## At a glance

- The title claims 22.5W output with PD 3.0 and QC 4.0 fast-charging support.
- USB-C is described as both an input and output on the 2024 version listing.
- Digital display and flashlight are listed alongside a slim design.
- Manufacturer copy gives device-specific charge examples, which vary by device and should not be read as a guaranteed number of full charges.

## Pros

- 10,000mAh capacity and a stated 210g weight suit a compact everyday or travel backup.
- USB Type A and USB Type C connectors are listed, and the USB-C port is claimed to handle both input and output.
- A digital display offers a charge-level readout, with a flashlight also listed.

## Cons

- The 10,000mAh capacity is a modest reserve for extended use or charging multiple devices repeatedly.
- The supplied details do not specify output wattage per port or how charging performance changes when multiple ports are used.

## Before you buy

- The listing describes a 10,000mAh battery and 22.5W fast charging, while the detail fields list 5 Volts and 3 Amps without assigning these values to a particular port or charging mode. It also calls the product slim and supplies dimensions of 13.6 x 7 x 1.5 centimetres and a weight of 210 Grams, but gives no comparative basis for slimness. USB-C input and output is described specifically for the 2024 version, so confirm the selected revision. The explicit package list names a power bank, travel pouch, USB C cable and manual, while a separate claim mentions a case without confirming it as included.

## In the box

- Power bank ×1 (Included)
- Travel pouch ×1 (Included)
- USB-C cable ×1 (Included)
- User manual ×1 (Included)
- Case (Check selected pack): Mentioned separately, but not listed in the explicit package contents. Check the selected listing.

## A good fit for

- People wanting a pocketable 10,000mAh backup for phones or earbuds.
- Travellers who value a listed USB-C input/output port, display and flashlight.

## Less suited to

- Buyers needing a high-capacity reserve for several days away from mains power.
- Buyers who need a clearly stated per-port output or confirmed simultaneous charging behaviour before purchase.

## Customer feedback

Customer feedback highlights quick phone charging, portability and useful battery life, with positive comments also describing the power bank as lightweight. Experiences with battery life are mixed, including a report of the unit stopping after a month. These impressions are relevant to a 10,000mAh travel backup, but they do not establish a typical lifespan or guarantee performance for a particular device.
- Positive themes: Customers describe charging phones quickly and find the unit portable and handy for travel.
- Positive themes: Customers positively mention its weight and useful battery life.
- Negative themes: One reported experience says the power bank stopped working after a month. This is an individual concern, not evidence of a universal reliability issue.
- Mixed feedback: Battery life is described both as lasting for hours or multiple uses and as disappointing by some customers.

## Frequently asked questions

### What is the capacity of the INIU BI-B6?
The listing specifies a 10,000mAh capacity. Its charge count depends on the device and conversion losses, so the stated capacity does not translate directly into an equal amount delivered to a phone.
### Does the BI-B6 have USB-C input and output?
The product copy says USB-C supports both input and output on the 2024 version. Confirm that the selected listing is for that revision.
### What accessories are included?
The explicit contents list names one power bank, one travel pouch, one USB-C cable and one user manual. A separate case mention is not confirmed by that list.
### How long does recharging take?
The details list a 3-hour battery charge time. Another manufacturer statement says 2 hours with an 18W wall charger via USB-C, so recharge time depends on the charger and the listing's claims are inconsistent.
