AUTOWIT Super Cap 2 Jump Starter in the test!

A few days ago the manufacturer Autowit asked us the so-called "AUTOWIT SuperCap 2 Jump Starter“To try. After an ultra-short delivery time, the device was there in a neatly packaged pouch, waiting to be tried out. The first impression was extremely positive, because the robust packaging, the device itself and its accessories make a high-quality impression. Connection cable (Starter cable, USB charging cable, vehicle charging cable) are stored in a separate compartment with a zipper and are therefore always at hand when it is needed. Incidentally, a charger for the socket is not included in the scope of delivery. Charging works very easily with any USB charger and the supplied micro USB cable. We have the AUTOWIT SuperCap 2 Jump Starter with a conventional - but pretty strong - USB charger charged in just over 2 hours.

Update: We made a mistake!

The initially extremely fast charging was deceptive, however, because from around 30% charging is much slower. Autowit, on the other hand, states that it can be used in approx. 12 minutes at 3V, in approx. 6 minutes at 20V and in approx. 5 minutes at 30V. We CANNOT confirm that, because in our test a small four-cylinder could only be started when the battery charge shows over 90%. You can't do that in the given time. Yes, more on that later. The big surprise followed "before" the test on the vehicle. Since this should not be carried out until the next day, the device was put aside. The battery was charged after a good 24 hours - without use - but dropped to almost 60%. Why that? So if the part has been in the vehicle for a week at low temperatures, is it completely discharged? Any simple power bank can do that much better and that is actually a manslaughter argument as we find it.

So we reloaded the device and went out to the car. The test object was an Audi A3 8P with a 1.8tfsi four-cylinder. We “killed” the battery in advance with all possible consumers, so that starting was no longer possible. The battery was so empty that it would not have been possible to recharge the battery pack. The preparation time of approx. 1 hour led to a discharge of a few percent again. However, our attempt to start then worked perfectly. Plug in the device according to the instructions, activate it, enter the vehicle within 10 seconds and start the car when a continuous beep sounds. However, that only worked exactly once! Experiment number 2 was nipped in the bud with the indication "Low Battery". The battery charge had already shrunk to almost 70% from the start and a few minutes without use. And “reloading” on another vehicle was also not successful. The help of the other vehicle battery has the Super Cap 2 Jump Starter not can charge.

Malfunction? Or state of the art?

At this point we are unanimously of the opinion that the device may be defective. There is still no information available. If not, it would be pretty embarrassing for the developers. We then of necessity started our Audi in the classic way using jump leads and the other vehicle and thus the time-consuming method with the Autowit SuperCap 2 waived. The self-discharging battery unfortunately leaves us with the test result inadequate come. The alleged possibility of being able to charge the device with another functioning vehicle battery or by means of a cigarette connection is of no use. If you have another vehicle at hand, you can use it to give jump-start help. Sorry AUTOWIT - that was nothing!

Super capacitor vs battery AUTOWIT Super Cap 2 Jump Starter in the test!

Update from 10.09.2020

At this point we have to admit that, especially with regard to the built-in technology, a serious mistake has been made. What we have completely overlooked is the fact that it is a "battery-free device"Which instead works with a" super capacitor ". Even though it is printed in large letters on the box! Sorry for that! Such a capacitor is usually unbreakable compared to a battery pack, but only stores the energy for a certain period of time. This of course explains the rapid discharge and also the fact that a second attempt to start was not possible and the 15 times we assumed in the video certainly not. However, it does not explain why the device could not be recharged on an intact and 100% charged vehicle battery. But it still changes ours At the end... In our case, the AUTOWIT Super Cap 2 Jump Starter did what it should. We are currently assuming a malfunction with regard to reloading / charging via the vehicle battery. However, this malfunction still leaves an unpleasant aftertaste! Buy Autowit Jump Starter2 (10% discount code: tuning10xm)
