This is the do-it-all charger for your laptop, iPhone, and Android

We’re always banging on about wisely future-proofing your tech by buying the best you can afford, with a sensible amount of storage and guaranteed software updates in the future. Because fewer devices are coming with chargers now, it’s time to approach buying a charger for your phone in a similar way, making sure it does everything you want today and also includes versatility for the future.

But charging is surprisingly confusing, especially if you want to fast charge your phone. I’ve been trying the Elecjet X21 GaN Pro fast charger, and it’s an excellent example of what to look for today if you’re shopping for a charger and want to make sure it lasts.

What is the Elecjet X21 GaN Pro charger?

This is a 65W fast charger with true flexibility, providing three USB ports and up to 65W of power, all in a tiny case. The top USB-C port supports USB Power Delivery 3.0 and the elusive PPS format needed for Samsung’s Super Fast Charging at up to 63W. The USB-A port charges using Qualcomm Quick Charge 3.0 and up to 60W, while the central USB-C also supports Power Delivery PPS, but up to 45W. All three can be used at the same time, but speeds will then vary.

If you own an iPhone, a Samsung phone, or any phone that uses Qualcomm Quick Charge technology (including many LG and Motorola phones), the Elecjet X21 should charge it at the fastest speed possible. It will do the same with your iPad, MacBook, and most other tablets and modern laptops too. Although I haven’t tested it, Elecjet says the X21 will fully charge a MacBook in two hours.

It’s a gallium nitride-based (GaN) charger and not a silicon-based charger, meaning it’s smaller, lighter, and more efficient than other, older high-wattage chargers.

Design versatility

The versatility doesn’t stop at the number of ports and high power output. Although I’m not traveling at the moment, that doesn’t mean I won’t be in the future, and the Elecjet X21 GaN Pro will come with me when I do. The charger itself is a small oblong shape with a pair of USB-C ports and a USB-A port on one end and a clever power adapter locking system perfect for travel use on the other.

Included in the box is a U.S. plug, a U.K. plug, and a Euro-style plug, which you simply clip and twist onto the charger, where it’s held securely in place. When I do travel again, there won’t be any messing around with plug adapters or making do with a substandard, slow charging plug. I can just take the requisite adapter and still charge up to three devices at the same time. Thanks to the high power output, the Elecjet X21 will also charge your USB-C laptop, and to help make it possible, the kit comes with an extension lead with a full-size wall plug at the end.

You’d also be forgiven for thinking a 65W charger with room for three USB cables is massive, but it’s not. The GaN technology means fewer components are used inside than in larger silicon-based chargers. The Elecjet X21 Pro is 3 1/4 inches long and a little over an inch wide. It’ll easily slip into a bag.

What about the devices I tested?

The X21 Pro’s big advantage is supporting USB Power Delivery PPS, so it should charge the new Samsung Galaxy S21 range at the fastest speeds possible. I plugged the Galaxy S21 Ultra in, and after 30 minutes it had reached 59%, and was fully charged in about an hour and 20 minutes. Mission accomplished.

My iPhone 12 Pro gained 50% in 28 minutes, but not everything seems to charge very quickly. For example, my iPhone 11 took two hours in total, and my iPhone SE (2020) reached full in an hour and a half. While the charger does not support OnePlus’s proprietary Warp Charge system, it still fast charges and took my OnePlus 9 Pro to full in 85 minutes.

Interestingly, according to the message on the screen of my P40 Pro, it does seem to support Huawei’s Super Charge charging, provided you use Huawei’s proprietary cable. The charger also happily charged a Huawei MateBook X Pro, a notoriously finicky device to power up if you’re not using the included charging block.

Cable problem

Despite the Elecjet X21 Pro meeting most of your charging needs, there’s still a problem: It doesn’t come with any USB cables. While we’ve probably all got a cable or two hanging around, there’s no guarantee they will deliver the fastest charging speeds, especially if they are not USB-C.

Andy Boxall/Digital Trends

I checked with Elecjet to get an idea of what cable someone should buy to make sure everything fast charges now and continues to do so in the future. The team recommended choosing a 100W/5A USB-C cable. If you’re buying a good charger, make sure you buy a good cable to go along with it. After all, this is an exercise in avoiding buying another charger for a while, so don’t cut corners now.

