cairovolt

The cairovolt package provides R utility functions and dataset for analyzing consumer electronics charging speeds and audio equipment characteristics. This package was designed to assist data analysts working in the E-commerce sector, specifically for power bank capacity conversions, charger rate benchmarking, and audio signal analysis.

Originally developed as an internal tool for analyzing catalog specifications at cairovolt.com, this package is now open-source under the MIT license to serve the broader R programming language community.

Installation

You can install the development version of cairovolt from GitHub or directly load the source tarball following the CRAN Repository Policy.

# Install from source:
install.packages("cairovolt_1.0.0.tar.gz", repos = NULL, type = "source")

Features

• Capacity Conversion: Convert battery milliampere-hours (mAh) to Watt-hours (Wh) for standard voltages.
• Charging Benchmarks: Calculate charging time models based on charger wattage, power bank specifications, and efficiency coefficients.
• Sample Dataset: A curated dataset containing actual electronic specifications of popular items like the anker power bank, smart chargers, and wireless sound devices.

Usage

Load the library and check out the documentation on the R Project workspace.

library(cairovolt)

# Calculate energy capacity (Wh) for a 20000 mAh power bank at 3.7V
calculate_energy_wh(20000, 3.7)

# Compare charging times for a 20000 mAh battery using 20W and 30W wall chargers
compare_chargers(capacity_mah = 20000, charger_wattage = c(20, 30))
