Charging & USB Power Delivery
Match fixed profiles and PPS ranges, build requirements, and compare shared-port tables.
Open charging workbench →Compatibility, without the guesswork
One plug. Many hidden limits.
Check the whole USB-C, USB4, HDMI, display, and Power over Ethernet path before you buy, connect, or replace anything.
39 tools
Different decisions, not renamed calculators
8 workbenches
USB power, cables, USB4, adapters, displays, docks, HDMI, PoE
Clear limits
Known facts separated from unknowns
Start at the system
Which part of the chain are you planning?
Each workbench groups requirement, compatibility, and troubleshooting questions without blending their answers.
Cables, ports & USB data
Select requirements, preserve unknown claims, and find the assembled-path bottleneck.
Open cable workbench →USB4 & Thunderbolt
Check required feature paths and plan shared display, USB, and PCIe traffic.
Open USB4 workbench →Video adapters
Classify direction and check HDR, VRR, HDCP, audio, and DSC end to end.
Open adapter workbench →Displays, DSC, MST & lanes
Plan payload, features, compression, lane tradeoffs, and multi-display branches.
Open display workbench →Docks & hubs
Build requirements, budget power and tunnels, then compare direct and dock failures.
Open dock workbench →HDMI switches, splitters & matrices
Choose the topology, size ports, plan mixed displays and audio, then isolate distribution failures.
Open HDMI routing workbench →Power over Ethernet
Match IEEE classes, select supply equipment, plan switch and pass-through budgets, and isolate failures.
Open PoE workbench →Something already fails
Build a shortest-first isolation plan for slow charging, no power, no video, dual-display failures, and dropouts.
Build a test plan →Understand the evidence boundary
See why a declared fit is useful but still different from a measured negotiated connection.
Read sources and method →How every result works
No false certainty
Public specifications can screen a setup. They cannot reveal every vendor decision or damaged component.
Declare
Enter what the device, cable, charger, dock, or display claims to support.
Find the bottleneck
We compare the chain and show the first capability that can limit the target.
Verify the unknowns
Every result tells you what needs a manual, certified marking, hardware test, or direct connection test.
