It does its job very well. It starts the car with a bang (engine size - 1.8) and the cold does not interfere with it. My battery runs out often, so I appreciated the purchase: it immediately became easier to live. I have enough for 6-7 starts. It charges the laptop, everything is ok in this regard, but I didn’t take it for this. Inexpensive, simple, small. Everything you need is included, including the case. And most importantly, it works well.
