Small power banks that have under 10.000 mAh of energy capacity will not be suitable because they do not have enough power to supply the laptop battery. It might not charge the laptop device at all. Worse, it can even drain out the laptop battery energy you are trying to recharge.
How do power banks work?
To make it simple, there are 3 main elements to consider.
1/ A power bank is a high energy battery by itself.
2/ The battery has to be filled with energy in order to work.
3/ The purpose is to recharge other smaller mobile device batteries.
A power bank is made of high energy capacity batteries. Those batteries are mainly made out of lithium. Power banks are basically energy containers which have to be filled before to be able give back the energy to other devices. it has input and output ports. The input socket is to recharge the power bank itself.
A power bank is charged the same way as other mobile devices using a wire or using a wireless recharger. Using a wire, you attached the charging wire into the power bank input port and the other side into the charger. Plug the charger into the grid and wait. As far as the wireless is concerned you just put the power bank on top of the recharger. The recharging time depends on different factors, such as the power bank capacity and the charge level. Power banks usually have an LED indicator that indicates the current charge level capacity. The charge cuts off when it reaches 100% energy capacity.
Output ports are used for recharging external devices. Charging one or several mobile devices depends on the power bank total energy capacity. The power bank energy capacity is mesured with milliAmp Hours (mAh).
