Charging Compared is part of a network of independent reference sites published by one person. Charging Compared is an independent look at the operators: what a kilowatt-hour actually costs on each network, how roaming and subscription pricing differ by country, and which networks are reliable enough to plan around.
How a page gets researched
We define the question the way a reader would search for it, not the way a journal would phrase it.
We pull the literature from PubMed, weighting meta-analyses, systematic reviews, randomised trials and clinical guidelines above everything else.
We read the abstracts and, where access allows, the full text — with attention to sample size, duration, funding and whether the outcome measured is the outcome you care about.
We write the answer, then attach the citations to the specific sentences they support.
We re-check pages when a major trial or guideline lands.
What we are not
This is not medical advice, and it is not a substitute for a clinician who knows your history. Nutrition and drug research is noisy, effect sizes in free-living humans are usually smaller than the headline suggests, and almost every finding here is an average that may not describe you.
