Features

• The product’s input is a vehicular DC cigarette lighter joint and the output is two American Standard AC sockets.
• This product converts DC12V to AC 115V/60HZ modified sine wave output after transformer boost.
• This product transforms DC12V into 5V/4.8A USB output. USB with intelligent identification chip 0-2.4A can automatically identify and match the charging current of your equipment so that the charging speed can be faster. What s more, the smart-USB drive circuit with stabilizing technology always maintains a fast charging status when charging.
• This product has overload, over-current and short-circuit protection, which fully protects your electrical appliances.

Overload Protection Point

• The input voltage is 12V. It begins to protect when the AC output is over 580W or when being loaded time of 500W-550W is more than 20 seconds.
• USB output is 5V/4.8A; Overload protection occurs when the USB output current is more than 5-6A. After overload protection, the product will automatically restore 5 times. After five times, if there is still an overload, the system will detect the fault and make locking protection.( The protection point is in a critical state and does not lock. the product always try to start your electrical device.)

Short-circuit Protection Point
Twice is allowed(The time of short-circuiting is more than 1 second every time) and then get into the locking status and the red light is always on. If you want to use it. When you turn off the power, you should wait for the red light to turn off before restarting. The green light is always on when working normally.

Under-voltage Protection Point
Under-voltage protection comes with a restoration function, in which the under-voltage protection point is 10V-11V when it’s in no-load condition, and the monitoring time is more than 0.5 seconds. The recovery voltage is 11-12V. Starting up the host at an under-voltage point, the system defaults the voltage of the battery as too low to start up and makes it under lock status, not allows to start up. At the same time, the green indicator light flashes slowly.
Over-voltage Protection Point
Over-voltage protection comes with a restoration function, and the over- voltage protection point is 15-16V when it’s in no-load condition. The recovery voltage of over-voltage is 14-15.5V. The green indicator light flashes slowly when in over-voltage protection.

Usage Steps

1. Open the package box and fetch the product out.
2. Make sure the voltage of your battery matches the input voltage labeled in the product.
3. Link the Red clamp to the positive terminal and the Black clamp to the negative terminal of the battery, and check them again if fixed tightly.
4. Connect the clamps into the battery before the power switch is ON.(the Red clamp to the positive terminal and the Black clamp to the negative terminal.
5. Start the inverter after connecting to the battery, the load voltage should match the labeled voltage.
6. Keep the 20cm distance from the inverter workspace in order to dissipate heat. Please keep it away from dust, high pollution and other adverse conditions.

•  Check if the LED lamp is green and then it can be used normally. If it is abnormal, please refer to Item 9 (troubleshooting) or contact the customer service team to help you solve it.
• Connect your devices to AC or USB ports.
• When you need to replace the fuse, please take down the fuse cover (do not need to unscrew the screw). then use the pliers to pull out the fuse and replace it with a spare fuse(40A/32V).

Troubleshooting and Solutions

In order to facilitate customers to troubleshoot the use of the product, please refer to the following table of LED status.

capacity. In this case, the USB works normally.
Red light flashes| Overload protection| 1. Pull your devices out. When the LED turns to show a solid green light, the inverter will work properly.
2. Unload. If the LED light is not restored to be green, then you need to restart the switch.
3.In this case USB ports can work.
The red light is always on| Short-circuit protection| 1. Turn off the inverter by pressing the button, and restart after the red light has gone out. The inverter will work after it has a solid green light.
2. In this case USB ports can work normally.
Green and red light alternatively flashes| Overheat protection or fan does not run| 1. Pull your devices out. wait for 3-5 minutes to restart. When the LED turns to show a solid green light, the inverter will work properly.
2.If the inverter doesn’t work after being restarted, please wait for a few minutes until the temperature inside turns to be normal.
3.Plug out or turn off your devices, allow the fan to run for 3-5 minutes. When the LED turns to show a solid green light, the converter will work properly.
4.In this case USB ports can work.
off| The inverter hasn’t been started up or doesn’t work, or fuse blew| 1. Check whether the switch is turned on.
2. Check whether the cigarette lighter port is damaged or unable to supply power.
3. Neither the USB nor AC ports work in this case.
