The interface chip protection circuit is adopted to effectively monitor the working state of the power supply. Overcurrent automatic protection, the highest 500A current, to meet most of the market's emergency power and cars. It is mainly used for connecting the connection between the emergency power supply and the automobile, and the emergency battery can be started without electricity. Adopting protective circuit, 8AWG copper conductor, the quality is reliable. Reverse -charge Protection - No reverse charging back to the unit after the vehicle started Short-Circuit Protection - Prevent short-circuit occurring while two clamps are connected Over-temperature Protection - Automatically stop working when the temperature is getting too high Reverse Polarity Protection - No damage happened while the clamps are connected in wrong terminals Over-discharge Protection - Effectively prevent over-discharge of the battery in the jump starter Over-charge Protection - Effectively prevent over-charge of the battery in the jump starter Intelligent Detection with LED Indicator to ensures total protection against reverse polarity, surges and short circuits Input/output: 12V; Starting Current:500A Wire Gauge: 8 AWG Strong Alligator Clamp Clip with EC5 Plug Connector (Fit for most car jump portable starters) Suitable for HyperPS QD1, QD3, QD3A, QD5, QD6, QD9 (12V), QD10, QD11, QD12 and all EC5 connector car jump starter, such as compatible with Anker, Brightech, DBpower, eCoreCell, GOOLOO, PowerAll and etc. Specifications: Input Voltage: 12V Starting Current: 500A Operating temperature: -4°C-60°C Wire Gauge: 8 AWG Strong Alligator Clamp with EC5 Plug Connector (Fit for most 12V car jump portable starters) Usage of Car Jump Starter: 1. Plug the cord of jumper cable into the jumper starter's socket. 2. Connect the red battery clamp of jumper cable to the vehicle's positive (+) battery and connect the black to the negative pole. 3. Start the vehicle when jumper cable indicator light turns green.
