Meanwhile, as one of the most powerful 140-watt adapters on the market, Apple’s brick is very fast and did a great job of recharging the MacBook Pro. However, I must say that it is the only power brick with a single port, which acts as a missed opportunity for the Apple ecosystem. For those who need more flexibility, wireless options are worth considering, although they may not offer the same speed as wired connections.
So for anyone looking for a charger that can charge a decent looking laptop quickly while still having juice to spare, I like it Razer’s 130-watt GaN adapter. It’s the best charger in the range, but also the smallest and most expensive at $180. On top of that, it comes with two international adapters (for UK and EU sales) and a 100-watt USB-C braided cable, both of which you won’t find on others in this category. If you need a reliable power bank or a fast charger on the go, this could be a good investment.
Wrap up
Obviously, there are more than 14 super fast chargers on the market, and sadly I don’t have time to test them all. These days, charging a phone from 100 percent battery to dead can take upwards of 15 hours, so depending on the device, I might try one USB phone charger per day. Just collecting all this data took a good two months. And unfortunately, when I tried this, Anker came out with a new generation of power adapters that I haven’t had a chance to review yet.
That said, there are other things to take. First, to ensure the correct charging speed, you must pay attention to the charging standards of your device and the fast charger; make sure your charger can supply enough power. Manufacturers usually list the device’s charging speed, while power adapters clearly list their USB types and outputs. And when in doubt, you can look for a good quote on the charger right there, even if you have to do the math. Just remember, watts equals volts times amps. In addition, in the case of adapters with multiple ports, you will check to see how the water is distributed when connected to several devices.
Then there are other factors such as size and weight that you may want to consider, with newer gallium nitride (GaN) adapters often featuring compact designs and better power consumption. And if you are in doubt, you can choose a fast recorder made by the same company as your Android phone, iPhone, laptop or other devices, which is especially true for devices such as OnePlus 10T which have fast forwarding protocols.
How we tested fast chargers
The quick ordering process is designed to be as straightforward as possible. I lowered each device to a 10 percent battery, connected the power brick and recorded the amount of charge added every 10 minutes for an hour. Each adapter was plugged directly into a standard 120-volt outlet (without the use of a power cable or additional cables), and if possible I used a cable that is included with the charger or made by the same manufacturer. device. If that was not an option, I used the official 100-watt USB-C cables made by Anker, Apple and others.
Because the charging rates of the devices vary depending on the amount of water you have, I wanted to measure how well each adapter matches the running speed of each device. In most cases, charging is slow between zero and 20 percent before ramping up until the battery hits 80 percent, at which point things slow down again to protect and maintain the health and longevity of the power cell. For a laundry room with multiple ports, I always choose the port that has the most power and doesn’t have multiple devices connected.
As for the devices themselves, I chose Apple iPhone 13, Samsung Galaxy S22 Ultra, Nintendo Switch (launch model from 2017), 2021 Dell XPS 13 and 16-inch M1 Max MacBook Pro. This assortment has been chosen to cover a wide range of models and draw power from 20 watts (iPhone 13) to 140 watts (M1 Max MBP). Also, each system was tested at idle (i.e., no additional programs or games running) to ensure comparable results.
What is important to note is that while the USB Implementers Forum has approved support for USB Power Delivery (USB-PD) charging up to 240 watts, adapters that support power delivery are not available. In addition, although there are a few cables that can handle more than 100 watts of fluid, they are rare or difficult to find.
What is GaN?
When looking at chargers, you may notice that some are labeled GaN, which stands for gallium nitride. This is an important difference because, compared to old adapters that use silicon switches, GaN-based devices support a higher power output and output, which allows manufacturers to create integrated chargers that can cool and support higher watts. Depending on the voltage, GaN chargers can be 30 to 50 percent smaller and lighter than other silicon-based solutions. This may not sound like much, but when it’s in a bag next to your laptop, phone and whatever else you might have, reducing fat and weight can go a long way.
Fast chargers we tested
With a variety of different power output chargers to test, I divided things into three groups. There are 30-watt chargers and below, which are designed for cell phones and other small devices. Then we move on to 45 to 65-watt chargers (give or take a watt or two) that can handle things like phones as well as several thin and light laptops. Finally, we have chargers that put out 100 watts or more, which are good for anything but the largest and most power-hungry laptops. Many of these high-end adapters also have multiple ports, so you can quickly upgrade additional devices. However, because not every power brick supports multi-device charging, I didn’t include it as a test method.
