delivered over <a href="/wiki/USB" title="USB">USB</a>, mainly by communicating to the power supply and negotiating a voltage. </p><p>Quick Charge is supported by devices such as mobile phones which run on Qualcomm <a href="/wiki/System-on-chip" class="mw-redirect" title="System-on-chip">system-on-chip</a> (SoCs), and by some chargers; both device and charger must support QC, otherwise QC charging is not attained. It charges batteries in devices faster than standard USB allows by increasing the output voltage supplied by the USB charger, while adopting techniques to prevent the battery damage caused by uncontrolled fast charging and <a href="/wiki/Buck_converter" title="Buck converter">regulating</a> the incoming voltage internally. Many chargers supporting Quick Charge 2.0 and later are wall adaptors, but it is implemented on some <a href="/wiki/Automobile_auxiliary_power_outlet" title="Automobile auxiliary power outlet">in-car chargers</a>, and some <a href="/wiki/Battery_charger#Power_bank" title="Battery charger">power banks</a> use it to both receive and deliver charge. </p><p>Quick Charge is also used by other manufacturers' proprietary rapid-charging systems. </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Details">Details</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Quick_Charge&action=edit&section=1" title="Edit section: Details"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Quick Charge is a proprietary technology that can charge battery-powered devices, primarily mobile phones, at power levels exceeding the 7.5 <a href="/wiki/Watt" title="Watt">watts</a> (5 <a href="/wiki/Volt" title="Volt">volts</a> at 1.5 <a href="/wiki/Ampere" title="Ampere">amps</a>) supported by the USB BC 1.2 standard, using existing <a href="/wiki/USB#Cabling" title="USB">USB cables</a>.

However, Quick Charge 4 chargers are not backward compatible with Quick Charge.<sup id="cite_ref-7" class="reference"><a href="#cite_note-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup> It also features additional safety measures to protect against over-voltage, over-current and overheating, as well as cable quality detection. Qualcomm claims Quick Charge 4 with Dual Charge++ is up to 5 °C cooler, 20% faster and 30% more efficient than Quick Charge 3.0 with Dual Charge+.<sup id="cite_ref-:5_5-1" class="reference"><a href="#cite_note-:5-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup> </p><p>Quick Charge 4+ was announced on June 1, 2017. It introduces Intelligent Thermal Balancing and Advanced Safety Features to eliminate hot spots and protect against overheating and short-circuit or damage to the USB-C connector. Dual Charge++ is mandatory, while in prior versions Dual Charge was optional. Unlike Quick Charge 4, Quick Charge 4+ is fully backward compatible with Quick Charge C 2.0 and 3.0 devices.<sup id="cite_ref-8" class="reference"><a href="#cite_note-8"><span class="cite-bracket">[</span>8<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-9" class="reference"><a href="#cite_note-9"><span class="cite-bracket">[</span>9<span class="cite-bracket">]</span></a></sup> </p><p>Quick Charge 5 was announced on July 27, 2020.<sup id="cite_ref-10" class="reference"><a href="#cite_note-10"><span class="cite-bracket">[</span>10<span class="cite-bracket">]</span></a></sup> With up to 100<span class="nowrap"> </span>W of power, on a mobile phone with a 4500<span class="nowrap"> </span>mAh battery, Qualcomm claims 50% charge in just 5 minutes.
