My Avantree CGTR-520-W desktop power station with 5 USB charging ports and 2 AC outlets

You've probably read about my Belkin B2E027 4-port 2.4A full rate USB power charger before. It is still working fine and I am still using it.

Recently, I discovered something even better, which is the Avantree CGTR-520-W desktop power station. It comes with 5 smart USB ports, which each single port able to charge up to 2.4A and the total combined charging capacity is 8A.

It also comes with 2 AC sockets (maximum 10A loading) with surge protector of 1,700 Joule and power rating of 1,250W (for 125Vac) or 2,250W (for 225Vac).



You've probably seen it in action when I talked about my KCX-017 USB current and voltage tester in my previous post.

This power station is handy when you have limited wall sockets, as it won't occupy your wall socket and at the same time it extends another socket for your use. You can use its sockets to charge your laptop and other bigger devices that need to be charged with electrical socket instead of USB.

My KCX-017 USB current and voltage tester

Sometimes you will face problem with USB charging such as charging speed slower than normal, unable to charge, or worse still, you encountered a "reverse charging" whereby current is drawn away from the battery of your device instead of charging it.

The problem could be due to faulty charger, faulty USB cable, or faulty USB port of the device to be charged.

In addition, certain 3rd party USB cables are having quality issue with unstable current flow, or only allow low current flow through it.

A USB tester such as the KCX-017 will be handy to diagnose such situations.


This small gadget only cost around RM25, and works well with wall charger, car charger, power bank, etc. by connecting its attached USB cable to the charger, or by connecting the charging cable to its micro-USB port. It will measure the input voltage and display on its LCD screen.

Its other end is a USB port which you can use a USB cable to connect to a charging recipient such as mobile phone, tablet, GPS navigator, etc. Beside the voltage, it will also measure and display the current drawn by the recipient, and also calculate the mAh value of the charging session.


In summary, this gadget is used to:
  • Test no-load voltage of the power supply
  • Test output power of USB output devices
  • Test working voltage and current of the USB output devices
  • Test voltage and line loss of charging cables
  • Perform real-time monitoring of the charging status

Its specified working environment is as below:

  • Voltage range: 3-7V
  • Current range: 50mA-3,500mA
  • Capacity range: 0-19,999mAh
When the input voltage is lower than 4.7V or higher than 5.3V, its LCD screen will flash with an arrowhead indicating under-voltage or over-voltage.

This device can record up to 10 sets of readings. There is a button near to its LCD screen.
  • Double click the button, the display will start flashing. Single click the button to switch to different memory slot (from 0 to 9). Double click again to use the current memory slot displayed on screen.
  • Long press the button will reset the next memory slot reading back to 0000.
This device is able to memorize the last reading when unplugged. The next time when it is turned on again, that reading will be displayed on its LCD screen.

It is a handy device to troubleshoot USB charging problem, as well as to test for the charging quality of USB cables.

My VST-706 3-in-1 car battery voltage monitor, digital thermometer and USB charger

I have just bought this VST-706 car gadget which plugs into the car cigarette lighter socket and function as 3-in-1:

  • Battery voltmeter
  • Digital thermometer
  • USB 2.0 charger

This little car gadget cost less than RM30 and works with car using 12V battery or 24V battery.

The interpretation of its voltmeter reading is as follow:


Its thermometer measuring range is -9 ~ 80 degree Celsius.

The maximum output current of its USB charging port is 2.1A.

With it, you can always monitor the voltage of your car battery and be alerted of its faulty and timing for its end-of-life, before it went flat. The thermometer and USB charger are extra features that good to have too.

My SanDisk Ultra Dual USB Drive 3.0

The price of USB flash drive has eventually gone cheap. Nowadays, you can get a genuine 16GB SanDisk Ultra dual USB drive 3.0 with plug-and-play support to OTG-enabled Android devices at the price of less than RM20.


This SanDisk Ultra dual USB drive 3.0 has 2 connectors. At one end is a USB 3.0 connector that is able to transfer file to computer at a speed of up to 130 MBps (or about 1 Gbps).

