Ugreen PB541: a 10,000 mAh power bank with a color screen and Bluetooth monitoring
Ugreen has unveiled the PB541, a 10,000 mAh power bank that does more than just charge your devices — it tells you exactly what's happening inside. The bank launched on China's JD.com at 199 CNY (roughly $28 / £22), making it one of the more feature-packed banks at that price. There's no US or UK listing yet, but if Ugreen follows its usual pattern, a wider release could follow.
The hardware
Two ATL lithium-ion cells sit inside, each rated at 5,000 mAh, for a total of 39.1 Wh — comfortably under the 100 Wh carry-on limit for air travel. Three ports cover most use cases: two USB-C and one USB-A. The built-in USB-C cable doubles as a carrying strap, a practical touch for anyone who regularly leaves cables behind.
The main port delivers up to 45W output, fast enough to charge a flagship phone, a tablet, or a light laptop like a MacBook Air. The bank itself charges at up to 36W. All the major fast-charge standards are supported — Power Delivery, PPS, Quick Charge, AFC, and FCP — so compatibility with Android and iOS devices is broad.
The screen
The side-mounted color TFT display is the PB541's main selling point. It shows battery percentage, live input and output wattage, estimated time to full charge or discharge, temperature, and battery health. For anyone who's ever wondered whether a cable is actually fast-charging their phone, that real-time wattage readout is genuinely useful.
Bluetooth sync with the Ugreen Connect app extends all those stats to your phone. Ugreen claims the ATL cells are rated for 800 charge cycles before significant capacity loss.
Availability and the bigger picture
The PB541 is a China-first release. As of June 2026, neither the US nor UK storefronts list it — Ugreen's current focus in those markets sits on the Nexode and Uno lines. A TechRadar review of Ugreen's 10K magnetic bank found it undercuts Anker on price but raised durability questions. On Trustpilot UK, recent customer complaints mention refund delays of five weeks or more — worth keeping in mind if after-sales support matters as much as the spec sheet.
The PB541 measures 111 × 71 × 18 mm and weighs 227 g — noticeably slimmer than its predecessor, the PB610.
