Really Not feel'n the joy with the RCR123A

[Casey@PS]

Just trying to figure how an attomizer can make a power pack shut off.

The atomizer can short the entire unit and shut down the PT and the power pack. It's weird, but it does happen- usually when there's no silicone gasket.

You need to be careful about not mixing 3.0V batts vs 3.7V batts with the wrong chargers. I don't know all the specifics, but get them before you buy. Also using 3.7V RCR123As gets you over 5V even with the resistor if I remember correctly.

Hopefully if the power pack is shut down it is undamaged?

I have yet to hear of one being permanently damaged.

The janty kissbox titanium atty shuts down my Kensington every time.
The kensington will simply turn off.
Then i have to replug into the wall socket to get the kensington working again.

I do not know why one sort of Janty atty does this.

This atty reads 0.22 ohms

All my other atty's are in the 0.3 ~ 0.35 ohm range

I suspect you mean more like this -

Hot Probe (Red) to the center hole of the atomizer (flipped upside down) And put the Grounding Probe to the threads ... = You should get your readings!!!

Brian, were those old atty's from me? I ask, because those are RN4072 atty's, not 801 atty's ... I tested a handful of new 801 atty's and never saw over 3.5 ... Most were in the 3.2-3.3 ohms range ...

I tested a series of 5 different kinds... Here were my results:
4072 Average - 3.7 ohms
801 Average - 3.3 ohms
901 Average - 3.1 ohms
510 Average - 2.9 ohms
401 Average - 2.5 ohms

multiply your readings by ten. the setting on the multimeter should be "x10", which means you multiply your result by ten to get the correct result.

Ah !!
I have learnt something.
Thanks

 

[quovadis]

Could someone please show me how to measure a USB?
What do i set the multimeter to?
Where do i place the prongs?
I can't get a reading.

thanks

Just trying to figure how an attomizer can make a power pack shut off.

Trust me it does. Mine is doing the same thing with my kensington. I have 1 that doesnt and 2 that trips the protection. All 3 work fine when hooked to my computer.

I have found out that the atty's that measure under 3 ohms, shut off the kensington.

I have no clue why less ohms would shut it off.

 

[gjrhine]

less ohms = less resistance to power,

The reason that it would shut off when there is less resistance in the atty is because the lower the resistance the higher the current draw. so at around 2 ohms resistance at 5 volts the Atty would be trying to draw 2.5 amps of current.

The outer pins on either side are your power and ground wires, when looking at the female socket of a USB port and the white block at the top the left most pin is the positive 5 volts source and the right most pin is the ground source.

Thanks a lot.
