MACBOOK USB C CHARGER SERIES
The XPS 15 and Precision 5500 Series models are notable exceptions, since they are designed for 130W, which is actually above the 100W max of the USB PD spec, so Dell did something proprietary on those systems and some of their docks and chargers to run 130W over USB-C. And even if the charger did support a voltage level that the laptop could use, it's likely that the phone charger's maximum wattage output is significantly lower than what the laptop is designed for, so performance will either be severely throttled or the system might simply decide that the power deficit is too significant and therefore won't even try to use it.Īdditionally, current Dell systems seem to have a limitation of only using at most 65W from non-Dell power sources, but relatively few Dell systems that support charging via USB-C require more than that. First of all, phone chargers typically don't support 20V output, which is what most laptops require. However, using a USB-C power source designed for a phone is unlikely to be usable for a laptop. I believe Apple's regular MacBook charger is 60W, which should be pretty good for a Latitude 3590. I have various USB-C chargers made by companies such as Anker, Nekteck, and Satechi, and all of them work fine with my various Dell laptops and other USB-C devices.Īs noted though, if you use a power source whose wattage output is less than the system is designed to use, then you may notice behavior such as slower battery charging and even performance throttling as the system attempts to operate within the reduced power budget. Consequently, as long as the USB-C charger you're using supports USB PD and provides a voltage level that the system will use, you can charge from those chargers. in a public space.Dell systems that support charging via USB-C do so using USB Power Delivery, which is an industry standard. Although this scenario is unlikely to happen by mistake, it would constitute an obvious vulnerability to an exposed device, i.e.
Note: My question asks what happens when two chargers are inserted into a MacBook Pro, but I am also wondering what would happend if 3, or 4 chargers were inserted. I couldn't find anything about this online, but since I am always trying to force a USB in the MagSafe charger of my MacBook Air, I think that I could easily end up making this kind of mistake. Would the computer charge twice as fast, would one of the chargers be dismissed by the system (which one?), or would it generate a surcharge that would destroy the computer? belonging to someone who lives with you and who recently sat at the same spot). This made me think about the following scenario: you sit at a table where your laptop is plugged in on the right, and don't notice that it is plugged in, so you decide to charge it with a second nearby charger that is laying around (i.e.
MACBOOK USB C CHARGER PRO
Apple's controversial decision to convert all the ports on their 2016 MacBook Pro lineup to USB-C ports contributes to blur the difference between ports that supply power (such as a power adapters) and ports that can power external devices (such as USB keys, mice or other gadgets).
