The AstroAI S8 Multifunctional Jump Starter is a portable device designed to jumpstart car batteries, function as a power bank, and serve as an emergency flashlight. It utilizes ultra-powerful discharge technology from a lithium battery to assist in starting vehicles with depleted batteries or in low-temperature environments.
Function Description:
The primary function of the AstroAI S8 is to jumpstart 12V vehicle batteries. It is equipped with smart battery clamps that provide safety features and indicators for correct connection. Beyond jumpstarting, it acts as a power bank with a 5V/2.4A USB output port, allowing users to charge various electronic devices. An integrated LED flashlight offers multiple modes: flashlight, strobe, and SOS, making it a versatile tool for outdoor activities and emergencies.

Usage Features:
- Battery Level Indicator: The device features a battery level indicator with four bars, representing 25%, 50%, 75%, and 100% charge levels. These indicators illuminate circularly during charging and show the current battery level.
- Jumpstarting Process:
- Connection: Fully insert the smart battery clamps into the jump starter. Connect the red clamp to the car battery's positive terminal (+) and the black clamp to the negative terminal (-).
- Indicator Feedback: The smart battery clamps provide visual feedback:
- Illuminated Green: Indicates a correct and safe connection.
- Illuminated Red with Buzz Sounds: Indicates a reversed connection, requiring the user to reconnect the terminals correctly.
- Flashing Green: Indicates low battery voltage. The user must press the "Boost Button" and wait for the indicator to turn solid green before proceeding.
- Initiating Jumpstart: Once the smart battery clamps' indicator is solid green, the user can jumpstart the car.
- Disconnection: After successfully jumpstarting the car, disconnect the smart battery clamps.
- Safety Tips for Jumpstarting:
- Ensure the jump starter's battery level exceeds 75% before starting.
- Remove metal accessories (rings, bracelets, necklaces) before operation.
- Avoid continuous jumpstarting; allow a 30-second interval between attempts to prevent overheating.
- Remove the jump starter from the vehicle's battery within 30 seconds of jumpstarting to prevent damage.
- Do not press the Boost Button before connecting to the car battery.
- Do not connect the red clamp to the black clamp.
- Only use with 12V vehicles.
- Ensure battery terminals are clean and clamps are undamaged.
- Ensure the blue plug on the smart battery clamps is fully inserted into the socket.
- Turn off electrical devices in the vehicle before jumpstarting.
- If the vehicle doesn't start within 5 seconds, remove clamps, wait 60 seconds, and retry.
- If the smart battery clamps' indicator doesn't light up, the battery may be damaged.
- Power Bank Functionality:
- Insert a USB plug into one of the 5V/2.4A output ports.
- Connect the other end of the USB charging cable to the device to be charged.
- Press the Power Button to initiate charging. The jump starter automatically detects device specifications and charges at the proper voltage.
- Illumination Functionality:
- Press and hold the Power Button for 3 seconds to turn on the LED flashlight.
- Press the button again to cycle through Flashlight mode, Strobe mode, SOS mode, and OFF.
Maintenance Features:
- Charging for Optimal Performance: To maximize battery performance and service life, charge the jump starter when its battery level drops below 75%.
- Long-Term Storage: If the jump starter will be idle for an extended period, fully charge it and then recharge it every three months to prolong its service life.
- Disposal: Dispose of the lithium battery according to local guidelines when its service life ends.
- General Care: Do not drop or toss the jump starter. If damaged, have it tested by a qualified battery technician. Avoid storing at temperatures above 70 °C/158 °F. Do not soak in water or expose to rain. Do not modify or disassemble the device; repairs should only be performed by professional technicians.
