Brad Linder<p>The UGREEN Nexode 500W charger can deliver up to 240W of power over a single USB-C port, but it's also a multi-port charger with four more 100W USB-C ports and a USB-A port. All told, it offers up to 500W of power to multiple devices. Coming in March. <a href="https://buff.ly/40mLzf1" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="">buff.ly/40mLzf1</span><span class="invisible"></span></a> <a href="https://fosstodon.org/tags/UGREEN" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>UGREEN</span></a> <a href="https://fosstodon.org/tags/UGREENNexode500W" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>UGREENNexode500W</span></a> <a href="https://fosstodon.org/tags/USBPD" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>USBPD</span></a></p>

Adam Patridge<p>My new favorite tech is devices with USB C ports that don't work/charge when plugged into USB PD ports and only work with a static 5V source.

Fran 🇦🇷<p>But not everything is pure pleasure in the world of USB PD. The USB PD charger I&#39;m using is not a big deal, and has a standby power consumption of 0.125W when it&#39;s working at 5V (unpresentable for 2024 🙈), but when it&#39;s put to work at 20V the standby consumption goes to 1W! 😱. A 5W lamp that consumes 1W when turned off?!?! 💩</p><p>After a couple of days pondering this depressing result, I thought of trying something: Make the charger go back to 5V when the lamp is off!</p><p>🧵 <a href="https://mastodon.online/tags/PortuariaLamp" class="mention hashtag" rel="tag">#<span>PortuariaLamp</span></a> <a href="https://mastodon.online/tags/USB" class="mention hashtag" rel="tag">#<span>USB</span></a> <a href="https://mastodon.online/tags/USBPD" class="mention hashtag" rel="tag">#<span>USBPD</span></a></p>
Fran 🇦🇷<p>The solution? Use the new USB PD chargers, which can deliver different voltages if we ask them nicely 😁. I&#39;m using a board with the HUSB238 to ask the charger to give me 20V, which is enough to turn on the 17V LED and makes everything work more efficient and cooler because the current in the cable is only 0.25A, converting from 220V to 20V is more efficient, and the step-down to regulate the LED current is more efficient than the step-up of the previous version.</p><p>🧵 <a href="https://mastodon.online/tags/PortuariaLamp" class="mention hashtag" rel="tag">#<span>PortuariaLamp</span></a> <a href="https://mastodon.online/tags/USB" class="mention hashtag" rel="tag">#<span>USB</span></a> <a href="https://mastodon.online/tags/USBPD" class="mention hashtag" rel="tag">#<span>USBPD</span></a></p>

ToroidalCore<p>Okay, question for anyone familiar with USB PD. A while ago, I bought a USB car charger on Amazon - basically, it's meant to replace a cigarette lighter in a car, takes 12 V in, and has USB Type A and Type C connectors, and can do 65 watts total - 45 watts on the Type C PD connector. It charges my phone, my Dell XPS laptop, and charges a USB power brick I have. The brick shows voltage and current while charging, and shows 19.2 V and 2.7 A when charging the brick, which tracks with the 45 watt rating.</p><p>I bought a second one of these on Amazon, basically just reordered from the same listing. This one also charges my phone and the power brick, which shows the same voltage and power brick. However, if my laptop is on and I plug it into the new charger, the laptop does not charge. If the laptop is off and I plug it in, the charging light does turn on. I can turn the laptop on and it keeps charging after I boot and log in, but if I unplug the charger and plug it back in, it doesn't charge.</p><p>I exchanged the charger for another one, which behaves the same way. The laptop charges normally with its regular charger. I'm not sure if this is some quirk of USB, or the laptop, or something else I should have looked for when buying these chargers.</p><p><a href="https://hackers.town/tags/USBPD" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>USBPD</span></a></p>
