Which protocol runs cooler?<\/h2>\r\n\r\n    <p class=\"dc-paragraph\">\r\n        Heat is the end-user question and the B2B question at the same time. Less heat means longer component life and fewer returns.\r\n    <\/p>\r\n    <p class=\"dc-paragraph\">\r\n        <strong>For heat inside a phone, PPS wins. For stability and system-level efficiency at high power, AVS wins.<\/strong> The trade-off is real and it maps onto two different product categories.\r\n    <\/p>\r\n    <p class=\"dc-paragraph\">\r\n        Efficiency here means keeping the difference between supply voltage and required voltage small. The loss is roughly (supply voltage \u2212 required voltage) \u00d7 current, so every tenth of a volt that does not need converting is heat that never happens.\r\n    <\/p>\r\n\r\n    <!-- 4.1 PPS and battery heat -->\r\n    <h3 class=\"dc-subsection-title\" id=\"section-4-1\">4.1 PPS and battery heat<\/h3>\r\n\r\n    <ul class=\"dc-reading-list\">\r\n        <li><strong>Minimal mismatch.<\/strong> 20mV steps mean the adapter can sit within a few hundredths of a volt of what the cell needs.<\/li>\r\n        <li><strong>Heat moves outward.<\/strong> Whatever conversion remains happens in the adapter, which has more surface area and better airflow than a sealed handset. This is why a PPS adapter often feels warmer than the phone during a fast charge \u2014 that is the design working.<\/li>\r\n        <li><strong>Limitation.<\/strong> The gain applies to the battery path only. PPS says nothing about efficiency on a laptop's main rail.<\/li>\r\n    <\/ul>\r\n\r\n    <!-- 4.2 AVS and system heat -->\r\n    <h3 class=\"dc-subsection-title\" id=\"section-4-2\">4.2 AVS and system heat<\/h3>\r\n\r\n    <ul class=\"dc-reading-list\">\r\n        <li><strong>Rail-level matching.<\/strong> The device reports the voltage its internal converters want, and the adapter supplies it, so those converters work less.<\/li>\r\n        <li><strong>Relevant at high power.<\/strong> At 48V\/5A, a 0.5V mismatch is 2.5W of loss; AVS's whole purpose is to keep that mismatch small across a wide band.<\/li>\r\n        <li><strong>Limitation.<\/strong> 100mV steps are too coarse to track a single cell, so AVS is not a substitute for PPS in a phone.<\/li>\r\n    <\/ul>\r\n\r\n    <!-- ============================================================\r\n         5.

Where is this heading?<\/h2>\r\n\r\n    <p class=\"dc-paragraph\">\r\n        The direction is convergence under one umbrella, not replacement of one protocol by another.\r\n    <\/p>\r\n    <p class=\"dc-paragraph\">\r\n        <strong>AVS is becoming the baseline for high-power sources because compliance requires it; PPS stays optional and remains the thing premium phone charging is built on.<\/strong> In practice, a good adapter in two years will list PD as the foundation, AVS for system power, and PPS for handsets.\r\n    <\/p>\r\n    <p class=\"dc-paragraph\">\r\n        Beyond the standards themselves, adapters are starting to combine protocol negotiation with temperature and battery-state sensing, adjusting the supply within the legal step size rather than only at the start of a charge. That direction makes both PPS and AVS more useful, not less.\r\n    <\/p>\r\n\r\n    <!-- ============================================================\r\n         7. Conclusion\r\n         ============================================================ -->\r\n    <h2 class=\"dc-section-title\" id=\"section-7\">7. Conclusion<\/h2>\r\n\r\n    <p class=\"dc-paragraph\">The three acronyms answer three different questions:<\/p>\r\n    <ul class=\"dc-reading-list\">\r\n        <li><strong>PD<\/strong> \u2014 can this charger power this device at all?<\/li>\r\n        <li><strong>PPS<\/strong> \u2014 can it charge this phone's battery quickly without cooking it?<\/li>\r\n        <li><strong>AVS<\/strong> \u2014 can it hold a stable, efficient rail for this laptop or high-power system?<\/li>\r\n    <\/ul>\r\n    <p class=\"dc-paragraph\">\r\n        Design for the device you are shipping. A phone charger without PPS is leaving fast charging on the table; a 140W laptop adapter without AVS is out of step with PD 3.1 and 3.2.\r\n    <\/p>\r\n\r\n    <!-- ============================================================\r\n         8. FAQ\r\n         ============================================================ -->\r\n    <h2 class=\"dc-section-title\" id=\"section-8\">8. FAQ<\/h2>\r\n\r\n    <p class=\"dc-paragraph\"><strong>1. Is AVS faster than PD or PPS?<\/strong><\/p>\r\n    <p class=\"dc-paragraph\">\r\n        No \u2014 step size does not set speed. AVS's 100mV resolution is coarser than PPS's 20mV. AVS improves <em>system<\/em> efficiency at high power, which can translate into more sustained power before thermal throttling, but calling it a faster protocol is a misreading of what it does.