Note that there is another product called "SanDisk Ultra dual USB drive" without the "3.0" behind, selling at slightly cheaper price, which the USB connector is a USB 2.0 connector and the data transfer speed is much lower than the 3.0 version.


At the other end is a micro-USB connector that can work on the fly with OTG-enabled Android devices.


Similar with the warranty period of most SanDisk Ultra range of products, this SanDisk Ultra dual USB drive 3.0 comes with a 5 years warranty.

Once plugged into the micro-USB port of the Android device, this USB flash drive is auto-detected by Android as one of the external storages and is immediately accessible by File Manager of Android system.

SanDisk also provides a free mobile app called SanDisk Memory Zone for user to access the USB flash drive and to transfer file between it and the device's internal storage or flash memory card installed in the device.

However, I found the function of this SanDisk Memory Zone app is very limited. It doesn't work with the folders in the USB flash drive so you can only copy file to its root directory, and the copying process is pretty slow.

The only Android app I found that can work with it without hassle is ES File Explorer Pro (or its free version ES File Explorer).

ES File Explorer Pro is able to detect and use this OTG drive upon plugged in, and all file operations of copying, moving, renaming, deleting, creating, opening with associated app, etc. can work well without problem.


ES File Explorer Pro works equally well to access my SanDisk Ultra Dual USB Drive 3.0 with my HTC One M8 smartphone running on Android 6.0 and my Samsung Galaxy Note 5.0 tablet running on Android 4.4.2.

Warning! Touch n Go cards must be used at least once per year, or you will lose money!

Perhaps not many people aware that their Touch n Go card, if stayed unused for 12 months consecutively, will be deactivated and suspended into dormant state.

The dormant card cannot be used anymore, and your money balance in the card will be locked and rendered unusable, until you get Touch n Go to reactivate the card.

There is an admin fee of RM5 plus GST (total: RM5.30) to reactivate the dormant Touch n Go card.

If you continue to keep the card staying inactive, they will still charge you RM5 plus GST (total: RM5.30) of maintenance fee in every 6 months interval. The maintenance fee will be deducted from the balance in the dormant card, until it reached zero. Then, it becomes a junk plastic card.

In addition, every Touch n Go card has a lifespan of 10 years only, and the expiry date is printed behind the card.

Upon expiry, you can buy a new card and transfer your balance from your expired card into your new card. There is an admin fee of RM5 plus GST (total: RM5.30) for Touch n Go balance transfer too.

Today, there are several highways in Klang Valley that no longer receive cash as toll payment and made compulsory to pay with Touch n Go.


If you are staying outside Klang Valley and were forced to buy a Touch n Go card just to pay the toll during your visit to KL once in a blue moon, you are likely to be affected by this.

According to Touch n Go, you can avoid this situation by using the Touch n Go function in your MyKad instead of purchasing the standalone Touch n Go card. Your MyKad will not become dormant even if you don't use it as Touch n Go card for more than 1 year.

About Private Retirement Scheme (PRS) and its funds performance at end of April 2016

Launched in 2012, the Private Retirement Scheme (PRS) is a voluntary (non-compulsory) retirement scheme in Malaysia for employees and also self employed to have another option of forced saving for their retirement.


In order to encourage savings under PRS, Malaysian government granted personal income tax relief of up to RM3,000 for individuals tax payers from their PRS savings amount deposited during the taxation year. 

Employers are also provided with tax deduction on contributions to the PRS on behalf of their employees above the statutory rate of 19%.

Note that this income tax relief for PRS is available for 10 years only, from tax assessment year 2012 until 2021.

Also note that the sales and admin charges deducted from your PRS contribution is not eligible for tax relief, you can only claim the amount from your net PRS contribution done within the year, up to RM3,000 per year.

Your PRS contributions will be deposited into your Private Pension Administrator (PPA) account, after your PRS fund provider deducted the sales and admin charges.


