I believe the power requirements have actually jumped to 2.5A for the charger (~12.5W).  I&#x27;d be surprised if the Apple 12W charger couldn&#x27;t power one of these without issue for most use cases (2.4A, vs 2.5A reference charger).<p>I can&#x27;t help but notice that the power supply description is incorrect on RS-online&#x27;s site.  They&#x27;re saying 2A in the text, but then their own spec sheet says the power supplies are 2.5A [0]<p>[0] Data sheet: <a href="http:&#x2F;&#x2F;docs-asia.electrocomponents.com&#x2F;webdocs&#x2F;14ba&#x2F;0900766b814ba718.pdf" rel="nofollow">http:&#x2F;&#x2F;docs-asia.electrocomponents.com&#x2F;webdocs&#x2F;14ba&#x2F;0900766b...</a>
