So, I was at TRU earlier, looking at their clearance aisle. I found this set of car accessories for a shitty kid's tablet, it was priced at $50 but it was on super-low clearance so I was able to get it for like $1.50 I bought it because it had a USB car charger in it, and I needed one of those, plus it had an LCD cleaning cloth, headphone splitter and some other shit.
One of the things inside was a USB power cable for the tablet it was made for. I was about to set it aside when I realized that it looked familiar. It's got the same connector as a power adapter for a Gameboy pocket. And it worked! I can power my Gameboy Pocket over USB!
Is this safe to do? I see on the back of the GB that it is rated at DC3V 0.7W, while on the cable I see printed 300V. Is it really carrying 300V, or does it mean 3.00V?
