Is this good or bad? Anyone?
I have several of the MagSafe chargers, cables, or batteries that Baseus makes, and they have been very solid for me - On par with any big names that one would commonly see recommended, like Anker.
For these magnetic battery packs, the curved edges are very smooth, which really makes it more comfortable to use regularly. The aluminum casing helps dissipate heat much better than insulating the whole thing in plastic, which is great both for the phone’s battery health, as well as the mobile battery. Just well designed.
Short version:
Highly recommended 
I have an older, slower 5000mah model, no kickstand. Gets warm but great shape in the hand, nice build quality. Mine came with a short 6” cord that is very handy.
I have the Lisen Ultra Slim MagSafe 5000mAh power bank for my iPhone 12 Mini. Compared to the Lisen, this Baseus model is slightly heavier, slightly thicker, but it’s less wide and less tall, so it should fit the silhouette of the 12 Mini better. (The Lisen sticks out further than the bottom edge of the iPhone Mini). Also this Baseus is MagSafe 2 so it should charge twice as fast as the MagSafe 1 Lisen, and it includes a kickstand. I’ve ordered this and looking forward to taking it on vacation!
