RECOMMENDATION:These are a ‘BUY’, but it can be a little confusing and disconcerting because they work by scrambling the data connection, so that the connected unit cannot be discerned and thus you cannot transfer data to/from it. That means that a remote system can see that something is connected, but cannot determine what.THE GOOD:1. Works and looks good, especially with black cables2. Lightweight so you can just leave it connected to cables that you want to use for chargingTHE BAD:1. Note the info under Recommendation above. It works, but can be concerning if you connect to say a windows laptop, because the laptop will see it. The laptop won’t be able to figure out what it is and thus not install a driver, so your data is safe but in a little bit of a disconcerting way…

Overall; Pricey but sturdy metal.Works as advertised. I didn’t notice any slowing of charging speeds. Could be a little on the pricey side compared to what else you’ll find here but these are actually made of pretty sturdy metal so I’m not worried about accidentally crushing one at all. Tested it with my phone to my computer and couldn’t get the computer to recognize anything so it’s doing what it’s supposed to.

when connected to the PC it is not detected so it looks like it really cuts off data transmission and leaves only the charge, but the charge of energy is extremely slow. For example, if I connect my original 65W charger, the smartphone charges to 100% in 30 minutes, but if I use this adapter, charging takes about 6 hours, which is a very long time. I also tried charging in a public place, and if I turn on the game, the phone discharges faster than it charges. That is, this adapter can only be used for charging but not use the phone at the same time. You should have such an adapter just in case, but in most cases you are unlikely to use it.
