Everything in the purchase suits, a very necessary product.

In winter, I rarely use a car, so the battery loses capacity in the cold and it is not always possible to start the engine. Decided to buy this device. I've used it several times already, both with a dead battery and with a completely discharged one. In all cases, the engine started, but only in the “Boost” mode (without it, when trying to start, the dashboard completely went out). Motor 1.6.
I also tried to charge the phone with a battery discharged to 20%. After charging the phone, the JSL-12022 still showed 100% charge (although I think that it really was ~ 80% left).
A good device, there is always a certainty that the engine will be able to start, but you need to get used to the features of the buttons.

Pros

Compact size Ease of connection Can be used as Powerbank Quality build Convenient case

Cons

I won’t say that this is a drawback, but there is a possibility that while carrying a case in your hand, you can accidentally press the power button several times, the flashlight will work and drain the battery (there was such a case, since I decided to look at the charge in advance, the flashlight was on, the battery was 25% charged) . The Boost button is very small and slightly recessed, in good frost it is not always clear whether it was pressed or not.
