I find wall outlets useless and inflexible. What is the advantage here, and if the room is used differently, I won't need them anymore.
The same applies to the set of 3 sockets that is about 2.10 meters apart. And you rarely change the bedroom anyway.
USB sockets have no advantage over a USB charger, do they? They usually even charge more slowly, and who knows how long USB will remain standard in this form.
The USB sockets charge with 3 amps, just like a large charger. After all, I need to be able to charge an iPad with them, and that doesn't work with 1.5 amps (normal phone charger). And USB will remain a standard for a very long time; it will just keep being expanded. After all, USB has been on the market for over 20 years now, and even though IT is fast-paced, such things tend to be sluggish.
