Electric current is a flow of electric charge through a medium. This charge is typically carried by moving electrons in a conductor such as wire. The SI unit for measuring the rate of flow of electric charge is the ampere, which is charge flowing through some surface at the rate of one coulomb per second.
There are two types of batteries: primary batteries (disposable batteries), which are designed to be used once and discarded when they are exhausted, and secondary batteries (rechargeable batteries), which are designed to be recharged and used multiple times. Miniature cells are used to power devices such as hearing aids and wristwatches; larger batteries provide standby power for telephone exchanges or computer data centers.

Li-ion
A lithium-ion battery (sometimes Li-ion battery or LIB) is a member of a family of rechargeable battery types in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging. Li-ion batteries use an intercalated lithium compound as the electrode material, compared to the metallic lithium used in non-rechargeable lithium battery.

Edition 16/2016
- Die Varta Indestructible Powerpack 6000 ist mit einem Preis von rund 35 Euro die teuerste Powerbank im Vergleich, ist diesen jedoch durchaus Wert. Dies liegt nicht zuletzt an einem hochwertigen Gehäuse, dieses wirkt sehr gut verarbeitet. Die Gummischicht ist für den Schutz von Ecken und Seiten sinnvoll, bei Stürzen wird kaum ein Kratzer hinterlassen. Auch kurze Tauchgänge sind mit diesem Modell kein Problem. Weiterhin ist die Leistung in Ordnung und die Ausstattung kann sich durchaus sehen lassen.
