Ultimate Charging Guide
Everything about USB-C, wireless charging, power banks, and GaN chargers — demystified for non-techies.
The Anker Prime 100W is the 3-port GaN charger we recommend for a typical Apple-ecosystem desk. 100W total with smart allocation: 100W to a single laptop, or 65W + 30W split when you add a phone, or 45W + 30W + 20W with all three ports populated.
Smart allocation matters
Cheaper multi-port chargers split wattage statically — plug in a phone and the laptop suddenly charges slower even if the phone only wants 20W. The Prime 100W detects each device’s actual request via USB-PD handshake and only reallocates what the device actually needs. Our MacBook Air stayed at 65W even with a 5W AirPods plugged in alongside.
OLED display tells you the truth
Every port shows live wattage on the front OLED. If your cable is downgrading the handshake (a common failure mode with cheap USB-C cables) you see it immediately. This single feature has saved us hours of “why is this charging slow” debugging.
Thermal performance
At sustained 100W to a single MacBook Air the case temp on our bench hit 52°C at 30 minutes — well within safe for closed-laptop-bag travel. GaN III efficiency measured at 90.1%.
Bottom line: The 3-port 100W pick at $69. Smart allocation + OLED + compact size = the new standard for multi-device charging.
