    Very good quality? Has a lot of weight? Not afraid of power outages for a month? Slow power consumption? Long storage time? Too practical

    Roman Shi is definitely an old brand, with excellent quality and reliable battery. It can be fully charged for a week without any problems

    It’s the same one I bought before. I was worried about it being a second-hand product. After receiving the goods, I saw that it was original. This power supply is very easy to use.

    Size: Very suitable, neither big nor small, very good. The product has a large capacity and is very durable. This product is also shipped quickly and is genuine. I have checked and the official certificate shows that it is very new. You can use it now!

    I was on a business trip and wanted to buy a larger capacity. I discovered this model, which has a good appearance and online quality. Currently, it charges quickly and has enough capacity for a week of business trips. The capacity is real and very durable

    When I opened it, I didn’t pay attention to whether it was worn or not. It was too heavy and I returned it for a refund. As a result, the store accepted the receipt as showing signs of wear and tear. They said why they didn’t check it after receiving it. They thought they were unlucky.

    Size: About the same size as a mobile phone, just a little thicker Capacity: OK, it can be charged several times Charging speed of my mobile phone: I tested Apple and it does have about 18w 17.6w. You can check whether the current and voltage are fast charging, which is very convenient

    A single charge of the power bank can charge a mobile phone many times. The logistics speed is very fast. The seller’s service is enthusiastic. That’s why he didn’t ask if he could take it on the train when he took the photo?? 40,000 mAh can’t be taken on the train. You can consult customer service when taking the photo.

    Capacity size: Old brand, not bad. Value for money, perfect product design, and a high-end appearance that is irresistible. The material and workmanship are quite good, and there is no false label on the capacity. The size is just right for me, and the quality of the large factory is trustworthy! The customer service was even more enthusiastic. I was very satisfied with this shopping experience. Product weight: bar charging speed: super fast
