There are two used charging treasures. The first one is a 7500 mAh product win and charging treasure sent by a sister at the university. The work is solid and can be used for a few years. It is not too big. Heavily brought to listen to convenient, but after all, is a product many years ago, plus another disappointing charging treasure. . . Pinsheng Charging Po Small size Only one in and two out Another charging treasure is this cargo Millet mobile power The color took the local tyrant gold pop style 1W mA Slightly bloated volume, still enough storage capacity. It's okay to use it at the beginning. Then it took about a year and a half, and the storage capacity suddenly dropped sharply. Now, it doesn't matter how many times you charge your cell phone, and you can charge up to 20% of the power. So there has always been a thought to buy a charging treasure, originally in Zhang Aunt’s gold exchange there is a millet charging treasure can be exchanged, but found that the same paragraph of my millet charging treasure, then forget it. One day, she opened Aunt suddenly found http:// The price is quite suitable, looked at the comment area and the official website Support fast charge, the volume is also very compact, and light. However, Millet Mobile Power 2 seems to be very similar, which is a disadvantage to me here. Overall, it is still more in line with my expectations. Then place orders~ Out of the box Paper shell packaging is a bit simple Open the wrapping paper shell After tearing is the location of the charging line There is a thin packing jacket There is a seal on the side of the interface and the waist is designed on the side. The arc makes the side look thinner. Right to left is USB interface (output) TYPE C interface (output) MICRO USB interface (input). And battery indicator light. It's about the same size as an Apple 6S. It's about twice as thick, but it's also relatively thin. experience feelings Liberal arts students do not have professional and professional measurement tools to talk about the pros and cons advantage 1, lightweight and compact 177G not really heavy on the hand, and 1W of electricity is sufficient to charge 3-4 times the phone 2, full-featured, intelligent identification, support two-way fast charge. It's more than 4 hours at a time. 3, Yan value is really quite The price of 4,70+ is really expensive under the same quality insufficient 1, white color and easy to dirty, and for the non-slip bump little design more easily blurred. 2, plastic shell is a bit cheap, you can appropriately increase the choice of some different colors.
