The INIU Power Bank Ultra Mini is a 10,000mAh battery with a 45W headline, priced at £29.99 and rated 4.5 out of 5 from 4,019 ratings. It sits at number four in this guide, and it is the entry where the small print helps rather than hurts: the spec table puts it at 160g, the lightest of the eight here, and marks it Portable: Yes, which is exactly where the Anker power banks in this guide contradict themselves. It is also the listing that claims to be roughly the size of an AirPods Pro case.

The numbers that do not agree are its own. The 45W on the box sits beside a spec table reading 12 Volts and 20 Amps — 240W, not 45W. Two dimension fields in the same listing swap width and thickness: 8.4 x 5.3 x 2.5 cm in one, 8.4L x 2.5W x 5.3Th cm in the other, so the thickness is either 2.5 cm or 5.3 cm depending on which line you read. The connector line lists three outputs (USB-C x2 + USB-A x1) while the port count says 2. And an "Antenna Location" field has been filled with a long list of phones. Every figure on this page comes from the Amazon listing as it stands, not from any testing of our own.

## Questions people ask

**Does the INIU Power Bank Ultra Mini really output 45W?**

The name and bullets say 45W. The same listing's spec table gives 12 Volts and 20 Amps, which multiply to 240W, so the two figures do not agree with each other.

**How heavy is it?**

The spec table lists 160 g for the INIU P50, which is the lightest of the eight 10,000mAh power banks in this guide.

**Is it small enough for a pocket?**

The listing marks it Portable: Yes and states 8.4 x 5.3 x 2.5 cm. A second dimensions field further down the same listing gives 8.4L x 2.5W x 5.3Th cm, so the thickness is either 2.5 cm or 5.3 cm depending on which field you read.

**Why does the listing have an "Antenna Location" field?**

That field is filled with the same long list of iPhone, Samsung, Pixel, Xiaomi, OnePlus and other handsets that appears under Compatible Devices. On a power bank it does not describe anything.

**What warranty comes with the INIU P50?**

The listing states a 3-year warranty, and the first bullet describes it as 3-year INIU care.

**What is in the box?**

According to the listing: INIU Power Bank 45W x 1, USB C cable x 1 and a user manual x 1.
