I have found this one to be the best available and at a really good price. It's easy to use, and it has not failed me to date.
The best feature is the reversible polarity. In a rush or pinch you may grab an adapter with the wrong polarity by accident. Sure, it'll work, but you could definitely end up ruining your adapter and or the device you are powering up.

Hey, soo do the signs on the power adapter and the thing u wanna power have to match?
Hi, if you mean the + - (plus and minus) yes, that's the polarity. Often times I was able to find the right voltage and amperage, but the polarity was always wrong. This is selectable, so it's awesome. I hope that helps.
@@meditationsleepsounds thank you, old teck fascinates me... I enjoy learning more about it
Will this be able to turn on a "12V= 1.4A Maximum" solar tv?
I really don't know what that means but thats what it says on the back of it
I tried with a 9.0v==0.4A and it keeps turning off every 30 seconds.
Hi Kerry, it should work because this is 12volt and the amperage is higher than what you need. The voltage must match, but the amperage doesn't. As long as it's more than what is required (higher than you 1.4A) unfortunately the link in my description for this seller is no longer active. I'll find it again. And post it in the description for you within a couple of days.
@@ChuckTuck thank u, don't worry i saw this universal adapter in our local super market I'm gonna go buy it next week 😊
