Rating of the best laptop power banks for 2024

The single drawback of today's laptops is still their independent power supply. The average device is capable of "stretching" from 5 to 9 hours in autonomous mode. The gadget, whose name is Power Bank.

Why does a laptop need its own Power Bank?

The main reason for this injustice is that from the very beginning, portable batteries were not designed for laptops at all. The first examples of today's Power Banks were compact Power Tube capsules with a finger-type battery inside.

They were published back in 2001, but the subsequent modernization and incredible demand for power banks, which began some time after the unprecedented development of the number of smart devices, determined their improvement.

Only with the growing popularity of external batteries began to talk about gadgets that will be intended for laptops. By the way, for the latter it was necessary to start producing completely new power banks - with much more capacitive and heavy batteries, as well as impressive output parameters.

These devices will cost more and it is for this reason that they are now unable to push ordinary external batteries for phones out of the market. In addition, in order to charge a laptop from such a device, they must be compatible.

Criteria for choosing a power bank for laptops

How to choose an external laptop battery correctly? Simple, if you are guided by the following parameters.

Ports

A laptop is a powerful device, so it cannot be charged via an ordinary USB slot and for this reason. USB standards were shown to the world back in the 90s. last century. Since that time, a huge number of types of USB slots have been produced, for example, USB 2.0 Type A Plug or Type B Jack, but all of them are designed for low power, so you cannot recharge laptops through them. In addition, the power of the devices is rapidly increasing every year. In this regard, the companies decided to simplify their own lives by producing a new standard and a multifunctional slot with a power reserve.

Thus, the USB 3.1 standard was developed and, accordingly, the Type-C slot, which is designed for currents with a power of 100 W, however, the presence of a double-sided Type-C 3.1 standard slot in a laptop does not ensure its functioning from an external battery, since in addition, a compatible one is required. standard cord.

If the Power Bank for a laptop is of good quality and comes with its own cord of the aforementioned compatibility, then everything is fine, but if there is none, then the cord must be purchased with complete seriousness, since 100W is a serious matter.

From a technical point of view, the Type-C cord can be made in such a way that it will also meet the 2.0 standard, and not the innovative 3.1, which is often done by manufacturers of budget cables. Affordable Type-C cords are sometimes made to past standards with out-of-the-box speed and power limits.Ideally, they will not allow the laptop to charge, but in the worst case, they can disable it.

A USB Type-C charging cord must be certified and meet the necessary requirements, but it is possible to recharge a laptop via Power Bank not only through the USB Type-C 3.1 slot.

Most powerful Power Banks have their own connectors for connecting laptops. At the same time, universal Power Banks designed for laptops come with various adapters so that you can connect almost any gadget. These slots were designed from the very beginning for higher current and voltage ratings.

Voltage and current

The Power Bank models available on the market are largely designed for recharging mobile devices, smartwatches and other weak electronics. In this regard, their output voltage is often equal to 5 V, since this is the most popular parameter for innovative gadgets.

A small current is also used to charge such devices - about 1 A, however, a laptop cannot be recharged at such low values. It needs an output voltage that is more than 12V. It is worth noting that most innovative laptops need a voltage of 15 to 20V, so Power Banks are often equipped with 16 and 19V switches.

The current in order to charge a powerful laptop must also be higher than for tablet PCs or phones (somewhere from 3 A). For example, in the multifunctional Power Bank Pitatel NPS-153, the maximum output current is 4.75 A, and the MAXOAK K2 Laptop power bank is capable of providing up to 5 A.

If the current is much lower than what the gadget needs, then the laptop will recover its charge over a very long period of time.

In such a situation, it is impossible to talk about any work on a laptop while charging from the Power Bank. The power bank is able to react to an overcurrent and shut down.

Capacity

This characteristic is also important, since notebooks consume a lot of energy and have sufficient battery capacity. Powerbanks designed to charge laptops, as a rule, have a capacity of more than 10 thousand mAh, while the average models designed for charging smart devices can have a capacity of 5000 mAh.

Since the latter from the very beginning are intended for weak devices, they also have low output characteristics with respect to voltage and current. Do not lose sight of the fact that not a single model of a power bank designed for a laptop gives all the capacity due to the inevitable loss of energy during its change.

For example, a model with a capacity of 20,000 mAh is only able to provide about 14,000 mAh. In other words, in order for a laptop to work for a long time, it is recommended to buy a model with an excellent reserve of capacity, however, it is necessary to chase devices with an incredible capacity carefully, since there are many fakes in this segment.

It will not be superfluous to mention that high quality gadgets with good capacity will cost more and will be heavier.

Functionality

To draw attention to their own products, manufacturers sometimes write that their "brainchild" is universal. In other words, this means that the bank connects to everything: both to the machine and to productive laptops, however, you don't need to believe everything that is written, it is better to double-check.

A study of the outlet parameters and slots will make it possible to understand whether this device is capable of recharging laptops at all. In addition, experts advise you to check that the instructions for using the model indicate the function of recharging the laptop and indicate through which slot or cord to do this. Some manufacturers also write the approximate number of laptop recharges.
