Mobile phones, power banks and chargers with fast charging technology have become vastly popular as fast charging tends to be the principal consideration factor when purchasing electronic devices. Among them, power banks certified by Qualcomm's QC 3.0 are widely recognized by consumers.

What is QC 3.0?

QC 3.0 is an abbreviation of Quick Charge 3.0, a fast charging technology researched by American Qualcomm. QC 3.0 is 20% faster than the previous generation 2.0 and reduces power loss up to 45%. QC 3.0 is available in 200mV increments and offers a flexible choice from 3.6V to 20V, while QC 2.0 offers 4V, 9V, 12V, and 20V charging voltages.

QC 3.0 is forward and backward compatible with pre-Quick Charge versions and chargers (including USB Type-C). It has the same ultra-fast charge speed and independent circuit, providing OEM manufacturers with more flexible options. QC 3.0 has a UL certification that helps to meet quality and safety standards, while QC 2.0 does not. So we could see that power banks with QC 3.0 can charge and be charged faster than ever.

How to Charge QC 3.0 Power Bank

A common problem with current QC 3.0 power banks is that you cannot use them to power or charge other devices while the portable charger itself is being charged. Even though some QC 3.o power banks do, there's a short interruption of power when it enters the pass-through charging, causing the devices being charged to reboot and lose data.

Fortunately, there are power banks that support pass though charging, which means it can charge a device while being charged, such as the newest Zendure X6, currently crowd-funding on Indiegogo.

Subversive X6—Charges Devices While Being Charged

Thanks to its UPS mode with pass-through charging, X6 even provides full-power output in pass-through mode and is not limited to the amount of input power provided. This allows you to charge X6 with a solar panel or dynamo while still getting maximum output performance, as long as the solar charger provides a 5V power supply via USB-C. Compact solar chargers aren't the fastest way to charge X6, but if given enough access to direct sunlight, the two will get along quite nicely.

Although X6 has the high 20,000 mAh capacity, it can recharge itself in 3 hours with an industry-leading 45W USB-C PD input, and also it has the most impressive pocket-friendly design——it is the lightest 20,000 mAh PD power bank with only 386g (smallest, too).

Other X6 High-Tech Features

  • X-Charge for low powered devices: Your smart watches, Bluetooth earphones, fitness bands——all the wearable devices that may drop to very low current will be charged smoothly. It is the only USB-C power bank on the market that will not automatically shut off when charging an device with extreme low power.
  • USB Hub: X6 comes with USB Hub mode that provides data transfer functions over its 5 USB ports. When you connect the USB-C Hub port to USB-C port of computers or smartphones, you can charge your device seamlessly.

When recharging your power bank, you can choose to plug charging cable into computer or laptop’s USB interface. However, it’s better to charge with a Quick-Charge-enabled wall charger or adapter. You should check the specific points about it before you charge QC 3.0 Power Bank. Check the manual to make sure the input is compatible to the power bank.

Perfect companion for X6—4-Port adapter with QC 3.0

The Zendure 63W 4-port USB-C PD Charger features 45W USB-C output, three universal travel adapters (US, UK, EU) and supports QC 3.0.

  • 45W output: It could charge your X6 or New MacBook and up to 3 other devices all in one place at the same time. The USB-C output delivers 45W power to recharge your X6 in just 3 hours.
  • 3 plugs: With 3 universal plugs for US, UK and EU, you can enjoy a quick and convenient charge anywhere.

By the way, QC 3.0 and three travel adapters could not be achieved by both Apple 61W USB-C power adapter and Anker 5-Port 30W USB wall charger PowerPort+. That’s why Zendure 63W 4-port USB-C PD Charger could be called the most versatile wall charger for QC 3.0 power bank. And cost-effective, too, it’s only $45.
