It is strange that the 20220 mAh model is not on sale, after all, my car needs something more powerful than 18000. But in principle, with a boost, a 3.6-liter engine with a car battery discharged to 0 and near-zero temperature starts. Similarly, a three-liter Audi engine with a dead native battery started up much easier even at -10. Got pros: First of all, mobility, a small power bank for cars, convenient connectors for connecting to a regular car battery - no need to worry about lighting up, etc. Different cons: no usb type c adapter to charge laptop. For the phone, this adapter is included. The need to store the device at home - it does not tolerate frost, you can’t leave it in a car.
