Tested: USB Tester (Reveals Lossy USB Cables)

So, to know the real capacity of any powerbank, multiply the nominal capacity by a factor of 0.85. 20000 * 0.85 = 17000 mAh 10000 * 0.85 = 8500 mAh 5000 * 0.85 = 4250 mAh

Would this be able to tell you if the usb c cable has a 56k ohm resistor in it (like the nintendo switch pro controller cable) or if it has normal 10k ohm resistor?

Should be noted that the 5,000mah is the cell at 3.7, not output voltage. So the Wh reading should be used. If you correct for the voltage though it’s 3,416mah which is 68% efficiency, more than half but it’s alright I guess

Is the product plastic or metal

Casing is plastic, connectors have metal shielding.
