I can't live without this device anymore, maybe there are better and worse, but what you have an older vehicle that occasionally gets upset when starting, it's a big help

I may have stumbled upon an exceptional piece of poor quality. However, I have to complain - indeed the mobile only charges to 98% and is completely discharged.
Looks sturdy, but the batteries are really weak
It won't even charge a normal mobile phone
I received it loaded to only one comma
The VW 1.4 MPi petrol engine wouldn't start when the battery in my car died. The device has been charged to 100%
Skoda Superb 1 1.9 TDi 96kW engine turned over twice and again discharged from 100% charge to zero
The micro USB connector is almost unused. It would be preferable to use standard USB-C for charging

For anyone thinking of buying a powerbank for starting - it's an incredibly practical thing. I have had this particular one for over two years. I've used it on my car, and at least five times I've lent it to someone who was nearby and had a flat. It has always worked without any problems, from small car to SUV. It couldn't be easier to use - plugs into the battery, turns on. you're taking off.
I carry it in my car all the time and I'm comfortable that not starting the car due to a dead battery won't be a problem for me anywhere. It is lightweight, works as a flashlight and has a USB output so it can be used as a normal power bank. It's a good idea to check the charge level every few months or recharge it. Anyway, it doesn't discharge itself very quickly. Overall - I definitely recommend it.
Works reliably
Lightweight
