If you do a lot of public presentation or classroom lecturing, you will find a presentation laser pointer pen as a very useful gadget for you to remotely control the flow of your presentation which run from your laptop and projected on a screen, as well as using its laser pointer to draw the audients' focus onto a particular area in your presentation screen.
I am using the Pisen TS-D192 4-in-1 presentation laser pointer pen and power bank for that purpose. In fact, it is more than just a presenter pen, it is also a 2,500 mAh power bank. It cost around RM70.
The Pisen TS-D192 has 3 buttons and can serve 4 features:
- Laser pointer
- Presentation remote controller
- Video remote controller
- Power bank
When you press its middle button, it will shoot up a red laser beam, with a long shooting range of up to 100 meters.
This Pisen TS-D192 comes with a nano USB receiver, which you can plug into your computer's USB port. It is really plug-and-play and can function immediately in Windows XP and above, even without the need of installing driver.
Its wireless transmission is using 2.4 GHz frequency band, with effective transmission range of about 10 meters. Unlike those infrared presenters that you need to aim the pen to the receiver, this Pisen TS-D192 which use 2.4 GHz wireless technology can work well regardless of its angle and direction, as long as it is within the 10 meters transmission range.
When your computer is running PowerPoint or Adobe PDF Reader, its buttons function like this:
- Press top button to Page Up (go to previous slide)
- Press bottom button to Page Down (go to next slide)
- Long press top button will toggle full screen presentation
- Long press bottom button will toggle a black screen on the display
- The middle button will trigger its laser beam
When your computer is running Windows Movie Player or VLC Media Player, its buttons function like this:
- Double press middle button to toggle between Play and Pause
- Press top button for Forward
- Press bottom button for Reverse
Most of the presenter pens in the market are powered by either AA or AAA size normal battery. This Pisen TS-D192 is powered by an internal rechargeable 18650 Li-ion battery with capacity of 2,500 mAh.
It can be recharged using a normal USB charging cable connecting its micro USB charging port to either your computer or a USB charger. There is a USB charging cable included in its packaging.
It is said that you can use it as a presenter pen for about one year with just a single charge. With its abundant power, it can also serve as your emergency power bank with 5V 1A output to charge up your phone or gadgets.
This is an interesting USP for the product, as you can still making use of it as a power bank when you are not using it for presentation.
