In point #2, we determined that the conversion efficiency of a 100Wh power bank with premium quality cells would likely drop to about 70% conversion efficiency due to the high charging current (96W watts) of our example laptop, resulting in about 70Wh being transferred to the example laptop battery (70% more battery life). In point #1, we determined the example laptopвЂ™s internal battery size (100Wh). LetвЂ™s refer back to our original example for the last time and put everything together: A laptop switching to a different power mode can be a somewhat obvious event because the screen brightness will typically increase and/or backlit keyboards will illuminate, but it isnвЂ™t always this apparent so be sure to check the power settings on your laptop to see how it changes when itвЂ™s plugged in and when itвЂ™s using battery power. One thing thatвЂ™s easy to overlook is that your laptop may switch to a different power mode when itвЂ™s connected to a charger, as it doesnвЂ™t notice the difference between different types of external power sources (power bank, car charger, wall charger, etc.). If you plan to use the power bank as a substitute for a wall charger so that you can recharge your laptop while still using it, the power bank wonвЂ™t last as long before it needs to be recharged. Another reason being that computers tend to recharge at lower currents when they are shutdown because additional power isnвЂ™t needed to operate the computer, which will help the conversion efficiency between the power bank and laptop. The first reason is because none of the power is being used while the computer is recharging. If you plan to shutdown your laptop when the battery is low before connecting a power bank to recharge it, this will help the power bank quickly and efficiently recharge your laptop battery.

This is something that is easy to overlook, but itвЂ™s very important to consider. Think about how you intend to use a power bank to recharge your laptop. Since the laptop can charge at up to 96 watts and has a 100Wh internal battery, it would be more realistic to anticipate that a power bank with premium internal cells would provide up to 0.7 charges (70% more battery life).Д¤.

In our previous example using the MacBook Pro 16вЂќ, a 100Wh power bank would be comparable.

Power banks that use high-quality internal cells will perform toward the higher end of this range, but these products are usually more expensive because premium internal cells are considerably more expensive. Most experts say that the average conversion efficiency range is between 60% to 80% for charging small devices (phone, tablet, headphones, etc.), so this could be slightly lower for larger devices (such as a laptop).

The conversion efficiency will vary greatly. For computers that use a large amount of power (over 65W), this will also cause more heat to be generated, resulting in more power loss. As the power leaves the power bank and passes through the cable to your computer, you can anticipate that some power will be lost. As the voltage from the power bank is increased to the 20V current that the computer needs, heat is generated and some power will be lost. Most laptops charge at a current around 20V, which is significantly higher than the nominal voltage of the power bank (3.7V). Some of the most common ones are cable length, high charging voltages/currents, heat and the battery health of the computer. There are many things that can impact this. 'Conversion efficiencyвЂќ, is basically a comparison of how much power reaches the device being charged compared to how much power is transferred. Here's why ' conversion efficiency' matters. Power will be lost while it is transferred from the power bank to your computer.
