Generic USB Power Bank
This part uses a USB-A style connector purely as a visual placeholder — it doesn’t represent any specific connector type. The actual hardware might use USB-A, USB-C, micro-USB, or no standard connector at all. What matters is the electrical function: a portable power source, not a specific commercial product. This keeps the part useful across the widest range of projects, regardless of what connector your real power bank actually has.
Why only power pins (VCC/GND), no data lines:
This part models a power bank used purely as an energy source for microcontrollers, LED strips, and similar low-voltage electronics — not as a data peripheral. USB data lines (D+/D-) only matter for charge negotiation (QC/PD) between the bank and a connected device, which is irrelevant here. Including them would leave permanently unconnected pins in every schematic — clutter with no benefit.
Why adjustable voltage, current, and capacity properties:
Not every “power bank” outputs a fixed 5V. Bare 18650/21700 battery holders, for instance, have no boost converter and output raw cell voltage. Rather than creating a separate part for every voltage/chemistry combination, this part exposes voltage, current, and capacity as editable properties — so it accurately represents whatever real hardware you’re actually using, USB-regulated or not.
Why 3 ports, and why you don’t have to use all of them:
The 3-port layout covers common multi-port power banks, but nothing forces you to wire all three. A single-port bank can be represented just as validly by using only 1 or 2 of the available pin pairs and ignoring the rest.
Why there’s no functional PCB view:
A power bank’s outputs are never soldered in a fixed relative layout — each output is wired independently, often to entirely separate boards, with no fixed dimensional relationship between them. Giving this part real copper pads in the PCB view would falsely imply a fixed physical footprint that doesn’t exist in reality, and could mislead a PCB designer into routing around a constraint that isn’t real. The PCB view instead displays a clear “not supported” notice — wiring via flying leads is the intended and only correct approach.
