Auto pump on eBay

The only pump I’ve ever tried from ebay was this one http://tinyurl.com/heowcsg

It’s very easy, quick, and inexpensive but it delivered better than 90% of the pumps I’ve tried that didn’t involve water.

If you find that pumping is your favorite PE method, you have to invest in a professional set-up with a pressure gauge. This LeLuv pump is a good starter system: Intimate Body Enhancing Methods for sale | eBay

Thank you everyone for the replies. It’s too bad the width is so big I like the idea of the pump.

I bought this pump on AliExpress.

The exact dimensions of the cylinder are:

63 mm diameter (bottom, where your D goes in)
58 mm diameter (top, where the pump is)
205 mm insertable length.

The silicone sleeve is quite comfortable and replacement sleeves are easy to get and cheap. They don’t wear out quickly though, so haven’t needed any yet.

For me the size is ok: my normal EG is about 15 cm and my pumped length is about 19 cm, so still 15 mm to go. And length does not come easy, pumping.

So is the consensus here that if they made a smaller diameter model it would be a good electric/auto option? I’m looking for hands-free and good suction that doesn’t leak.. Or if it leaks a little, the pump will automatically adjust back to target pressure.

You can buy your own cylinder if you need one with a smaller diameter and/or a longer one. As long as one side has as diameter of 58 mm you connect/insert the pump there. It has a rubber ring to seal itself inside the cylinder.

It does leak a bit, usually, but the pump has a setting [2] that automatically adjusts the pressure to one of the 4 selectable preset levels of -30, -40, -45 and -50 kPa. Not sure how much pressure that is in mm Hg.

With setting [1] it just keeps on pumping, and the pressure goes up (down?) to around -60 kPa, which feels like an awful lot of negative pressure.

It would be nice if the pump were programmable, and able to modulate pressure and such, but I have not seen a pump that can do that yet.
For this pump I think it should not be all that difficult for the manufacturer to enhance its function for that. Maybe even give it a bluetooth interface and have an app to control it.

Hmm.if using my own cylinder.I’ve seen these on Ebay/Amazon as well:

That handheld electric vacuum should be easy to transfer to almost any pump setup. No idea the suction level or how automatic it is.

I think might be that.

I pulled the trigger and bought this:

The pump itself works pretty well actually. However the cylinder is a little too wide, pulls in too much even with the sleeve on. I solved this by cutting (and smoothing) the top off an old cylinder and it slid inside this cylinder and made an air tight seal, with the appropriate diameter for me. The length is also a bit short at about 7.25", but this was also solved when I slid the narrower cylinder inside as it added another 0.5" or so to the length.

There are 4 settings on the pump that range from about 4 inhg up to about 12. The beauty of this pump is that it is fully automatic. If the pressure falls, the pump kicks on and brings it back up to target, hands free. I’ve kept it on for almost an hour and it was flawless.
