Charge faster and safer with the right charger and cable—explained in minutes._
1) What is USB‑C PD?
- USB Power Delivery lets your device and charger “negotiate” the safest, fastest combo of voltage/current (e.g., 5V/9V/12V/15V/20V).
- PPS (Programmable Power Supply) is a PD feature that fine‑tunes voltage on the fly—great for phones like Samsung Galaxy for cooler, faster charging.
2) Wattage matching (phones, tablets, laptops)
- Phones: iPhone typically 20–35W; many Android phones 18–45W (look for PPS for 25–45W on Samsung).
- Tablets: Usually 20–30W.
- Laptops: Ultrabooks 45–65W; performance/pro laptops 90–140W+.
- Tip: A higher‑watt PD charger won’t “force” extra power—your device only draws what it needs.
3) Cable ratings (60W vs 100W, e‑marker chips)
- 60W cables = 3A max; 100W cables = 5A and require an e‑marker chip for safety.
- USB PD 3.1 now supports up to 240W—look for “EPR 240W” on newer cables/chargers if you need it.
- Data speed (USB 2.0 vs USB 3.x) doesn’t determine charging speed—amps/watts do.
4) Chargers: single vs multi‑port
- Single‑port = full wattage to one device.
- Multi‑port = shared power; look for “dynamic power allocation” so multiple devices charge efficiently.
- GaN chargers run cooler and pack more power in smaller sizes.
5) Safety tips and common myths
- Use certified chargers/cables (USB‑IF, reputable brands). For Lightning, look for MFi.
- Avoid covering your phone while fast charging; heat slows charging and ages batteries.
- Myth: “Higher‑watt chargers damage phones.” Reality: PD only delivers what your device requests.
- Myth: “USB‑A ‘fast’ equals PD fast.” Not necessarily—PD over USB‑C is more standardized and often faster.
