Powerbankifier

This tool turns your device into a monitorable powerbank. If it has a port that sends power, you can plug it into a device to power it.

Once you create a code, your battery info is logged on the server with the code as the key. This makes your device the transmitter. You can connect to the code to receive battery info and notifications.

You can also prevent your powerbank from shutting off using the wake lock feature.
