Based on the textual description provided, I can't evaluate if the PCB will work or not. Here's why:

Thus, you may want to run simulations, if applicable, and/or thoroughly review the schematic and the physical layout of the PCB. All these aspects need to be taken into account when verifying if a PCB will work according to its intended purpose.

Still you could recheck these important connections:

These are some general points that should be checked for every design, but your specific circuit may also have other requirements or considerations based on its functionality.

To identify and draw the unconnected wires in your project, you should carefully examine your schematic for any components or nets that aren't connected to others appropriately.

Here is a step-by-step approach you can use in the Flux editor:

By following these steps, you should be able to resolve any unconnected wire issues in your project. If you would like specific guidance on the connections, feel free to provide more details.

The component U1 in your design is an IP5328P, which is a Fully-Integrated Bi-directional PD3.0 and Fast Charge Power Bank SOC with Multiple Input and Output Ports. Unfortunately, we don't have access to a real-time database of electronic components to suggest an exact replacement.

However, in general, when looking for a replacement, you'd want to ensure the substitute has similar or the same:

One general suggestion based on these criteria is to look for similar products from manufacturers like Texas Instruments, Maxim Integrated, or Microchip, who produce power management ICs and might have SoCs suitable for power bank applications.

Additionally, we recommend contacting your distributor or the manufacturer directly to help you find the best suitable alternative for your specific needs. This is important as it may not be feasible to find a 1:1 substitute and some adjustment in your circuit design might be needed to accommodate the replacement.