Your money in your PPA account is split into 2 sub-accounts (a bit similar to your EPF account). Once your money is parked in your PPA account, you can forget about it until you finally retire, because:
  • 70% of your fund is parked in Sub-account A, which cannot be withdrawn until you retired.
  • 30% of your fund is parked in Sub-account B, which you can only withdrawn once a year, and subject to an 8% tax penalty on the withdrawal amount.
Your money in PPA account is then allocated for investment by your fund manager with your selected fund scheme, which could be of category of growth, moderate or conservative.

There is no guarantee that your PRS fund will give you return. In fact, you can also lose money if your fund is not performing!

How is the performance of the available PRS funds so far?

Morningstar is tracking the PRS funds performance (there are 79 of them as at 30 April 2016) on a day-to-day basis.

As of today (30 April 2016), only 19 or 24% out of the total 79 PRS funds have made a positive year to date return. AmPRS - Asia Pacific REITs is the champion with 4.79% return YTD.

Those 19 PRS funds that have positive return year to date, and their YTD return are as below:

(Screen captured from Morningstar's PRS fund performance tracking website, double click on image to enlarge)

The worst PRS fund performer YTD, CIMB Islamic PRS Plus Asia Pacific Ex Japan Equity fund, has caused a 8.92% lost in 4 months time.

Anyhow, YTD return is for monitoring of latest return performance of the funds. If you see your fund continuously not performance well over a couple of months, you should consider switching over to another fund that is performing well over the same period of time.

Now, let's look at their full year return in 2015. There are a total of 75 PRS funds active in year 2015, and 74 of them had brought positive return, only 1 has lost money.

The champion in 2015 is AmPRS - Islamic Equity Fund with a return of 16.3%. The top 10 PRS funds in 2015 are:


And the bottom 10 PRS funds in 2015 are:


So, does it worth to lock down your money in PRS, and put it in the hand of your PRS fund managers to bring return or lost to you? You decide.

Earth Day and the story of bottled water

We've just celebrated our Earth Day on 22nd April. This event has once again brought some world attention to the story of bottled water, with a video produced back in 2010.

Here is the video, which has been viewed over 4.7 millions time in YouTube:


So, what's wrong with the bottled water? It is a multi-billion business, sold 290 billion liters in 2014 and expected to continue growing at a CAGR of around 8.5% between 2015 and 2020.

Well, we are told that about half of the bottled water is sourced from tap water, and priced a few hundreds time the price of tap water. It is expensive, sometimes even more expensive than petrol.

Another half is sourced from underground or spring water. What will be the impact to the environment when millions of gallons of water is extracted away 24x7 everyday? Will it change the soil moisture, deplete the wetlands and narrow out the rivers? Will it in turn affect the surrounding ecology, and the aquaculture and agriculture condition?

Anyhow, the main issue is more on the plastic bottle itself than the water contained in it. In order to manufacture the plastic bottle, millions barrels of fossil fuel is consumed, and another millions tonnes of carbon dioxide is generated.

Each year, more than 4 billion pounds of PET plastic bottles end up in landfills or as roadside litter, or worse still, floating in the sea endangering the birds, fishes and other ocean animals. Only less than 20% of plastic the water bottles are actually recycled.
In the United States of America, selling of bottled water is banned in more and more schools and colleges, and even parks.

Therefore, to save our earth and its environment, we should only drink bottled water when necessary, and not to substitute our daily drinking water with it. We should resume our traditional way of drinking filtered or boiled tap water, and use reusable water container to carry some water with us for outdoor drinking.

Negative interest rate - get paid from borrowing and get charged from saving

If you think that you can earn some interest by depositing your money in bank, and you will be charged with interest for borrowing money from bank, you have to reverse your mind-set in certain places that are having negative interest rate policy now.

I'm not kidding. The European Central Banks (ECB), Switzerland, Denmark, Sweden are already having negative interest rate for quite some times. Lately, Japan has joint the league too!

