bank





















' size: 8.25" x 5.5" x 1.5"

' weight: 1 pound

' number of ports: 3 universal ports

' flashlight: no

' cables: 1 charging cable



This external battery performed very well charging both my Android phone and Apple iPadMini tablet. Each port of this battery is universal, i.e. each of my devices does equally well on each port.



To see how well different chargers and external batteries charge my mobile devices I use a Nexus phone and an iPadMini to test each of them. The current drawn from the battery depends on each device using the battery. The port rated with maximum capacity of 2A does not always deliver 2A, what is actually delivered is controlled by the device based on many factors such running apps, level of charge, and so forth. I always use the same two devices and I do my tests with the devices charged to the same level, running the same applications and using the same cables to keep everything the same. This allows me to do a relative comparison of each battery and identify the ones that do not perform well. Note that these tests are not testing for the maximum current each device can draw on each port as neither of my devices can max out the port.



I check if the cable that came with the battery is a charging cable (i.e. capable of charging at full AC rate or if charges at slower USB rate). This is easy to tell by using a current monitor and I happy to report that this package includes a charging cable that works at AC rate.



Samsung Nexus phone:

~~~~~~~~~~~~~~~~~~~

port 1: 1.02A / 5.10V (excellent comparing the performance of the same device with other chargers)

port 2: 1.02A / 5.09V (excellent comparing the performance of the same device with other chargers)

port 3: 1.02A / 5.10V (excellent comparing the performance of the same device with other chargers)

(for comparison the best charging monitor result for this phone is 1.00A/5V)



As noted above these tests are not designed to test the maximum capacity of the port, so 2A port not showing 2A is not an indication of a problem



iPad Mini tablet:

~~~~~~~~~~~~~~~~~~~

port 1: 1.23A / 5.08V (good comparing the performance of the same device with other chargers)

port 2: 1.15A / 5.09V (good comparing the performance of the same device with other chargers)

port 3: 1.35A / 5.10V (good comparing the performance of the same device with other chargers)

(for comparison the best charging monitor result for this tablet is 1.70A/5V)



The battery has a nice capacity and fast charging rate for oth Android and Apple devices. I use it to power a 4" speaker which is used several hours a day and it runs for many days without needing a recharge.
