Why Are More And More Cell Phone Brands Introducing Dual-Port Chargers? | ZONSAN

2023-03-23 Why are more and more cell phone brands introducing dual-port chargers?

A long, long time ago, chargers for electronic products were complimentary with the purchase of the machine, and the voltage and interface were not common among different devices. Nowadays, most consumers have several digital products at home, which makes the former mainstream single interface charger obsolete.

Third-party digital brands began to launch dual-port, or even multi-port chargers early, and as the original cell phone brands, in fact, only recently joined the ranks of dual-port chargers. Apple, Huawei, Xiaomi, VIVO and other cell phone brands have launched dual-port chargers, compared to the traditional single-port chargers, they support single-port high-power output, dual-port simultaneous fast charging, and even simultaneously take into account the private protocol and universal PD fast charging, can be described as full of practicality.

New digital products are constantly on sale, old chargers are constantly being phased out, and cell phone brands such as Samsung, Apple, and Huawei are gradually eliminating their charger distribution, giving the dual-port fast charging market an immeasurable amount of hard demand. Watching third-party digital brands create one explosive fast charger after another, cell phone brands also began to sit back and began to launch the original dual-port charger, with more stable quality, compatible with their own private protocols and other advantages, the market ushered in a piece of praise, but also more cell phone brands to join the dual-port charger market. Let me introduce you to these cell phone original dual-port chargers have what selling points.

ZONSAN Summary

No matter single-port charger or dual-port charger, they are all a branch of the fast charging market, which is the result of market segmentation and proves that the global fast charging market tends to be red-hot. In terms of universal fast charging, each dual-port charger is compatible with PD universal fast charging, which can provide high-power charging for large digital devices such as laptops when used in a single port, and dual-port charging at the same time, and can do dual devices together with fast charging, the best of both worlds.

While mainstream digital products are compatible with USB PD fast charging, most cell phone brands use their own private fast charging protocols and cannot reach higher power using PD fast charging. The original dual-port chargers launched by cell phone brands generally include support for private fast charging protocols, and the original products have an absolute compatibility advantage over third-party brand chargers, so cell phone brands have entered the market to compete with third-party brands for market share.