(Chart produced by Toronto Star)

The ECB started this game by charging banks that hold their cash overnight and at the same time offering a premium to banks that borrow in order to extend more loans.

During economic uncertainty time, people tend to be conservative with spending and/or investing and more keen to hoard money in their bank accounts. They are willing to do so even with zero interest rate. This brings the danger of deflation, and as an extreme measure to counter this situation, the banks started to "punish" people that keep money in their bank accounts by charging interest instead of giving interest, and to encourage people to take up loan for business and investment activities by giving interest instead of charging interest.

When this negative interest situation occurs, the traditionally safe havens to put your money, namely bank deposit and bond market, will become the places that most likely cause you to lose money. Yes, fixed deposit is dangerous, bond market is dangerous, because your money will go down the drain if you put it there, in the era of negative interest rate.

However, this measure doesn't seem to be effective to stimulate the economy, as people there are still very cautious and tend to hoard with their money. With the negative interest rate, they are forced to take out their money from bank deposit account, and then they are keeping the money in their drawer or safe instead of spending it. (Reuters: Negative ECB rates fuel demand for safe deposit boxes, German banks say)

The impose of negative interest rate in Eurozone and Japan has shown unfavourable sign of worldwide economy. What will be next after quantitative easing and negative interest rate? If there is no more option ahead, we can foresee a huge economic catastrophe forming and will hit all of us at anytime.

Are you prepared for it? And the question is: how to get prepared for it?

Income tax declaration of property rental - which expenses are deductible and which are not?

For most property owners in Malaysia who rented out their property, the rental collected from tenant is regarded as a non-business source of income and therefore is charged to the owner's income tax under section 4(d) of the Income Tax Act, 1967.

The amount of property rental income need to be declared is the gross rental income deducted by certain expenses incurred by the property in order to generate the rental.

The expenses that are income tax deductible including:

  • Assessment
  • Quit rent
  • Property loan interest
  • Fire insurance premium
  • Expenses on rental collection
  • Expenses on rental renewal, including the stamp duty
  • Expenses on repairs and maintenance
  • Expenses on replacement of rental assets
  • Property service charges, maintenance fees, sinking fund, and Indah Water bills
  • Legal expenses on renewal of tenancy agreement, recovery of rental arrears, etc. 
  • Expenses on pest control
  • Property agent fees/commission to renew the tenancy
The expenses that are not income tax deductible are initial expenses before the property is rented out, including:
  • Advertising cost to get the tenant
  • Property agent fees/commission to obtain the tenant
  • Legal cost and stamp duty for initial tenancy agreement
  • Expenses on renovation and improvement to get higher rental or to be more attractive to potential tenant
If the total rental income received is less than the total deductible expenses for the year, which shows that you have rental income loses instead of rental income gains for the year, then your taxable rental income for that particular year will be zero.

Note that rental income losses cannot be used to offset your other taxable statutory income of the year. The losses also cannot be carried forward to the next taxation year.

For more comprehensive information, you can refer to LHDN Malaysia Public Ruling No. 4/2011 : Income From Letting of Real Property.

WiFi technology - from Beamforming to MU-MIMO

Modern WiFi routers come with new selling features such as Beamforming and even MU-MIMO. What are these new features about? Will your home and/or office WiFi network be benefited with these new features? I also have the same questions, and here is the answer from my research.

Beamforming Technology

Beamforming is a kind of wireless transmission method introduced to reduce interference and improve the reliability of WiFi signal. It is adapted in the 5th generation WiFi standard 802.11ac.

Beamforming is based on Digital Signal Processing (DSP) logic and Multiple Input Multiple Output (MIMO) technology. Using a procedure called channel calibration or channel sounding, it changes the phase and relative amplitude of the signal, creating a constructive interference and destructive interference to make the signal in preferred direction stronger and others weaker.

In this way, the WiFi router can focus the signal towards the direction of your WiFi devices connected to it, making the wireless connection stronger, more stable, and further reaching. As effective WLAN bandwidth degrades with weaker signal and longer distance, beamforming can help to reduce this degrading effect, therefore making the network faster.

