The "condom" can be designed to be transparent with regard to one or more kind of power negotiation, though this would require a microcontroller, and possibly some analog circuicity for proprietary resistance-based negotiations.
- jessaustin 13y agoThen the condom would be a target for hacking! You've just added another layer to the problem...
- runlevel1 13y agoThat's kind of like arguing that seat belts can cause strangulation. There are always risks, so we just have to choose the less risky option available to us. So between these two... A. The black box charging station I know nothing about. B. The simple device that I brought from home whose single purpose is to limit my exposure to external risk. I'll take the latter. Odds are I'm no worse off than had I plugged directly into the charging station.
- MertsA 13y agoA microcontroller actively doing the current negotiation would be nice (for things like working at the maximum power of both android and apple chargers) but a much simpler and dirt cheap solution would be to hook the data lines up so that they go through a simple filter that filters out everything other than the DC bias so power negotiation would work normally for chargers but no data could cross the cable.
- kbaker 13y agoThere are ICs that do this negotiation already. Like the MAX14636: http://www.maximintegrated.com/datasheet/index.mvp/id/7968 http://www.maximintegrated.com/datasheet/index.mvp/id/7968
