I have flagged this answer as very low quality and my flag was rejected.
VLQ's description is:
This answer has severe formatting or content problems. This answer is unlikely to be salvageable through editing, and might need to be removed.
The question is "Can I charge a computer through its USB port?". The answer is composed of few meaningless sentences (something like "buy this thing, it's $20") and a link to a car power inverter on Amazon. It doesn't explain how that inverter is related to the question. It has nothing to do with USB and OP didn't say anything about cars.
That being said, I believe it has a severe content problem and is completely unsalvageable through editing - so it is VLQ according to flag's description.
Was it a mistake or am I missing something?
