The JENSEN JEP-175 is a portable Bluetooth rechargeable speaker designed for versatile use, featuring a built-in emergency USB charging port, FM radio, flashlight, and a solar charging panel. This multi-functional device is ideal for outdoor activities, emergencies, or everyday listening.
Function Description:
The JEP-175 serves as a portable audio system with multiple input options. Its primary function is a Bluetooth speaker, allowing wireless audio streaming from compatible devices like smartphones, tablets, and computers. It also includes an FM radio tuner for listening to local broadcasts. For wired audio connections, an AUX IN jack is provided, enabling playback from external audio players such as iPods or MP3 players. Additionally, the unit supports USB playback, allowing users to play MP3 files directly from a USB flash drive.
Beyond audio, the JEP-175 integrates practical emergency features. It has a built-in flashlight for illumination, which can be activated by pressing and holding the FLASHLIGHT BUTTON. A significant emergency feature is the USB charging port, which provides a DC 5V, 1A output for charging cell phones and other small portable devices. This is particularly useful in situations where traditional power sources are unavailable.
The device is powered by a 3.7V DC rechargeable lithium battery. It offers two methods for recharging: via a micro USB DC IN jack using a standard 5V DC, 1A output AC adaptor (not included), or through its integrated solar charging panel. The solar panel provides an eco-friendly charging option, especially beneficial when off-grid.
