I ordered this device. Solid pluses - multifunctional, good capacity. It is charged from the mains power supply or from the car cigarette lighter. I recommend it especially in winter when the battery freezes and the car won't start. You can charge your phone, which is not unimportant on the road, it will not be left without communication. Built-in flashlight. I advise you to buy, it’s easier to have such a booster than to wait for benefits from other car owners.
