My CyberPower UT800EG 800VA/400W UPS with built-in AVR

It is really value or money to use RM128 to get a branded Uninterrupted Power Supply (UPS) system with capacity of 800VA/400W to provide power protection for my desktop computer and Internet connection devices.

This CyberPower UT800EG UPS has a very compact size, about the same with a typical  2-bay network attached storage (NAS) system.

It is very easy to operate, with only one on/off button. It uses 3 LEDs and a beeping buzzer to show its status and condition.


Selling at this kind of cheap price, it is within my expectation that it only has basic UPS function that generates simulated sine wave (instead of pure sine wave), and basic Single Boost, Single Buck type of Automatic Voltage Regulation (AVR) function. It has electromagnetic interference (EMI) filter and radio frequency interference (RFI) filter.

It uses internal current limiting  and a fuse for overload protection. It has a relatively low surge suppression rating of 125 Joules.

Beside its cheap price and compact size, another thing I like is its 3 universal type power outlets. With this kind of power outlet, I can directly plug in my equipment within the need to use special kind of IEC-320 power cord.


Another thing I like is its patented energy saving feature called GreenPower UPS Bypass Technology, which is claimed to be able to save substantial amount of power consumption.


When use with normal desktop computer and 27 inches LCD monitor, it is able to provide slightly more than 10 minutes of power outage protection.

This UPS comes with 2 years warranty, which registration can be made online.

My HuntKey SZL307 3 gang universal socket power extension with USB power output and surge protection

I just bought this HuntKey SZL307 3 gang power extension for about RM50. It has all the features I wanted, namely:

  • Long and thick power cord (2 meter)
  • Universal power sockets
  • USB fast charging ports
  • Independent on/off switch for each socket
  • Surge protection against overload, voltage fluctuations, surges and spikes
  • SIRIM approved

This HuntKey SZL307 power extension comes with 2 USB charging port with fast charging output of 5V/2.4A, handy for charging mobile devices without the need of their power adapter.

Its surge protected sockets are universal type, can fit in various types of 3-pin plug and also 2-pin plug.


Unlike its competitor Belkin SurgeMaster which only has one on/off switch for all the sockets, this HuntKey SZL307 has individual on/off switch for each of its 3 power sockets, and there is LED indicator light for each of the switches.

It comes with 3 years warranty. Most importantly, it is SIRIM approved with a SIRIM sticker on it.


There are other variants to this product, such as the HuntKey SZL407 which has 4 gangs and selling at a more expensive price.

Using handphone to pay Selangor & KL street parking and parking compound with Smart Selangor Parking mobile app

The traditional ways of paying street parking to municipal council is no doubt inconvenient, be it using the parking meter or parking coupon.

Using parking meter means you need to get ready some shillings, park your car, find and walk to the parking meter, feed the parking meter, print out the receipt, walk back to your car and display the receipt on your car's dashboard.

If you need extra time, you have to wait until the parking period on the receipt is about to expire, then rush to the parking meter, feed it and print out another receipt to be displayed on your car's dashboard.

Using parking coupon means you need to buy the coupon from its sales agent, estimate your parking time, scratch the parking coupon(s) after you parked your car, and display the coupon(s) on your car's dashboard.

If you need extra time, you have to walk back to your car, scratch additional coupon(s) and display them on your car's dashboard.

With the initiative from Smart Selangor Delivery Unit (SSDU), now you can pay for street parking in Selangor state as well as in Kuala Lumpur area by using their Smart Selangor Parking mobile app, available for download in Google Play Store and Apple App Store.

In addition, you can also pay for parking summon compound in Selangor state and Kuala Lumpur area using the same mobile app.


Although the user interface of this Smart Selangor Parking app is quite ugly looking, it is indeed a very handy app for you to pay street parking and parking compound in Selangor and Kuala Lumpur. You can use it to monitor the remaining time before your parking period expire, and use it to extend your parking period with ease too!

This app supports payment to multiple councils in Selangor and Kuala Lumpur, and it is able to detect your location and automatically decide which council you should pay your parking to.

The supported councils are:

  • Majlis Perbandaran Ampang Jaya (MPAJ)
  • Majlis Perbandaran Kajang (MPKJ)
  • Majlis Perbandaran Klang (MPK, newly added recently)
  • Majlis Bandaraya Petaling Jaya (MBPJ)
  • Majlis Daerah Kuala Selangor (MDKS)
  • Majlis Perbandaran Selayang (MPS)
  • Majlis Perbandaran Sepang (MPSepang)
  • Majlis Bandaraya Shah Alam (MBSA)
  • Majlis Perbandaran Subang Jaya (MPSJ)
  • Dewan Bandaraya Kuala Lumpur (DBKL)


Before using the app to make payment, you need to reload it in a similar way you reload other e-wallets in your phone. Note that the money you loaded into the Smart Selangor Parking app cannot be withdrawn at this moment, so it is not recommended to load too much money into it.

Then you need to register your car number plate in the app. You can in fact register up to 10 number plates under one user account in this app, and select which car number plate to pay for the parking when you use it to make parking payment.

Despite there are still many rooms for improvement in this app, I still strongly recommend it to car owners in Klang Valley area, as it is really very convenient to pay for the parking.
