Powerbank Selection
Not every power bank is made equal, and not everyone can support a laptop’s power requirements.The following factors should be taken into account when selecting the best one:
- Capacity: The power bank’s capacity, measured in mAh (milliampere-hours), dictates how much energy it can store. Look for a power bank that can hold two to three times the amount of juice that your laptop battery can hold. Select a power bank with 10,000–15,000 mAh, for instance, if the battery in your laptop is just 5000 mAh.
- Output: Look for a power bank that can sustain an output of at least 18 or 20 watts and has a USB-C PD (Power Delivery) connection. This provides sufficient power for effective charging and guarantees compatibility with the majority of modern laptops. Check the specifications for charging your laptop again because some may need voltages higher than 20W.
- Ports: Check that the USB-C port on the power bank matches the charging port on your laptop. Select a power bank with both USB-C and USB-A connectors for more compatibility, as some laptops may only have USB-A ports that are outdated.
Cable Connection
The type of cable you use is very important for effective charging. Select the best USB-C to USB-C cable with USB PD compatibility. For best results, make sure the cable’s rating (e.g., 18W or 20W) matches the power bank’s output.
Charge
- Power bank Charge: Make sure your power bank is completely charged before starting your mobile charging journey. When your laptop needs an extra boost, an empty battery bank won’t be of much use.
- Connect the laptop: Connect the USB-C PD port on the power bank to the charging port on your laptop using the selected USB-C cable.
- Turn on the power bank: There is typically a power button or indication light on power banks. Turn it on to begin the process of charging.
Battery Optimization
Keep in mind these suggestions for quicker charging and longer battery life while your laptop is connected to the power bank:
- Screen brightness: The display consumes a lot of battery life. Power consumption can be significantly decreased by lowering the brightness.
- Unnecessary programs: The battery is drained by background activities and unused tabs.Any open programs should be closed.
- Power saving mode: Power-saving modes on laptops maximize battery life. When the power bank is connected, turn on this mode to extend the battery’s life.
- Demanding tasks: Even with a power bank plugged in, intensive tasks like video editing or gaming quickly drain the battery. Put these things off until you’re close to an outlet.
Limitation
Even though they are quite useful, power banks have drawbacks.Here are some things to keep in mind:
- Charging speed: Laptops are usually charged more slowly by a power bank than by the original chargers. Be patient and adjust your expectations if necessary.
- laptops compatible: Some older laptops may be incompatible with USB-C PD charging. For confirmation, check the owner’s manual or the manufacturer’s website.
- Multiple charges: You might need to recharge your power bank before completely charging your laptop, depending on the capacity of the power bank and the size of the battery in your laptop.
