It has two USB cables, one for data and one for power. My question is, could I hook up the power USB to a USB phone charger, like this one:<\/p>\n<p><a href=\"https:\/\/web.archive.org\/web\/20160608164756\/http:\/\/www.bestbuy.com\/site\/htc-tc-u250-wall-charger\/2659936.p%3Bjsessionid=C55C82D3E96AEE19134BA1033A059900.bbolsp-app02-145?id=1219075223938&amp;skuId=2659936&amp;st=categoryid$pcmcat171900050026&amp;cp=1&amp;lp=4\" target=\"_blank\" rel=\"nofollow noopener\">http:\/\/www.bestbuy.com\/site\/htc-tc-&#8230;<\/a><\/p>\n<p>The one I have is rated 4.8 V and 1 Amp. This brings up two questions:<\/p>\n<p>1. I thought USB 2.0 could only deliver 500 mA of power&#8230;does it use the data terminals for extra power or something?<\/p>\n<p>2. I don&#8217;t know how much power the drive draws&#8230;that being said, could it really damage the drive trying? I would assume that the drive draws the most power allowed by a USB cable, and a wall adapter shouldn&#8217;t be able to deliver more power than a computer&#8230;right? Or are there no voltage limits on USB cables?<\/p>\n<p>In case you are wondering, I only want to do this so I could open\/close the drive without the computer being on.<\/p>\n<p>Thanks!<\/p>\n","protected":false},"author":5,"featured_media":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"inline_featured_image":false,"iawp_total_views":4},"question-category":[47],"question_tags":[],"class_list":["post-8872","question","type-question","status-publish","hentry","question-category-hardware"],"jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/computing.net\/answers\/wp-json\/wp\/v2\/question\/8872","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/computing.net\/answers\/wp-json\/wp\/v2\/question"}],"about":[{"href":"https:\/\/computing.net\/answers\/wp-json\/wp\/v2\/types\/question"}],"author":[{"embeddable":true,"href":"https:\/\/computing.net\/answers\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/computing.net\/answers\/wp-json\/wp\/v2\/comments?post=8872"}],"wp:attachment":[{"href":"https:\/\/computing.net\/answers\/wp-json\/wp\/v2\/media?parent=8872"}],"wp:term":[{"taxonomy":"question-category","embeddable":true,"href":"https:\/\/computing.net\/answers\/wp-json\/wp\/v2\/question-category?post=8872"},{"taxonomy":"question_tags","embeddable":true,"href":"https:\/\/computing.net\/answers\/wp-json\/wp\/v2\/question_tags?post=8872"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
