I can say that the Ostand Power Bank has the best and most versatile stand compared to other MagSafe batteries I’ve tested. The charging experience is equivalent across most batteries, but making the Ostand hassle-free is what makes it shine.
Both models of Ostand are pretty adaptable. I’d choose the 10,000mAh for heavy-duty charging for trips, while the 5,000mAh makes for a good charger on a long day or to let a friend borrow.
