Decoding the USB-C Charging Maze

In the exciting world of powerful gaming and multimedia laptops, the battle between USB-C and dedicated power connections rages on. Sure, USB-C might support the fancy-schmancy USB Power Delivery protocol, allowing for charging capacities of up to 100 watts (and even 240 watts in the latest version), but let’s not overlook the trusty dedicated power connection with its higher charging capacity that snugly fits the power supply unit like a glove.

At the heart of charging via USB-C lies the USB Power Delivery standard. Picture this: your smartphone’s power supply unit boasting 30 watts offers power profiles for varying capacities, while your laptop’s power supply unit flaunts an array of power profiles ranging from 45 to 100 watts. Even if the power supply falls short of the device’s demands, fret not! It should still muster up a minimum charging power, albeit at a slower pace.

To fast-track the charging process, both device and power supply must dance to the tune of the optional standard extension PPS. This nifty feature allows the device to request tailored voltage and current from the power supply, resulting in a quicker charge that’s gentle on the battery or adjusts charging power dynamically based on the system’s workload. Keep an eye out for labels like Fast Charge or Super Fast Charge 2.0 on your Samsung gadgets and power supply units – they scream PPS support.

Now, before you dive headfirst into the USB-C PD laptop charger market of 2024 in search of portable powerhouses, remember this golden rule: check for USB Power Delivery support in the technical specs. If your power supply unit or device lacks USB PD mojo despite sporting Type-C, the charging party kicks off at a measly 15 watts. Opt for a power supply cranking out at least 27 watts and a voltage of 9 volts for a smoother charging experience.

Ah, the humble USB-C cable – the unsung hero ensuring a stable flow of charging power from the power supply unit to the device. Not all Type-C connections on the power supply unit play in the same charging power league; one port might deliver a mere 65 watts to your laptop. So, do your due diligence and scour the manufacturer’s website for the nitty-gritty details before swiping that credit card. Keep an eye out for the magic words: USB-C Power Delivery and, if you’re feeling fancy, PPS.

And for those willing to splurge on the crème de la crème, look out for the “GaN” tag on power supply units. This abbreviation heralds the magic of gallium nitride, a semiconductor material that powers up voltage converters with unmatched efficiency and coolness – resulting in pint-sized power supply units packing a serious charging punch. So, whether you’re team USB-C or dedicated power connection, remember: with great power comes great responsibility… and the need for a darn good charger.
