I bought it and used it for a few days. The main body is more compact than I expected, and although it is heavy, I don't feel that much weight, probably because the handle is easy to hold. For the 700Wh class, the rated output is 1,200W in the high output category, and it seems that most home appliances will work. It was a home appliance that consumed a lot of electricity, and the hair dryer and electric kettle had a power of about 1,200W, but they worked stably. In the case of high output, the cooling fan rotates, but it's not an annoying sound that makes you feel loud, so it's acceptable. There was only an Anker USB output, and the USB PD device was charged without any problems. Charging does not require an AC adapter; simply stick the AC cable directly into it, which is convenient. And charging is fast. It is convenient that the output ○○W, battery level, power supply time, and time until charging is completed are displayed in real time. Although the product is generally highly electronically controlled, a sense of stability can be felt in operation. Portable power supplies that have been used until now have a lot of self-discharge, and even if you try to use them due to a sudden power outage, etc., you couldn't use them because they didn't have enough charge. This product seems to be designed to reduce self-discharge, so I'm hoping it can be used even in a sudden power outage. It's a product that has just been released, and I don't have a picture of the back side of the product before I bought it, I didn't search the internet, and I wanted to know it, so I'm attaching a photo of the back side of the product.
