Description

Adapter

technical field

The utility model relates to an adapter, in particular to an adapter for charging a battery and using the battery to supply power to other electronic devices.

Background technique

Many portable personal electronic devices have become common items in daily life, such as notebook computers, mobile phones, and small multimedia player devices. It is quite common to carry these electronic products out at the same time. However, the most troublesome thing at this time is the power supply, because the manufacturers of these electronic products, especially mobile phones, have their own power supply specifications, special batteries and connector forms, and they must carry various spare special batteries and power cords to continue their use. usage time.

Take the notebook computer as an example. Although the notebook computer has been around for quite some time, its charging method has not changed much. Electrical connection can charge the battery. In other words, the current notebook battery cannot be charged independently of the notebook computer.

Therefore, in order to cooperate with battery charging, it is often necessary to place the entire notebook computer in an unsafe environment (such as on the floor), thereby increasing the probability of accidental damage to the notebook computer. At the same time, since the notebook computer cannot perform the charging operation alone, the battery will also be charged and discharged due to the intermittent power consumption of the notebook computer host, which will reduce the life of the battery itself.

Furthermore, according to the current usage habits of notebook computers, usually after the notebook computer is damaged or replaced, the notebook computer and the battery are discarded together, regardless of whether the function of the battery is good or not. However, no matter what kind of notebook computer batteries store more electric energy than the batteries sold on the market, if the notebook batteries that will be discarded can be used as power supply devices such as power banks or power supplies, it will not only Improve a lot of economic benefits, but also reduce a lot of environmental problems.

In addition, many small electronic products (such as mp3 players or mobile phones) obtain power through universal serial bus (USB) or IEEE 1394 connection ports. In other words, since the connection ports are designed according to international standards, even different electronic products can use the same connection ports or transmission lines to achieve the same purpose. Therefore, aiming at the aforementioned technical characteristics of small electronic products, various portable charging devices have been developed on the market.

Please refer to Fig. 1, it is an existing portable charging device, wherein the battery 7' (or battery pack) is mostly a commercially available AA, AAA rechargeable battery or a special rechargeable battery, and the power output unit 6' is mostly a USB or rechargeable battery. For those who are electrically connected to the mobile phone connector, the charging device can supply power to the mobile phone under the environment without mains power by the setting of the battery pack, and the convenience of portable charging can be achieved only by replacing the battery pack.

For this reason, the battery packs currently available on the market as the charging device all have limited electric energy capacity, and still need multiple sets of batteries as battery backup for power supply to really bring into play the advantages of portable charging.
