Confirm the selected model's charging specifications and port behaviour before purchase, especially if simultaneous charging speed matters.

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.
