Light, comfortable, not very heated, the charge is slightly less than stated. Good for those who charge the phone at night and want to recharge on the road from work in the evening

The battery came in 8 days (saratov, delivery to the door). Very compact in size, practically does not take up space. My phone-samsung galaxy s9 + up to 100% this battery could not charge. From 13% charges maximum to 75%. The husband's phone is the same situation. In the conditions of the city it is not fundamentally, but the battery was purchased for rest in the mountains (hiking, photos, video phone should be charged). Therefore, we plan to buy the battery more powerful. You can not see how much the battery itself is charged and when it gives off the charge, it warms and whistles (such an obsessive "ultrasound").
