Product review: Axgio PowerSlot L6U Desktop Wall USB Charger


♦ size: 2.5"W x 2.5"L x 3.25"H
♦ weight: 6.45 oz
♦ number of ports: 6

This wall charger does not work well in a wall outlet. It is bulky and heavy and it fell out of the wall outlet on several occasions. It is better used on an extension strip so that the charger can be plugged in with the prongs down.

This charger is designed for input AC100-240V and can work in US as well as internationally. It comes with a removable US plug. It would have been really nice if it had multiple plugs so an American buyer could use this plug while travelling.

This charger has 6 ports. Two of the ports are labelled as 1A outlets, the remaining 4 outlets are paired together and provide shared 2.4A between each 2 outlets in the pair. What does all this labelling mean in practice? To answer this question I used a current monitor abd checked how much power each port on this charger provides to my devices. I use a Android Phone for each optimal charge is 1A / 5V, and iPad Mini for which the optimal charge is 1.70A / 5V. I test all my chargers this way using the same charging cables, running the same apps while charging, and starting all tests at same charge level of the phone to account for non-linear charging. This allows me to compare the performance of different chargers to each other keeping everything else constant.

I tested each device on each port one device at a time, as well as with several devices charging at the same time, especially using those shared power ports. I am including detailed results below. For those who are interested in a quick summary I found this charged worked with both devices but charged both at slightly below optimal rate.

Samsung Nexus phone:
~~~~~~~~~~~~~~~~~~~
Port 1: 1.02A / 5.14V (excellent)
Port 2: 0.92A / 5.14V
Port 3: 0.89A / 5.14V (below optimal)
Port 4: 0.94A / 5.14V
Port 5: 0.94A / 5.14V
Port 6: 0.88A / 5.14V (below optimal)

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

iPad Mini tablet:
~~~~~~~~~~~~~~~~~~~
Port 1: 1.23A / 5.13V (ok)
Port 2: 1.26A / 5.14V (ok)
Port 3: 0.92A / 5.14V (below optimal)
Port 4: 1.15A / 5.13V
Port 5: 1.12A / 5.14V
Port 6: 0.93A / 5.14V (below optimal)
(for comparison the best charging monitor result for this tablet is 1.70A/5V)

