I have used a similar battery (Samsung's 30Q 20A 3000mAh) and as far as vaping goes the performance feels about the same. I use a single battery mod set up with a .5ohm coil on a decent tank. The only difference I can see is that this battery has lasted much longer than the one I'm comparing it to.
Four stars because like to reserve the fifth star for products that are in some way revolutionary or just in a league of their own.
This is a good battery. It's the third one that I have purchased in the past year and half or so and so far the other two that I have still function as good as they did when they were new.
I have gone through several brands of batteries in the last four years that I have been vaping and as of today this is the one I find the most value in.
