Silicon Grease
« on: January 05, 2019, 11:17:17 am »
Is there any reason why not to put silicon grease in a mini / micro usb port? (I'm wanting to do it to add some protection while charging in the wet. Edges and other electrical stuff.) Thanks.

Main argument against would be that it would encourage the accumulation of dirt, but I don't think that's anything a squirt of IPA wouldn't solve.

I don't do it myself, simply because I don't use USB connectors in wet environments.

er... cos there's no need to?
Seems like far too much effort to go to to avoid having an etrex  ::-)

+1 for etrexs.  But the silicon grease has solved my intermittent connection problem on a micro usb port. (I think these things corrode fast when they get a bit of water in them.)

Yep, DC voltages on small connectors in the wet is a recipe for corrosion.  It'll be far worse than, say, dynamo wiring.

Most USB connectors aren't sealed at the back, so as long as you're happy with grease being pushed inside of the device each time you connect something...

The mini-B connectors used by Garmin are the exception here.  Indeed, I suspect the reason they've stuck with them for so long while the rest of the world was standardising on micro is because they've got a design that's waterproof.
