KR808D1 USB Passthrough

[scurry64]

I was considering ordering a KR808D1 USB Passthrough to use while I'm at work.
It seems like a great way to vape during the day and not have to worry about batter life.
My concern is with safety.
Has anyone suffered any damage to their computer from a passthrough?
Is it perfectly safe?
Thanks for your input.

I have heard many times that damage is possible. I have seen one actual post by a member who fried his laptop. I would find another place to plug in if i were you.

 

[AmandaMarie]

I am also in need of a passthrough and have read about the possible damage. I plan to use my pt running straight off of my wall charger

 

[BulletTooth]

Yeah, I use a wall/power strip. Don't even risk damage to a computer.

 

[Loveridden]

I have heard that it can damage the motherboard or something like that so I just plug it into a usb wall charger

 

[kittypie]

V4L has a USB wall adapter that works perfectly with my PT. (808 PT is my favorite way to vape)

some say yes, some say no re using a PT directly from the computer. Some say it depends on the age/quality of the computer. I'd get the USB wall adapter to be on the safe side.

why is it that all the chargers i see available have a USB plug rather than the standard outlet plug? hardly ever do i think to myself...i wish i could charge this through my computer. its a nice option (not after reading this thread though), but the plug should be standard, with a usb converter as a secondary option rather than the other way around.

Kemosabe sir charging on your computer via a usb adapter shouldn't be an issue. The most I've seen any charger pull is 400ma, usb 2.0 ports are designed to run at the very least 500ma, usb 3.0 900mah. There are ones that run higher, but that's the standard. Problem is to run the pt at 5v using a 3.3ohm carto you'll need at least 1.51amps (more for lower ohms). Very few computer's usb ports are deigned to run at that current, and even if they are you're putting strain on the 5v line of your psu if it doesn't have enough amps for all the items on the line. Wall adapter is the safer choice.

Moved to correct sub forum.

if your worried about your laptop you could always use a USB hub correct?

I've never had a problem using our USB passthroughs on a Windows Laptop or an iMac. Never had a problem using the USB charger either.
Were the problems mentioned here created by mixing and matching incompatible batteries, pasthroughs, chargers that aren't compatible?

 

[Morandir835]

John K sir the problems come from what voltage the pt runs at, what ohm carto, and maximum output of your usb port and amps on the 5v line of your psu. A 2.2ohm carto on a 5v pt requires 2.27a of power. A standard usb 2.0 port is rated for 500ma (.5a). There are ones that provide more amperage, but that's usually 1-1.5a. Very few provide 2.0a of power or above. Add this to the number of available amps on the 5v line. Your chipset, ram, list goes on all use it. Once you've reached your amp limit you start to stress the psu. Add all this together and using the pt on the computer just doesn't make sense.

 

[John K]

I'm sorry, I misunderstood the question. I thought they were asking about standard KR808D-1 Passthroughs. I don't mod or mix-n-match the equipment. Never had a problem using the standard KR808D-1 parts.

 

[Morandir835]

John K sir standard kr808 pt's are 5v, it's the newer ones for use with horizontal coils that are 3.6v.

I was actually thinking that a passthrough was going to be my next purchase. So do you think the 3.6 volt kind from bloog or volt is the way to go and WONT harm my computer ? Or are you saying any shouldnt be used on a computer. Would you recommend a 2.0 wall adapter ? I know the wall adapter with the V2 is only 1.0 but volt makes a 1.5 , so would this be ok?
or would YOU recommend just getting a USB Powered HUB like the Belkin that has 4 USB Openings?

 

[Morandir835]

Don't reccomend using any pt off the computer save for those that are a battery/pt (like the 808 ego). They run off the batt, not the 5v line of your computer Jys1fan (sir or Ms.?). Wall adapters are cheap to replace, mobo's and psu's aren't.

That would be the ideal way to do it.

Thank you kind sir. I too am a sir. 1 other thing, the volt pt has a 1.5 wall adaptor but most others I have seen recommend a 2.0 wall adaptor. Is the volt 1.5 good enough? Also, if I go the Usb route, do I have to make sure those put out a certain amount of power too?
And finally, I saw the discussion on 1st gen v2 batts and not to use them on a 2nd gen charger but its ok to use the 2nd gen batts on a 1st gen v2 charger? I am confused a little since the wall charger is 2 parts. You 1st screw in the batt to the usb part and then the usb end goes in the charger. So should 1 not charge any batt of a usb hub or what's the situation there concerning both gen batts. Because if I don't get a pt, I will need another batt and probably go with the volt or bloog. Again I thank you.

 

[Morandir835]

The usb chargers are a much different situation Jays1fan sir. Gen 1 usb chargers are rated for .2a, gen 2 .15a. That's well below usb 2.0 .5a standard limit. The wall adapter by volt is rated for 1.5a because they expect to use their pt rated for 3.6v (3.55-3.71v actual) on it. If you're using say a 2.8ohm horizontal coil on it and your's is at the highest seen of 3.71v, you're still only pulling 1.325a. You are correct, you can charge gen 2 batts on gen 1 chargers, just not vice versa. If you're going with a hub, suggest getting a powered hub. Hubs will split the power among the ports. So if you get a 2000ma hub, that means it can give up to 2a of power comined between all the ports on there. So in other words if all 8 ports are filled, each will only get .25a of current. Don't suggest using these for pt's either, they usually have one or two ports that will output 1a, but only if no other port is in use. 1a isn't enough for a pt either. Hope this helps.

morandir835 sit , yes VERY helpful and I thank you for your time. Only one thing I am still unclear on.
is it the charger that plugs into the wall OR the usb Cord that the ecig plus into that makes the going from a gen1 batt to a gen2 charger NOT Work ? I would think it would be only the cord since many companies give you a usb charger connection cord with some kits and not the wall adaptor itself.
thanks again.
