Yep, best thing ever, I bought a GaN charger, 100W 3 USB-C and 1 USB-A. It’s small and light. I carry it around everywhere. I even bring it at my client’s office instead of the power brick they gave me since it’s so small.
Just make sure you have plenty of wattage. For instance, my job laptop uses a 65W adapter. If I want to charge this at the same time as my phone, I would need at least 90W to cover everything (65+25). So I have more power than necessary In order to be able to charge everything at once. Also, make sure to. Heck the adapter on how it distributes power trough the ports. My configuration could not be supported on a 3 port if for example they decided to split the power 55+45. But mine is 65+35 with 2 ports so I’m fine.
I would … after I guy this year’s iPhone … and a new laptop.
Seriously, though, why not? I did get my kid one of the Anker gallium arsenide chargers so he could do exactly that
But I’ll also go the other way - who charges their phone on the lowest power charger? I have a dual charger with total 2.1a, and it fully charges both my phone and watch overnight
I have ACCA installed on my rooted Android phone and have it set to charge at 700mAh, to go easy on the battery. So no matter what charger I use, it always charges slowly lol.
I have a dell laptop. Barrel charging port, but the USB-C port will charge it too... Just very slowly with a 33W phone charger instead of the 130W laptop charger.
I am a usb-pd believer. My phone, laptop, soldering iron, … All usb type-c with usb-pd capability, all running from my laptop charger that can do 5,12,19 and 20v
When all USB could do was 5V I already didn’t trust any charger but mine - I couldn’t believe people dared to connect their devices to charge into any public USB chargers.
Now that they can go up to 20V, and we have to trust everything will work with the negotiation and wiring to get the right voltage, it’s even scarier!
48V and we’re back to POTS (plain old telephone system) voltages :-)
I agree, but that’s the problem even from reputable sources, glitch happens. Old 5V-only chargers would need much more things to go wrong to fry our devices. A 20V (or 48V !) one is just a small (sw or hw) glitch away to zap a device that doesn’t support such voltages.
The USB standard is usally really robust and the changes of SW errors is small. If you have a good brand laptop it will probably come with very reliable charger as well. I really don’t worry about it.
In this thread: people who don’t understand what power is.
Power isn’t something that is “pushed” into a device by a charger. Power is the rate at which a device uses energy. Power is “consumed” by the device, and the wattage rating on the charger is a simply how much it can supply, which is determined by how much current it can handle at its output voltage. A device only draws the power it needs to operate, and this may go up or down depending on what it’s doing, e.g. whether your screen is on or off.
As long as the voltage is correct, you could hook your phone up to a 1000W power supply and it will be absolutely fine. This is why everything’s OK when you plug devices into your gaming PC with a 1000W power supply, or why you can swap out a power-hungry video card for a low-power one, and the power supply won’t fry your PC. All that extra power capability simply goes unused if it isn’t called for.
The “pushing force” that is scaled up or down is voltage. USB chargers advertise their capabilities, or a power delivery protocol is used to negotiate voltages, so the device can choose to draw more current and thus power from the charger, as its sees fit. (If the device tries to draw too much, a poorly-designed charger may fail, and in turn this could expose the device to inappropriate voltages and currents being passed on, damaging both devices. Well designed chargers have protections to prevent this, even in the event of failure. Cheap crappy chargers often don’t.)
