Ugreen 45W 20K Power Bank Specifications
The power bank uses a 3C + 1A configuration, providing three USB-C connections and one USB-A port. Two of the USB-C connections are built directly into the device, so you do not need to carry separate cords. One is a 13cm cable that functions as a carrying strap and is rated to withstand 10,000 bends.
The other is a retractable USB-C cable made of flame-retardant TPE material that extends up to 70cm across seven length positions. Both built-in cables support up to 45W charging.
On the right side of the silver chassis, there is a standalone USB-C port supporting up to 45W and a USB-A port that outputs up to 22.5W. The device also includes a TFT color display managed by an internal Battery Management System (BMS).
This allows users to view real-time data such as battery temperature, health, charging status, remaining capacity, and cell information directly on the screen, bypassing the need for a smartphone app.
The P7 uses ATL lithium-ion battery cells with a 74Wh capacity at 7.4V, which falls within standard airline travel limits. It supports up to 45W input for recharging. For output, the 45W maximum can charge a 13-inch MacBook Air M5 at up to 43W or a 2026 MacBook Neo at up to 29W.
For smartphones, it charges an iPhone 17 Pro to 69% in 30 minutes at 29W, or an iPhone 17 Pro Max to 65% at 35W. When multiple devices are plugged in at once, the total output drops to a shared 15W.
The device meets China’s 2026 national safety standards for power banks. Ugreen reports it passed durability tests including a 140°C heat chamber for 60 minutes, 2.5 tonnes of pressure, and a puncture test with a 4mm tungsten steel needle.
It includes 20 safety protections for issues like overcharging and abnormal voltage. The power bank measures 136 x 74 x 31mm, weighs 447 grams, and includes a two-year warranty.
