The powerbank battery of the Romoss brand can be classified in the middle price segment. Inside the not-small (dimensions 180x84x66 mm) and light (1.3 kg) black plastic case “hides” a very capacious 60,000 mAh lithium-polymer battery. Of this, taking into account losses on energy conversion, almost 36 thousand mAh can be given directly to mobile gadgets. This should be enough to charge a modern smartphone about 10 times or a tablet with a large display up to 5 times.
The Romoss PEA60 portable battery provides a large set of 6 ports, including two inputs (Apple Lightning and microUSB), three USB A outputs (two standard at 2.4 A and one with support for fast charging protocols and high current at 4.5 A). The bidirectional USB C connector with Power Delivery 3.0 technology at 18 W also deserves special mention. With one connected device, the output power can reach 22.5 W (which means the charging process will not take much time), and with several connected, the total value drops to 15 W. Among other features of the model, it is worth highlighting the presence of an information display that displays the current charge level of the power bank itself.

A real giant
The Romoss brand offers, so to speak, a hardcore Powerbank for those users who charge their gadgets often and in large quantities. Its capacity is as much as 60,000 mAh, although the real capacity is almost 2 times less - 36,000 mAh. In any case, you can charge your smartphone about 7 – 12 times and use it for a week, or even more, without thinking about the availability of sockets and a power source. When developing such a capacious battery, compactness was sacrificed. When users jokingly call large smartphones bricks, they are mistaken, because a real brick is the Romoss PEA60. This is a large model weighing more than 1300 g, which barely fits in your hand and takes up a lot of space in your bag. If you need a battery that you can take with you on walks, work and school, it is better to choose more compact devices with a capacity of 10,000 or 20,000 mAh. This same giant is more suitable for home use or a long-term lack of electricity: for example, for a summer house where the electricity is constantly cut off, or for hikes that last for a whole week.
Fast charging
Another advantage of the model is the large number of different ports. There are 6 of them: 3 USB A only work as an output, microUSB and Apple Lightning are intended only for charging the power bank itself, and USB type C is a universal port that can charge both the battery and third-party devices. It also supports a maximum power of 22.5 W, while USB A has less power: 18 W for one port and 12 W for the remaining two. The battery supports a large number of fast charging technologies, including both general formats like Quick Charge 3.0 and Power Delivery 3.0, as well as proprietary standards for gadgets from certain manufacturers (Samsung Adaptive Fast Charging, Huawei Fast Charge Protocol and Huawei SuperCharge Protocol). On average, a smartphone charges up to 50% in just 30 minutes, but the exact time still depends on the battery capacity. Also, fast charging has one important nuance - it only works with one device connected. Simply put, the power bank allows you to charge up to 4 devices simultaneously, but in this case you will not get the maximum power of 22.5 W.
With such an impressive capacity, an equally important issue is charging the battery itself. For this, there are 3 ports with the same power - 18 W each. When using the appropriate adapter, full energy recovery will take approximately 14 hours.
There is a small display on the case that displays the following data: current, voltage, remaining power, and charging status. Only one button is responsible for control, and for safety there is a whole system of protection against overcharging, overcurrent, overvoltage, overload and other force majeure situations.
