I've used the best multi-charging device. It's EGO EXINNO that even measures 240W real-time power. During this EGO EXINNO review, we would like to learn about the actual performance and usability of this product. It is a portable high-performance multi-charging device, but it is not insufficient to use at home or in the office. It is a product that can charge two laptops at 100W 100W at the same time and charge other devices quickly while charging them at 200W. There are many products that have been reduced in size using GaN (Gallium nitride) these days. It is the most expensive product among those products. If you want to use a small, high-performance multi-charging device, try buying this product.
