Evaluation of QC3.0 18W charger [MODEL: IET003188]

In the market environment where the supply of fast charging accessories exceeds demand, price has become one of the competitiveness of many products. Under the premise of ensuring performance, manufacturers are becoming more and more strict in controlling product costs. Especially in low-power chargers, the degree of cost refinement can be said to be determined. At this time, the only way to meet the cost requirements is through technological innovation and upgrading of the process.

At present, the author has got the 18W QC3.0 fast charging charger, and I will bring you a detailed introduction of this product below.

1.The appearance of the product.

5.Compatibility and functional testing

Real machine charging test

Aging test: Work continuously for 4 hours under the load of 3A current, there is no under-voltage or under-current, over-voltage or over-current. After working for 4 hours, the surface temperature of the charger is about 50 degrees, and it is not hot .

The voltage is 6.44V, the current is 2.99A, the power is 19.2W, and the fast charge is turned on.

The voltage is 8.9V, the current is 1.99A, the power is 17.73W, and the fast charge is turned on.

The voltage is 11.91V, the current is 1.498A, the power is 17.84W, and the fast charge is turned on.

Test summary:
For own mobile phone devices, there is no doubt that the QC3.0 18W Charger is fully compatible, with perfect handshake QC3.0 18W protocol, 5V gear, 9V gear, and 12V gear all have fast charging, which can bring a very good charging experience.
