Power Bank is a device common among users of portable gadgets for replenishing energy reserves. Power bank is use to charge smartphones, smart watches and fitness bracelets. But today Power Bank Price in Pakistan is decreases When many users buy this and work in conditions of rolling and emergency power outages. Many are wondering if it is possible to charge laptops from Power Bank. Let’s see if it is possible and how to charge a laptop through Power Bank.
Criteria for choosing a power bank for charging a laptop
And here the second question arises: is it possible to charge a laptop from Power Bank for a mobile phone? Unlikely! Since a power bank of low or medium power is enough to replenish the energy reserve of a smartphone. But a laptop needs a more powerful and energy-intensive option, besides. Not all power banks are suitable for recharging laptops. Let us dwell in more detail on the main characteristics of power banks for laptops:
- Modern laptops are equip with capacious batteries. So, a portable charger with a capacity of up to 10000 mAh will not work. The best option is a power bank with a capacity of about 20,000-30,000 mAh.
- The second selection criterion is the current strength and voltage. We focus on the fact that laptops need a voltage of at least 15–20 V. The power of the power bank should be 20–30 V and higher. In this case, the nominal value of the current should be from 3 Amperes. Devices that are weaker in power will not cope with charging a laptop.
Also to the main technical parameters, users can choose the size and weight of the device. Stylistic design, more equipment. For example. Some models are equip with a flashlight, backlight, charge level indicator, display.
Devices differ in the type of case security:
- Universal portable power banks are compact in size and light in weight devices. Most often they are equip with a plastic or metal case without more shock protection.
- Shock-resistant or protected power banks are products with a durable and wear-resistant case. Designed in such a way that they can be use in extreme conditions. Such specimens are not afraid of dust, moisture, mechanical damage, extreme temperatures.
Charging a laptop through Power Bank: common methods
Now let’s take a closer look at how to charge a laptop from Power Bank.
Connecting a laptop to a power bank via a USB connector
As it turned out. Charging a laptop through a portable adapter is only possible with a USB Type-C port, also known as USB 3.1. Please note that such a connector is install by computer equipment manufacturers only in modern laptops. Older models with USB 2.0 or 3.0 connectors do not pass voltage over 4.5 V. And to recharge the laptop battery. You need power from 20–30 W and a voltage of at least 15–20 V.
According to experts, a USB Type-C port suitable for charging should be label D / DisplayPort or a “plug” icon. Otherwise, energy transfer manipulations will be unsuccessful.
Connecting a laptop to a power bank via a network cable connector
Is it possible to charge a laptop from a Power Bank without a USB 3.1 port? There is an option to connect a laptop to the charging unit via a network cable connector. To carry out this process, you will need an adapter that converts the output current from 2 Amperes to the appropriate one for a laptop. Such an adapter is rarely provided in the basic package. Our specialists can help with the selection of the necessary accessory.
Note that cutting edge models provide the ability to use standard charging for a laptop. Power Banks are equip with special sockets for an outlet.
How to charge a laptop from Power Bank: useful tips and rules
How to charge a laptop through Power Bank – figured it out. Now let’s find out if there are any restrictions, prohibited actions or recommendations. So, if a power supply with a rated voltage or power lower than that of a laptop charger is at hand. Then such charging will not bring proper success. It is also pointless to try to replenish the laptop’s battery power using USB 2.0 or 3.0. Energy is transfer here only to the output, so the bandwidth is not enough to charge a laptop. Of course, trying to charge a laptop without the use of more accessories and devices. For example, a solar battery, a generator, a “foreign” charge, will be a futile undertaking.
Transferring power from a portable charger to a laptop requires learning some rules. So, the charging unit must be 100% charged. If the device is new, then do not forget to charge and discharge the device for correct operation in the future.
Strict restrictions include the following useful recommendations and tips:
- It is forbid to charge devices using homemade power supplies. Even minor miscalculations in the assembly and manufacture of such devices. Can cause equipment to malfunction or even catch fire. Which is fraught with more serious consequences.
- You can not use the AC adapter from another laptop for power transmission. The power characteristics of which are much larger. Such actions lead to overheating and damage to computer equipment. Repairs often cost a lot of money, which is sometimes cheaper to buy a new laptop than to fix an old one.
- Using the direct connection method or charging the battery from the laptop is not the best solution. As a standard, this path is fraught with disabling the laptop.
Charging a laptop battery from a solar station
Today, solar chargers are becoming more and more popular. And, as it turned out, such devices do an excellent job of charging laptops. There are similar power banks according to the principle of operation and design features.
The first group is solar batteries or panels with a large absorption area. There are also the names “frame, folding or unfolding” panels with a power of solar components of 15–20 watts. The mechanism of action is very simple: you need to deploy a panel in an area open to the sun and connect a laptop to it. The advantage of such a solar battery is the fact that the energy transfer occurs immediately after connection. That is, there is no need to wait until the battery integrated into the solar panel is recharg. As for the disadvantages, such a design cannot be call small-sized. And the product is also not suitable for use in the dark or cloudy time of the day.
The second group is external batteries with an integrated solar panel. The algorithm of action here is completely different. First you need to recharge the portable charging unit from the network. If a situation arises when power transfer is necessary. The laptop should be connect to the device. Using the solar pad in parallel to compensate for the self-discharge of the external battery. Such a Power Bank for charging a laptop is consider more efficient. Because it can be use regardless of the time of day or night.
At the end of our article. We note that the charging speed depends on the characteristics of the built-in batteries of the laptop and power bank. But the more powerful the portable charging adapter. The faster the laptop’s expended energy will be replenish. Taking into account the tips and recommendations described above. You can choose the best Power Bank and charge your laptop. So that your favorite gadget is always at hand and in working condition.
