| Jan 18, 2016 at 8:15 | comment | added | Krzysztof Adamski | @Raphael: This question deserves to be separate question, not a comment as there is no easy answer to it. The shortest one is - you never know, you have to trust the manufacturer. Very often you can buy the same product in different prices and you often get fake products for the price of original one. You can test how well it behaves with proper equipment or if you open it to see how it's built (this requires a lot of knowledge, of course). Opening it up may be the only way to check its quality in terms of long time reliability but it's not easy too. | |

corrected mistake, and made another bit different

There's LAN chip that IIRC can take up to 230mA, there's HDMI, GPIOs etc. And the problem is not about how much current can RPi take but about the voltage that the power adapter can provide at at that load. Most adapters I have seen drops a lot of voltage when they are providing current close to it's max. And it's always good to have some safe margin for power consumption peaks. | |