Added to this is some confusion around which port on the charger does what. For example, the top USB-C port is supposed to have the highest output, but it does not activate Super Fast Charging on the Galaxy S21 Ultra. The center USB-C port, however, does. Why? I’ve got no idea, and it was only apparent because I was actively looking at the charging progress. Others may not realize at all. You’ll get used to the way it works with your devices, but definitely check and try the different ports the first time you use it.

Price and availability

The Elecjet X21GaN Pro is available from Amazon for $40, but it’s the version without the travel adapters and desktop extension. The version tested here is available only in the U.K. at the moment, but the company told Digital Trends it will be coming to the U.S. soon. From Amazon in the U.K., it costs 45 pounds sterling, or about $62.

As for the cable, Apple’s official USB-C to Lightning cable is your best bet if you own an iPhone, iPad, or MacBook, as it supports up to 96W power. They start at $19, depending on the length required. For USB-C to USB-C, there are several versions listed on Amazon, such as this $14 version from Aukey and this angled $13 version from UGreen.

What about the future? It should support Samsung and Apple devices in the near term, and if you purchase a phone with a proprietary charging system in the future, it will come with the required charging block and cable anyway. Plus, the power of the Elecjet X21 means it’ll still charge quickly. While there’s no complete way to future-proof your charging tech, the Elecjet X21 GaN Pro is a decent middle ground.

Buy your iPhone charger straight from Apple, warns a new safety study
apple fake chargers unsafe charger lawsuit

Six weeks after Apple launched a lawsuit in connection with fake chargers and other "Apple" items being sold online, tests carried out by global independent safety body UL on such devices have shown 99 percent of them to be unsafe.
Researchers tested 400 fake chargers – sold as made by Apple but found to be phony – and discovered that all but three fell short of basic safety standards, the BBC reported Thursday.
Illinois-based UL found that nearly all of the devices lacked sufficient insulating material to protect against electric shocks. The chargers used in the tests were bought online from eight countries, among them the U.S., China, and Australia.
The chief executive of the U.K.'s Chartered Trading Standards Institute told the BBC that consumers should think seriously about how they buy such items for their smartphones and other gadgets.
"It might cost [a little] more, but counterfeit and second-hand goods are an unknown entity that could cost you your home or even your life, or the life of a loved-one," Leon Livermore said.
With seemingly so many stories in recent months of faulty batteries causing sudden fires and meltdowns, device owners are being warned to take simple steps to stay safe, including never to cover their gadgets when they're charging and never to use a charger that's obviously damaged, such as one with a visibly damaged cable.

Apple lawsuit
Apple's October lawsuit, which targeted Amazon seller Mobile Star, is an attempt by the tech company to stamp out the trade in fake Apple goods.
To support its claim against Mobile Star, the Cupertino company tested more than 100 "Apple" chargers and other products bought from a number of Amazon sellers, and found 90 percent of the devices to be fake.
Apple noted in its lawsuit that "unlike genuine Apple products, they are not subjected to industry-standard consumer safety testing and are poorly constructed with inferior or missing components, flawed design and inadequate electrical insulation."

With offerings ranging from Qualcomm's Quick Charge 3.0 to the Oppo Vooc, the smartphone market is not desperate for quick-charging solutions. Regardless, MediaTek announced the next iteration of its own quick-charging technology, the Pump Express 3.0, that promises to deliver on the promise of "flash charging."

Though it may bring your local gas station to mind, the Pump Express 3.0 comes promises to charge devices from 0 to 70 percent in just 20 minutes, a ludicrously fast charging time that is a boon for people needing a quick top-up before heading out. However, keep in mind that MediaTek did not say what its test setup looks like or the battery capacity of the test device.

iPhone-like 3D Touch feature spotted in Android N
Gionee S8

Evidence that the next version of Google’s Android mobile operating system may include 3D Touch-style app shortcuts has been discovered. References have been found in the code, and the official Preview 2 documentation for Android N, to a feature named dynamic launcher shortcuts, which does sound very similar to Apple’s 3D Touch feature introduced on the iPhone 6S.

The documentation best describes the feature. Designed to help you quickly activate common or popular features inside an app without having to open the app first, shortcut menus will appear after a gesture is made over the app icon on the main Android home screen. Examples given include quickly sending a message using a messaging app, playing the next available episode of a streaming TV show, and choosing a favorite place to navigate to in maps.
