Price and rating as shown on Amazon when we collected them. Both change.
This is the second INIU in the ranking and the faster of the two: the listing describes 45W fast charging from a 20000mAh battery, which is enough to charge a phone at its top rate and to make a real dent in a laptop or tablet through USB-C Power Delivery.
That 45W matters more than the capacity for laptop users, because it is the figure that decides how long a top-up takes rather than how many top-ups you get. At the time of collection the pack carried 8,659 ratings at 4.4 stars, a smaller sample than the cheaper INIU above it. Everything here comes from the Amazon listing rather than our own testing.
How those 8,659 ratings break down
An average hides its own shape. This is the spread behind the 4.4 stars.