Test on 2.4A shared ports (port 3 and port 4)
~~~~~~~~~~~~~~~~~~~~~~~~~~
Nexus phone (port 5): 0.81A / 5.14V (slightly less when it was charged alone)
iPad Mini (port 4): 1.22A / 5.13V (slightly more than when charged alone)

I've done quite a bit of testing for this charger. The charger works and was able to charge multiple devices at once. However it is not among the fasterst chargers on the market, and it is not a "smart" charger that provides an optimal charge for any device on any port. The design is bulky and does not work well as a wall charger because it does not stay in the outlet. If the package included a set of international plugs I would have given me a reason to prefer it to some other charger which is not designed to work internationally. As it stands now it is okay, it works but has some short comings.

Product review: YOOBAO 31W 4-Port Desktop USB Charger


This unassuming looking charger works very well. It charged 4 mobile devices (2 tablets and 2 phones) at full AC rate and remains cool while doing it.

♦ The charger size: 4.875" x 3.25" x 1.125"
♦ The charger weight: 6.75 oz
♦ The AC cord length: 56"

I measured the chargers performance when it was charging 4 devices at the same time as well as one at a time. I used both an Apple device and an Android device and saw that both worked at very good rate. The Android devices work at optimal rate on all 4 ports and iPad Mini worked at at optimal rate on the two 2A ports and below optimal on the two 1A ports (this is expected, as Apple devices need more than 1A to charge at full rate). I am including the detailed current monitor readings below for those who like to see the technical details.

➨ Test results
======================
--------------------------
✔ Samsung Galaxy Nexus Phone (the only device charging)
--------------------------
Port 1: 1.03A/5.07V
Port 2: 1.03A/5.06V
Port 3: 1.03A/5.07V
Port 4: 1.02A/5.07V

--------------------------
✔ Samsung Galaxy Nexus Phone (with 3 other devices charging)
--------------------------
1.03A/5.05V
--------------------------
✔ iPad Mini (the only device charging)
--------------------------
Port 1: 0.93A/5.08V
Port 2: 0.92A/5.08V
Port 3: 1.32A/5.08V
Port 4: 1.34A/5.09V

--------------------------
✔ iPad Mini (with 3 other devices charging)
--------------------------
1.32A/5.08V
--------------------------

To summarize this charger did well charging my 4 devices at the same time. It perform at optimal rate for Android devices on all ports. It worked well on 2A ports with iPad Mini.

Product review: Yubi Power Desktop Power Charging Station - 2 USB Ports and 3 AC Outlets


This charging station has a 47" inch AC cable, 2 USB ports, and 3 grounded AC ports. The station has a retractable tray stand for the phone. The tray is a bit sticky at first, so it takes a little force to open it for the first few times. The tray is on the opposite side from the AC outlets. I include the video of opening it in my video. The charging station size is 4.625" wide x 3" tall and 3.375" front to back when the tray is extended, and 2.75" front to back with the tray retracted.

Two AC outlet are positions close to each and accept regular size plugs, one is spaced out enough to accept a large plug. However a battery charger such as SONY Eneloop does not fit because there is no enough room to extend beyond the outlet.

I measured the performance of the 4 USB ports. I used both an Apple device and an Adroid device. I tested each device when it was the only one charging on each of the ports, as both of them charging at the same time. Both devices worked, the performance for my iPad Mini was very good, but the performs for my Android phone was below optimal. I am including the detailed current monitor readings below for those who like to see the technical details.

➨ Test results
======================
--------------------------
✔ Samsung Galaxy Nexus Phone (the only device charging)
--------------------------
Port 1: 0.89A / 4.95V
Port 2: 0.87A / 4.95V

--------------------------
✔ iPad Mini (the only device charging)
--------------------------
Port 1: 1.43A / 4.95V
Port 2: 1.42A / 4.90V

--------------------------
✔ iPad Mini and Samsung Galaxy Nexus Phone at the same time
--------------------------
Nexus phone - Port 4: 0.79A / 4.95V
iPad Mini - Port 3: 1.59A / 4.95V
--------------------------
Nexus phone - Port 3: 0.76A / 4.95V
iPad Mini - Port 4: 0.95A / 4.95V
--------------------------

To summarize I like that the charging stations combines USB and AC ports without an additional charger. However, USB ports on this charging station did not perform as well as the other chargers for more Android phone. If you have Apple devices this is a no brainer good charger. If you have an Android devices it is not as clear cut. The decision here is between the convenience of having a charging station and relatively slower speed of charging. I am using this charger to charge the speakers attached to my TV rather than to charge my phone and I always can use a couple of extra AC outlets near the TV. Because the phone holder is retractable it does not take up any room when it is not used.

Product review: Samergy Bladeless Fan - 14 Inch


I love this fan! It blow air evenly (not in puffs like a regular fan) and the noise it makes is uniform not changeable like a fan with blades.

The air comes from a circular tube mounted on a pedestal that houses the motor. The "bladeless" name is a bit of the misnomer. There are no visible blades but the fan does have blades hidden inside of the base. There is a small internal fan that pulls air into the base and the motor pushes it into oval and through the slits of the oval. When the air escapes from the slits in the oval the air behind the oval is pulled through the oval as well and this increases the amount of air that the fan pushes forward. This fan works on this basic law of physics, the fluid dynamics. Pretty cool!

The fan is 22" tall, and the oval is 14.5" top to bottom. The fan comes with a remote control which allows me to turn it on and off, increase and decrease the air flow, make oscilate side to side, and turn on LEDs at the bottom of the base. I captured all these options in the attached video.

The fan is not silent the the noise is white nose because it is very regular. I am light sleeper and find it less noticeable than the noise of a regular fan with blade which generates noise that is less steady.

Product review: Yubi Power Power Strip Surge 4 port USB/4.8A and Dual Plug100-240V



This power strip has a 5 foot AC cable, 4 USB ports, and 2 ungrounded AC ports.

AC outlet positions in a way that they will accept two large plugs, but not two battery chargers (such as SONY Eneloop).

