30 Pcs Silicone USB Cap Port Cover Anti Dust Protector for Female End Black

Good product for the price that does what it's sold to do, go into USB-A ports and cover the opening. I don't know about "water resistance" for this thing but I would not trust it with submerging any product with this thing into water and expecting the cover to block out water. I bought this thing to block out dust and it does so very good. However yea that seal strength wont' keep out water.Don't push it in too far. If you do It will become very hard to take out. That little nub on the top of the product helps juuuuuuussssssst a little bit but don't rely on it too much or else it'll break off. You're better off just pushing the product in 50-80% the way into a USB port so that way a least a little bit will stick out and will make it easy to remove. Works like a charm for me.

This is one of those things that is so simple it is either five stars or it's zero. I have an almost OCD-like tendency to bring order and organization to everything in my house and these USB port covers have been like the pure cocaine to that addiction of perfection. My unused ports on my gaming consoles, laptops, desktops and other devices are now neatly covered and protected from dust (I cant attest to moisture as that is a testing scenario I'm not willing to put my devices on the line for). They sit snugly, are flush and unobtrusive. The "USB" letters stamped in the rubbery material are a nice touch to let you know what's behind the cover. They are easy enough to remove with just my nails, a knife, bobby pin, tweezers or anything sharp. I cant say I have ever needed USB port covers but I do have an old 16 port USB docking station where the USB ports sit vertically and are old enough that the amount of dust they are collecting, though not catastrophic, is disturbing to the conscience and worrying mind. These covers, while perhaps not absolutely necessary in most cases, offer peace of mind.I am thoroughly satisfied and I wish all devices came with these natively.

Got a water proof power outlet with USB ports for my patio table. It is exposed to the elements. Saw the USB metal pads had a little rust. Put the plugs on to keep out anymore water. Think they will work well. Snug fit, but easy to remove.

Does the job. Plugs USB A slots. A bit more difficult to remove from the ports than I'd like. Picked these up to plug ports I don't use very often (in-car) so they do the job. Could be better, but it's a simple product so can't complain too much.

These work perfectly for all of my Solar generators and UPS battery system boxes that have USB A type sockets that I don’t ever use. I mainly plug into the AC plugs so the USB A spots would only get dirty or dusty depending on if there in the garage or in the house. They also perfectly fit into the 30A TTS-30 diagonal flat socket holes to protect them also. All in all I really like them and recommend them.

Don't know why water resistance is even there for a rating.. these plugs are not water resistant at all but what they do keep out is the dust and lint balls that came make for a bad day.Ever have to wiggle your cord around? Well usually the first time is because of a dirty connection.. the more you wiggle the more your chances of breaking the port can happen.They do make the cords a lot stronger than the ports now because we are always bending them and while it's good for the $5 cord it's bad for your several hundred dollar phone or device.When not in use cover them ports!

There's some wiggle room so they might fall out in the right situations. Alternatively, if you have something with a recessed usb port, you'll need tweezers or something to get it out. Big plus is how many there are for the price, would recomend.

These things work just as the are intended to.
