Best Laptop Power Bank; Factors To Consider When Choosing A Laptop Power Bank

Best Laptop Power Bank_ Factors To Consider When Choosing A Laptop Power Bank

When selecting a laptop power bank, you must look at certain factors. Here, I will be giving some factors that will guide you when you want to buy a laptop power bank.

Under specific requirements, a power bank can perform the same function as the laptop charger. This requirement includes a connector, voltage, and power.

The connector includes a compatible cable with that the laptop’s charging ports. Therefore, voltage is usually measured in volts, which should be the same as that of the laptop charger.

Finally, the power is measured in watts and should be the same or greater than the power supplied by the laptop charger.

Features of the laptop charger

It is essential to know the specifications of the laptop charger. This will help you know the laptop power bank to choose from.

The specification of the laptop charger has to match that of the laptop power bank you want to buy. To do this, check the laptop charger’s output parameters, including the voltage and the current or amperage.

What this helps you to know is that the laptop charger works at a particular voltage and supplies a maximum amount of current.

However, the charger does not indicate the maximum power it can supply. You can figure that out by multiplying the voltage by the current, and you will get an answer in watts.

With this, you will get the recommended power that the power bank should supply. It is essential to know this because it can damage your laptop if you get a power bank with a higher power.

Using the laptop power bank

After that first step, next is to find a power bank suitable for the laptop. This power bank must meet certain features.

These features include; charging ports, output port voltage, and power supplied.

Charging ports

A laptop has three different ways that it can be powered. This depends on the output port that the laptop has.

The laptop power banks types include power banks with AC ports, DC ports, and USB-C PD ports.

Output port voltage

It depends on the type of laptop power bank you choose to buy, either any of this one with AC, DC or USB-C PD ports. It is essential to check for the output port voltage of the power bank.

However, the output port voltage of the power bank should have the same voltage as the laptop charger. If not, it can damage the laptop.

You will always see the output voltage indicated on the power bank specification as DC output or USB-C PD output. It is usually measured in volts.

Also, you can see a model that may have one or more DC output ports with a fixed voltage. You can also find some that have single multi-voltage DC ports where you can select the voltage by pressing the power button to change the charging voltage of the laptop.

It is not necessary to check the voltage of an AC power bank. This is because it will continue to power the laptop with its charger.

The AC power bank is in charge of changing the voltage to that voltage of the laptop.

Power supplied

Lastly, another thing to consider is the amount of power supplied. This is usually measured in watts.

You should know the maximum amount of power that the output port of the laptop can supply by the power bank. For example, the maximum capacity of laptop power banks with DC is 130watts.

Thus, an AC and USB-C PD outputs are 85 watts and 45 watts, respectively. If a laptop uses a particular amount of wattage, it is advisable to choose a power bank with the same or higher power.

If not, the laptop would not even start up because it needs maximum power for its start-up and also for later use at the same time while it recharges the laptop battery.
