Mumbai, May 6: Ugreen has launched its latest 45W power bank, the Rhythm Series S45 (model PB603), now available on JD.com in China for 199 yuan ($29). This power bank boasts a standard capacity of 10,000mAh and aims to solve a common issue: forgetting the charging cable while carrying the battery pack. With a built-in USB-C cable, it provides a convenient solution for charging devices on the go.
Ugreen PB603 Power Bank Specifications
The device measures 152 x 71 x 29.8 mm and features a ripple-textured finish for better grip. A small TFT digital display on the front clearly indicates the remaining battery percentage.
The integrated 45W USB-C cable, located at the top, supports the PD3.0 fast charging standard and has a braided finish for enhanced durability. Ugreen has yet to provide details on additional ports.
Inside, the power bank utilizes ATL battery cells, known for their reliability in the industry. Ugreen claims this model incorporates updated battery technology designed to extend its overall lifespan.
The new model reportedly offers a 166% improvement in charge cycle longevity compared to its predecessor, which was rated for approximately 300 cycles.
For safety, it employs a proprietary Battery Management System (BMS) to monitor charging conditions. The company states that the device has undergone over 150 testing procedures to comply with China’s latest 3C safety standards.
Some tests are particularly rigorous; Ugreen reports that the battery cell passed a puncture test with a 4mm steel needle and withstood 1.43 tons of pressure without igniting or failing. It also survived a heat chamber test at 135°C.
To maintain optimal temperatures during 45W fast charging, the device features a four-layer cooling system. This includes high thermal conductivity graphene materials and an NTC intelligent temperature control system, which performs up to 360,000 temperature checks per hour to prevent overheating.
In related news, OnePlus has recently launched a 15,000mAh power bank with 120W fast charging and advanced battery safety technology.