\r\n    <\/p>\r\n\r\n    <p class=\"dc-paragraph\"><strong>2. Can a PD charger charge a device that supports AVS?<\/strong><\/p>\r\n    <p class=\"dc-paragraph\">\r\n        Yes. The pair negotiates down to a fixed PDO and charging continues normally. You lose the fine voltage matching, so the device may run warmer or throttle earlier, but nothing breaks.\r\n    <\/p>\r\n\r\n    <p class=\"dc-paragraph\"><strong>3. Which devices actually use AVS today?<\/strong><\/p>\r\n    <p class=\"dc-paragraph\">\r\n        Mainly high-power laptops, docks and the larger Apple power adapters, plus a growing number of 140W-class bricks that need EPR. AVS support in phones is rare, because PPS already does the job at that power level.\r\n    <\/p>\r\n\r\n    <p class=\"dc-paragraph\"><strong>4. Does PPS still matter now that AVS exists?<\/strong><\/p>\r\n    <p class=\"dc-paragraph\">\r\n        Yes. They cover different power ranges. PPS handles 3.3\u201321V at up to 5A for batteries; AVS handles 9\u201348V for system rails. A 100W-class laptop adapter has little reason to implement PPS, and a phone charger has no need for EPR AVS \u2014 though some multi-port adapters do carry both to serve a mixed load.\r\n    <\/p>\r\n\r\n    <p class=\"dc-paragraph\"><strong>5. How can I tell which protocols a charger supports?<\/strong><\/p>\r\n    <p class=\"dc-paragraph\">\r\n        Read the PDO list rather than the marketing text. A PPS-capable source shows a PPS APDO with its voltage range and current limit; an EPR AVS source shows the 15\u201348V AVS ranges. If a listing only says \"PD 3.0 fast charging\" without ranges, assume fixed PDOs only.\r\n    <\/p>\r\n\r\n    <!-- ===== \u5e95\u90e8\u7edf\u4e00\u5185\u94fe\u6a21\u5757 ===== -->\r\n    <div class=\"dc-related-cta\">\r\n\r\n        <div class=\"dc-cta-block\">\r\n            <h2>Explore Related Charging Products<\/h2>\r\n            <p>Explore WJW's USB charging solutions and USB-C cable options for different charging protocols and fast-charging applications.<\/p>\r\n            <ul>\r\n                <li><a href=\"https:\/\/www.wjwsy.com\/usb-chargers\/\" target=\"_blank\" rel=\"noopener\">Explora los cargadores USB<\/a><\/li>\r\n                <li><a href=\"https:\/\/www.wjwsy.com\/category\/usb-type-c-cable\/\" target=\"_blank\" rel=\"noopener\">Explore USB Type-C Cables<\/a><\/li>\r\n                <li><a href=\"https:\/\/www.wjwsy.com\/usb-cables\/\" target=\"_blank\" rel=\"noopener\">Explorar cables USB<\/a><\/li>\r\n            <\/ul>\r\n        <\/div>\r\n\r\n        <div class=\"dc-cta-block\">\r\n            <h2>Have a Custom Charging Project?<\/h2>\r\n            <p>Contact our team to discuss your charger and cable specifications, customization requirements, and OEM\/ODM projects.<\/p>\r\n            <ul>\r\n                <li><a href=\"https:\/\/www.wjwsy.com\/contact-us\/\" target=\"_blank\" rel=\"noopener\">Contact WJW<\/a><\/li>\r\n            <\/ul>\r\n        <\/div>\r\n\r\n    <\/div>\r\n\r\n<\/div>\r\n<!-- end .dc-guide -->\r\n\r\n<!-- ============================================================\r\n     \u5e73\u6ed1\u6eda\u52a8 JavaScript\uff08\u4e3a\u6240\u6709\u76ee\u5f55\u951a\u70b9\u94fe\u63a5\u6dfb\u52a0\u5e73\u6ed1\u884c\u4e3a\uff09\r\n     ============================================================ -->\r\n<script>\r\n    (function() {\r\n        if (document.readyState === 'loading') {\r\n            document.addEventListener('DOMContentLoaded', initSmoothScroll);\r\n        } else {\r\n            initSmoothScroll();\r\n        }\r\n\r\n        function initSmoothScroll() {\r\n            var tocLinks = document.querySelectorAll('.dc-toc-list a');\r\n            tocLinks.forEach(function(link) {\r\n                link.addEventListener('click', function(e) {\r\n                    var href = this.getAttribute('href');\r\n                    if (href && href.startsWith('#')) {\r\n                        var targetId = href.substring(1);\r\n                        var targetElement = document.getElementById(targetId);\r\n                        if (targetElement) {\r\n                            e.preventDefault();\r\n                            targetElement.scrollIntoView({\r\n                                behavior: 'smooth',\r\n                                block: 'start'\r\n                            });\r\n                        }\r\n                    }\r\n                });\r\n            });\r\n        }\r\n    })();\r\n<\/script>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"<p>TECHNICAL COMPARISON &nbsp;\u00b7&nbsp; USB-C CHARGING PROTOCOLS AVS vs PD vs PPS: What Are the Differences?
