## Customer Reviews

### ⭐⭐⭐⭐ I have several not as good as this
*by A***E on 31 October 2016*

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.
