Battery charger is a very common charging device in our daily life. It can provide convenient charging functions for our mobile phones, tablet computers and other electronic devices. But you know what? There are also several types of battery chargers. Let's take a look together.
The first type: Lithium battery charger
Lithium battery charger is the most common and one of the most popular types of charging treasure. It uses a lithium battery as an energy source, and its capacity is generally around 10,000 mah, which can charge a smartphone about 2 to 3 times. The lithium battery charging treasure is small in size, easy to carry, and suitable for daily use.
So can this portable battery charger that is commonly used in daily life be carried on the plane? Lithium battery battery chargers not exceeding 100wh can be carried on board without declaration; those exceeding 100wh but not exceeding 160wh need to be declared and approved by the airline company; carry-on is prohibited lithium battery electronics and backup batteries exceeding 160wh.
Battery chargers are also not allowed to be used on airplanes. When the plane is in the air and in flight, the pressure is different from that on the ground. In a high-voltage environment, the lithium battery in the battery charger will change, and it is prone to heat and even spontaneous combustion. If you use a battery charger at this time, the probability of spontaneous combustion will increase. If there are flammable and explosive items nearby at this time, the consequences will be disastrous. Therefore, it is strictly forbidden to use battery chargers on the plane.
The second type: Polymer lithium-ion battery battery charger
The polymer lithium-ion battery battery charger is lighter and thinner than the lithium battery battery charger, and the battery life is longer. Its capacity is generally around 5000mah, which can charge the phone 1 or 2 times. But its price is slightly more expensive than lithium battery charging treasure.
Choose polymer batteries, although polymers are safe, have a wide operating temperature range, long cycle life, and are very free to shape, can be made thinner and lighter, have good cycle life and environmental performance, performance, and safety will be better, but the price will be higher. Compared with lithium-ion batteries, polymer lithium-ion batteries have the advantages of less memory effect, more fashion, more personalization, and safer in the eyes of consumers.
The third type: Solar charging treasure
A solar battery charger is a battery charger that uses solar energy as an energy source. It is usually equipped with a solar panel that can automatically recharge when there is sufficient light outdoors. Its capacity is generally small, and it can only charge the mobile phone about 1 or 2 times. But it is very suitable for outdoor activities, travel and other environments.
The fourth type: Wireless battery charger
Wireless battery charger is a new type of battery charger. It does not need to use a charging cable, just put the mobile phone on the wireless battery charger to charge automatically.
Its capacity is generally relatively small, and it can charge the mobile phone about 1 or 2 times. The charging speed of wireless charging treasure is relatively slow, but it is very convenient to use.
Conclusion
The above are the four common types of charging treasures, and each type of charging treasure has its characteristics and uses. When purchasing a battery charger, you can choose the type that suits you according to your needs. At the same time, pay attention to safety when using the battery charger to avoid over-discharge and short-circuit of the battery.
