    Xiaomi ZMI 820
    ZMI 10 (QB820) — это безусловно один из самых передовых и технологичных внешних аккумуляторов на рынке. Если вам нужна поддержка USB Power Delivery (для зарядки современных смартфонов, планшетов и ноутбуков), то ничего лучше по функциональности, качеству и цене вы просто не найдёте. Рынок таких зарядных устройств только-только зарождается. Мне даже не к чему придраться. Отмечу ещё раз ключевые особенности этого внешнего аккумулятора:

    Высокое качество изготовления (ZMI / Xiaomi).
    Двунаправленный (DRP) порт USB Type-C с поддержкой USB Power Delivery до 40 Вт официально и до 60 Вт фактически.
    Поддержка Qualcomm Quick Charge 3.0 на входе.
    Поддержка Qualcomm Quick Charge 3.0 на выходе всех трёх портов.
    Одновременное использование всех трёх портов и сквозная зарядка.
    Самая быстрая скорость зарядки самого внешнего аккумулятора среди устройств аналогичной ёмкости.

    muy satisfecho
    Calidad precio yo no he encontrado nada comparable que cargue 45W.
    Tengo un Chuwi surbook Mini , tablet/pc y no encontraba ningún powerbank que me lo cargarse debido a la potencia de carga que demanda el tablet, similar al MacBook. (con Windows 10 y procesador Intel, se chupa los 7000 miliamperios que da gusto) me da para 4 horas de pantalla leyendo más o menos. Este powerbank me lo carga 2 veces justo. Ahora tengo las 4 horas de casa +8 del powerbank + las 6-7 horas que tarda en hacer las 2 cargadas con el powerbank casi al completo=16-19 horas más o menos de pantalla real!!! estoy encantado!!!!
    Ha tardado un mes en llegar aproximadamente.

    Best Power Bank
    The workmanship is excellent. Really working fast charging of built-in batteries is the most important feature. In trips now there are no problems with two devices at once. The complete cable is convenient and practical. The best purchase for trips with a tablet and a phone with long flights. The price on spain sales is very tasty.
    There are two drawbacks: you can not put it on the end, while inspecting the airport, the device draws attention to the introscope. ;-)

    Great PD power bank
    This power bank puts my Moto z play in turbo charge mode. It can be charged very quickly with the Xiaomi 45w type c charger in about 4 hours. The power bank can also be used to power the Nintendo Switch in docked mode and output to an external monitor making it one of the few that can replace the Nswitch power adapter.
    Power bank is quite heavy but is not a massive problem when carried in a bag. The power bank feels like it would scratch easy so I recommend a cloth pouch for it.

    Powerbank idéal pour notebook en usb c
    Très bonne qualité de fabrication ; cela respire la qualité !. Permet de recharger des pc portable notebook en usb c (Xiaomi air 12 ou des macbook Apple) / mais aussi plusieurs appareils en même temps ! Elle fait office de hub usb si besoin (si usb c avec transfert de données actif & fonctionnel). Petit bouton latéral pour avoir le niveau de batterie via 4 petites leds blanches. fourni avec un câble usb c male --> usb c mâle mais aussi un cable usb mâle --> usb c mâle/adaptateur micro usb mâle. Je recommande au vu du prix & des prestations.
    Un peu lourde sur la balance cette batterie ! leds sur le coté très petites & faible en intensité !
