This small piece of electronics enables you to use the Bird Monitor with a power bank that turns off when your phone is charged. With these power banks, when your phone is fully charged if you want it to start charging again you have to pull the cable out and put it back in again, or press a button. The Power Bank Enabler mimics this, waking up once per day, removing the connection for a short period of time and making the connection again, so the connected Bird Monitor can be topped up.
With the Power Bank Enabler we estimate that a Bird Monitor will last for 3 months with a 20,000 mAH power bank and indefinitely with a solar power bank.
Note the Power Bank Enabler is not waterproof and so needs to be inside a waterproof enclosure, and so is best used with a USB extension cable.
