is this good enough to power a passthrew

[permafrying]

im looking at a passthrew for my kr808d-1 and i have a car usb adapter my girl gave me just a cheapy from walmart but wondering if its powerful enough to use with the passthrew and not just for charging. its 5v 400mah

I have a 500mah and it will not work with my passthrough. I think you need a 1000mah or more.

1000mHA from HP (for GPS) works but others (I tried a few) with low mHA don't.

Not really. Even if it worked a bit, you wouldn't be getting true 5 volt vaping. 1000mAh or 1 amp minimum but 2000mah, 2 amps would be the best option.

You can get a a 5Volt 1000mah dual car charger at Wal-mart...I use that and just picked one up for a friend. It was a little over 7.00 with tax. I can use all my pass thrus with it. Kr808 and Joy Ego. Or Vapor4 life has the 2000 mah on their website.

aright cool, jus hit walmart once i pick one up im way to impatient to wait on delivery

I'm using V4Ls in my truck, works great. You can also get 2000ma 5v 115v from Walmart on line they work great instead of using your computer.

Does your PT have a battery? If so, that 400 mah just might work, although a 1000 would be better. If you don't have a battery, then a two amp model is your best bet. I use this one from Mad Vapes. You can find them other places but I can verify this one works with a no battery PT and the price isn't bad.

Luckily I have a laptop stand in my work truck so I just plug right in.

i still havent gotten the passthrew i thaught they all had batterys? isnt it bad to plug them into your computer though?

Yes, not a good idea. Could damage the computer and you won't get true 5 volts that way. 5 volt/2 amp USB to AC adapter is what you need.

A passthrough generally has no Battery. However I did just purchase an Ego Usb. It does have a battery and you can use while charging.

The passthroughs are specificity designed to be used on a computer USB port.

(edit) Most well made motherboards or USB controllers will have no issues with a PassThrough. I will not guarantee that it can't damage the computer but I have had no issues with 5 different computers with a KR808D-1 passthrough and the way it vapes I do believe I am getting the full current draw from it. Also we should probably be using mA not mAh.

KR808D-1 passtrough doesn't has battery and delivering an astonishing 5.4-5.7V from USB port on my desktop PC.
I'm using a standard 808 cartomizer (came with kit). VG juice is too thick to use with this kind of voltage.

There were several reports last year from members who killed their PC's by plugging into it with a pass through. Plus I read several posts by computer tech's who advised against it. It makes no sense to do this for the want of a USB to AC adapter.

I do agree that you can cause damage to your computer. That is why I put the no guarantee caveat in. However having said that, I have been building computers for a long time and while I can not recommend using them in good faith, well designed equipment will not have an issue with a passthrough. I guess it becomes one of those "at your own risk" deals.

 

[bstedh]

I will say that I only run the Passthrough and no other equipment off of a singel USB controller. The more devices you have plugged in the greater the current draw on your Motherboard.

As far as a passthrough in a car, I got a usb car charger from V4L and it works fine with my KR808D-1 passthrough. It's great when you have to make those 4-6 drives.

The voltage reading you are getting Is not your true Vapping voltage. You wold have to have your carto or atomizer attached to see what voltage you are getting with a load. You could use a high wattage (10 Watt 2.8 ohm should work) resistor that matches your carto's Ohms ratting to test the voltage however. Also with a little bit of math you can figure out how many watts and amps you are pulling through your Motherboard. I plan on making a stop at Rabbid Snatch (a.k.a Radio Shack) to pick one up to test some of my batteries.

I have to give credit to another thread for reminding me of this even though I should have remembered my self. It's just been a lot of years since I have done any component level work.

(Edit) Gotta love Pluck and Chuck trouble shooting these days.
(Edit II) Please be very careful not to short your leads when testing!
