My comments on this standard
This will hopefully eliminate the clutter of mobile phone chargers that exist in most households and the worry concerning lost mobile phone chargers leading to mobile-phone downtime.
The standard can also allow a self-powered USB hub to be re-purposed as a “charging bar”, which would be a boon to the food, beverage and hospitality industry as well as householders. I had heard mention during ABC 774 Melbourne’s coverage of the Victorian bushfire crisis of a pub which was being used as a relief centre having its tables covered with phone chargers. This setup, like most homes and offices, would have one or more powerboards with three or four chargers plugged in to each powerboard. The different chargers would only be able to fit particular phones. A self-powered USB hub working as a charging bar would be able to service 4-7 phones from one power outlet. That would be enough to cover all the phones used by people sitting or standing around an average dining or bar table used in most cafes, bars and similar places. Larger tables like picnic benches, banquet tables or standard tables pushed together can be catered for with a few 4-7 port hubs powered from one standard powerboard.
This also leads to a smaller physical footprint for charging multiple phones and less need for powerboards for this purpose.
Another problem this will also solve is the common problem caused by two or more “wall-warts” plugged in to a double power outlet or powerboard. Here, you have the “wall-warts” not being able to be close together without one of them falling out or making poor contact with the AC supply, thus leading to erratic operation or damage to the charger, mobile phone or AC supply.
Once this interface standard is implemented on mobile phones, this can encourage other personal-electronics manufacturers to use the same connection for powering or charging devices like VoIP phones, MP3 players or digital cameras.
Another improvement would be to simply design innovative power supply concepts without having to factor in different voltages or plug types in their design. Examples of this could include pocket solar panels for personal-electronics devices or powerboards that have built-in USB hubs for low-voltage power supply to gadgets.
Yet another benefit would be that the same socket on the one device can perform two different functions – power supply and data transfer. This is a bonus not just for end-users but for people designing these devices, because devices like mobile phones have fewer holes to be catered for in their design. In fact, an MP3 player or mobile phone could just have a standard “headset” jack for analogue audio sent to and from headsets and a micro-USB socket for external power and data transfer.
The only company whom I think will keep away from the standard or postpone its implementation would be Apple. This is similar to how they treated UPnP and DLNA standards – if it wasn’t created by them, they are not in a hurry to implement it.
Look forward to fewer chargers and adaptors filling our drawers or cluttering our powerboards!
