Powerbanks
Need a powerbank? Even the biggest battery sometimes runs out of power. And let that often be at the least convenient time. Powerbanks were invented for those situations. Charge your smartphone or tablet in no time. All available externally rechargeable batteries can be found here.
A powerbank is a battery with a USB port. The sole purpose of a powerbank is to charge another device. Think of a smartphone, a tablet or wireless earbuds. You have powerbanks in all kinds of sizes, from large to small. What to look out for when buying one, we explain here.
Choose the right capacity
Usually, the bigger the power bank, the bigger the battery it contains. We express the size of a battery in mAh; milliamp-hour. The higher this number, the more power will fit into the powerbank. More convenient is to express the size of the powerbank in how many times you can charge your phone with it. Use the following table here:
- To 5,000 mAh: charge your phone once
- To 10,000 mAh: charge your phone 2x
- To 20,000 mAh: charge your phone 4x or charge your tablet 1.5x
- From 25,000 mAh: Charge multiple devices
Of course, you don't want to spend too long on the charger, even if it is mobile itself. Therefore, choose a charger that matches your smartphone. If your smartphone uses one of the following fast-charging technologies, it is advisable to buy a powerbank that supports it;
- Qualcomm Quick Charge
- Samsung Adaptive Fast Charge
- Oppo/OnePlus SuperVOOC
Note that a compatible USB cable must be used with this type of fast-charging technology. This is because of the higher powers and then certain requirements apply to the cable.
Tips when picking a powerbank
Want to be able to charge several devices at once? Then choose a powerbank with at least 2 USB ports. Do you also want to be able to charge older devices? Then make sure your powerbank also has a USB-A port, which fits older cables better. Otherwise, opt for USB-C.
Want to go through life even more mobile? Then look for powerbanks with wireless charging. You then place your phone on the powerbank to charge it. That saves on cables. Provided your mobile phone supports it, of course.
