Diy Passthrough Problem

[highcountryvapor]

I just made a passthrough that I thought was going to be 5 volts but it feels closer to 3.7. The usb cord I used was off an old mouse for a computer with the markings (DC 5V 50mmA). Do I need a bigger cord?

what gauge is the wire if its not thick enough you wont get all the power. if your powering it off a ipod charger they dont seem to be enought power. also plug it in and check voltage.but i think the wire ssize is culprit. same principle as wiring a car amp. thicker wires for higher watts.

What are you using for power? If you're using a USB wall adapter, you need one that's 2amp. Many are only 0.5amp (500 mah) and that's not enough to power it.

I pluged it in to my computer for power. I'm not sure what gauge the wire is but I have a larger wire that I am going to try. It works great for 3.? volts

14 is pretty big lower the number the thicker the wire. I honestly recomend at least 18 awg 14 is thicker but most of the usb i see have around 22 or thinner. the one i have runs 18 awg and is flawless. whats the rating on your switch as well.

There is no switch I converted a Copper Hex so I just made a fake battery and ran the cords to pos and neg

copper hex? auto batt? if so that might be the problem

[highcountryvapor]

No it not an auto battery it just has a post that drops down and connect with the battery directly. So I put a larger gauge wire on it and it is not 5 volt but we are getting closer. It might just be my computer at this point but I am happy with it for now. Thanks for the help.

it possible your copper hex head is killing it. gotta remember resistance as well.

this is a decent switch. well at least from radio shack.

Most computer usb's are only 4.2v. Just sayin'

[highcountryvapor]

That sound about what I am getting out of it. For sure more than 3.7 but it's not 5 volts. I think I am going to get a 2amp usb plug and see how that works.

I doubt the wire is the problem,as the wire in factory ecig batteries is very light and they vape .I would be inclined to think there is a short somewhere or a not so good connection.A volt meter would be a good thing to have for times like this.I would be wary of hooking that to my puter if it is not working right .A switch is a must though.
