Inui Power Bank Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

INIU is the best-performing inui power bank brand in July 2026, moving 61,000 units across 7 ASINs for 72.6% of Top 10 volume. Anker follows with 16,000 units (19.0%), ahead of OHOVIV on 7,000 units (8.3%).

With 3 brands splitting the Top 10 and 100.0% of volume sitting with three of them, this is a concentrated shelf — the leaders hold multiple listings or one very high-velocity ASIN, so a new entrant competes against established review moats rather than an open field. Average selling prices among the leaders run from $24.88 to $77.99, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. Specifically, one ASIN forced its way in: B0FX7T4H7D booked 10K units at $26.96, with ▲ 150.0% MoM change. On the growth side, B0GJ5YNBNJ leads positive momentum with ▲ 400.0% MoM growth on 500 units, with B09176JCKZ close behind at ▲ 100.0% MoM on 2K units.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
