USB-C Cable Ratings Explained: What 3A and 5A Actually MeanMar 1,2026This article explains what 3A and 5A USB-C cable ratings actually mean, how current capacity affects charging speed and stability, and why choosing the right cable depends on charger output, device protocol, and overall compatibility.- PD vs PPS Explained Simply: Which One Is Better for Daily ChargingFeb 28,2026PD and PPS are both fast charging technologies, but they behave differently in daily use. This article explains how fixed power steps in PD compare with dynamic adjustment in PPS, and why PPS often delivers more stable charging with lower heat for everyday use.
- Why Some Chargers Make Touchscreens Go CrazyFeb 2,2026Some chargers can cause “ghost touches” and erratic scrolling because of poor power quality. Electrical noise (ripple), weak isolation/filtering, unstable grounding, and voltage swings from low-quality cables can interfere with the touchscreen controller, especially as the phone warms up while charging. This article explains the real causes and gives quick tests to identify whether the charger, cable, or wall outlet is the culprit.
- Charger Wattage Myths: 65W Is Not Always Better for PhonesJan 27,2026A 65W charger is not automatically faster for phones because wattage is only a maximum capability. Real speed depends on whether the charger supports the phone’s preferred fast-charging protocol (USB-C PD or PD PPS), the cable’s current rating, the battery’s charging stage, and thermal throttling when the phone or charger gets hot. This article explains why some lower-watt chargers can feel faster in real use and how to choose a charger that stays stable and cool.
- Why 20W Feels Slower Than 18W: Fast-Charge Negotiation in Plain EnglishJan 23,2026A 20W charger can feel slower than 18W because wattage is only a maximum. Real fast-charging speed depends on protocol negotiation between the phone and charger, cable resistance, battery charge stage, and thermal throttling when the phone gets hot. This article explains the handshake logic and a quick test to identify the real bottleneck.
- Power Banks and Your Phone Battery: What You Need to KnowJan 22,2026This article addresses common concerns regarding the impact of power banks on smartphone battery health, debunking the myth that all power banks are detrimental. It emphasizes that high-quality, certified power banks are safe, incorporating advanced safety features like overcharge, over-current, short-circuit protection, and temperature control. The true culprits behind battery degradation are identified as low-quality, uncertified chargers, as well as user habits and environmental factors. Key
