Ugreen PB541 Power Bank Specifications
The power bank is built around two 5,000mAh ATL lithium-ion polymer cells connected in series, resulting in a total capacity of 39.1Wh. For connectivity, it uses a 2C+1A port configuration. The built-in red USB-C cable functions as a carrying strap and provides up to 45W of output, while supporting up to 36W of input to recharge the battery itself.
If you prefer to use separate cables, the device includes a secondary USB-C port with the same 45W output and 36W input limits, along with a USB-A port capped at 22.5W for older devices. It can charge up to three devices simultaneously and supports standard protocols like PD, PPS, QC, AFC, and FCP.
The color screen is positioned on the side of the enclosure. It displays standard metrics such as battery percentage, real-time charging power, estimated charging times, temperature, and battery health. The device also includes Bluetooth connectivity, which allows users to pair it with the Ugreen Smart Life app to upload custom images to the screen.
Internally, the power bank uses Ugreen’s Battery Management System to monitor the lithium cobalt oxide cells. If the system detects temperature or charging abnormalities, it pushes diagnostic alerts directly to the display. The battery is rated for 800 charge cycles, which the company says is an improvement over its older models.
The device measures 111 by 71 by 17.8 mm, weighs 226.4 grams, and uses a standard PC and ABS plastic enclosure. Although it shares most of its core hardware and charging specifications with Ugreen’s earlier 45W power bank (PB610) featuring an angled display, this newer model adopts a different design by relocating the screen and introducing a slimmer overall profile.
