## Before you buy

- The listing calls this model 22.5W, while its feature copy refers to a 2025 version and PD 10000 without confirming that version applies to BI-B61. It also lists a 12 Volts rating and a 3-hour battery charge time without clarifying operating conditions or the charger used. Confirm the selected model's charging specifications and port behaviour before purchase, especially if simultaneous charging speed matters.

## A good fit for

- Phone users wanting a compact backup battery for daily carry or travel.
- Buyers who may need to connect several devices and value a listed digital display.

## Less suited to

- Buyers needing a clearly documented high-capacity option for extended use away from mains power.
- Anyone who needs confirmed charging speeds for multiple devices at once or model-specific fast-charge compatibility.

## Customer feedback

Customer feedback highlights quick phone charging, pocket-friendly size, light weight and travel portability. Some customers report getting up to two phone charges, but results depend on the device and use. Reliability feedback is mixed, including reports that units stopped working within a year. This is relevant for a frequently carried backup battery, and the positive experiences do not establish a guaranteed lifespan or charging result.
- Positive themes: Customers praise charging performance and speed.
- Positive themes: Customers like the compact size, portability and lightweight design.
- Positive themes: Some customers report good battery life and consider it worth the money.
- Negative themes: Some customers report reliability problems, including the power bank stopping within a year.
- Mixed feedback: Feedback on reliability is mixed.

## Frequently asked questions

### How much capacity does the INIU BI-B61 list?
The listing specifies 10000 Milliamp Hours. This is the stated battery capacity, not a guarantee of a particular number of full phone charges.
### How many devices can it charge at once?
The product copy claims that three devices can be charged together through the USB-C and USB outputs. The listing does not specify how power is divided between connected devices.
### Is the USB-C port an input as well as an output?
The feature copy describes USB-C input and output. Check the selected listing and model details, as the copy also refers to a 2025 version without clearly tying that revision to BI-B61.
