What Is USB Power Delivery (USB PD)?

USB Power Delivery is the universal fast-charging standard that lets a single cable negotiate up to 240W between a charger and device — making wattage, cable quality, and connector type the three things that actually matter.

⚡ Featured: High-wattage USB PD cables from BIG+
BIG+ 240W Magnetic Cable (2 Pack) — Supports full 240W USB PD; ideal for laptops, tablets, and fast-charge phones.
BIG+ 100W Magnetic Cable (2 Pack) — 100W USB PD for MacBooks, iPads, and Android flagships.

PPS (Programmable Power Supply) Explained

PPS goes a step further than standard USB PD by allowing the charger and device to negotiate voltage in fine increments, reducing heat and improving efficiency — especially on Samsung Galaxy and select Android devices.

How to Choose the Right Charger and Cable

The weakest link in your charging chain limits your speed. A 100W charger paired with a 60W cable will max out at 60W. Always match your cable's rated wattage to your charger and device.
