Multi-function Survival Equipment: This wind-up radio is much more than just a portable FM/AM radio for daily use. Behind its well-made exterior is a compact, multi-function device. The radio can be used as a flashlight in the dark, a power bank during power outages, a reading lamp at the campsite, and an SOS alarm with flashlight in emergencies. Ideal for camping, fishing, traveling, and emergency preparedness. 4 Power Supply Options: Equipped with a built-in non-removable 3000mAh rechargeable battery, this hand crank radio offers four charging methods. Micro USB charging is ideal for everyday use. The hand crank and solar panel provide reliable power during outdoor adventures or emergencies. When using 3 x AA batteries (not included), switch to "AA" mode. The radio will remain functional even in critical situations. Note: The internal battery of the radio can be charged via USB, hand crank, or solar panel only. AA batteries cannot be recharged by this device. LED Flashlight & Reading Lamp: This battery-powered radio includes an LED flashlight and a reading lamp, making it a practical tool for outdoor enthusiasts or anyone navigating dark environments. The flashlight illuminates your path and helps prevent tripping during nighttime movement. By unfolding the solar panel cover, the device converts into a convenient reading light for night use. Emergency Power Source: This emergency radio serves as a backup power supply when needed most. If your mobile phone loses power during outdoor activities or a blackout, this device can provide emergency charging to keep your phone running. Note: Always switch to "Li-ion" mode before charging external devices. AA batteries cannot power external devices. SOS Alarm Function: Featuring an SOS alarm, this emergency radio is ideal for outdoor adventures such as camping and hiking. In case of danger or distress, activate the SOS mode. The radio will emit a loud alarm and flashing lights to attract attention and assist in rescue efforts. Two Daily Power Modes: This portable radio supports two standard power modes: "AA" battery mode and "Li-ion" battery mode. When camping or fishing, simply insert 3 x AA batteries (not included) and switch to AA mode to ensure uninterrupted operation. For regular use, charge the internal lithium battery using the included micro USB cable, then switch to Li-ion mode for wireless convenience in the garden, garage, or on the go. Note: Always select the correct power mode before use. Ensure the internal battery is charged when operating in Li-ion mode. Two Emergency Charging Methods: During emergencies such as storms, earthquakes, or power outages, rely on the hand crank or solar panel for charging. Hand Crank Charging: Turn the crank handle to generate power. For optimal charging efficiency, maintain a steady speed until the charging indicator reaches maximum brightness. Note: If the radio is completely discharged, crank for at least 5 minutes before attempting to use it. Solar Panel Charging: Place the solar panel under direct sunlight. When sufficient light is detected, the charging indicator will illuminate, indicating charging has begun. Note: Both hand crank and solar panel charge only the internal lithium battery. They do not charge AA batteries.
