With 50 Watts of power, the Kanex GoPower USB-C Wall Charger will provide maximum power to maximize your screen time.

We may think that Wireless charging is the way of the future, but USB-C is fast becoming the industry standard for wired charging and data transfer.  Over the past four years, USB-C has continued to impress, providing up to 100W of power, bidirectional power and the ability to quickly transfer data while charging.  It is important to note that USB-C is not the same thing as USB 2.0, 3.0, nor 3.1.  The USB-C is the connector shape, and the technology within the device may be the limiting factor.  USB 3.0 is capable of 5Gbps data transfer, and USB 3.1 is capable of 10Gbps transfers.   Kanex, a trendsetter in products and accessories, strives to win the competition rather than obtaining a participation trophy.  With a total of 50 Watts of power, the GoPower USB-C Wall Charger will allow you to charge a USB-C capable device and a USB-A capable device simultaneously.

Kanex 39 W USB C
The Kanex GoPower USB-C Wall Charger is the stay-at-home version of the recently reviewed GoPower USB-C Car Charger, which is currently powering my tech in my Chevy Silverado.  The product arrived in a 3 15/16 inches wide by 5 1/8 tall by 1 3/8 inches thick retail package.  Like the portable version, Kanex used a pristine white background as a canvas.  Along the middle, you will see a beautiful glossy, raised, photograph-quality image of the Kanex GoPower USB-C wall charger.  Kanex intelligently utilized an inferior reflection/shadow to provide depth and life to their image.  The yellow thought bubble and speedometer served as the image light source, casting shadow underneath and to the left side of the Kanex Charger.  The raised black “KANEX” logo at your bottom right, the black with red accent USB Certified Charger 39W logo at your bottom left, and the title along your top left provided a stark contrast to the background.

As previously detailed, the qualities/features of this product are very similar to the GoPower USB-C Car Charger. Both devices promised to charge your iPhone X or iPhone 8/8 Plus 50% in 30 minutes.  I was skeptical at first about the 27W car charger, but it fully lived up to the promises listed on the packaging. Rotating the packaging ninety degrees clockwise, you can scan the QR code, learn about the limited 1-year warranty and the universal compatibility with any USB powered device.  The opposing face provided the product specifications:  USB-A port 5V 2.4A (12W) output, USB-C 5V/3A, 9V/3A, 15V, 2.6A (39W) output.  The reverse face of the packaging detailed the folding blades of the charger and information about the USB power delivery and fast charge features of the charger.

Kanex GoPower USB C USB A
The 2 15/16 inches long by 2 1/2 inches tall by 1 3/16 inches thick black wall charger weighed a hefty 4.8-ounces.  Along the front of the charger, you will see an upper red 12W USB-A port and a lower 39W USB-C port.  Along the bottom, you will see a subtle dark grey “Certified USB Charger 39W” icon.  The right side of the charger displayed “kanex” in the same dark grey coloration as seen on the front.  I appreciated that kanex was confident enough to leave the left side and bottom of the charger devoid of markings.  Many device manufacturers would have tried to use the available retail space for information, logos, etc., but often less means more.  The back of the dual USB charger had retractable Type A wall prongs, and the top of the device provided information about the AC-DC adaptor, ability to accommodate 100-240V, 50/60Hz frequency, 1.5A input and the 5V/3A, 9V/3A, 12V/2.6A output.  I would have preferred the top/bottom to have been reversed so that the top would have been the sleek bare side that you see.  The Type A prongs were conveniently placed near the top of the charger.  This allowed me to use the lower wall plug and to avoid blocking the upper plug and vice-versa.

To generate the full charging capability with the iPhone X and iPhone 8/8 Plus, you will need to obtain an Apple USB-C to USB-Lightning adaptor.  The cable will allow you to use the full 39W output of the USB-C connection point and to fast charge.  The USB-C car charger took my iPhone X from 7% charge at 5:44 PM to 42% at 6:06 PM, to 60% at 6:21 PM to 76% at 6:36 PM.  To test the more powerful wall charger, I let my phone get down to 10% charge.  Using a DROK USB Type-C LCD Digital Multimeter, I plugged my lighting to USB-C adaptor into the USB-C out and then the USB-C input into the 39W charging port of the Kanex device.  The multimeter read 8.96V/1.89A which was only 16.9Watts of power.  At 11:14 PM my iPhone X was at 10% and by 11:25 it was at 33%.  By 11:37 my iPhone X was at 52% and by 11:44 the phone was at 64%.  The rate of charge was simply amazing.  Without testing it myself, I would not have believed that I would be able to charge more than 50% in 30 minutes.

Kanex Fast Charge
With wall plug real estate at a premium, I do not even consider a charger that accepts less than two devices. I have tested devices that can charge up to 5-7 devices but they may not be able to quickly charge them.  So, one must choose a jack-of-all-trades multi-charger or a specialist-charger that may only charge a few devices.  For travel, I enjoy a multi-charge USB HUB, but for my bedside table, I want a device like the Kanex GoPower USB-C.  The Kanex USB-C 50W device may not have 37 pieces of flare “Office Space” but once you win a gold medal, why would you add a bunch of participation trophies. why do you need more than a Gold Medal?  I would rate the device at 5/5 stars.
