My review:
It arrived well packaged in a retail box and inside you get the Powerbank, USB-C to USB-C Cable and Instructions.
This is certainly a solidly made and somewhat weighty portable charger and measures approx. 15.5cm x 7.4cm x 2.5cm.
It has a USB-C port, which doubles as a charging port (IN) for the charger and a charging port (OUT) to your device. Then there is a USB QC port for single or dual charging of devices.
In terms of charging the charger up, I tested this, and it was around the 50% mark and charging at 20V, 3A, 60W from a 61W fast charger.
I tested the charging performance with two of my devices and the results were as follows:
Samsung Galaxy S21 Ultra (26% Battery Charge)
Output USB-C PD: 5A
Output USB QC: 2.8A
Samsung Galaxy Tab S7+ (67% Battery Charge)
Output USB-C PD: 5.2A
Output USB QC: 2.4A
Bearing in mind that fast charging is classed as anything equal to or above 2.4A. These were the highest Amps rates I have got out of any charger/powerbank. The single charge via the USB-C PD was blisteringly fast.
I then gave it a go with charging the two devices simultaneously, with the charging rate of the USB QC port dropping off by around 50%.
Dual Charging
USB QC Samsung Galaxy S21 Ultra (33% Battery Charge): 1.5A
USB-C PD Samsung Galaxy Tab S7+ (67% Battery Charge): 5.2A
Whichever device I plugged the USB QC into, got that lower charge rate.
The reason for this drop off on the USB QC is down to the fact that the total output of this charger is 65W and the USB-C can take up all of that. So, it looks like when two devices are charging simultaneously, priority is given to the one connected to the USB-C PD port.
The battery capacity of my devices is Galaxy Tab S7+ 10,090mAh and Galaxy S21 Ultra: 5,000mAh. That means this 20,000mAh charger can put one full charge through on my tablet and two on my phone or in other combinations.
I honestly cannot fault the power delivery on the USB-C and the fastest I have personally seen.
I hope you found this review & photos interesting, informative, and useful. Thanks for reading.
