Pi Power Estimator allows you to calculate the run-time of a Raspberry Pi running from a USB power bank, set of AA/AAA batteries or a single PP3 9V battery.

It has the following features :

- Select Model A, B, A+, B+, Pi 2, Pi 3, Pi 4 or Pi Zero
- Select different capacities of USB power banks from 2200 to 20000mAh
- Select different AA/AAA cell capacities and voltages
- Select PP3 9V battery capacities
- Choose from a set of features that affect energy use such as Ethernet, HDMI and WiFi
- Choose the number of cores in use for the Pi 2, Pi 3 and Pi 4
- Choose from a set of "wildcard" current values to accommodate other add-ons and accessories
- Display some raw data for reference

The calculation presents a time range to give a reasonable estimation of the run-time assuming the battery is healthy.

The current consumption of the Pi and the options selected are based on real measurements and not merely plucked from a manufacturers datasheet. This makes a more sensible average rather than being a peak current draw which gives unhelpful estimates.

When available you may want to power the official Pi Screen from the same power bank so that is listed in the "Features" so you can calculate an estimated time with that hooked up as well. In order to keep the interface as simple as possible this is the only Pi accessory I have specifically included but the wildcard options should cover anything else you may want to use at the same time.

The app is designed to work best in Portrait mode.

Pi Power Estimator允许您计算从USB移动电源，AA / AAA电池组或单个PP3 9V电池运行的Raspberry Pi的运行时间。

它具有以下功能：

- 选择型号A，B，A +，B +，Pi 2，Pi 3，Pi 4或Pi Zero
- 从2200到20000mAh选择不同容量的USB移动电源
- 选择不同的AA / AAA电池容量和电压
- 选择PP3 9V电池容量
- 从一组影响能源使用的功能中进行选择，如以太网，HDMI和WiFi
- 选择Pi 2，Pi 3和Pi 4使用的核心数
- 从一组“通配符”当前值中进行选择，以适应其他附加组件和附件
- 显示一些原始数据以供参考

该计算给出了一个时间范围，以假设电池是健康的，给出合理的运行时间估计。

Pi的电流消耗和所选择的选项基于实际测量，而不仅仅是从制造商数据表中获取。这使得平均值更合理，而不是作为峰值电流消耗，这给出了无益的估计。

如果可用，您可能需要从同一个移动电源为官方Pi屏幕供电，以便在“功能”中列出，这样您就可以计算出连接时间的估计时间。为了使界面尽可能简单，这是我特别包含的唯一Pi配件，但通配符选项应涵盖您可能想要同时使用的任何其他内容。

该应用程序旨在最佳的纵向模式。
