    Ready to Charge Your Device

    Your new power bank is now ready to be used! Simply plug in your device and enjoy.

And there you have it! The simple process allows large quantities of power banks to be made at once for a lower cost. You now know how your power bank came to be one of your most important tech accessories.

If your device does not have a USB interface, you might still be able to use a power bank if wireless charging is a feature of both the device and charger. Before using your power bank, make sure that it provides proper voltage to adequately charge your device. You can always check with the manufacturer of your device if you are uncertain.

The following manufacturers make laptops that are USB-C compatible:

  • Dell
  • Apple
  • Asus
  • HP
  • Lenovo
  • Microsoft
  • LG

If your laptop does not support USB-C charging, you’ll need a power bank with a 12V output and a cable that fits the laptop’s charging port. If you are unsure if your power bank can charge your laptop, you can always reach out to the manufacturer!

Using a Low-Quality Power Bank

Using a Low-Quality Power Bank

Low-quality power banks aren’t all guaranteed to ruin your smartphone battery. However, if you are using it frequently and for long periods of time, it can cause damage to your phone’s battery by making it lose its charge faster. The best way to avoid this is to make sure you have a high-quality power bank, or to use your lower quality charger only when you need it most. Lower-quality power banks usually have small batteries, are low-cost, and provide insufficient power to your devices.

A Power Bank With Insufficient Voltage

A Power Bank With Insufficient Voltage

The power bank you use to charge your phone should have 5V. If your power bank has less voltage, it can drain your battery instead. If your power bank has a voltage greater than 5V, it can damage your phone by overloading the battery. Be sure to check the voltage of your power bank before using it to charge your phone.

Overcharging Your Phone

Overcharging Your Phone

Power banks aren’t designed to be constantly plugged into your phone to keep it at 100% battery life. If you constantly charge your phone, your battery will not be able to hold its charge for long periods of time. It is best to use your power bank sparingly and to unplug it from your phone when it’s close to being fully charged.

Following these tips will allow you to use your power bank without fear of damaging your smartphone! The best rule of thumb is to use your power bank only when you absolutely need it, and to unplug your phone after it has enough battery.

The Bottom Line

Power banks will always be a necessity because they provide the energy our phones, laptops, and tablets need each day. Through their simple manufacturing process and their capacity to charge a variety of devices, power banks are the ultimate tech accessory!
