- 17 topic guides, grouped into four routes in
- Each guide links every article inside its topic

Three ways in
If you already know which side of the question you are on, start with the matching guide set.
I am choosing a charger
For a phone, a laptop, a desk or a household. These guides work from the device you have, not from the catalogue.
I am sourcing or building
For brands and distributors taking a charger line to market, from the sourcing model through the compliance set.
I am specifying or designing
For engineers and product teams who need the protocol, the standard and the isolation requirement before the build.
By device
Start from the thing you are charging. Each guide covers one device class end to end.
Laptop Chargers
Wattage tiers, connector families, brand replacement and fleet standardisation.
iPhone Chargers
The wattage each generation draws, MagSafe and Qi2, and launch planning.
Android & Multi-Device Charging
Samsung, Xiaomi and OPPO protocols, PPS coverage and mixed-device desks.
Phone & Device Charging
Wattage tiers, fast and flash charging, and battery safety answers.
Wireless & Built-in Charging
How inductive charging works, what Qi2 changes and where the heat goes.
By technology
Start from the mechanism or the standard, rather than from a product.
GaN Charger Manufacturing
Factories, BOM decisions and the programme models behind GaN lines.
For buyers and specifiers
The commercial half: sourcing, programmes, certification and what to verify before committing.
Charger OEM & Wholesale
Sourcing models, landed cost, supplier qualification and program gates.
Wireless Charger Products & OEM
Form factors, mould decisions, certification and wholesale buying.
Laptop Charger OEM & Fleet Programs
Platforms, fleet standardisation and total cost of ownership.
By use case
Where the charger has to survive a specific environment rather than a specification sheet.
Medical Power Supplies
IEC 60601, MOPP isolation, the document set and factory qualification.
Travel Chargers & Plug Adapters
Plug types, voltage limits and multi-region product lines.
How these guides are built
Four rules that apply to every guide on this page.
One head term per guide
Each guide covers a topic a buyer would actually search for, not an internal label like Resources or Insights.
The whole topic, not a sample
A guide links every article inside its topic. If an article is not linked, it is not covered.
Two clicks, not five
Every article sits within three clicks of the home page, and most are two.
Written, not aggregated
Each guide is hand-written prose with a verdict in every section. A list of links is not a guide.

About these guides
Two questions we get asked about the guide set itself.
What are these guides for?
They exist so a buyer, a product manager or an engineer can move from a question to the specific article that answers it without searching a flat blog archive. Each guide covers one head topic and links the articles inside it.
How often are they updated?
As new articles are published and as standards change. The guide is the maintained entry point; the articles underneath carry the detail.
Cannot find the topic?
Send us the question rather than the search term. If it is a topic we have not covered yet, that is useful to know and we will answer it directly.
