Review on BERKUT JSL-18000 black by Micha Kamierczak ᠌

Without problems, at minus 10 degrees, he started a 2.4-liter gasoline engine with a voltage of 6 volts on the battery. When the battery is disconnected (missing), it is better not to start the engine - most likely you will burn the electronics with an impulse. If the alarm goes off when the device is connected to the car, then you must first turn off the alarm with the key fob and only then start the car. If the charger is discharged, then through the 12 volt power input on the expedition, you can charge from the battery pack or solar panel (12 volts). I consider such devices to be the most necessary thing in a car and the best gift for a car enthusiast!
