The UGREEN PB312 (25683) 20000mAh 20W Fast Charging Power Bank is a robust and highly efficient portable charging solution designed to keep all your essential devices powered throughout your day. From UGREEN, a leading name in reliable and innovative tech accessories, this power bank combines a substantial 20000mAh capacity with rapid two-way fast charging capabilities, making it an indispensable tool for travel, work, or daily commutes. It’s the perfect answer for anyone who needs to ensure their smartphones, tablets, earbuds, and smartwatches remain charged, no matter where they are. This versatile power bank is available in our Power Banks category at GearBaba.
The core strength of the UGREEN PB312 lies in its impressive 20000mAh battery capacity, providing enough power to charge an iPhone 15 Pro up to 4.5 times or an iPad Pro 11-inch twice. This substantial capacity ensures you stay connected for extended periods without searching for a wall outlet. It features two-way fast charging through its versatile USB-C port, supporting up to 20W Power Delivery (PD) output for rapidly charging your devices (e.g., an iPhone 15 Pro can reach 60% charge in just 30 minutes). Crucially, the USB-C port also supports 20W input, allowing the power bank itself to be recharged in approximately 6 hours with a 20W PD charger, which is significantly faster than standard power banks.
Equipped with a total of three output ports – one USB-C and two USB-A ports – the UGREEN PB312 allows you to charge up to three devices simultaneously. The USB-A ports offer a maximum output of 22.5W, supporting various fast charging protocols like QC3.0, QC2.0, FCP, AFC, and SCP, ensuring wide compatibility and optimized charging speeds for a broad range of Android devices. For devices requiring lower current, it features a low-current mode, perfect for safely charging delicate gadgets like earbuds and smartwatches. A clear smart digital display keeps you informed of the remaining battery capacity at a glance, eliminating guesswork.
