The WGP Mini UPS is a small battery backup that can keep your internet connection alive during power outages. It works with routers, network devices (ONU), and other small electronics that use 5V, 9V, or 12V power. The built-in battery can last up to 8 hours (depending on the device) and can be recharged and reused over 500 times. It’s lightweight and compact, so it’s easy to place near your router or other equipment.
