Common charging technologies
Common charging technologies for Bluetooth speakers include wired charging and wireless charging. Wired charging is generally performed through a MicroUSB interface or a Type-C interface, of which the Type-C interface has gradually become mainstream because it supports higher power transmission and faster data transmission speeds. For example, Huawei SoundJoy2 Bluetooth Speaker uses Type-C interface and supports 40W fast charging, which can quickly recharge the speaker in a short time. Wireless charging technology provides users with a more convenient charging method. It realizes power transmission through the principle of electromagnetic induction. For example, Zimi Wireless Charging Bluetooth Speaker supports 20W wireless flash charging. Users only need to place the speaker on the wireless charging base to charge.
Factors affecting charging time
Charging time is affected by many factors. The first is battery capacity. Generally speaking, the larger the battery capacity, the longer the charging time. For example, the battery capacity of OPPO Bluetooth Speaker is 750mAh, and the charging time is about 3 hours. Huawei SoundJoy2 Bluetooth Speaker has a built-in 8800mAh battery, which takes a relatively long time to charge. However, because it supports 40W fast charging, it can also be fully charged in a shorter time. The second is charging power. The greater the power, the faster the charging speed. For example, the Bluetooth Speaker that supports fast charging technology will significantly shorten its charging time. In addition, the use status of the speaker will also affect the charging time. If the speaker is used at the same time while charging, the charging time may be extended.
Charging time of different types of Bluetooth speakers
The charging time of different types of Bluetooth speakers varies greatly. The charging time of small portable Bluetooth speakers is usually shorter, such as the LKERFUN Bluetooth mini cannon, which has a battery capacity of 400mAh and a charging time of about 2 hours. The charging time of medium-sized Bluetooth speakers is generally 3-5 hours, such as the OPPO Bluetooth speaker, which takes 3 hours to charge. The charging time of Bluetooth speakers with large or high-capacity batteries is relatively long. Although Huawei SoundJoy2 Bluetooth Speaker supports 40W fast charging, it takes a certain amount of time to fully charge it. However, it can listen to music for 1 hour after charging for 10 minutes, which can meet the user's short-term use needs.
Charging precautions
In order to ensure the normal charging and service life of the Bluetooth speaker, pay attention to the following points when charging: Try to use the original charger or a charger that meets the specifications to avoid abnormal charging due to mismatched chargers; it is best to turn off the speaker when charging, which is not only good for the battery, but also speeds up the charging speed; when the speaker is fully charged, the charger should be unplugged in time to prevent overcharging from damaging the battery.
