Offering both the latest QuickCharge 3.0 charging and 18W USB-C PD output, this enormous 20,000mAh power bank will keep your devices charged away from mains power. Great for those times you’re away from a mains outlet! This battery bank can be recharged either through the micro USB input or via the USB C input/output port. The USB C input offers faster recharging, so it's perfect for repeated use when out on the road, in the field with drones and photography equipment etc. You can even use it to charge multiple devices at the same time (although be aware there is a max current output and some devices may not charge without the full output of the battery bank - particularly laptops). Overall size: 136x70x25mm. Includes micro USB charging cable. Note on USB C PD Charging The wattage requirements for device charging varies greatly between devices. Equipment with larger capacity batteries such as laptops, MacBooks etc will charge very slowly with an 18W PD output, especially if the device is being use or in standby mode. Charge latest tablets, smartphones, portable game consoles and more. Dual Quick Charge 3.0 outputs will charge compatible smartphones and tablets 4 times faster.
