Ugreen has launched a new 45W power bank, the Rhythm Series S45 (model PB603), which is currently available on JD.com in China for 199 yuan ($29). This power bank comes with a standard 10,000mAh capacity and is designed to solve a common problem: remembering your battery pack but forgetting the charging cable. By incorporating a built-in USB-C cable, it provides a simple solution for keeping your devices powered while on the move.
Ugreen PB603 Power Bank Specifications
The device has dimensions of 152 x 71 x 29.8 mm. Its exterior features a ripple-textured finish to enhance grip and a small TFT digital display on the front that clearly shows the remaining battery percentage.
The built-in 45W USB-C cable is located at the top of the power bank and supports the PD3.0 fast charging standard. It also has a braided finish to withstand regular wear and tear. Ugreen has not yet provided details about the other ports available on the device.
Inside the casing, the power bank uses ATL battery cells, which are widely recognized for their reliability in the industry. Ugreen highlights that this model includes updated battery technology aimed at increasing its overall lifespan.
The company claims that this new model offers a 166% improvement in charge cycle longevity compared to its previous generation, which was rated for around 300 cycles.
For safety, the power bank employs a proprietary Battery Management System (BMS) to monitor charging conditions. According to Ugreen, the device has undergone over 150 testing procedures to meet China’s latest 3C safety standards.
Some of these tests are quite specific. For example, Ugreen states that the battery cell passed a puncture test using a 4mm steel needle and withstood 1.43 tons of pressure without catching fire or failing. It also reportedly survived a 135°C heat chamber test.
To maintain optimal temperatures during standard 45W fast charging, the device relies on a four-layer cooling system. This includes high thermal conductivity graphene materials and an NTC intelligent temperature control system that Ugreen says performs up to 360,000 temperature checks per hour to prevent overheating.
In related news, OnePlus has recently introduced a 15,000mAh power bank with 120W fast charging and advanced battery safety technology.
