Meet the future of charging and data ports: USB Type-C What Is USB Type-C? What Is USB Type-C? Ah, the USB plug. It is as ubiquitous now as it is notorious for never being able to be plugged in right the first time. Read More (USB-C for short). Over the next few years, USB-C will replace almost all connection standards for both power and data transfer. It’s a near-universal connection standard. But there’s a catch: There’s no universal USB-C charger! Finding the best USB-C chargers can prove difficult, considering a bad USB-C charger or cable can destroy your devices How to Buy a USB-C Cable That Won't Destroy Your Devices How to Buy a USB-C Cable That Won't Destroy Your Devices A few months ago, Amazon banned USB-C cables that did not meet the standards set forth by the USB Implementers Forum (USB-IF), and for good reason: such cables are prone to failure, can damage connected... Read More .

Fortunately, experts like Benson Leung and Nathan-K, and websites like GTrusted, put all the best USB-C chargers and cables in one location. Leung and Nathan-K collaborated on a spreadsheet containing a detailed analysis of a tremendous number of chargers and cables. The spreadsheet can be difficult to read, so I’ve put together a list of their top recommendations along with some buying tips.

USB-C Charger Problems

Before reading further, you need to understand the reasons why Leung and Nathan-K rated some chargers poorly:

  • Shady cables — While some chargers won’t start fires or damage devices, they often ship with cables that can.

Read More separate from the adapter.
  • Quick Charge 3.0 — If a USB-C port can output Quick Charge, it’s out of specification (we refer to this as “out of spec”) and potentially dangerous. However, Leung and Nathan-K don’t regard this as a deal-breaking shortcoming.
  • Legacy D+/D- Encoding — If a charger lacks legacy encoding, it means it can’t use old cables (such as microUSB) even when fitted with adapters.
  • Split PDO or Bad PDO — This means the charger outputs an out-of-specification Power Delivery Object (PDO); it may not charge it its rated speed.
  • IR drop compensation — A lack of an IR drop compensation means the charger doesn’t output a flat voltage at all loads. Excessive voltage drop-offs are known to cause damage to electrical equipment.

In addition to the above points, there are a few other important things that you should be aware of.

Quick Charge 3.0, Turbo, and Auto

Quick Charge 3.0, Turbo, Rapid: Modern battery manufacturers throw additional features onto chargers, such as “Rapid Charging” or “Turbo Charging” (such as Motorola’s USB-C Turbo Charger). Don’t be fooled. The majority of second party charging technologies aren’t proprietary. Both Turbo and Rapid charging are versions of Qualcomm’s Quick Charge specification What's a Quick Charger? Here's Why You Need One Now What's a Quick Charger? Here's Why You Need One Now Smartphones take less time to charge up these days and it's all thanks to a new technology called Quick Charge. If you don't have it yet, you'll want it soon. Read More , which comes built into newer Snapdragon processors. Phones manufactured in 2014 or later likely offer Quick Charge. The standard is reverse-compatible, meaning a Quick Charge 1.0 charger will work with a 3.0 phone and vice-versa. The slowest link in the chain bottlenecks power transfer speeds.

Motorola Turbo Power Charger USB-C

Auto: USB-A ports (the rectangular plugs) on most chargers deliver an “optimized” combination of voltage and amperage. A USB-A port (with auto) automatically senses how fast a device can charge and supplies an optimized amount of power. There’s nothing special about this feature, and despite branding attempts, most implementations function identically to one another. More or less, you can ignore the marketing gimmicks as they relate to USB-A ports.

USB Type-C Power Delivery

USB-C (revision 2) transfers power using a standard called Power Delivery. When you connect a charger to a smartphone, both devices negotiate a power transfer which varies in amperage and voltage. Most chargers can deliver one to six different combinations — multiplying the two together equals wattage. For example, if a charger uses 5 V at 3 amps, it’s pushing 15 watts. If it’s using 15 V at 3 amps, that’s 45 watts to your device.

When picking a charger for a device, you just need to know the maximum voltage and amperage it can use.

The $600 Acer Switch Alpha 12 offers 90% of a Surface Pro, at almost half the cost. Read More that outputs 19 V at 2.37 amps. That equals 45 watts. If you grab a charger from Amazon that maxes out at 5 V and 3 amps, it may not even charge your device. If it does work, it will deliver power at below the maximum wattage, meaning more slowly.

Out-of-Spec Power Delivery

Unfortunately, some of the chargers output out-of-spec (dangerous) power delivery.

USB-C Charging Over PDO

The problems arise when chargers do not comply with the USB-C Power Delivery specification. Shockingly, most chargers on Amazon do not fully comply with the USB-C specification. Here’s a list of the mediocre, bad, and potentially dangerous chargers tested by Leung and Nathan-K:

Bad USB-C Chargers

Out of the 30 devices tested, 16 are poorly designed pieces of junk (a zero means “decline to comment”). Five of these could potentially burn your house down. And while you’d expect similarly poor reviews on Amazon, the opposite is true. Even highly reviewed chargers pose a potential threat to your devices. For example, Aukey’s 60-watt 6-port charger scored a -3 from Leung. Yet its Amazon score strikes gold with a solid 4/5 stars. The reason should terrify buyers: many companies employ fake reviewers to fraudulently boost scores.