I measured the performance of 4 USB ports. I used both an Apple device and an Android device. I tested each device when it was the only one charging on each of the ports, as well as it was one of 4 devices charging at the same time. Both devices worked, but the performance was a bit disappointing for my Android devices on all 4 ports (AC rate but significantly below optimal), and good for Apple devices on two ports, and below optimal on two other ports. I am including the detailed current monitor readings below for those who like to see the technical details.

➨ Test results
======================
--------------------------
✔ Samsung Galaxy Nexus Phone (the only device charging)
--------------------------
Port 1: 0.78A / 5.07V
Port 2: 0.74A / 5.06V
Port 3: 0.71A / 5.07V
Port 4: 0.70A / 5.07V

--------------------------
✔ Samsung Galaxy Nexus Phone (with 3 other devices charging)
--------------------------
0.66A/5.08V
--------------------------
✔ iPad Mini (the only device charging)
--------------------------
Port 1: 1.36A / 5.08V
Port 2: 1.32A / 5.08V
Port 3: 0.92A / 5.08V
Port 4: 0.92A / 5.09V

--------------------------
✔ iPad Mini (with 3 other devices charging)
--------------------------
1.39A/5.08V
--------------------------

To summarize I like strips that combine USB and AC ports without an additional charger. However, USB ports on this strip did not perform as well as other chargers for my Android phone, it charged but below the optimal rate. On the other hand this power strip did very well on 2A ports with iPad Mini.

Product review: Hoont Plug-in Electronic Total Pest Eliminator


Between 1985 and 1997 FTC brought a law suit against six companies making false and unsubstantiated claims about the effectiveness of ultrasonic devices in controlling rodent and insect infestations. In 2001 FTC sent warning to more than 60 manufacturers stating that their claims are not supported by scientific evidence.

FCC commission document states that ultrasonic pest control devices cause radio frequency interference to television reception in the 20-470 MHz range.

The instructional booklet or packaging do not state what the level of ultrasonic sound the Hoonts device produces. It only states that it is safe for pets. I contacted the manufacturer 2 weeks ago but did not receive this information thus far.

UPDATE 11/14/14: The day after this review was published I received an update from the manufacturer. "The unit works on 35-45KHZ with up to 130dB." He also stated that "Ants might be deterred not by ultrasonic waves, but by electromagnetic waves use the wiring of the house."

I was able to test two things:

1) Does the device emit anything?
I own a sound meter which measures sound decibel levels (it is not a sound analyzer so it does not Hz). I was able to measure that if I turn on the device I can see that decibel level change, so at least I was able to measure that Hoonts device produces ultrasound waves.

2) Do the pests react to it?
I am interested in getting rid of ants which I occasionally see trotting around in my basement. Outside, in my rock garden, I have a small ant colony. I decided to test if my local ant colony will react to the device. In this test I did not expect to get rid the ants, I just wanted to see if they had any reaction. If they did not like the sound, I expected them to change their normal speed and path. I plugged the pest repeller into an extension cord and took it outside to point at the ant colony. The ants had absolutely no reaction. They continued walking slowly at the speed and in he same direction.

I was puzzled that my ants did not react to the device and did a bit of research on insects and ultra sound. I found that some insects use ultra sound as part of their mating behavior. So it is possible that my worker ants just don't have receptors for ultra sound and the device will only work on the queen and her drones during the mating period.

There is a great range of opinions on whether ultrasound repellers work. One needs to read the reports carefully to screen out biased opinions. Pest Control companies often say it does not work and a pest control company provides better results. Studies sponsored by ultrasonic repeller manufacturers state they are effective. Studies from universities which appear to have less bias report mixed results. They show that some pests are effected for a period of time but then return. They also report different results from different products, which is also not surprising since they maybe producing different frequencies.

Here are some references from people which appear not to have a bias one way or the other because they are doing university studies and the last is from a retired entomologist.
1. Askham, Leonard R. "Ultrasonic and Subsonic Pest Control Devices." Washington State University.
2. "Electronic Mosquito Repellents Don't Work, Say Researchers." ScienceDaily
3. Ogg, Barb. "Considering Ultrasonic Pest Control Devices? Save Your Money." University of Nebraska-Lincoln.
4. DeAngelis, Jack. "Electronic/Ultrasonic Pest Repellers." LivingWithBugs.

So what's the bottom line? Based on unbiased experiments this device might work for some pests but only temporarily. The same is echoed in the FTC statement. FTC complaints alleges that any reaction by rodents to ultrasound would be temporary at best because rodents become accustomed to ultrasound and will return to their nesting or feeding areas even in the presence of an ultrasonic device.

I received this repeller from Hoonts for an honest review, be it positive or negative.

Product review: Block Financial H&R Block Tax Software 14 Deluxe + State (TaxCut 2014)



I've used H&R Block's tax software (formerly called TaxCut) every year since 1995. Several times when I saw a promotional deal I purchased both H&R Block and TurboTax to compare. I found that both programs satisfied my needs but TaxCut costs consistently less. I have been buying the Deluxe version of H&R Block, before purchasing I check to see if my needs are covered by the feature set of Deluxe version. The main thing I check if the mutual funds sales and cost basis calculations are included (Schedule D) and the form for Foreign Tax Credit from mutual funds is present (Form 1116). H&R Block Deluxe version includes these forms but to get this functionality in TurboTax you need to buy the Premium version of the software.

✔ INSTALLATION
~~~~~~~~~~~~~
♦ I had no problems with my install. However last year I helped a friend resolve an install problem on a Windows 8 PC. I am including what we did in case this helps someone else. Normally the automatic install runs a file called "tcauto.exe". This file in turn calls another program located under "installers" directory which actually does the work. We were able to by-pass the error my executing the exe program in the installers directory directly "HRBlock_Deluxe+Efile+State_2014_CD.exe" (it is the only file in that directory).

