I use Apple 29w and 87w supplies to charge my Samsung S8+, Moto Z2, Nintendo Switch, MacBookRetina12, my tiny little earbud case, and just the 87w on a Dell Latitude laptop. That’s what the USB-PD spec is all about, which is awesome. Cheap chargers and cables rarely means PD standard-compliant, which is bad, so I urge you to thoroughly research a product before buying.
I believe it’s worth explaining why it’s a good idea to watch out for non-compliant PD chargers and cables.
As far as I know, the USB-C chargers that Apple makes are some of the most USB-PD standards-compliant power supplies out right now. Their Type-C / Thunderbolt cables are very good quality and will reliably communicate between the device (your V, Switch, phone, etc.) and the charger to negotiate proper charging rates. Their price is high but that’s because the chargers and cables are ‘active’, meaning they have little circuit boards on each end which tell the charger and the device how much volts and amps they’re rated for so the supply doesn’t push too much/different rates and the device knows not to request more than the cable or supply can provide.
And that brings us to the bad…
Many chinese manufacturers figure they can save money by selling chargers and cables for cheap that barely meet even one part of the PD and/or Type-C spec. In the best of times they can cause devices to charge at the lowest rate, not to charge at all, or the cables just won’t work for display output or 5/10/20gbps data transfers that they claim to support. In the worst of times they can cause devices to overload their charging circuits, cables to overheat and melt, or cause the charger to try to output more than it’s capable of. We’re talking actual dangerous things happening as a result.
This site is getting old now, but Benson tested a ton of chargers and cables on the market a while ago and the results were demoralizing. I think (someone correct me if I’m wrong) he just posts reviews on amazon product pages these days, so if you see his name on a review, I’d trust it implicitly.
