The mobile booster of POWER PLUS is my second unit of this type. Previously, I had the blue Power Station of Einhell who persevered pretty much a 3/4 year. After that she has given up the ghost, and it just worked nothing. The unit of POWER PLUS is richer at the same price to some functions: so you have a much stronger illumination unit and can also activate a flashing light (eg in an emergency situation in the dark). Additional facilities at the front three 12V power outlets and a pressure gauge for the integrated compressor. This performs his work as loudly as the Einhell device, but works fine. I've been using it for bicycle tires, an inflatable paddling pool and also one for a flat car tire. In particular, the car tire, it took quite a while, but the required 2.4 bar pressure who delivered the unit without any problems. Practical: the hose, accessories and charger station can be stowed in the rear flap. The terminal clamps are securely fastened to the housing sides and make a thoroughly quality impression. To function and quality of jump start, I can not (yet) do not say anything because it was not necessary to happiness yet. Overall, the Mobile start using POWERPLUS do a very good, solid impression. When it comes to feel and quality should not expect miracles, but that is in the price, certainly none. Pleasantly surprised I'm mainly because the unit of POWER PLUS is always better processes and more functionality than the "German" brand product of company Einhell - with almost the same price. Those looking for an affordable mobile jump start and do not want to fill three car tires per day with the intergrierten compressor so here's the best advice.
