FAQ

Q: How to set battery capacity, Full voltage, low voltage?

A: It only affects the charging method and the calculation of the charge level, the protection threshold, and does not change the actual battery parameters. more info please refer to: [ github.com/geeekpi/upsplus/issues/80 ]

Q: Why it will turn on my Raspberry Pi once I plug the power supply into the charging port?

A: When the BACK-TO-AC function of the Raspberry Pi is turned on, the Raspberry Pi will be automatically activated when the external power supply is connected to the charging port. This setting is for some applications that use the Raspberry Pi as a server scenario, because the external power supply After the power is supplied, the UPS detects the charging status and executes the automatic startup operation, so that some scenes where the Raspberry Pi is placed in the computer room can easily start the Raspberry Pi, no need to press the button to start the UPS, if you want Using BACK-TO-AC, you can also turn off this function. After turning off this function, you need to press the power button again every time you start it.

Q: Why does my UPS shut down suddently and I can not turn it on?

A: Please use power supply with QC protocol and try to change batteries with better quality. we recommend you to connect QC power supply while your UPS need to provide service at 7x24.

FAQ

Q: Why does the battery light go off sometime and lights up in a while?

A: This is because the power chip performs battery re-sampling, and the purpose is that the data of inferior batteries is inaccurate during the sampling process.

Q: Why is the power cut off every once in a while?

A: Please check the battery charging current, the data discharge direction or the charging direction. If the load is too large, the charging may not be enough, which will cause this problem.

Q: What kind of wall charger should I use?

A: If the load is normal, it is recommended to use an ordinary 5V@2A charging head. If you need to carry a slightly higher load, it is recommended to use a fast charging source. We support FCP, AFC, SFCP protocols Fast charging source.

Q: Can I directly input 9V and 12V to the USB port?

A: No, if you must do this, you must remove the DP, DM and other related detection pins, and ensure that the power supply is stable.

Q: I heard howling, why is this?

A: Because of the no-load protection mechanism, the howling will disappear after the load is installed.

Q: using firmware v. 4, when AC power comes back on during the shutdown countdown, I realized that the 5V supply for the raspberry pi is not switched off at the end of the countdown. so, after shutdown of the operating system, the raspberry pi will never restart automatically.

IMHO the following would be better: once a shutdown countdown starts, and we have the Back-To-AC Auto Power UP flag set, then: the shutdown sequence should proceed to its end, switch off the 5V-power for a certain time (a couple of seconds maybe), regardless of AC Power. switch the 5V back on when AC power is restored. otherwise, I am very happy with the product. one more thing: would be nice to have some sort of alert for new firmware releases and release notes for these.
