Your USB-C devices deserve a power bank that can provide the proper 3-amp output, but pickin's are slim — even at this stage of the game.
There are a plethora of power banks with Quick Charge 2.0 technology inside, allowing many current smartphones to power-up significantly faster than the norm, but even that's not enough for what's in store for 2016. As devices continue to adopt USB-C as the new standard, the selection of compatible power banks that can push 3 amps is still minimal. We've dug-up a couple available options that will definitely meet your need for USB-C speeds.
RAVPower 20100mAh Battery Pack
Not only does this power bank from RAVPower pack an impressive 20100mAh capacity for its compact size, it also comes loaded with a USB-C input/output as well as support for Qualcomm Quick Charge 2.0 and the newer 3.0 technology. On the front you'll find a Micro-USB input, a USB-C input/output that supports a max of 3 amps, a green-coated Quick Charge 2.0/3.0 output, and a standard 2.4-amp USB output for all other devices.
Since this USB-C power bank comes with multiple options for charging your smartphones and tablets, it also features safe-circuit protection in case of a short-circuit or an overload to protect each connected device. On top of the power bank is a power button next to 4 LED's that indicate how much life remains. Included are two flat-style Micro-USB cables, but unfortunately no USB-C cables. For an excellent portable battery that's capable of rapid-charging your USB-C devices and is also Quick Charge-compatible, the RAVPower is home run.
Anker PowerCore+ 20100
The slimmer option that holds the same 20100mAh capacity is Anker's PowerCore+. This power bank features two USB ports that push a maximum of 6A, providing 2.4 amps per port when connected to non-USB-C devices or 3 amps per port when charging USB-C devices. The PowerPort+ doesn't support any kind of Quick Charge technology, but Anker has still integrated their smart-charging PowerIQ and VoltageBoost technologies to get the fastest charge on each port.
Keeping each connected device safe is a MultiProtect Safety System that features surge protection and short circuit protection. Included with the PowerCore+ is a 24-inch USB-C to USB cable for charging the power bank and a handy travel pouch. Even though this power bank is capable of charging most smartphones and tablets at a reasonable 2.4 amps, it's best-suited for those with USB-C devices that can accept its full potential of 3 amps per port.
