Manta 5000mAh Power Bank Incomplete Charging - Not Sufficient for Full Phone Charge

Question

Hello, I do not know if it's a good group, if not I ask for a hint where I am supposed to be guided and so I bought a power bank Manta 5000 mAh after charging it I plug it into the phone and it only charges 50% and it's already discharged, is it possible with 5000mAh is not enough for...

Very possible because this powerbank has only written that it has 5000mAh and it really has about 1500-2000 probably. Provide a photo or model of this invention. If you have the option, give it as a non-compliance of the product with the description.

Power Banks have Li-Ion accumulators, their voltage is about 3.7V powerbank is equipped with inverter which raises this voltage to 5v, no converter has 100% efficiency, I have a powerbank of 20,000mAh (3.7v) but it has only 12,700mAh per 5v and this is due to the fact that it charges you to about 50% simply, the producers give how much capacity they have batteries installed in their power banks, and not how much power the bank can give away. greetings

In part you are right but such a big loss can not just put the li-ion links in this range and so much in the subject (20A x 3.7V = 74W and 12.7A x 5W = 63.5W or efficiency of about 85% au a friend with a manta will probably come out with 30% so it is not an inverter). People are unaware that when they use the phone and simultaneously charge it, it consumes more mAh than it is written on the battery in the phone.
