Recently, I found a very interesting battery charger. Maybe somebody will have a question: it just is a common 3.7V battery charger, why do you still remember it? Actually, I bought it just out of curiosity. It's a cylindrical product. And its charging slot is different from a regular battery charger, it's a hive shape. For me, it is the first time to know it. Then, I bought one.




It was not until I went camping that I discovered its advantages. Initially, I took it just as a box for batteries. Because she has six slots for charging 18650, AA, AAA batteries.




When we reached the camp site, we pitched our tent. Gradually, it grew dark. A bunch of people were talking and barbecuing around the campfire. It was a very memorable experience. In the midnight, I wanted to go to a bathroom. But, I just remember one thing. I forgot taking a flashlight and I was unwilling to bothering others. Fortunately, I thought of my new battery charger with a lighting function. Then I took out it. To my surprise, the light is still enough to illuminate the darkness.




The next day, we finished our camping. After that, I found the instruction of the charger and knew its third function. It can be used as a mini power bank with two lithium ion battery.




In addition, the top of the smart battery charger also has an LED panel to display the battery power at any time. Not bad. The entire rechargeable battery charger is smaller than the size of an adult palm.




Overall, the whole experience that gives a person is good. It's worth the price. Cheap and fine.
