Two devices with the same wattage rating can charge at very different speeds. The reason is protocol negotiation.<\/p>\n
Power Delivery is the common standard<\/p>\n
USB Power Delivery allows charger and device to agree on voltage and current. Without support on both sides, the device falls back to a slow default. Look for explicit PD support rather than a bare wattage number.<\/p>\n
A cable can be the bottleneck<\/p>\n
Many cables carry limited current or lack the internal wiring needed for higher voltages. A 100W charger paired with a low-rated cable charges slowly. If a cable advertises high wattage, check whether it also supports the data rate you need.<\/p>\n
Port sharing reduces output<\/p>\n
Multi-port chargers split their total output. A charger rated at 65W may deliver far less to one port when another device is connected. Look for per-port ratings rather than a single total.<\/p>\n
GaN makes chargers smaller, not necessarily better<\/p>\n
Gallium nitride designs run cooler and allow smaller bodies, which is genuinely useful for travel. It does not change the protocols supported.<\/p>\n
Safety markings<\/p>\n
For mains-powered electronics, look for recognised safety certification. A charger with no identifiable certification is a risk, not a bargain.<\/p>\n
