    The packaging is very good, and the overall size is much smaller than the 20000 milliampere large brick I bought before. It is larger than a mouse and easier to carry. Both ends can be charged, which is very convenient for Apple users

    It’s not very heavy. It feels good. Let’s use it to evaluate it. The express delivery is very fast. The express delivery sent yesterday arrived today. The speed is very fast. I can only say that it is so big. Maybe you don’t believe the capacity. Wait for me to try it and come back to comment.

Charging speed: It is also quite fast, completely saving the dilemma of running out of battery when playing outside

    I am so happy that I finally bought a power bank that can be input-output on both Apple and Android, and the built-in charging cable is also very good. I wish the merchant a prosperous business and a wide source of wealth. The power bank that I would recommend to my friends around me must be Roman Shi.!!

    Size and size: acceptable. Product weight: not particularly heavy. Capacity and size: large. Charging speed: fast. There is a fast charging cable on the iPhone 15, which can be used for airplane charging. It is quite fast and affordable. It can be used multiple times. Logistics can take one or two days to arrive at a very useful power bank????

    I used it several times specifically to evaluate. The first time I bought a 20000 yuan one, it was a bit heavy. Being able to charge multiple phones is indeed much more convenient. I have been asking various questions from the shop owner during this period, and several customer service representatives have a good attitude, concise and easy to understand. I will recommend it to other friends.

    Size: The size is just right. Capacity: 20000 milliampere, rated capacity 12500 milliampere. After buying it, I bought 79% of the electricity to charge the Apple 14pro four times and still have electricity. Product weight: Weight is acceptable, it must be 20000 milliampere. Charging speed: fast, supporting Apple and Huawei fast charging is really good. This is the second repurchase. I bought it myself at the beginning of the month, and now I bought another one for my wife. The one I bought earlier had no reviews, so we are now together
