It provides a substantial battery reserve and versatile fast-charging options in a compact and travel-friendly design. From the innovative brand Hoco, a leader in high-quality and affordable mobile accessories, this power bank is a key addition to our Power Banks and Chargers & Adapters collections. GearBaba is your trusted source for genuine gadgets, and we are proud to offer this product to help you stay connected and productive.
The heart of the Hoco J136A is a high-density 20000mAh lithium-polymer battery, with a rated capacity of 11000mAh. This is sufficient to provide multiple charges for your smartphone or tablet, making it ideal for a few days of use without needing to find a power outlet. The Hoco J136A power bank supports up to 22.5W fast charging via its two USB-A ports, compatible with protocols like QC3.0, FCP, and SCP, and provides PD20W fast charging through its USB-C port. This is perfect for charging modern iPhones at maximum speed and is also compatible with other PD-enabled devices.
The Hoco J136A offers exceptional versatility with a total of three output ports: a USB-C port and two USB-A ports, allowing you to charge up to three devices simultaneously. The intelligent power distribution system ensures that each connected device receives the optimal current for efficient charging, with a total output of 5V/2A when all ports are in use. The Hoco J136A power bank itself is easy to recharge with its dual input ports—a Micro-USB port and a USB-C port, both supporting up to 18W fast input charging, which significantly reduces the time it takes to recharge the power bank.
The J136A provides a user-friendly experience with its clear LED digital display that shows the exact remaining battery percentage, so you never have to guess when Hoco J136A needs to be recharged. A dedicated green light indicator confirms when fast charging is active. The power bank is built with a flame-retardant ABS+PC shell and multiple layers of advanced safety protection, including overcharge, overcurrent, and short-circuit prevention, ensuring your devices and the power bank itself are safe during use. Despite its powerful features, the unit remains compact and portable, weighing just 425g, making it easy to slip into your bag or pocket.
