Select charging capacity
Since capacity is the most important parameter affecting the length of use of mobile power, many people think that the larger the capacity of mobile power, the better, but it is really 20,000 or even 30,000 milliamps.
Is the mobile power bigger and the better? Mobile power of more than 10,000 mAh usually has 5 to 6 batteries. We know that the capacity and volume of the mobile power supply are directly proportional. The larger the capacity, the larger the volume.
Therefore, when purchasing, according to your own needs, if you do not travel frequently, there is no need to carry a "brick" everywhere, and the phenomenon of virtual standards in the market is still very serious, and poor manufacturers use high capacity to blind consumers. The actual capacity of the product is much lower than the marked capacity, so it is not convinced for these ultra-large-capacity mobile power supplies.
With or without boost IC protection
The boost IC from the United States provides an efficient and safe automatic current matching solution. When the load is connected to the fast charge port, the boost IC can immediately detect the acceptable maximum current of the load and then provide the optimal output current for the load. The solution is to protect the battery from excessive current damage by providing a fast charging mode for the load.
Charging treasure compatibility
Choosing a dual output is better than a single output. It is best to be compatible with Phone, Pad, Pod, Psp and most mobile phones.
Mobile phones and other electronic products are diverse, circuit design and interface are not the same, the same mobile power source is not suitable for all electronic products, so you must first understand the interface, voltage and other information required by your electronic products before purchasing. If you can try to bring the counter to the test machine. Generally, the charging voltage and current of the mobile phone is 5V1A. If your mobile phone is special, the interface should be confirmed with the merchant.
The appearance of the charging treasure
There are two aspects here: the first is the appearance of high temperature resistance; the second is the portability of charging treasure.
The appearance is resistant to high temperature performance. The metal casing is superior in fire resistance to the plastic casing. Although the plastic casing used in the brand charging has a certain flame retardancy, it is inferior to the metal casing.
Portability: The first is the weight, weight and capacity proportional: the same material board, the same material (electric core lithium polymer battery and ordinary lithium battery), the same material shell (shell metal and Under plastic conditions, the larger the capacity, the heavier the weight. Under the same conditions, the weight is light but the standard capacity is much higher, and the standard capacity must be false;
The second is the volume: this volume is also proportional to the capacity, the same material of the electric core, under the same condition of the outer casing, the volume is large and the volume is large.
