    It’s heavy and feels like 20,000 mAh. I haven’t used it since I bought it. I’m charging it. It looks good. I look forward to using it.

    The quality of the power bank is guaranteed, with sufficient battery storage. It has a fast charge of 30W, which is easier to use than the previous regular version. It has an Apple Android port and a Type-C port that supports 30W. The size is not large, so you no longer have to worry about your phone running out of battery