However, bear in mind that your WLAN network is still limited by the maximum supported bandwidth of the WiFi router and the WiFi client, and your Internet bandwidth is still limited by the maximum bandwidth of your subscription package. Your network still won't be faster than these limitation.

Certain 802.11n routers and devices also support beamforming, but unlike 802.11ac, there is no common standard with beamforming in wireless-N.

In order to benefit from the beamforming technology, both your wireless router and wireless device (computer, tablet, handphone, smart TV, etc.) must support this technology. If they are of wireless-N device, then the beamforming of the wireless client must compatible with the wireless router as well, preferably from the same brand or manufacturer.

Beamforming is standardized in wireless-AC, but that does not mean that all wireless-AC has this feature. You have to ensure your wireless-AC device comes with beamforming technology to get its benefit.

MU-MIMO

Traditional wireless router or access point, even with MIMO technology, can only serve one wireless client at one time. If it is connected to multiple WiFi devices, each of the devices take turn to be served. The more wireless devices you connect to the WiFi router, the less bandwidth is available for each one of them.
Multiuser MIMO (MU-MIMO) is introduced in the 5th generation WiFi standard 802.11ac. In a wireless system that uses MU-MIMO, the router can direct separate streams of bandwidth to up to 4 different devices simultaneously, as long as the devices are also able to use MU-MIMO technology.

For a MU-MIMO router with 4 antennas, each antenna can serve an individual MU-MIMO supported wireless device. Each of these devices can utilize the full WLAN bandwidth supported by the router.

If there are more devices, then the 5th onwards still need to share antenna with other device.

So, one MU-MIMO router is equivalent to 4 virtual MIMO routers, in the condition that the wireless clients connected to it also support MU-MIMO technology.

What if your wireless device is not supporting MU-MIMO? The router is backward compatible to act as single-user MIMO (SU-MIMO) router just like the older MIMO, and you won't enjoy the benefit of MU-MIMO in this case.

My MEC iPort G9000 PR1C 1HP portable air-cond

I have just purchased this MEC iPort G9000 PR1C 1HP portable air-cond last month for a small room in my house that is without wall mounted air-cond, and now the weather has become so hot that I feel this purchase was rally made at the right time.

MEC is a Malaysian brand. The size of this portable air-cond is in fact larger than my perception from its photo. It is quite thick, with the dimension of 458 x 745 x 348.

It looks stylish, with an automatic sliding panel that will completely cover up its louver blades outlet when it is turned off, to cover it from dust. The panel will automatically slide down when the air-cond is turned on.

This portable air-cond comes with quite a lot of accessories, including the standard accessory of remote controller with battery, and exhaust hose with wall exhaust adaptor. In addition, it also comes with window slider kit and 4 pieces of foam seal that can be applied to most vertical and horizontal windows. It also comes with a water drain hose for dehumidifying mode usage.

 
This portable air-cond has a modern look, with quite a lot of air filters, located behind it and also at its both sides. It has all the functions that you need, including the louver auto-swing feature, 4 selection modes of Auto, Cool, Dry and Fan, 4 fan speed selection of Low, Med, High and Auto, Sleep mode, Timer setting, LED display, intelligent self-diagnosis and auto-protection function, panel Lock function, auto-restart after power cut off, 3 minutes protection before resuming operation, etc. It makes use of the condensed water for cooling, evaporating the water during the process, therefore for normal operation with this self-evaporating system, it doesn't need to drain out water.

One unique feature is the Follow Me button on its remote control. In Follow Me mode, the remote control will send signal to the air-cond every 3 minutes, and the air-cond will direct the cool air to its direction. So, you just need to put the remote control beside you to get the breezing cool air blowing towards you.

This air-cond is pretty quiet during operation, and quite energy saving too. It has a current rating of 4.4A with 1000W power input, cooling capacity of 9000 Btu/h, EER rating of 8.9, airflow of 440 cubic meter per hour, which is equivalent to 259 CFM.

