I'm very happy, it really is worth buying.

It performs its main function perfectly. A really powerful engine can start (well, hardly a 6 liter diesel engine, but the same gasoline one is quite). The capacity is high. If fully charged, then it will not be necessary to charge after 3-4 starts. A flashlight is also in place.

Pros

The capacity is really big. I’m not sure that it’s 16 Amp / h right, but I started the turbocharged one and a half times 3 times, while showing all 4 divisions of the charge filling. True, before that, after the first charge, it was discharged very quickly. Well, this, in my opinion, is standard practice for power banks. Built into the case is quite conveniently quite a suitable flashlight, which I was glad about, because I used it often (you can’t compare it with a flashlight in your phone).

Cons

There is no charger in the kit, you have to use third-party ones. Does not support fast charging (checked with a good memory through a usb tester), so the charging process takes hours. Actually, my Xiaomi power bank at 10 A / h behaves the same way, so this booster definitely has 10 A / h.
