    Quite a few of newer phones, including my Samsung, have the ability to charge wireless through some electrical gobbledygook. This together with the ability to transfer files via wireless, or email, can make the USB port redundant. But I don't think this wireless charging ability comes with 'inexpensive' phones.

    If you want a dielectric grease that does a bunch of other things and is relatively inexpensive, try Super Lube.  I started using it years ago after reading a tech piece where they used it on winch pawls, where you would normally use oil because conventional grease can dry on the pawls and lead to disaster.  Anyway, it is dielectric, food grade, and can be used on pretty much any marine thingy that needs grease.  I keep one grease gun loaded with it on the boat and find it works for just about everything including coating battery terminals and other dielectric needs.

    Just another thought,

    Before moving to my first iphone (5) with the new power connector I used blackberries. Having a dedicated, secure dock or place to charge your phone goes a long way to avoiding problems with your microusb ports as they tend to be a bit fragile.

    I also always stuck some Prestik over my charging and earphone ports to prevent dirt and water incursion. 

    But again, I'm the guy who bolts the family laptop to the table believing that a laptop is a portable computer and not a computer to be operated on a lap.

    So take my opinions from whence it came.

    Hi,


    I am out of the country at the moment so can't tell you what I use. I have a big tube I got from my old man and he's off on a 3month yacht delivery right now so can't ask him either.

    Works a treat though, I have some very cheap non marine USB ports still working perfectly and corrosion free on my boat after a number of years.

    Magnetic charging cables might be a solution for those wishing to avoid corrosion on their phones/tablets charging ports.  I've used them, mostly successfully, on my sons phones in order to avoid damage to the charging ports from the cords being pulled in inappropriate directions.  There is a small stub that stays permanently in the charging port and the special charging cord that magnetically attaches itself to this nub along with some small pins.  They seem to last about 6 months to a year before they start to become erratic for a reason I've been unable to diagnose.  I've only used the cheapies off e-bay, so maybe that is part of the problem.  If you fill the charge port with dielectric grease before you plug the tiny stub into the phone I would expect the port to last a very long time.  It's easy to revert back to a regular charge cord should things not work out.

    Although tiny, the magnets in the cord are strong enough to effect our binnacle compass if the charge cord is closer than 4" (10cm) from the compass and in line with the compass card.  Something to think about if you have a tablet mounted on a binnacle and are charging it, or some other situation with a device close to a compass.

    Thanks everyone.

    My iphone was 8 year old, so I guess it has had its time.  It still works when plugged into a power source, so perhaps replacing the battery or a iTunes reboot would get it going.  That said I would like something newer with a larger screen.

    Would accept splashproof, full waterproof is probably to much ££s.  Would use a case when at sea. For now it will be mainly used for hill running / ski touring and a case is a hassle.

    Here's a good write-up of the use of grease in electrical connections.

    According to the writer, dielectric silicone comes out best.

    "In regular low voltage multiple-pin circuit connectors, such as automotive applications, flooding with a proper insulating grease of low-viscosity dielectric grease is perfectly acceptable unless a manufacturer recommends against it. The grease should have good stability and not contain metals in any form, and be specifically designed for use as a dielectric grease. This generally is a silicone dielectric grease, although some Teflon based greases are acceptable."

    Can you recommend a brand, Nicolaas? I'm aware of silicon greases with thermal conductivity, but not electrical conductivity. That would be a useful thing to have aboard.

    I'm not convinced you actually want an electrically conductive lubricant in your microUSB connector... 

    I have heard good things said of Contralube 770, which is sold as an electrical contact grease. Not cheap!

    I was wondering about that.

    Is this the kind of thing we should use?
