Out of convenience, I make a parameter comparison table directly. You can see it in the bottom of this article.

Speaking of their looking , you know, all of them are designed into different shape. D2 is cube-similar. SC-608 is kind of normal cuboid. What the most special is absolutely SC-620. Geometrical shape makes it so outstanding. But to be honest, D2 is more portable.

Of course, we all look highly upon their actual performance. From the chart, you will find that the data is similar, but some individual items make themselves unique. For example, SC-620 can store the maximum discharge capacity. As for D2, the main feature is its dual channel output. It seems like two charge for one. It should be noted that they won’t interfere with each other.One for charge and the other interface can be discharged. Because of its 5V/2A USB output power from side of the unit, it can charge your mobile phone or other electronic products easily.
