So-called battery packs are available for this purpose. These packs can be charged at home like a normal battery and are often so small that they fit in your pocket. If your phone’s battery is depleted on the road, you can easily recharge the battery pack and your phone will recharge.
There are now numerous suppliers and products on the market – so you quickly lose track of everything.
You should pay attention to the following things:
- Milliamp hours (mAh) – 4,500 mAh is sufficient for the current smartphone battery to charge the device twice.
- Performance – the higher the output power, the faster your phone recharges.
- Design – maybe not the most important point, but it should be nice to look at.
