First, check the labeling on your power bank to understand its battery capacity and what input/output voltages and currents it supports. Most power banks can use a 5V/2A or 9V/2A charger for faster charging. If you travel internationally a lot, you might want to go for a charger that works with a wide input range of 100–240 volts.
The Li-ion or Lithium Polymer batteries in power banks have a fixed life cycle of nearly 400-500 charging cycles and the batteries begin to degrade after that. However, if you keep your power bank fully discharged or fully-charged for months, then it will lose quite a bit of capacity in just 5-10 charge-recharge cycles!
So, they use the Quick Charging option to speed up the charging times. However, this increases the stress on the battery cells in addition to the temperature and as a result your power bank's lifespan is going to be reduced.
You should therefore aim to not discharge the power banks below this level for long periods. On returning from a trip, if you see that your powerbank is depleted, then it is best to recharge it till half-full (two lights blinking in a four-light battery status indicator), before storing it for long periods.
Don't Charge the Battery Bank to 100% without Necessity Generally, most power banks come with Lithium Polymer or Lithium-Ion batteries, which lose some capacity after each cycle (charging/discharging). It also leads to overcharging, thereby causing unnecessary overheating.
