I've been following this one for awhile. I finally broke down and bought one. Caught them onsale at best buy for $39.99. I get home, and patiently wait for it to charge.

When It was fully charged, I grabbed my 901 pass-thru, hooked it up, and thought, "meh some improvement, but clearly not something to write home about". I got to thinking well, there might be something wrong with this one. Maybe thats why I have always gotten mediocre smoke out of it. So I grabbed all of my other pass-thrus and did not see any difference.

They all performed the same. Not the greatest thing since sliced bread, but it was an improvement. I was bummed. Well, my co-worker the next day came in and handed me a dead battery and asked me to make him a push button pass-thru. So I grabbed a usb cord off the shelf and went to work. After I got it all together, I hooked it up to my Kensington, took a drag, and started to choke!

Now thats what I want! My lungs filled up, and I was happy! So I though, "Hmmm, I wonder?!". I grabbed my usb pass-thru and sacrificed it to the heat gun. Removed all the guts and direct wired it with a switch in line. BAM! Same improvement!

Bottom line! Remove the crap thats limiting the power and the amperage inside those pre-made usb pass-thrus, add a switch and be prepared for a massive vape!

I am happy now!

doing this and you effectively turn it into a screwdriver.

5.1Volts through a 901 atomizer :)

Good ain't it :)

I have a couple of homemade usb pass thrus. Yep - way good vapor and they burn very hot.
Be careful tho... I put manual buttons on them and if I hold the button down too long (like more than 5-6 secs), my Kensington will drain completely.


not had this problem, regulary hold done for 20 seconds at a time to clean atomizers, burn the crap off

Hi everyone,

I really want to get one of these, but sometimes I can be very challenged and need some help!

I read this:
NOTE:
If you are new to the whole vaping scene and are wondering about power packs and passthrough combinations, please take the time to look around. Ask questions and search for what you want. There are a lot of USB "chargers" out there with circuitry, ratings and uses that just don't work with our devices. The same goes for USB wall socket adapters. If money is an issue, you can easily find affordable, adaptable USB devices that work for under $10. Chances are someone (like me) has already thrown their money away on something that doesn't work.
Don't do that!

So, there are portable power packs that aren't "compatible"? What might they be?

For instance, from the OP I read:

Battery:

Lithium - Polymer Cell. No memory effect. Top off as you please. UL listed with a recycle number on the back of the case.
Output: 5 volt (USB) 1.5 A max.

then, the following for a Kensington Portable Power Pack taken from an ebay listing:


  • Provides up to 120 watts of power
  • Up to 40% smaller and lighter than other power supplies
  • Powers and charges virtually all Cell Phone or Laptop computers from any AC or DC source
  • An ideal replacement or upgrade for your existing power supply
  • Includes multiple tips for use with major brand notebooks
  • Works with most HP, Compaq, Gateway, Toshiba, Sony
  • Over voltage, temperature and short circuit protection
  • Part #: 33197
Specifications:
  • AC wall socket input cable: 6.75"
  • DC auto/air input cable 18"
  • DC power output cable: 10"
  • Input voltage: 100 - 120 / 200 - 240 volt
    - 50/60Hz AC
    - 12 to 16 volts DC
  • Output voltage: 3 to 24-volt DC (configurable)
  • Output current: 6 Amps maximum (configurable)
  • Output power: Up to 120 watts (maximum)

Mmm-kay... what am I reading!? I don't see anything that corresponds to what the OP said.

Can someone please just tell me specifically what it is that I am looking for? All these volts, amps and etc...

Thanks for all your help, and the required patience you must have to muster up for one so ignorant as myself.

Hello ltbv:

Most people just picked this up a few months back when it was on sale for $39.99 Kensington - Portable Power Pack for Select Mobile Devices - Black - K38021 I see now it is $59.99, (most likely because of the demand we created) This Kensington works very well and has great reviews here on ECF in several places. I have 2, 1 for the vaporizer, 1 for the cell phone.

If you are looking for something less expensive, here are the specifications of the Kensington to help in your search:

Battery Chemistry: Lithium-Ion Polymer
Certifications: cULus, CE,FCC
Input: 1.50A Max.
Output: 1.00A Max.
Capacity: 7 Wh (Watt-hours)
Battery Pack Dimensions: 4.0" x 2.2 x 0.37"
Battery Pack Weight: 3.5 oz

Electronics are not my strongest point. But If you find another with the exact chemistry, certifications, input, output, capacity it (should) work. I can only reccomend the Kensington here, as that is what I use.

There are two important numbers to be concerned about for use of an USB external power supply with an e-cig - volts and amps. A properly functioning USB port on a PC will output 5 volts, so you know you want an external power source to put out 5 volts. A USB port on a PC can output up to 500mA (milliamps) of current, but, the heating coils in the e-cig atomizer run much better with more current. Think of what happens when you plug in a iron when you want to press your clothes. Sometimes the lights on the came circuit might momentarily dim under the huge initial rush of household current required to start the heating element of the iron. Vapers have found a current rating of 1000mA or 1 amp to be ideal. So, you would like any external power source that provides power from the USB connetion to be at least 5 volts/ 1-1.5 amps.

All that said, if you have a passthrough with an in-line battery, you will not benefit from the 5 volts of power from the external power pack because the in-line battery is actually heating your atomizer, not the output of the external battery device. In this case, the benefit of the Kensington is the extended amount of vaping you can do before recharging. If you want to experience the full 5 volts, you would need a passthrough without one. The ultimate setup for me is a straight, manual passthrough where I get the full 5v/1A of power/current with no LEDs or circuitry inside the passthrough connector. That is pure, unadulterated power in which I have total control of how long I want to heat my atomizer.

Indeed; I have noticed this, as well. I find it is a good idea to put it on a charge when it has 3 LEDs lit. I rarely see 2 LEDs anymore. I think the load we put on the device with a straight, manual passthrough pretty much taxes it completely at this point. If you are near a PC or AC outlet, you can keep the pack plugged in while using it.
