Key Benefits

Why Buyers Specify This Model

01

Two Ports, Different Current Levels

The 5V2.4A port suits standard smartphones and tablets, while the 5V3.4A port supports devices that can draw more current, such as larger tablets or older models with fast-charge capability.

02

Smart Current Allocation

The charger detects the connected device and allocates the appropriate current to each port, preventing overloading and ensuring stable charging.

03

Dual Country Production

The same design is produced in both China and Vietnam. Buyers can choose the origin to reduce or avoid tariffs tied to China-made goods.

04

Compact Design for Vehicle Use

Small enough to fit in tight spaces, this car charger stays out of the way while charging multiple devices on the go.

Problems It Solves

What This Product Fixes

One Charger Can’t Serve Two Devices at Full Speed

Many dual-port chargers split current equally, slowing down one device. This model assigns different current levels per port to match device needs.

China-Origin Tariffs Impact Product Cost

Sourcing from Vietnam avoids exposure to China-origin tariffs, helping maintain competitive pricing in markets with trade restrictions.

Charging Speeds Vary by Port

Without smart current management, some ports underperform. This charger uses intelligent detection to deliver the right power to each device.

Technical Features

How It Is Built

Dual Output Ports with Independent Current Control

Each port operates independently, with one delivering up to 5V/2.4A and the other up to 5V/3.4A, based on device requirements.

Built-in Protection Circuitry

Includes over-voltage, over-current, over-temperature and short-circuit protection to safeguard both the charger and connected devices.

Aging Test Before Shipment

All units undergo in-house aging tests before packing to identify early failures before they reach the customer.

Detachable USB Cable Option

The USB cables are detachable, allowing one charger to serve multiple device types by swapping cables.
