So in summary, the only way to safely use a 15amp device on an outlet that delivers power higher than 15-20A is to somehow inline a 15-20A breaker between the device and the outlet (or, to rewire the outlet and its power feed to 15-20A). It's not really an adapter at that point, but the presence of that 15A/20A fuse provides the missing piece of protection for your 15A/20A device that a plain adapter wouldn't have. There exist fancy "breaker box" adapters that have a 30A plug on one side, a fuse box with a 15A or 20A fuse in the middle, and a 15A outlet on the other side for you to use. Risk of harm increases with outlet power. If you just plug an adapter into it, and your device short circuits, it will explode even more violently.

This is especially relevant when you're considering how to make use of an idle 30A dryer outlet in a garage. The plug used guaranteed it would never receive more than 20amp, and now it's receiving 25!
So if a cheap device correctly assumes as part of its "don't explode" protections that it will never receive more than 20amps due to using a 15-or-20 amp plug, and then it short circuits while plugged into a 25 amp circuit using an adapter, it could very well explode, because the basic guarantees of electrical safety were violated. The electronics that use the 15amp or 20amp plugs are therefore built not only to draw no more than the amps rated by their plugs, but also to self-destruct relatively safely if they draw the maximum amps available from the circuit breaker backing that plug. Most consumer electronics in the US use a 15amp plug, which can be plugged into a 15amp outlet or a 20amp outlet - but no higher, due to physical incompatibilities in the outlet design. The outlet plugs specify the circuit breaker limit. (Electricians, I hope I got this right enough to convey the 'why' I know it won't be perfect.) But for end users, the trend is toward an overall state of reasonable compatibility, with non-working devices quickly acquiring a reputation as such and being shunned out of the marketplace. The main losers here are people trying to do new ground-up implementations, since they can't just work from the standard they also need expensive consultants to tell them the precise subset of the standard is the actual part they can depend on. Didn't HDMI have pretty much this exact issue with EDID and other chaos, until everyone basically agreed that whatever Sony was doing was the right thing and they'd copy them? For a few more years, charger pages will explicit list the products they work with, and eventually it will settle down to a list of must-work-with products for all chargers, and any new products with be tested to ensure that they work in the same ways as one or more of the items on that list of known-working products.

Now, I'm a cheapskate, so most of my electronics are older devices, and as a consequence we still also have various other cables kicking around- Lightning for both our iPhones and wireless earbuds, Micro USB for Kindle and PS4 controllers, even Mini USB for a few random devices.īut as far as USB-C, I would attribute the current mess to growing pains. I don't love that it's like this, but basically the product page just lists every known-to-work device, including Nintendo Switch: I don't actually own a Switch, but my partner and I both charge our laptops (mine a Dell XPS, hers a MacBook) from the same after-market USB-C charging bricks.
