I'm going on a trip and I'm taking a power bank with me.
For example, if you go cycling or visit places where you cannot easily charge your phone every day or twice a day, you will soon need a strong power bank.
You already have power banks of 5,000 mAh, but also much larger ones.
What exactly should you pay attention to? CoolBlue is kind enough to add how often you can charge your phone with a power bank. For example, the Belkin BoostCharge Power Bank 20,000 mAh with Fast Charging Black can charge your phone 4 times according to CoolBlue.
