Outdated Product
The ultra-light solution weighing only 3.95 kg is designed to provide basic autonomous power during short outdoor trips, picnics, or as a compact backup power source at home. With such a weight and compact size, the station is easy to take even on a long hike where every gram matters. The LiFePO4 battery capacity is 256 Wh with a lifespan of 3000 full cycles, which is sufficient for several charges of laptops or smartphones, operating portable lighting, or a small fan. The 300 W output power covers most low-power devices, with short peak demands up to 600 W supported without issue. One of the interesting features of the Romoss RM300 charging station is the ability to replenish energy through the USB-C port with a 60 W power, in addition to the main built-in power supply of 30...0 W, allowing the device to be charged with compact adapters during trips. A full charge from a household outlet takes only 60 minutes, from solar panels with 100 W power — about 3 hours. On the top panel of the case, there's a wireless charging zone with 15 W power for conveniently charging smartphones without cables. The 230 V socket outputs a pure sine wave, which is important for sensitive electronics. There are also two USB-A ports with fast charging 18 W, one USB-C port with 60 W, and a car cigarette lighter. The uninterruptible power supply function with a switching time of 20 milliseconds protects connected devices during sudden power outages. The built-in flashlight is useful in camping conditions or when working in the dark. The information display shows the current operating parameters of the station.