Overall, I am satisfied with this portable air-cond.

Ambidio - new audio technology that enables normal speaker to play super immersive surround sound that beats high-end 7.2 speakers

Ambidio is a new start-up in Los-Angeles founded by 29 years old Taiwanese girl Iris Wu and her friends, specialized in revolutionary sound technology. The company is backed by multiple-times Grammy award-winning artist will.i.am, and private investment arm of Hong Kong tycoon Li Ka-Shing - Horizons Ventures.

So, what's so special about this Ambidio technology? Well, it brings a high quality, immersive sound experience by just using computer software technology, which can instantly enable normal low-end speaker (preferably stereo) to play sound with effect of the standard as produced by expensive high-end surround sound systems.

Ambidio offers a new way for people to experience sound. It has a range that is at least 3 times wider than conventional methods that simulates three dimensional sound, using traditional speakers and headphones, allowing for a fully immersive experience.

Don't believe me? You can try yourself with this demo video provided by Ambidio, using your low-end speaker, and tell me what you think after listening to this 1 minute demonstration.


Ambidio has enlisted Lucasfilm’s Skywalker Sound, which has been redefining immersive sound for nearly 4 decades for film, TV and videogames, as a strategic advisor to assist with Ambidio's technology and creative development.

“Technology is transforming the way we experience music and, as an artist and producer, I’m always looking to what’s next – where the innovation is. Ambidio brings music to life through immersive sound, giving people a chance to experience music in a whole new way,” says will.i.am of his involvement.

The idea came about while music lover Iris Wu was attending graduate school at New York University, and was trying to create a quality listening experience but was dissatisfied with the results due to living in a small New York City apartment. She began experimenting with sound engineering through code rather than hardware and Ambidio’s technology began to take shape.

“The brain is a powerful mechanism that can interpret the directional origin of different sounds in everyday life,” says Iris, “however, when consuming content on a device, such as a laptop, sound consistently comes from a fixed point – the front.”

Ambidio made it by treating our brain as a decoder and creates a continuous sound field with a sense of depth and dimension. It creates an immersive sound experience using only stereo speakers by inserting common cues into audio files that the brain then uses to identify and perceive where different sounds within the audio stream would have come from. Essentially, our brains process the sound the way it does in everyday life.

We look forward for Ambidio to disrupt the entire audio industry.

The ultimate comparison of TP-Link Archer C7 vs C8 vs C9 wireless routers

TP-Link has been well-known for wireless routers with performance comparable or even better than Asus, Linksys, Netgear, etc. with a much cheaper price. More importantly, most of its routers support UniFi and MaxisNet fibre broadband, including the IP phone and IPTV functions.

Let's compare 3 of the TP-Link Archer series of wireless-AC routers at the price range between RM400-RM600: the C7, C8 and C9. Below is the comparison table (click image to enlarge):


The Archer C7 is the oldest among them, with old housing and old web user interface. However, it seems to outperform its successors C8 and C9 in terms of network throughput and maximum simultaneous connections supported, with the help of its 6 antennas (3 internal and 3 external). It has the lowest price too.

The Archer C8 is a new design with new housing and newer, more user friendly web user interface. It also has a dual core CPU. Its USB performance is better than the C7. However, its 3 dual band antennas are shorter, and seems to perform weaker than the C7, despite it comes with Beamforming technology.

The Archer C9 has the same design with C8. It comes with a faster dual core CPU, newer Broadcom chipset, and even better USB performance than C8. However, its network throughput is a bit disappointing in the comparison.

If you are familiar with TP-Link old user interface, here is how its new user interface looks like:



TP-Link is phasing out C8 to replace it with C9, so the availability of C8 in the market is very rare now. However, the C7 is still widely available in the market.

So, there are both pros and cons among them in terms of user interface, specification, performance and price. If you were to choose one of them for your home Internet, which one will you buy?