FakeSpot, a website specializing in detecting fake Amazon review scores, rates Aukey a D in overall honesty. The actual review score of the charger is around 1.5/5 stars.

What Are the Best USB-C Chargers?

When looking for the best USB-C chargers, there’s one important question: Will the charger work without wrecking your gear? No one should play Russian roulette with their expensive electronics. And with the amount of fragmentation in the USB-C market, even the best chargers may not work properly with all your devices. With that in mind, here are the best USB-C chargers, as reviewed by Leung and Nathan-K.

Google 18W USB-C Power Adapter ($35)

The Google 18W USB-C charger outputs the lowest wattage of the three best-rated chargers. That means it can’t negotiate a high enough output to charge powerful tablets or laptops at max speeds. Overall, it’s a good fit for charging smartphones. Even so, there’s an off-chance that it may trickle-charge a few tablets or laptops. Keep in mind that even Google’s 18W charger won’t charge the Pixel Phone at its advertised 18-watts.

Google 18W USB-C Charger

Verizon USB Type-C Wall Charger ($40)

Verizon’s USB Type-C charger is the best option for those with Quick Charge 3.0 devices. It also includes the latest (and potentially out-of-spec) Quick Charge 3.0 rapid charging capability. What makes this unique among charging solutions is that it’s the only Quick Charge capable adapter to receive praise from Leung and Nathan-K. It also sells in packs of two, so you get double your money’s worth.

Google Universal 22.5W Dual Port Charger ($40)

Regarded by Leung — and many others — as the best travel charger out of the bunch, the “Universal” (it’s not really universal) Google Dual Port charger offers a combination of decent wattage output, two steps of power delivery, and two modular, replaceable USB-C cables. For the price, it’s probably the best charger on the list, although it doesn’t charge a Google Pixel phone at its maximum wattage.

What Are the Second Best USB-C Chargers?

Leung and company ranked a handful of chargers from Anker and dodocool slightly less highly than those from Verizon and Google.

Anker 6-Port USB-C Charger ($40) [UK]

For the money, the best charger is probably the Anker 60-watt USB-C charger — if you don’t need Quick Charge. Not only does the Anker output the correct voltage to power most USB-C laptops, but it also includes a large number of modular ports. You’ll need to, of course, purchase USB-C charging cables (which can cost quite a bit more than USB-A cables).

Anker’s 60-watt charger offers five modular USB-A ports, a single USB-C port, and the full range of voltages necessary to charge most USB-C devices — at their maximum rated charging speed. Unfortunately, despite appearances on paper as a truly universal charging solution, Anker’s charger suffers from a lack of D-/D+ encoding. Without legacy encoding, it can’t use microUSB or Lightning cables with an adapter for USB-C devices.

According to Leung, the 60-watt Anker suffers from a split PDO, meaning its power delivery isn’t within spec. I believe this may be a typo. Otherwise, it should receive a much lower rating.

dodocool 30-Watt USB-C Charger ($19) [CA]

The dodocool 30-watt USB-C charger offers a no-frill 30-watt charging experience for USB-C devices. It features four different power delivery profiles, going all the way up to 20 V and 1.5 amps (which may work for some laptops). Nathan-K believes it to offer great per-dollar value.

On the downside, the dodocool only provides a single USB-C port and its included cable isn’t worth using. On top of that, it lacks legacy encoding, so it doesn’t work with older cables.

What’s the Best USB-C Power Bank?

The Kanex USB-C Power Bank ($100) [UK]

Without question, the best USB-C power bank is the Kanex USB-C power bank. Unfortunately, it runs for almost $100 on Amazon. While it does justify its pricing by offering both USB-A and USB-C charging ports, along with a whopping 15,000mAh which should charge most smartphones at least three or four times. It suffers from a maximum output of 15 watts, which makes it unsuitable for many laptops or higher powered devices.

I should also mention that if you’re a Pokemon Go player Best Pokemon Go Power Bank Best Pokemon Go Power Bank Pokemon Go beats the heck out of a phone's battery.

What the Best USB-C Car Charger?

Belkin Car Charger for USB-C ($40) [UK]

It’s not even close; there’s only a single USB-C car charger that warrants a purchase — the Belkin USB-C car charger. It offers everything that a wall-socket adapter does, including a USB-C and USB-A ports. It also throws in two charging profiles and a maximum wattage output of 27 watts.

Should You Buy a USB-C Charger?

If you’re looking for one of the best USB-C chargers, any one of the top three should meet your needs. If you need the king of all chargers — a feature-rich, universal charger for handling all smartphones, tablets, and laptops, you may need to wait.

As of 2016, few USB-C chargers offer modular cables, Quick Charge, and for all devices on the market. However, if you’re willing to compromise, thanks to Leung and Nathan-K, you now have a few safe options.

    how i find which chargers can function with 220volt 50hz ?
    It does not appear in the spec

      I might be misunderstanding the question. European sockets are 220 volts, IIRC. That's what the draw from the wall, not what they output to devices.

      The output is standardized across devices, so you should be able to use a EU-to-US adapter or vice-versa if traveling without blowing a breaker or frying your device.