♦ If you encounter issues with display, such as not seeing selection boxes, check your screen resolution. Both Windows and Mac minimum requirement for the screen resolution is 1024 x 768 pixels or higher. At a lower resolution H&R Block software will have problem with display such as not properly displaying selection boxes. Screen resolution can be changed on your control panel by change PC's display settings.

♦ If you are using a digital download you will need a key-code to install the software after you dowload it. The key-code can be located two ways.
Option 1: After my download finished the install started automatically offering me a choice of two links "View Keys" and "Install".
Option 2: You can locate it in your Amazon account:
1) Log into Amazon
2) Select Your Account at the top right of the page
3) Select Games and Software downloads which is towards the bottom of the long page you see when you log in
4) Then under H&R software entry you will see the key-code that you need to enter to unlock the software

♦ Does H&R allow to install the software on two PCs?
I found the answer on H&R Block web site FAQ under the topic "Installing Software on Another Computer"
I quote the FAQ answer below:
"There are just a few steps necessary to re-install the H&R Block At Home program from the CD you received in the mail. Follow the steps below to re-install the program or install it on a second computer.
Insert the H&R Block At Home CD into your computer.
Click the Need to Re-install? link on the menu bar at the bottom of the screen.
The Frequently Asked Questions page will open to the first FAQ titled, "Can I install the software on a second computer?"
Enter your activation code and last 4 digits of the credit card you used to purchase the program initially and click Activate.
You can find your activation code in your purchase confirmation e-mail.
Follow the on-screen instructions to complete the installation."

✔ WHAT IS INCLUDED
~~~~~~~~~~~~~

I purchased H&R Block Deluxe plus State. This version entitles me to 5 free federal e-files. It allows me to print and mail as many returns as I want, there is no limit on printing.

One state software is included in the package but the package does NOT include free e-file for the state return (see one exception below). If you want to e-file your state return you will need to pay a fee of $19.95 to e-file each state return. Alternatively, you can print all the forms and mail them using US post office. If you need to file taxes for an additional state, each additional state is $39.95 plus $19.95 e-file fee.

Note: NY state residents can e-file state returns for free.

✔ GENERAL
~~~~~~~~~~~~~

I just finished my preliminary tax return and below are my observations. Note: the forms are not final until mid January of 2015.

