I saw this initially on his YouTube channel, but then I also saw him post his video directly to The Old Place. Asked on his YouTube if he would consider posting to some other alternatives alongside The Old Place like kbin/lemmy and that I was doing light summaries of his videos with links to them on YouTube.
Brief Summary (please watch his video and like and subscribe if you like his content and want to see and hear everything):
— Very surprising, good quality device from PowKiddy. Would be great value from any company but doubly so from them. The new value king!
— Weak chip, but plays as expected (and sometimes better than expected). Most N64, NDS, PSP, and DC are playable, even upscaled!
— Face controls are good. Sticks are of the “better for portability, not as good for playing” switch variety.
— Lots of very clicky/loud buttons, and the split volume buttons are poorly positioned.
— Very smudgy finish.
— Amazing screen for the price. Trounces other similarly priced (and even doubly priced) competitors.
— Has more than expected ports (two usb-c; is safe to use with fast charging, though it will charge at same speed; hdmi out; great quality headphone port; 2 micro sd slots) and features (BT, Wifi)
— Must replace OS immediately due to oopsie from PowKiddy (but it is very easy and supported by the CFW community)
Please go watch another great video from Russ!
Though I’m not a technical expert on these specifications, what you say sounds very similar to what I have also heard.
But, for some reason, I continuously hear that the Miyoo Mini (not the Plus) can be damaged by attempting to use a power adapter with too high voltage. I don’t have one (the original). The Plus also does come with a little flyer that says to never use any power adapter over 5v, even c to c. I’ve never broken that rule, just because I do not want to prove it to myself that they were correct and deal with all of that hassle.
I'm not an electrical engineer so it's probably good to not just trust me and to be careful.
A device would quite likely be damaged if it is given the wrong voltage. However traditionally USB is exclusively 5V. However there are proprietary standards to deliver more than 5V over a USB A-to-C cable and there is the USB PD standard for delivering more than 5V over a C-to-C cable. But to me, it feels very unlikely to accidentally trigger that higher voltage. The device has to explicitly ask the Power Supply to supply that higher voltage and by default only 5V (for the A-to-C case) or 0V (for C-to-C) are supplied.
I could imagine some strange situation where Miyoo put the wrong sort of USB port on the device such that it does ask for a higher voltage. That sound unlikely to me as that would cost more money than not doing it but i guess it's not impossible.
Would be cool if an actual electrical engineer or USB charging expert could test this, but yeah I also wouldn't want to risk breaking my device just to prove that I'm right...
