Iba reakcia na recenziu zo 17.10.2021 a kapacitu PowerBaniek (keďže nejde reagovať priamo na recenziu) Píšete, že vám merač pri nabíjaní ukázal 3500mAh = 3,5 Ah ... -treba ale uvážiť, že to bolo nabíjanie napätím 20 Voltov (V) takže 20 (V) x 3,5 (Ah) = kapacita 70 Wh to je na strane batérie (ak zanedbáme straty) 70 Wh / 3,7 V (nominálne napätie batérie) = cca 19 Ah (19 000 mAh)...čiže kapcita ako-tak sedí.

Je tato nabíječka schopná bezpečně nabíjet HP 450 5G pro?

Je v parametrech uvedeno, že výstupní napětí je 20V. Pokud ale vím, tak USB napětí je 5V. Jak to tedy je?

Dobrý deň, dokáže tento powerbank nabiť aj laptop (IdeaPad flex 5 14ITL05), alebo sa bude naopak nabíjať powerbank z laptopu ako to je pri menej výkonných powerbankoch. Nabíjací adaptér laptopu má 65W a laptop má aj USB-C PowerDelivery port, čiže teoreticky by to ísť malo, ale už som mal dávnejšie aj opačnú skúsenosť s Acer laptopom a baseus powerbank. Ďakujem.
