Why do you need a portable power bank?
Modern life requires us to keep our electronic devices charged and ready. A portable power bank is the best way to ensure you don’t lose battery power during an important phone call or while traveling. Which power bank is best for your lifestyle and your devices?
How to choose a power bank?
So you want a power bank with fast, efficient charging technology. Capacity is measured in milliampere hours (mAh). The higher the number the greater the capacity and the more devices you can charge before the power bank’s Lithium-ion battery needs its own charge. Speed is measured in watts (w).
How do I know the real capacity of a power bank?
The best way to know the real capacity of a power bank is to use a USB multimeter. The multimeter will show you exactly how much charge is transferred to a device. However, not everyone has a multimeter. So, down below we have also included a formula you can use to calculate the real capacity of a power bank and much more. Let’s dig in.
Does power bank capacity matter?
Simply put, capacity matters. It determines how many times you can use your power bank to charge your devices before the power bank itself needs to recharge. So you want a power bank with fast, efficient charging technology. Capacity is measured in milliampere hours (mAh).
How to connect a USB multimeter to a power bank?
Before you start, the USB multimeter should have a USB-C 5V charging port. Connect The Power Bank With the USB Multimeter – Turn the power bank on and using a USB-C 5V port connect it to the USB Multimeter. The multimeter LCD screen will show a 5V connection but a 0A output. The 0A is because you haven’t connected the charging device yet.
What voltage does a power bank use?
Most power banks use lithium batteries that have a voltage of 3.7V. When we charge a device using a power bank, we use USB-C ports that have a voltage of 5V. So, when the voltage conversion (from 3.7V to 5V) happens the capacity of the power bank changes, and some power is also lost.
