USB Power Delivery (PD) changed this in a major way, making power-hungry devices on USB a possibility.<\/p>\n<h2 role=\"heading\" aria-level=\"2\"><span class=\"ez-toc-section\" id=\"Standard_USB_Power_Is_a_Little_Weak\"><\/span>Standard USB Power Is a Little Weak<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Standard USB power specifications don\u2019t offer much in the way of power. There are various USB power standards that devices can call on. Which ones are available depends on what type of USB standard the controller, cable, and device all support. For example, USB 3.2 Gen x2 offers at most 7.5W while USB 3.0 offers 4.5W.<\/p>\n<p>There are special battery charging standards over USB that can pump up to 25W of power into a device and standard USB-C can deliver up to 15W of power, assuming that the charger can provide 3A of current.<\/p>\n<p>Why are USB power standards so limited? The answer is somewhat complicated, but the common denominator here is that all of these standards, even the latest USB-C standard, operate at a mere 5V. Since the total wattage that can be delivered is a product of voltage and current, the only way to give more watts at 5V is to increase current. However, as the Amps go up you\u2019ll run into various issues such as needing thicker wiring and of course, the level of current can quickly become dangerous.<\/p>\n<p>USB Battery Charging (BC) 2 offers the most watts at 5V and 5A, totaling 25W. Fast-charging smartphones, tablets, and modern laptops can easily meet and exceed that number. Quite a few proprietary USB fast-charging methods have been developed to address this, and USB PD exists as a way to accommodate these growing power needs in an industry-standard way.<\/p>\n<h2 role=\"heading\" aria-level=\"2\"><span class=\"ez-toc-section\" id=\"USB_Power_Delivery_Adds_The_Volts\"><\/span>USB Power Delivery Adds The Volts<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The first version of USB Power Delivery running over <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.reviewgeek.com\/53587\/usb-explained-all-the-different-types-and-what-theyre-used-for\/\">Micro-USB<\/a> offered 60W at 3A, which means that it\u2019s also pushing 20V. That\u2019s four times as much as the base-level USB standard. PD 1.0 on USB Type-A\/B\u00a0 upped this to 5A, offering 100W of power.<\/p>\n<p>USB-C Power Delivery comes in two power levels. PD 2.0 and 3.0 over USB-C have the same 100W power rating as PD 1.0 over Type-A\/B connectors. Power Delivery 3.1, however, offers a whopping 240W of power by pushing the voltage up.<\/p>\n<p>USB PD never exceeds 5A of current, but the voltage can be dynamically configured to meet the needs of a device up to the maximum power limit for the standard.<\/p>\n<h2 role=\"heading\" aria-level=\"2\"><span class=\"ez-toc-section\" id=\"The_Device_Handshake\"><\/span>The Device Handshake<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>When a USB PD charger connects to a device, it performs a \u201chandshake\u201d asking the device how much power it needs. USB PD supports seven voltage levels at <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.usb.org\/usb-charger-pd\">5V, 9V, 15V, 20V, 28V, 36V, and 48V.<\/a><\/p>\n<p>In the latest revision of USB PD, a device can ask for an inter<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/social-mediaa\/\" data-internallinksmanager029f6b8e52c=\"1\" title=\"Social Media\" target=\"_blank\" rel=\"noopener\">media<\/a>te voltage starting at 15V. If there are multiple peripherals connected to a USB PD power source, then each device only gets the amount of power it needs. When a device needs more power, it gets it for the duration of that need and then drops back to the lower level of power use.<\/p>\n<h2 role=\"heading\" aria-level=\"2\"><span class=\"ez-toc-section\" id=\"The_Cable_Matters\"><\/span>The Cable Matters<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>While often overlooked, the cable that sits between your device and the USB PD charger is a crucial component. Power can only flow at a rate the cable can handle. The USB PD standard has strict safety limits to prevent cables from overheating with possibly catastrophic results.<\/p>\n<p>In other words, you can only get a particular level of power such as 100W or 240W if the cable you\u2019re using supports it. This will usually be indicated in the cable\u2019s specifications, but in practice, the charger and device will negotiate the fastest power rate that the weakest link in the chain can handle. Whether it\u2019s the charger, cable, or device.<\/p>\n<h2 role=\"heading\" aria-level=\"2\"><span class=\"ez-toc-section\" id=\"Be_Wary_of_Uncertified_Products\"><\/span>Be Wary of Uncertified Products<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<figure style=\"width: 650px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-779143 size-full\" data-pagespeed-lazy-src=\"https:\/\/www.howtogeek.com\/wp-content\/uploads\/2022\/01\/USB-Logos-e1641914771621.png?trim=1,1&amp;bg-color=000&amp;pad=1,1\" alt=\"Certified USB logos\" width=\"650\" height=\"366\" data-crediturl=\"https:\/\/www.businesswire.com\/news\/home\/20210930005098\/en\/USB-IF-Announces-New-Certified-USB-Type-C%C2%AE-Cable-Power-Rating-Logos\" data-credittext=\"USB-IF\" src=\"\/pagespeed_static\/1.JiBnMqyl6S.gif\" onload=\"pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\" onerror=\"this.onerror=null;pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\"\/><figcaption class=\"wp-caption-text\"><span class=\"imagecredit\"><a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.businesswire.com\/news\/home\/20210930005098\/en\/USB-IF-Announces-New-Certified-USB-Type-C%C2%AE-Cable-Power-Rating-Logos\">USB-IF<\/a><\/span><\/figcaption><\/figure>\n<p>In order for a device such as a charger to claim that it\u2019s a USB PD product, it must comply with USB PD specifications.
