Nothing is more annoying than when the car won’t start. As a rule, the car battery is empty because it has already been used too much or you forgot to turn off the lights. This can happen just as quickly in winter as in summer or on a trip. If the car no longer starts, you usually need help from another road user, a jumper cable and the knowledge of where to connect the cable. This is often not easy with newer vehicles.
With the portable and easy-to-use Jump Starter from Foursun, you always have a starting aid with you, and much more. Our test gives an overview of what the device can do. The Foursun Portable Car Jump Starter offers numerous features in a single device. For long-distance travel and camping, the jump starter booster is truly a valuable gadget for all cars and vehicles with 12-volt batteries, also because of the integrated compressor. The device can also be used sensibly in agriculture for small tractors. This allows tires to be stabilized at least long enough to reach a safe parking space or perhaps even a workshop. With a price of just 84 Euro at Banggood with the coupon code BG82d39c (poisonous until May 31, 2024), the mobile jump starter solution is very affordable.
Design & scope of delivery
The Foursun car jump starter comes with a sturdy carrying case that contains everything you need and still has space for additional charging cables. The device itself makes a very stable impression. It consists of a square box with four red covers behind which the various functions are integrated.
The most important function is the ability to start a car. To do this, connect the device to the battery or the corresponding locations in the vehicle using the included clips and the other side of the cable to the output of the car jump starter. The high-quality cables are gold-plated, the connection has an integrated protection circuit that protects against overcurrent, short circuit, overload, overvoltage and overcharging. Turn on the device using the sturdy toggle switch. The device offers 4000 amps when starting vehicles with 12 volts. You can now start your car normally. In our tests, this also worked without any problems with a Renault van.
A compressor is also integrated. This allows users to pump air into tires at up to 150 PSI. The compressor is controlled via the integrated LCD monitor and the included buttons. The pressure can be specified with these. The pump cylinder creates 25 bar. All of this is possible with the integrated battery with 26,800 milliamp hours (mAh). But that is not all. You can also use the Foursun car jump starter as a high-performance lamp if the vehicle breaks down. The emergency LED light with 5 watts provides enough lighting so that you can either repair the car at night, bridge the battery, or carry out other actions on the vehicle that require a light.
At the same time, you can use the car jump starter as a power bank (best list) for a smartphone or tablet. There are two USB-A outputs protected with covers (1x USB 3.0 and 1x USB 2.0). The USB output offers 5 volts with 2.4 amps, 9 volts with 2 amps and 12 volts with 1.5 amps. There is also another USB output with 5 volts and 2.1 amps. The jump starter can be charged using the included USB cable and the USB-C input (support for QC 2.0 charging).
Furnishing
The Foursun car jump starter can provide 12 volts to 16.8 volts and 10 amps in DC output. The jump starter offers 4000 amps and 26,800 milliamp hours (mAh). This means that almost all petrol and diesel engines with 12-volt batteries can be started. According to the manufacturer, this works down to minus 20 degrees. The compressor delivers up to 45 liters per minute and various adapters for valves are included. Cars, bicycles, motorcycles, balls and toys can be filled, but not truck tires.
In addition to the two USB outputs for operating 12-volt devices using the integrated battery, there is another output with an adapter for a 12-volt socket. This can be used to supply power to other 12-volt devices, like a cigarette lighter.
Application
Using the device is very simple. For the car jump starter it is sufficient to connect the clips to the jump starter and then to the battery. The car can then be started. The same thing happens with the compressor. You roll out the tube on the back, set the desired pressure using the buttons and the LCD monitor and connect the tube to the appropriate adapter on the respective tire. When you turn on the compressor, it pumps air into the tire. There is a toggle switch to turn it on and off, which is easy to find even in the dark.
