Is there a powerbank suitable for Lenovo ThinkPad Edge 14?

Question

Charger

Good day!
Unfortunately, I don’t understand anything about the compatibility of powerbanks and devices, so I turn to experts.
Please help me choose a bank suitable for Lenovo ThinkPad Edge 14. Batteries die like flies, so I want to have a device in stock that can charge a laptop 1-2 times, and at the same time a smartphone. For the latter, it is very easy to pick up, but for laptops it is problematic.

Answer 1

From the most inexpensive (+ normal in quality) that can charge your laptop at least once, here:

+ _you_ buy normal high-quality batteries (8 pieces ), for example, these (the most capacious today):

of course you can buy everything ready-made like this

or this

but who knows what kind of shitty batteries are inside, and whether they can be replaced after a couple years (hint: you have to solder). and they are more bulky, with the same capacity (the Chinese put banks at 2200, and we - at 3500)
I have been using this one for the fifth year now, from the same company (although a maximum of 13 volts, the laptop does not pull)

PS you may need an adapter for a Lenovo plug , these are already separate troubles, I got it on ebay
