With the popularity of smartphones,tablet PCs,laptops and other electronic devices,multi-port chargers have quickly become a new favorite in the market due to their efficient and convenient features.Analyzing the current mainstream multi-port chargers that support fast charging helps users make a more informed choice.
First of all,fast charging protocol is a set of charging standards specified by different manufacturers,which aims to shorten the charging time by increasing the voltage or current.Currently,the mainstream fast charging protocols on the market include:USB Power Delivery(PD):Developed by the USB-IF Association,it is widely used in devices from Apple,Google,Samsung and other brands,supporting up to 240W of power(PD 3.1).
Qualcomm Quick Charge(QC):fast charging technology introduced by Qualcomm,the latest version QC 5 supports 100W+ charging power.
Huawei SuperCharge(SCP/FCP):Huawei's private protocol,supports up to 66W(SCP) and 18W(FCP).
OPPO VOOC/SuperVOOC: Adopts low-voltage high-current scheme,supports up to 150W (SuperVOOC).
Samsung Adaptive Fast Charging:dedicated for Samsung devices,compatible with QC 2.0 and PD.
MediaTek Pump Express(PE):Fast charging solution from MediaTek,the latest version PE 4.0 supports 30W+.
Multi-port charger compatibility analysis
Currently,multi-port chargers on the market generally support USB PD and QC protocols,and some high-end models are also compatible with Huawei SCP,OPPO VOOC and other private protocols.
Consumer Purchasing Advice
1.Prioritize USB PD protocol:PD protocol has the widest compatibility and is suitable for multi-device users.
2.pay attention to private protocol support:if you use Huawei,OPPO and other brands of equipment,you need to confirm whether the charger supports the corresponding fast charging.
3.multi-port power allocation:some chargers will reduce the power of a single port when charging multiple devices at the same time,so it is necessary to pay attention to the actual demand.
Future Trends
With the maturity of GaN(Gallium Nitride)technology,multi-port chargers are developing towards higher power(200W+)and wider protocol compatibility.At the same time,the promotion of the USB PD3.1 standard will further unify the fast charging market and reduce consumer choice troubles.
At a time when fast charging technologies are blossoming,the protocol support of multi-port chargers has become a key indicator.Consumers should choose products with stronger compatibility according to the needs of their own devices when purchasing,in order to enjoy an efficient and convenient charging experience.
