The Best Laptop Power Bank Buying Guide

Are you often on the road with your laptop but struggling to keep up with its battery life? A laptop power bank might be just what you're looking for. With a laptop charger power bank, you can keep your laptop fueled up anywhere, at any time, without worrying about running out of electricity. In this post, we will look at the best laptop portable charger list on the market and what to look for when making a purchase.

If you're looking for a laptop power bank, make sure you pick a high-quality portable charger that is compatible with your device. However, with so many power banks on the market, it is difficult to know which to choose.

1. Capacity for Charging

The charging capacity of a power bank is measured in milliampere hours (mAh) and is one of the most significant elements to consider when selecting a laptop power bank.

Laptop batteries are large, thus it takes a lot of mAh to completely charge one. As a result, we recommend purchasing a power bank with a capacity of at least 20,000mAh. This should be plenty to charge the finest laptops with a power bank at least once.

2. Charging Input and Output

You should make certain that your power bank has a high charging output and input. The faster your laptop charges, the higher the output amperage. We recommend that the power bank's output be 60W or above in order for it to charge your laptop. Likewise, the greater the input amperage, the faster your power bank will recharge. The AOHI 30000mah has a high power input of 100W, which is one of the greatest in the world. That implies a 30000mah power bank can only be fully charged in 2 hours.

To clarify, below is the difference between AOHI's 100W output power bank and others' 60W:

Get a gadget with a high watt-output rating if you wish to transmit energy from your battery bank to your laptop. This manner, you can fast charge your computer and eliminate the power bank clutter on your desk.

3. The power bank's batteries

When purchasing a power bank, lithium ion cells are recognized to be the superior and safest option. It typically employs two sorts of models: 21700 and 18650. However, lithium ion 21700 batteries outperform 18650s in terms of capacity and charging speed, thus we picked 21700 as our cells. The 21700 cell contains 50% more energy than the 18650 cell, and its larger size lowers heat transmission to the environment, making it safer to use. They also have a longer cycle life than 18650 batteries, so they don't wear out as rapidly.  

4. Port Quantity and Type

Pay close attention to the power bank's output ports. Make sure it has the right ports so you can charge your gadgets with it. Some of the most popular connectors on power banks are USB-C, Micro USB, and Lightning.

Look for a power bank with numerous USB connections, including USB-C and USB-A connectors, as some laptop power banks let you charge multiple devices at once. It is preferable to have both USB-C and USB-A ports available at once.

Many people charge their computers, tablets, and cellphones using power banks with USB-C output. Numerous tiny gadgets, such as wireless mice, headphones, and phones, accept USB-A charging.

Power banks with USB-C connectors that enable Power Delivery (PD) technology offer some of the quickest charging (output) and recharging (input) rates available.

5. Construction Quality

Power banks constructed of low-quality materials, such as low-quality plastics and inferior materials, are more prone to harm.

You want a power bank that can endure accidental bumps as well as weather extremes. Select versions with casings composed of more durable materials such as silicone rubber, polycarbonate, and anodized aluminum. Aluminum alloy and aerospace materials are used in AOHI's power bank, making it more wear-resistant and robust.


Laptop power banks are available in a variety of designs and sizes. Some are small and light enough to fit in a laptop bag or backpack, while others are larger and bulkier.

Larger and heavier power banks provide more charging capacity, so strike a balance between mobility and energy capacity. If you intend to transport it on the go, we recommend power banks weighing is around a pound.

7. Security Features

Imperfect circuitry and overcharging are the two most typical causes of power bank explosions. As a result, it's best to opt for a power bank with built-in protection against overcharging, short-circuiting, and overheating.

Consider power banks with lithium-polymer batteries as well. These battery types are regarded safer than lithium-ion competitors due to their strong packaging.

8. LED Indicators

You may use the LED indication lights on a power bank to check its charging state and remaining energy, therefore choose a power bank with visible LED indicator lights. If it doesn't have an LED indication, you'll have to use your best judgment to figure out when to charge it, which might be inconvenient.


Finally, selecting the finest laptop power bank is critical for assuring your productivity while on the road. Consider capacity, power output, mobility, and connectivity choices when determining the best match for your needs. AOHI 30000mah power bank stands out among the best alternatives in the industry for its remarkable performance and dependability. These power banks will not disappoint you if you are a regular traveler, a digital nomad, or simply someone who wants a reliable power supply for their laptop.
