Pumping surprise with usb heat pads

I got my pump at the end of April and have explored it a lot. I first tried to diy it wit h3d printing, but gave up because of sharp edges and lack of the actual pump.

I’ve been pumping on and off, and at first to just see what happens. I was never self conscious about my size, but the what it would do

Then I noticed I actually gained length, which was not what I expected. It also did not go away after a week or 2. Now after 6 months I have gained about 2cm by just pumping. Now I have added usb heatpads since I read that heat does wonders and I had them around anyway. It really speeds up the process, making me able to use less pressure. I just put the pads around the pump and hold them there with an old sock cut into a tube.

While I do recommend the usb heat pads (I have one that has 4 pads) I have no measurements and so far have just used max setting to get to temp and mid temp for longer sessions. I didn’t like high pressure, since it has given me red spots on my tip, which now are slowly going away.

I will keep it up for now. It seems to work and it’s just funny to me that it works. I am now 20cm BPEL when barely erect with 16cm circumference (not after pumping).

I hope this is useful fir anyone, I am just giggling about the results.

What usb heating pad are you using? If you don’t mind sharing.

Here’s a link to similar pads, but 5 instead of the 4 I have.
I don’t think it’s a good idea to get one with 5 pads as the one I have already pulls 1.5 amps (7-8 watt) and with 2 you’d be golden if you isolate the outside a bit. I sometimes just put a blanket on my lap, but I worry about the whole crotch area getting too warm.

Excellent idea using the sock! I’ve tried using rubber bands, which probably didn’t work nearly as well.

You probably don’t don’t have to worry about getting hot enough to damage. For most people the level of maximum discomfort is well below what it takes for that. A cooking thermometer slid down between the pad and the tube is useful for a more accurate check, though.

**UPDATE**

While it still works like a treat, I did have a potentially big problem with the heat-pads.

The pads are connected to the usb port using bare conductive thread. The way I layered the pads to make them fit my pump worked fine, until it didn’t.

2 of the pads made contact, shorting, and generating a lot of heat in one spot. I knew the smell of burning plastic, so I caught it before it broke anything.
Now I covered the side of the bare wire with some tape and it hasn’t destroyed itself as of yet.
I just want to make you all aware that diy fabricating is fine, but you need to know the sketch in the project.
