Alguns modelos suportam USB Power Delivery e podem tamb\u00e9m suportar protocolos de carregamento r\u00e1pido espec\u00edficos do dispositivo. Com USB PD, aproximadamente 20 W podem ser fornecidos atrav\u00e9s de um perfil como 9 V a cerca de 2,2 A. Um dispositivo limitado a 5 V consumir\u00e1 apenas a energia permitida pela corrente e pelo protocolo de carregamento suportados, e n\u00e3o receber\u00e1 automaticamente 20 W simplesmente porque o carregador \u00e9 classificado para essa pot\u00eancia.

Alguns modelos de 20 W podem ter gabinetes compactos, mas o aumento da temperatura ainda depende da efici\u00eancia de convers\u00e3o, do design do gabinete, da temperatura ambiente e das condi\u00e7\u00f5es de opera\u00e7\u00e3o. Para dispositivos que utilizam PPS ou um modo de carregamento r\u00e1pido espec\u00edfico do fabricante, verifique se o carregador escolhido implementa o modo e a faixa de pot\u00eancia de sa\u00edda necess\u00e1rios. Caso o dispositivo em quest\u00e3o seja um telefone que suporte uma configura\u00e7\u00e3o mais alta, considere se um n\u00edvel de pot\u00eancia maior traria benef\u00edcios adicionais ou se o pr\u00f3prio telefone limita a pot\u00eancia de carregamento.<\/p>\n<!-- 65W Charger -->\n<h3 id=\"section-1-2\" class=\"dc-subsection-title\">Carregador de 65 W<\/h3>\n<p class=\"dc-paragraph\">Um carregador USB-C de 65 W \u00e9 comumente usado para tablets e muitos laptops. Alguns tablets podem consumir entre 20 W e 45 W, enquanto muitos laptops finos e leves t\u00eam pot\u00eancia nominal pr\u00f3xima a 65 W com a tecnologia USB Power Delivery. Um carregador de 65 W normalmente oferece uma variedade de pares de tens\u00e3o e corrente PD, com 20 V a 3,25 A correspondendo a 65 W, e perfis adicionais, como 15 V ou 9 V, para dispositivos de menor pot\u00eancia. A pot\u00eancia fornecida \u00e9 limitada pelo perfil negociado, portanto, um carregador de 65 W tamb\u00e9m pode alimentar um smartphone em um n\u00edvel mais baixo ou suportar um tablet que requer apenas uma fra\u00e7\u00e3o de sua pot\u00eancia m\u00e1xima. Isso faz com que o n\u00edvel de 65 W seja uma escolha comum quando um \u00fanico carregador serve tanto para um laptop quanto para um dispositivo m\u00f3vel em momentos diferentes.<\/p>\n<p class=\"dc-paragraph\">Quando um laptop \u00e9 usado e carregado simultaneamente, parte da pot\u00eancia dispon\u00edvel alimenta o sistema enquanto o restante carrega a bateria. Portanto, \u00e9 importante considerar tanto o consumo de energia do sistema em modo de espera quanto o perfil de entrada compat\u00edvel. Confirme a porta exata \u00e0 qual o laptop est\u00e1 conectado, pois nem todas as portas USB-C de um dispositivo oferecem a mesma capacidade de carregamento r\u00e1pido (PD). Al\u00e9m disso, diferencie a fun\u00e7\u00e3o do carregador da de qualquer hub ou docking station na cadeia de energia. Para um \u00fanico dispositivo principal, um carregador de 65 W \u00e9 adequado para dispositivos com pot\u00eancia nominal de at\u00e9 65 W; para um dispositivo que consome mais energia durante picos de uso, pode ser necess\u00e1rio um carregador com pot\u00eancia superior.<\/p>\n<!-- 100W Charger -->\n<h3 id=\"section-1-3\" class=\"dc-subsection-title\">Carregador de 100 W<\/h3>\n<p class=\"dc-paragraph\">Um carregador USB-C de 100 W \u00e9 geralmente indicado para laptops de alta pot\u00eancia e cargas de trabalho exigentes. Com o USB Power Delivery, a faixa de pot\u00eancia padr\u00e3o suporta at\u00e9 100 W a 20 V\/5 A. Um carregador de 100 W oferece margem para laptops que exigem 65 W ou mais sob carga, al\u00e9m de deixar capacidade para a bateria.

A pot\u00eancia de sa\u00edda cont\u00ednua de um carregador de 100 W sob carga tamb\u00e9m depende do gerenciamento t\u00e9rmico; portanto, a temperatura ambiente e a ventila\u00e7\u00e3o do gabinete devem ser verificadas para opera\u00e7\u00e3o cont\u00ednua. Confirme a pot\u00eancia m\u00e1xima exigida pelo laptop e os perfis PD suportados antes de selecionar um modelo de 100 W e verifique se o cabo atende \u00e0 corrente nominal correspondente \u00e0 configura\u00e7\u00e3o escolhida.<\/p>\n<!-- 140W Charger -->\n<h3 id=\"section-1-4\" class=\"dc-subsection-title\">Carregador de 140 W<\/h3>\n<p class=\"dc-paragraph\">Um carregador USB-C de 140 W \u00e9 geralmente considerado para laptops de alto desempenho selecionados e outros equipamentos compat\u00edveis com EPR (Extended Power Range). A pot\u00eancia de sa\u00edda acima de 100 W se enquadra na faixa de pot\u00eancia estendida do USB Power Delivery (EPR), onde n\u00edveis de tens\u00e3o fixa mais altos est\u00e3o dispon\u00edveis, incluindo 28 V a 5 A para 140 W. A opera\u00e7\u00e3o com EPR requer um carregador compat\u00edvel com EPR, um dispositivo compat\u00edvel com EPR e um cabo USB-C EPR de 5 A com marca\u00e7\u00e3o eletr\u00f4nica. A pot\u00eancia alcan\u00e7\u00e1vel depende da capacidade de cada elemento na cadeia. Um carregador desse n\u00edvel tamb\u00e9m negocia a pot\u00eancia para dispositivos de menor consumo, podendo alimentar um \u00fanico dispositivo profissional e, ao mesmo tempo, manter a capacidade de fornecer uma pot\u00eancia de sa\u00edda maior, caso o dispositivo conectado a suporte.<\/p>\n<p class=\"dc-paragraph\">Como o EPR utiliza tens\u00f5es acima de 20 V e pode fornecer uma pot\u00eancia total maior, as especifica\u00e7\u00f5es do cabo e do conector, o comportamento t\u00e9rmico em opera\u00e7\u00e3o cont\u00ednua e a conformidade com as regulamenta\u00e7\u00f5es do mercado de destino do modelo selecionado devem ser verificados.
