USB Passthrough with Battery

[Harrygrowth]

I have a USB PT (510) with battery box. Did I read somewhere on this forum that removing the battery from box and soldering a wire between the neg and pos bat contacts in the box, I would have a 5v passthrough? I do have a 2amp output USB wall adapter/charger.

not sure about the voltage, but some USB's are 5V. It would make sense to me if there is no restriction in the circuitry that you may be ableto get hat amont out of it. I'm trying to do the exact same thing so I have a back up for when things croak, and if I make any leeway I'll make sure to tell ya. These things are so simple, and I've been racking my brain for hours! My othr brand I was on forever I had no trouble wit. These 510 passthroughs are a bit different as far as set up and grounding. Hmmm.... I'll let you know if I come up with anything when I'm digging through here. Best of luck man!

There's circuity in that PT, for charging and for vaping. It is expecting a 3.7 volt Li Ion battery.

Making a 5 volt PT is easy... search this sub-forum a bit. 3.0 amp button, atty connector, USB cable, housing. If you're soldering wires anyway, do it the proper way. Oh, and get a 2.0 amp wall wart/usb hub/charger if you don't already have one.

Thanks for the response. I did try making a PT but no luck yet. I'm just not getting much juice to the connector. Not sure if the switch is bad (MV horn style). I can here it faintly fire but getting nothing to speak of. The wires on the USB cord from MV are sure thin. Perhaps my wiring is wrong or it's correct but using wrong ones. I'm using the red and black. I should check the output with multimeter and see where it's at. BTW i am using the 2 amp charger.

Ideas:

1) Use a thicker USB cable... sometimes the real thin ones have too much resistance.
2) Yeah, the button is not making good contact
3) Hollow solder joint somewhere.

Yes, use the meter. It won't tell you how it's doing under load unless you have some resistance. Some make a homemade special testing connector for this purpose.
