What you need to know about the Elecjet 100W USB-C PD power adapter

• Elecjet 100W USB-C PD power supply: $ 50.99 / £ 42.99

The 100 W charger from Elecjet was developed for charging sophisticated USB-C devices that support the USB Power Delivery charging standard. 100W is enough power to power the most demanding laptops on the market, including Apple’s MacBook range.

With two USB-C ports, each capable of delivering up to 100 W of power, this adapter can charge multiple laptops at the same time. Just note that there are no USB-A ports here. This means that older devices based on third-party standards for fast charging are not supported.

The Elecjet 100W USB-C adapter measures 66 x 66 x 32 mm and weighs approximately 80 g. It is only available in white with US and UK plug variants. However, these plugs are permanently attached and cannot be interchanged. Elecjet does not include a USB-C cable in the scope of delivery.

What is good?

With an output of 100 W and two integrated USB-C ports, the Elecjet 100 W USB-C PD power supply is designed for power-hungry devices and offers excellent energy efficiency. When charging phones, laptops, and even both at the same time, I measured an average of 84.6% wall-to-device power conversion. It’s one of the most efficient chargers out there.

Connected: What is USB Power Delivery and how does it work?

A single smartphone or laptop is supplied with a power of up to 100 W from both USB-C ports via the USB Power Delivery protocol. It’s powered by 3 A at 5 V, 9 V, 12 V, or 15 V, while the 20 V charging option supports up to 5 A of power, although you’ll need a USB-C cable that is also rated for that amount of power.

It can sometimes be difficult to figure out multiple load functions. Fortunately, that’s not the case here. Both USB-C ports drop to a maximum of 45W each when two devices are charged at the same time. This is still enough to quickly charge smartphones, tablets and smaller laptops. Although power balancing that allowed up to 60W on one port would have made this charger a little more ideal for powering a laptop and smartphone at the same time.

What’s not so good?

The Elecjet 100W USB-C PD Power Supply can handle almost any USB-C device you throw at it. The only exception is brand new devices that support the USB PD PPS version of the fast charging standard. The small list of devices that have been using this standard so far includes the latest top smartphones from Samsung Galaxy. These devices are still charging, just not at their top speed.

Second, more power leads to bigger chargers, and while Elecjet’s plug is very compact given the 100W juice packaging, it’s a bit heavy. This isn’t a problem if you intend to keep it plugged in somewhere, but combined with the lack of interchangeable international outlets, this doesn’t make the best travel companion.

Elecjet 100W USB-C PD Power Adapter Review: Should I Buy It?

The Elecjet 100W USB-C PD power supply is a solid charger for smartphones and laptops with USB power supply. However, at $ 50.99, it is on the high end of the market. Therefore, it’s only really worth the money if you need to charge two laptops or other more sophisticated devices at the same time.

100 W of power is excessive for smartphones that are charged via USB Power Delivery. However, if you have two laptops to charge, this is a good choice.

If you are looking for a smartphone charger, you will definitely find cheaper products there. 100 W of power is excessive for smartphones that are charged via USB Power Delivery. The wide range of 30W to 45W USB-C chargers or 60W hubs will save you a few dollars.

If you need USB-A ports for older devices, the Aukey Omnia 100W 4-Port PD Charger falls into a similar price range and offers a more flexible charging configuration. Note that this charger does not support the latest USB PD PPS standard. If you’re looking for something more future-proof, you’ve come to the right place with Elecjet’s own X21 Pro option, as well as Anker’s 65W PowerPort III pod.
