Mobile power supplies for mobile phones are also called e-power supplies, easy-to-use batteries, chargers, portable chargers, universal chargers, power banks, etc. The power supply is made of polymer cells as power storage units, which are more powerful than ordinary lithium batteries. The battery is safer and more durable. Its function: it can charge mobile phones, electronic products and digital devices anytime and anywhere or provide standby power. It can be used on the bus, at school, in the police station, in the mountains, in the field, traveling, on business trips, anytime and anywhere. Can charge the electronic products in your hand. Safe and energy-saving, it will not cause any damage to the mobile phone. Speaking of "nicknames", everyone knows it. Think about it, do you have several nicknames in your life? When you are just born, in addition to giving you a formal name, your parents usually give you a nickname such as "Baby". When you grow up and go to school, the baby's nickname will change. It is no longer applicable, so I will give you another more suitable nickname. When you are older, maybe you will also give yourself an English nickname. In short, throughout your life, your nickname will always change and accompany you. But your formal name is used less and less, and sometimes you can’t even remember it! What is a mobile power supply? In fact, it is just like us humans. It has had multiple nicknames accompanying its growth from its birth to the present. Let us count them together! Mobile power banks for mobile phones have had this official name since their birth, and it has been used to this day. Similarly, not long after it was born, many friends gave it the nickname "power bank" in order to protect this newborn "baby". Doesn't this sound very friendly? As the application of mobile phone power supplies becomes more and more widespread, some friends even find that mobile phone power banks can be used as a "warm baby", especially in winter, lying in bed and plugging the mobile power supply into the phone to continue watching blockbusters. When the mobile power supply is used, it will heat up and feel warm when touched with the hands, hence the nickname "Nuanbaobao". However, here, I still want to remind everyone that after all, the mobile power supply is a power supply product. For safety reasons, it is not recommended. Everyone puts it under the quilt and uses it to avoid accidents.
