Normal que le connecteur usb délivre les mêmes tensions votre testeur ne fait pas le pd( power delivry) donc le port usb ne sort pas toute ça puissance
Thank you for the idea, I checked if it's possible to charge the power bank and connect a phone to it simultaneously. While it's possible to do both at the same time, it's difficult to say whether it directly transfers energy.
@@did.panas. You're welcome. In my opinion, nowadays a power bank should have such an important option, obviously if the price is low, it is hard to count on any extras + there is no point in buying a more expensive one with similar parameters :P I will say that the vast majority, if not all, have the option of charging the power bank and charging at the same time. Unfortunately, in practice, the cheaper ones do not work, I have several 1000, 2000 mh banks and when charging the power bank and the tablet at the same time, unfortunately, for example: the tablet is apparently charging, but the battery is still Tablets are declining, so it's sad, power banks range in price from $10 to $20-25, euros, so such an addition is usually added to higher models, but I could be wrong ;)
Hi there! Your test is incorrect. 20 000 mAh is at 3.7 volts, you measured 13 620 mAh at 5 volts. This powerbank has efficiency of 89% which is pretty good, so at 3.7 volts it has 17 900 mAh with conversion losses included.
Good point! Yes, power bank capacity should be expressed in watts, not mAh. Because 20000 mAh will yield different power for different voltages. In my opinion, it has become a popular trick among manufacturers - whoever states a higher number... And what's still unclear is the actual voltage to choose, 5 volts or 3.7 volts
I bought it today and it was only twenty bucks. There are others that cost forty or fifty bucks. It seems the WE-LOAD power bank is the cheapest and one cannot expect much more.
@@did.panas. No, your mixing things up now. The marking says 18 watt (power), not 18 watt-hour (capacity). The 20000 mAh is not directly related to the 18 Watt.
Excellent content, thank you. I always suspected the output was less than stated. Now we have proof.

The pass through function is missing, which is a pity :\

If we take into account the additional marking of 18 watts on the packaging, it turns out that 20000 mAh is for a voltage of 0.9 volts))
