1. Voltage and current output are different :PD chargers usually output voltage of 5V or 12V, while GaN chargers can output higher voltage and current. For example, some GaN chargers can output up to 60W, while PD chargers can usually only output 30W or less.
2. Different charging speeds: Since GaN chargers can provide higher voltages and currents, they can usually be charged in less time. For example, a 60W GaN charger can fully charge a fully charged phone in less than 2 hours, while the same PD charger may take much longer.
3. Safety is different :GaN chargers generally have higher power handling capacity, so they can operate in a safer situation. For example, PD chargers can overheat when they exceed their rated power, while GaN chargers can avoid this.
4. Price difference: Because GaN chargers have higher power handling capacity and better security, they are generally more expensive than PD chargers.
In summary, the difference between PD chargers and GaN chargers is mainly in terms of power handling capacity, charging speed and safety. It is necessary to choose the appropriate charger according to the specific use needs.
The main difference between Bex 20W gallium nitride and PD fast charge is the charging speed and charging protocol. Bex 20W gallium nitride charges faster, using the latest gallium nitride technology, charging power density is higher, and you can fill the battery faster. PD Fast charge is a charging protocol that can charge devices in a more efficient way while supporting the charging needs of a variety of devices. In addition, Bex 20W gallium nitride also has the advantages of small size, light weight, good heat control, etc., easy to carry and use. In general, Bex 20W gallium nitride and PD fast charge have their own advantages, which one to choose depends on individual use needs and habits.