♦ Pet Peeve: H&R Block starts the interview process with an annoying up-sell pitch, recommending an upgrade from Deluxe to Premium even when it is not necessary. In my opinion, they should wait until the person enters this year's data and suggest the upgrade only if there is something about the return that can benefit from the Premium version. That would have been useful.

What is the difference between Premium and Deluxe? The Premium version offers advanced tools for self-employed and rental property owners: cost basis of home sales, dividends, gifts, and inheritance assets. It has advanced schedule C guidance to maximize deductions for self-employment income. And finally it has guidance for rental property income and expenses. The rest of the Premium package is the same as Deluxe.

Note that the Deluxe package has support for self-employed income as well as stock sale cost basis calculations. Last year I had to do both and I found the guidance in Deluxe package was sufficient to complete the forms.

♦ Pet Peeve: Help is not context sensitive. For example, when you click on "learn more" about a particular topic the general help window opens but it does not show help topics for the specific topic that you were working on. Instead you need to search and know which key words to use locate the relevant topics.

♦ H&R Block provides you some guidance for completing Form 1116 (foreign tax credit, for example foreign tax paid by mutual funds). However, you need to keep switching between whole-form view to enter data and then back to interview to read the instructions. Even though the form where you can enter data is visible at the same time as instructions you cannot enter data into it until you switch into whole-form view. This is cumbersome, but at least there is some guidance for this form.

♦ DeductionPro (which helps you put value on your charitable donations) is integrated into H&R Block software running on your local PC. You no longer need to enter this information on H&R web site. I prefer having this information locally on my PC for better security. The change from web site to local PC was introduced last year and I was happy to see that this change is here to stay.

♦ Pet Peeve: I don't use the default location for the tax returns due to how I set up my backup software. The H&R Block software does not initially remember this new location on the second start of the application, it told me I have no returns. I needed to pick the return manually from the File menu, as it did remember recently used files. The third time I started the software, it finally knew the location of the tax return file.

♦ I usually purchase tax software as early as possible to help me with end year tax planning. However, if timing is not important to you be aware that the price on this package changes often and you can catch some great discounts. I use a nice tool that shows history of Amazon prices. If you enter "Amazon price history alert" in Google it will come up at the top, my favorite has the word camel in the name. You can set up the tool to send you an alert when you desired price drop is reached. During the last tax year season the price fluctuated between $20 and the list price of $44.99, and was on the gold deal special a couple of times.

♦ For folks trying to download State Forms. The state forms are not available as of 11/30/2014. You have an option of entering email where you will be notified as soon as the form for your state becomes available. Alternatively, you can go to H&R website, hover (do not click) "Download Software" on the top banner and select "State Editions". Currently it says "Please check back in mid January 2015".

When the state forms will become available they can be downloaded by selecting the State Tab and then clicking on the button labelled "Buy" (a little scary since we already paid for it) but then "buy" will turn into "update" and the forms will be downloaded to your computer.

♦ At the end of the interview process there is a check step (which you can run at any time, but the interview ends with this check). This step flags problems (e.g. missing information) and potential audit alerts (e.g. unusual deductions) with red flags, and reminders (e.g. things you marked tentative) with yellow flags.

♦ Sometimes I want to return to some section of my return. The best way to jump to any section directly without navigating through other pages is to use "take me to" button which is displayed at the top of every page, on the same line as H&R Block banner.

♦ Does H&R has the ability to import TurboTax data from previous years?
Yes. TurboTax files have a .tax extension. Use the Browse button within H&R Block application to navigate to the folder you need and it will import the data from TT return.

I have been a H&R Block/TaxCut user for many years. I keep coming back because it works well for the tax forms I need to do and it is less expensive than TurboTax. If you have a question I have not covered leave a comment and I will do my best to answer it.
