About Pi Power Estimator

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

It has the following features :

- Select Model A, B, A+, B+, Pi 2, Pi 3 or Pi Zero
- Select different capacities of USB power banks from 2200 to 20000mAh
- Select different AA/AAA cell capacities and voltages
- 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 and Pi 3
- 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 HDMiPi 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 set to use Portrait mode.

This app does not contain any adverts but does contain some clearly described links to RaspberryPi-spy.co.uk and my social media channels. These are directly related to the Raspberry Pi.

I updated to the new version and i cant scroll down in any of the pages so i cant add any wildcards/activities/options etc

S70%

Usefull app. Please add specs for wifi/bluetooth on the Pi zero W.

Very precise tool

W70%
by W####:

Simple, straightforward app good for basic power estimations. Could benefit from having an input for the battery capacity rather than a bunch of random presets, especially with new battery packs going over 20,000mAh. Overall though not bad.

Z70%

Dont have Pi 2, dont have 18650 battery options and usb device more options. If I make portable pi2 for somethink I will make costume power sorce.
