Romoss PEA40PF

The power bank of the Romoss brand debuted on sale at the beginning of 2023 and belongs to capacious solutions (40,000 mAh or 148 Wh) of the initial price category. More than 25 thousand mAh can be transferred to directly connected mobile gadgets, and this is enough for 6-8 recharge cycles up to 100% of most modern smartphones or three full charges of a tablet with a 10-inch screen.

The chips of the model include an increased number of ports. There are two USB A outputs, microUSB inputs (with included adapter) and Apple Lightning (specially for iPhone owners). In addition, the Romoss PEA40PF portable battery also provides USB C, which works "in both directions." The possibility of simultaneously powering three devices is declared, and three connection options are immediately available to feed the power bank itself.

Thanks to support for fast charging standards (for example, Power Delivery 3.0, or Huawei and Samsung proprietary technologies), the maximum output power per device reaches 22.5 W, which is designed to reduce the duration of the charging process. Among other features of the model, it is worth highlighting a large current for USB A (up to 5 A), the presence of an information display and a 10-level protective system.
