Sunshine SS-304Q 6-Port USB Charger Review, Teardown, and Switch Modification

Summary:

This video provides a detailed review, teardown, and modification of the Sunshine SS-304Q 6-port USB charger.

The reviewer purchased the charger for 370,000 VND and unboxes it, noting its compact size compared to its advertised image.
The charger features six USB output ports: five standard 5V/2A ports (red) and one Quick Charge 3.0 port (green).
It also includes a digital display showing voltage and current for each port.
The reviewer tests the charger with a power bank [1:42] and a Samsung Note 4, observing 2.1A charging for the power bank and Quick Charge functionality (9V/2A) for the Note 4.
During the teardown, the reviewer discovers a single power output of 5V, with a boost converter IC handling the Quick Charge functionality for one port.
The reviewer notes the transformer is small and suggests the advertised 12A total output is likely exaggerated.
The modification involves adding a power switch to the charger's rear to allow for easy power cycling, preventing the need to unplug it.
This modification is performed by carefully cutting a hole in the casing [13:00] and soldering the switch to the appropriate internal wiring.
After reassembly, the modified charger is tested and confirmed to be fully functional with the added switch.

Unboxing and Initial Impressions [0:00]

The reviewer unboxes the Sunshine SS-304Q 6-port USB charger.
The charger was purchased for 370,000 VND.
The physical size of the charger is noted to be smaller than depicted on the box.
The package includes the charger unit and a power cable.

The charger has six USB output ports: five red standard ports (5V/2A) and one green Quick Charge 3.0 port.
A digital display shows the voltage and current for each port.
The reviewer plugs in the charger, and the display shows 5V/0.0A for all ports, indicating no load.
A power bank is connected to an output port, and the display shows 5V/2.1A charging [1:42].
A Samsung Note 4 is connected to the Quick Charge 3.0 port, and the display shows 9V/2A, confirming fast charging functionality.
An iPhone is also connected to a standard port, showing 5V/1A.
The reviewer mentions wanting to add an on/off switch to the charger.

The reviewer disassembles the charger to examine its internal components.
The internal circuit board is relatively compact.
The quick charge functionality is achieved through a boost converter IC, which steps up the 5V output to 9V for the QC3.0 port.
The main power output of the transformer is identified as 5V, suggesting that the advertised 12A total output for all ports combined might be an overestimation given the small size of the components.
The reviewer notes that charging multiple devices simultaneously causes the unit to get warm, likely due to the diode.

The reviewer plans to modify the charger by adding a power switch to the rear of the device.
The process involves carefully cutting a rectangular hole in the plastic casing to accommodate the switch [13:00].
The reviewer uses a drill and a utility knife to create the opening.
Wires are soldered to the circuit board to connect to the new power switch.
The switch is then installed into the prepared opening in the casing.

The charger is reassembled with the new power switch.
The modified charger is plugged in and successfully powered on and off using the newly installed switch.
The charger maintains its original functionality, including the digital display and multiple charging ports.
