If you have ever turned the key and only heard a sad “click”, this text is for you – we will show you how to perform an emergency car start and a few additional garage tasks using professional Högert Technik jump starters.
Why have a starter device? Advantages of a jump starter.
A discharged battery doesn’t ask whether you have time – it simply immobilizes the car at home, at work or at a station in the middle of the night. In such situations a
starter device, commonly called a jump starter, becomes indispensable. It allows you to:
-
Start the car yourself with a 12-volt battery, without having to call costly roadside assistance. It’s real peace of mind that gives you independence.
-
Take care of safety – you don’t have to mess around with strangers’ cables and random cars in the parking lot. The whole process is safe and under your control.
-
Gain additional functions: many Högert Technik models are not only a booster but also a phone power bank, flashlight, and even a compressor or wireless charger – depending on the chosen model.
Which Högert Technik starter device models can you choose from?
On hoegert.com you will find several
jump starters – all offering a solid 400A starting current, but with different, useful additional features. This lets you pick the perfect
booster for your needs. Each of these models supports you in the same way: you can be sure you will start the car and finish your project – without the feeling that “you couldn’t do it”. That is the philosophy of
Högert Technik.

In practice this means that a capacitor starter device is a great “last-resort rescuer”: it can sit in the trunk for a long time, isn’t afraid of freezing temperatures, and prepares for operation very quickly, provided the car battery is not completely dead. It’s the ideal solution for those who value maximum reliability in all conditions.
How to safely use a jump starter? (step by step)
There is no room for guessing here – the scheme below applies to all
Högert Technik starter devices Högert Technik 400A), ensuring a safe and effective
emergency start.
Step 1 – preparing for an emergency start
- Make sure the booster is charged to at least 50%. The LED or LCD indicator will show the battery level.
- Check the car’s manual to see if the manufacturer allows external starting. This is crucial for the safety of your vehicle.
- Turn off the ignition and all consumers (lights, radio, fan).
Step 2 – correct connection of the jump starter clamps
- Insert the blue plug of the starting cable fully into the start port on the starter device – if it is not fully seated, it may melt.
- Connect the red clamp to the positive (+) terminal of the battery.
- Attach the black clamp to ground: a metal part of the engine or – if the vehicle manufacturer allows – to the negative terminal of the battery.
Step 3 – starting
- Turn on the jump starter with the power button and wait until two green indicators light up or a READY message appears (in models with an LCD).
- Try to start the engine – crank for up to about 5 seconds and take breaks so the device can cool down.
- After a successful start, first disconnect the cable from the device, then remove the clamps from the battery.
Step 4 – things to remember when using a starter device
- The minimum car battery voltage is about 2 V – with a “dead” battery below this value a car starter may not work.
-
A booster can perform several consecutive starts (usually up to 5), but after each it needs about a 30-second break and about 10 minutes to cool down after a series.
- Do not charge the device at temperatures below 0°C – this damages the lithium battery.
Capacitor jump starter – when is it the best choice?
For those seeking maximum reliability and resistance to extreme conditions, the Högert Technik HT8G625 is a real game changer. This is not an ordinary battery jump starter – it is a capacitor starter device that works on a completely different principle.
What if the car battery is completely dead?
If the car battery is completely dead (practically 0 V), the capacitor starter will have no source from which to “draw” energy to charge its capacitors. In that case you need to recharge it from another source – e.g. another working battery, the car’s 12 V socket, or even via USB (depending on the specific model and its functions). This makes it a reliable rescuer, but with a somewhat different usage profile.
How does this differ from a classic battery jump starter?
Let’s look at it from a DIYer’s perspective:
| Feature |
Capacitor |
Lithium-polymer |
| Energy storage |
Stored in an electric field |
Chemical storage |
| Readiness after long storage |
Almost always ready |
After several months without charging it may be discharged and require recharging |
| Operating temperature |
Works even at very low temperatures |
Capacity drops significantly in the cold |
| Cycle life |
Up to 10,000 charge/discharge cycles |
Usually hundreds to a few thousand cycles, with greater capacity loss over time |
| How to use |
You first need to charge the capacitors from the battery or another source (about 2 min) |
Ready “immediately” if it was previously charged and kept in readiness. |

Starter devices – overview of Högert Technik models
It’s not just a “car starter”. It’s a small power and support center in the field that expands the possibilities of your garage.
Power bank and fast charging
- All described models have a USB 3.0 port that can charge a phone with currents even 5V 3A, 9V 2A, 12V 1.5A – which means they also work as a fast power bank.
- Just plug in the included USB-C cable and hold the power button for about 3 seconds to activate charging.
10W wireless charger
- The HT8G623 model has a built-in 10W wireless charger – just place a compatible phone on the top surface of the jump starter.
- The device will stop charging and switch off automatically, and slight warming of the phone during charging is normal.
8 bar compressor
- The HT8G624 model has a built-in compressor with pressure up to 8 bar – simply connect the hose and threaded fitting to the tyre valve, set the target pressure and press the inflate button.
- The dual LCD shows the current pressure and the set value, and when the set level is reached the compressor switches off automatically.
- After 10 minutes of continuous operation the compressor needs about 15 minutes to cool down.
LED flashlight with SOS mode
- Every Högert Technik starter device has a built-in LED flashlight with three modes: constant light, flashing and SOS – you switch them with short presses of the button.
- This is particularly useful for night breakdowns or working on the car after dark, adding another safety element to your car starter.
The flashlight is not a “gadget” – it is real safety support in crisis situations.
