According to product sheet of Talema transformer, ta 60 E transformer is 2x1071mA, not like product description here: "USB Max.=2.5A". Transformer has only one secondary circuit connected on the board!! so it is only capable of 1071 mA. That is why the power is not stable and my Raspberry keeps rebooting. Product description is wrong, seller is cheating customers
Only the case with no case came. I just use it because it is troublesome to return it.
