Isn't this just a lesson to always read the output values on adapters?
- hddherman 3y agoHi, author here. If the writing on those adapters was easily readable by the visually impaired and surrounded by bright red/orange colors, this wouldn't be that much of an issue. I had one hell of a time trying to even photograph the output voltage etching specified on the adapter itself.
- dncornholio 3y agoThe info is still there.. You were not being lied to.
- iamflimflam1 3y agoWell, USB is a standard - you would expect a standard USB output to deliver a standard voltage.
- itslennysfault 3y agoInterestingly, even Samsung phone chargers put out 9v, but I think they only do that when connected to a Samsung device. On the plug is says 5v and 9v, and (I'm assuming) they switch to 9v when they detect a device that can use it for fast charging.
- ComputerGuru 3y agoIt’s called QuickCharge and was a standardized version of Apple’s fast charging or USB C PD many years before USB C was a thing. Samsung was a key player. The charger emits 5V unless the device supports higher voltage and negotiates it.
- samus 3y agoIt's a USB port. Differently than the dozens of proprietary charging connectors that were ubiquitous before micro-USB and USB-C dominated, consumers have an expectation that it adheres to the specification. To be on the safe side, one would actually have to check the voltage. Both the output voltage and whether these are really 0V and 5V to ground. The output frequency spectrum should also be checked.
- dncornholio 3y agoTo be honest, we used to have those round connecters that would vary in voltage a lot more, so I always check the adapters sticker.
