To determine whether a power bank is suitable for your Celestron Advanced GT mount, you need to consider the power requirements of the mount and the specifications of the power bank. The Celestron Advanced GT mount typically requires a 12V DC power supply with at least 1.5A current (1500mA).
Check the output voltage and current rating of the power bank. It should match the 12V requirement, and the total current output should be at least 1.5A to ensure proper operation. Most power banks are designed to charge smaller devices like phones or tablets, so they usually output 5V, which would not be suitable. You’ll need to find a power bank specifically designed to support 12V output. Additionally, confirm that the power bank has the appropriate connector or comes with an adapter that fits the mount’s power input.
Finally, consider the capacity of the power bank measured in milliamp hours (mAh). To estimate how long the power bank will last, divide its capacity by the mount’s current draw. For example, a 10000mAh power bank at 12V should provide approximately 6.7 hours of operation (10000mAh / 1500mA = 6.67 hours), assuming 100% efficiency, which is rarely the case, so expect slightly lower performance.
