Power-to-dollar value: We considered the price of the charger relative to the total power it can deliver across its ports, ruling out models that were more expensive but didn’t offer a higher power output or extra features. If you can't choose between the many one or two-port options we've listed and the pricey four-port Anker PowerPort III Slim charger, Baseus has a solution. This 65W wall charger sits comfortably in the middle with three ports, two of which are USB Type-C and the third is USB Type-A. It supports various propriety fast charging technology from Apple, Huawei, and Samsung along with PD 3.0 and QC 3.0 support.

Compatibility—USB C power adapter is compatible with most devices that charge over USB-C including: Apple MacBook and MacBook Pro, Dell XPS, Lenovo Yoga , USB-C Chromebooks, Samsung Galaxy, Google Pixel and Pixel XL plus many more When outputting either its maximum wattage or just below its rated wattage, the Aukey Omnia PA-B5 can get pretty hot, returning skin temperatures of 165 degrees Fahrenheit (73.9 Celsius) and 154 degrees (67.8 Celsius) respectively. However, if it's not pulling close to the maximum -- as laptops rarely do -- the charger will be quite a bit cooler. When we pulled just 65 watts, the Aukey Omnia PA-B5's temperature hit just 119 degrees Fahrenheit, which is in line with what the coolest 65-watt chargers. The life-span of a rechargeable battery depends on many factors including age, temperature history, charging patterns, the chemical composition of the specific battery, and usage. For example batteries stored at 100% charge will degrade faster than batteries stored at 50% charge, this is why most consumer electronics devices arrive from the manufacturer with between 25% to 75% charge. In the end though, it’s what’s inside a cable that matters the most and the Apple USB-C cable has top-notch wiring materials that can deliver the most power to your laptop, phone, or tablet. Want to charge your laptop at 100 watts all day? That shouldn’t be a problem for the Apple USB-C Charge Cable.Get ready for heat: If you're running anywhere close to the rated wattage (or above), expect your USB-C laptop charger to feel toasty to the touch. In our tests, after 20 minutes of running at one watt below their rating (ex: 64 watts on a 65-watt charger), temperatures ranged from 119 degrees Fahrenheit (48.3 Celsius) to 154 degrees (67.8 Celsius). That's unpleasant, but not dangerous. You can get a cooler skin temperature by purchasing a higher capacity charger than you need and running it at less than its maximum. What about a laptop that needs more power, like 135W or higher (which is above the USB-C spec)? If the laptop supports USB-C PD through its USB-C connector despite needing more power than can technically be provided, it will try to charge as fast as the charger can offer. Due to the higher power requirements charging may be slower but still gain battery percentage, or the system will be "treading water", only able maintain a stable battery charge without gaining. In some situations like this, the system when under extreme CPU or GPU load may supplement more power by draining the battery while also drawing power from the charger. This may lead to a slow drain and would eventually run out of power until the load is reduced. In some rare situations like this, the laptop may only be able to gain battery while in sleep mode or off.

All other products will be delivered via the fastest available method (excluding bank holidays and weekends) and generally within 3-5 days, depending on customer location.

AeroWB said:As an electrical engineer this article really makes me cringe. Not because there is a lot wrong with the tests done, and also not the low technical depth. No, the contents are fine but the constant use of the horrible words wattage and amperage are offending and make my brain hurt. Now unfortunately these words have been misused so much that they have become part of the normal vocabulary, that's how languages work. However anyone who knows the proper words would never use those. So I hope you will use the proper words next time, they are power (or rated power) instead of wattage and current instead of amperage.Now you might think, why are those words wrong when they are in the current vocabulary. There are two important reasons: As an electrical engineer this article really makes me cringe. Not because there is a lot wrong with the tests done, and also not the low technical depth.

USB-A ports: We tested how much power each USB-A port can provide. To do this, we plugged in a variable power load and an ammeter, which allowed us to finely control the power flow. We started with the power load set to 0 amps, then turned it up until it matched the promised amperage, ensuring the voltage stayed within 4.75 volts to 5.25 volts. This Maplin 60W USB-C Universal Power Supply Laptop Charger has a reversible USB-C connector that is compatible with popular brands of laptops, tablets, and smartphones. It is suitable for worldwide use, with a universal voltage input of 100-240V AC 50/60Hz. Meanwhile, it delivers a stabilised output at 5V/9V/12V/20V DC 3A. Overload and short circuit protection keep your devices safe. For the curious, here is a fantastically well-written and rigorously illustrated article on this subject, describing the minutiae of a PD implementation bug (in Apple’s own hardware, no less!) that I would recommend to all interested parties.
