The Infiniter Quad XP4 is a multi tool containg a red laser pointer, a white LED flashlight (torch), a ballpoint pen, and a PDA stylus.

It comes in a brushed aluminum, pen-style case, and the laser pointer & LED flashlight are powered by three LR44 button cells contained inside the pen-style case.

The emitted wavelength of the laser appears to be 655-665nm, in the red portion of the spectrum.

SIZE

You'll need to feed your Infiniter Quad XP4 the included batteries first (see below), then you'll be ready to rock.

The Infiniter Quad XP4 has four modes of operation:

1: Press and hold down the topmost button to turn the white LED flashlight on. Release the button to turn the flashlight off.

2: Press and hold down the second button to turn the red laser pointer on. Release the button to turn the laser pointer off.

3: Hold the unit near the center and turn the pen end counterclockwise (as if loosening it) to extend the ballpoint pen.

4: Hold the unit near the center and turn the pen end clockwise (as if tightening it) to extend the PDA stylus.

The Infiniter Quad XP4 comes with a spring metal pocket clip, so you can carry it around with you wherever you need it.

The Infiniter Quad XP4 uses three LR44 button cells for power. To change them, grasp and hold the unit at the clip; orienting it so the LED and laser face the floor, unscrew the pen-end (the end with the ballpoint pen and PDA stylus) and remove it. Set it aside.

Tip the used LR44 cells out of the barrel and into your hand, and dispose of or recycle them as you see fit.

Stack three new LR44 button cells on top of one another, button-end (-) negative facing up on a flat surface like a table or a counter. Lower the barrel of the Infiniter Quad XP4 over them, slide it to the edge of the table or counter, and place your finger over the open end while you're sliding it off the edge so all those batteries don't just clatter to the floor.
Invert (flip over) the Infiniter Quad XP4 so the open end faces up. Remove your finger.
Pick up the pen-end, and screw it back on over the open end of the Infiniter Quad XP4.
There, done.

It sounds harder to do in print than it actually is to do it.

Current usage measures 83mA for the LED, and 33mA for the laser diode.
I used my DMM's 2A scale for these measurements.

This product has a laser pointer in it. So I won't whack it against a steel rod, run over it, try to drown it in the loo ("toilet", "toilet stool", "john", "can", or "commode" for US viewers), throw it, stomp on it, or subject it to other abuses that a flashlight might have to endure. So this section of the web page will be more bare than this section of the page on a page about a flashlight.

You can use both the laser pointer and the flashlight together; however some of the flashlight brightness will be lost when you do this.

The laser pointer portion of the Infiniter Quad XP4 is CDRH Class II, making it legal for European and UK users to use.

I haven't used a CDRH Class II laser since the early 1980s, so I really wasn't prepared for the intensity level of this unit. It's still plenty bright enough to use for presentations in most locations, but not as bright as most laser pointers sold in the United States.

The ballpoint pen writes in blue ink, and the writing quality is about on par with Bic disposable pens sold in the United States.

I do not own a Palm Pilot or other PDA, so I cannot test the PDA stylus in the manner in which it was intended to be used.

TEST NOTES:
Sample of the Infiniter Quad XP4 was provided by Paul of Bluesky Marketing, and was received on 09-16-04.

VERY, VERY IMPORTANT: Paul was given explicit written permission to use in any manner he sees fit any of the photographs on this and other web pages on this website that contain his products. So please do not be alarmed if you see any of my photographs on any of his websites.
