They have lied in their listing twice. One time because the weight is 223 grams and not 203 grams (or my scale is just shitty).
And the rated output is only 2.4 amps combined and not 4.8 amps combined because when i tried to stress test it the first usb port would just go down to 0 amps when the other one is pushed to 2.4.
Also many of the one star reviews about the capacity are wrong. They use a usb tester that measures the capacity while stressing the powerbank from 100 to 0%. Their methode is flawed because when they measure capacity like that there are different factors to consider. The rated capacity of all non-fake powerbanks are for the lithium cell inside of it and not the output. When you use a powerbank the voltage gets boosted to 5V because a lithium battery has a nominal voltage of 3.7V and its safe range is 4.2V when fully charged and 3.2V when fully depleted. If you do some basic math which is 37WH/5V you come to 7.4WH or 7400 mah. The boost circuit is never fully efficient so you could expect about a 15% loss in capacity from it and 7400*0.85 = 6290mah from the output which is about as much as i got from it when testing the output capacity.
Also not 5 star because it would be way nicer if you the usb-c port could also be an output.
