Review: I have several not as good as this - It appears to be just what it says a powerful power bank, I have several not as good as this. Unfortunately I was confused by the power adapter availability. I have a HP Pavilion 360 2 in 1,and the HP adapter which I thought should fit, didn't. It's the exact same spec and color or so I thought but it isn't long enough. There is a vast array of adapters and as I now know the one for my laptop does not come with it. CHECK THE ADAPTERS BEFORE BUYING. Shame, I could have used this for my laptop. Update: The good news is that the company selling this has promised to send me the correct adapter, I'll let you know when I receive it.
Review: Die "PowerOak K2 Notebook und Laptop Power Bank" hält genau was sie verspricht. Die zahlreichen Adapter für die gängigsten Laptop-Anschlüsse bewahren vor dem Kauf eines zusätzlichen Kabels und somit vor Extrakosten. Ich empfehle aber unbedingt vorher zu prüfen, welchen Anschluss Ihr Laptop benötigt, damit Sie keine unangenehme Überraschung erleben! Mit den 50.000 mAh kommt mein Gaming-Laptop für etwa 2,5 Ladungen aus. Damit kann ich dann den ganzen Tag im Büro Videos schneiden und bearbeiten oder am Wochenende auch mal einen Tag bei Freunden durchzocken, ohne eine Steckdose suchen zu müssen. Besonders praktisch finde ich die Power Bank für Zugreisen, da ja bekanntlich die Steckdosen der ICEs nur eine begrentzte Menge liefern und das reicht gerade mal für eine Handyladung. Filme auf der Reise zu schauen oder auch zu arbeiten ist damit überhaupt kein Problem mehr.
