What is a pass through power bank and how does it work?
A pass through
power bank is a portable battery that allows you to charge your power bank and your device at the same time. This feature is especially useful when you're on the go and need to keep both your phone and power bank powered up without waiting for the power bank to charge first. The pass through charging function works by allowing the power bank to receive power from a wall outlet or USB port while simultaneously delivering power to your connected device. This is different from traditional power banks, which must be fully charged before they can be used to charge your phone. To understand how a pass through power bank works, consider the following:
- Pass Through Charging
- This is a feature that allows a power bank to charge your device while it is itself being charged.
- Input Port
- This is the port on the power bank where you plug in the charging cable to charge the power bank itself.
- Output Port
- This is the port on the power bank where you plug in your device to charge it.
Here’s how to use a pass through power bank effectively:
- Connect the power bank to a power source using the input port.
- Connect your device to the output port of the power bank.
- Both your power bank and your device will begin charging simultaneously.
This feature is particularly useful for travelers, commuters, and anyone who needs to stay connected throughout the day.
When should I use a pass through power bank instead of a regular power bank?
If you're in a situation where you need to charge your phone and your power bank at the same time, a pass through power bank is the better choice. Regular power banks require you to wait for them to charge fully before you can use them to charge your phone, which can be inconvenient in a hurry. For example, imagine you're at an airport and your phone is running low on battery. You have
a power bank with you, but it's also low on charge. With a regular power bank, you would need to charge it first before you can use it to charge your phone. With a pass through power bank, you can plug it into a power outlet and charge your phone at the same time. Here’s a comparison between a regular power bank and a pass through power bank:
| Feature | Regular Power Bank | Pass Through Power Bank |
| Charging Your Device While Charging the Power Bank | No | Yes |
| Convenience | Less convenient | More convenient |
| Use in Emergencies | Less effective | More effective |
In short, if you're looking for a power bank that can charge your phone and itself at the same time, a pass through power bank is the better option.
