The device is powered by a rechargeable battery. A rechargeable battery rechargeable storage of electrical energy on electrochemical basis. A rechargeable battery, storage battery or accumulator is a group of one or more electrochemical cells. They are known as secondary cells because their electrochemical reactions are electrically reversible.
A nickel–metal hydride battery, abbreviated NiMH or Ni–MH, is a type of rechargeable battery. Its chemical reactions are somewhat similar to the largely obsolete nickel–cadmium cell (NiCd). NiMH use positive electrodes of nickel oxyhydroxide (NiOOH), like the NiCd, but the negative electrodes use a hydrogen-absorbing alloy instead of cadmium, being in essence a practical application of nickel–hydrogen battery chemistry. A NiMH battery can have two to three times the capacity of an equivalent size NiCd, and their energy density approaches that of a lithium-ion cell.

Produkt wirkt hochwertig und kommt mit 4 Varta AA-Batterien und einem 1m USBmicro-Ladekabel. Bei der Powerbank handelt es sich um eine neuere Variante, welche ein bisschen anders aussieht wie hier im Angebot.
Was leider weder aus
der Produktbeschreibung bei Digitec noch beim Hersteller klar ersichtlich war: Die Powerbank liefert sehr wenig Strom: Mit AA-Batterien: 5.6V mit 500mA
Hier hätte ich mehr erwartet.
Dies reicht nicht um bei einem Smartphone mit etwas grösserem Bildschirm (in meinem Fall ein Oneplus One mit 5.5") den Akkustand während der Benutzung gleich zu halten. Es reicht jedoch aus um das Gerät über Nacht aufzuladen.
