How to charge a laptop using a power bank. TOP 3 Power Bank for PC

The widespread use of mobile devices powered by batteries requires solving the issue of replenishing battery energy at the right time. The standard way out of this situation is to connect the gadget to the network. But it is not always possible to power the device in this way - the outlet may not be accessible. For smartphones, this problem is often solved with the help of a wearable energy source - PowerBank (the not entirely correct pronunciation “power bank” has taken root). It is logical to try to restore energy reserves using a “power bank” for laptops as well. This is possible, but taking into account the specific power supply of wearable computers.

Is it possible to charge a laptop with an external battery?

You can charge using an external battery, but for this the battery must be powerful. A regular power bank designed for charging phones, headphones and other mobile devices will not charge a laptop. You will need a capacious and powerful model. Such devices, as a rule, have significant weight and size. A portable battery must be selected with suitable parameters in order to fully charge.

Which power bank can charge a laptop?

A selection of power banks for laptops

When buying a Power Bank for a laptop, you need to choose trusted manufacturers so that there are no problems with its use in the future. It is best to choose original chargers that are fully compatible with your computer. By choosing Chinese counterfeits, the buyer runs the risk of purchasing a low-quality battery. A little-known manufacturer may indicate a capacity of 20,000 mAh, but in reality the figure is much lower. A regular Power Bank will not work for charging a laptop.

The average laptop is equipped with a battery of approximately 10,000 mAh . Therefore, to perform one full charge, you will need an external battery with a capacity higher than this value. Before use, the Powerbank should be fully charged to 100 percent. To charge a gaming laptop, you will need an external battery with a capacity of 20,000 mAh.

A little about the specifics of power banks and popular manufacturing companies

The power bank itself can be charged either from the network or from a computer connected to the network - depending on the situation

When giving preference to one or another portable charger, it is important to keep in mind that not all models will allow you to work with a laptop and charge it at the same time

The most popular companies at the present stage are Xiaomi, Drobak, Power Plant. They produce universal power banks that can be used to charge any gadget, including laptop computers. A good power bank will have a durable body and reliable protection from environmental factors. As a rule, the housings of devices with an increased degree of security are painted orange or red.

The capacity of a power bank that is suitable specifically for charging a laptop should be at least 20,000 mAh, or more. The higher the power capacity, the longer the laptop will work.

If you prefer compactness, you can purchase an inexpensive Xiaomi Mi 20000 power bank. This power bank is remarkable in that you can work with a laptop while simultaneously charging it. The capacity of Xiaomi Mi is fully consistent with the required indicators - 20,000 mAh, and its light weight, about 400 grams, will allow you to carry it with you.

If you need a more powerful device, there is the Power Plant K2 50000, which is suitable for all laptop computers and can become simply irreplaceable in conditions of a long absence of mains power supply.

Using a power bank is very simple - you just need to choose the right device that matches the parameters of your laptop

When purchasing, also pay attention to the appearance, manufacturer and price. If you select a power bank that matches the characteristics of your computer, it will always help you out when access to the electrical network is impossible. https://www.youtube.com/embed/Gk2WRLSe3DE

What to look for when choosing a powerful power bank

To avoid making a mistake when purchasing, you should familiarize yourself with the technical data that a good Power Bank should have. The output voltage should be 16 - 20 Volts , and the rated current should be 3A. By choosing a Chinese counterfeit, you risk getting a device that does not meet these parameters.

Current and voltage

Standard power banks have a current rating of 5V. This is too little to charge a netbook, but ideal for a phone. Therefore, if you need to fully charge your computer, you will need an external battery with a voltage of 12 Volts or higher. What voltage to buy a power bank with depends on the specific parameters of the battery installed in the laptop. Therefore, in order not to make a mistake at the time of purchase, look at the characteristics of your device.

Important Some Power Bank models have a voltage setting switch. The numbers can vary from 16 to 19 Volts.

In standard portable batteries for phones, the current is 1A or 2A. This is not enough to charge a laptop. The parameter should start from 3A and above. For accuracy, you need to look at the characteristics of your laptop. If you decide to purchase a standard power bank with a minimum current, it will not be able to charge the laptop, or it will charge very slowly. You cannot work on a computer while charging this way, as the power bank will immediately turn off. It simply doesn't have enough power.

Capacity

When purchasing a portable battery, you should remember that netbooks have characteristics that are many times more powerful than smartphones. Therefore, the capacity of the power bank should be maximum. For example, if your laptop has a 10,000 mAh battery, buying a Power Bank with a smaller capacity is not advisable. The best option in this case would be to purchase an external battery with a capacity of 20,000 mAh.

If you see a Powerbank on the counter with a large capacity, but at a suspiciously low cost, do not fall for such tricks. As a rule, such devices have half the volume. It is better to purchase a battery from a proven and reliable manufacturer.

Universal connection

In order for a laptop power bank to charge other equipment, you need to buy a portable charger with special adapters. By choosing a powerful battery, you can charge your laptop and smartphone at the same time.

Connectors

Many users are wondering whether it is possible to charge a laptop from a power bank using a regular USB 2.0 or 3.0 cable? The answer is no! Such connectors provide voltage only up to 4.5 volts, which is normal for a phone, and negligible for a laptop. You will need a battery with a new 3.1 Type-C connector. Such a USB port is capable of transmitting an energy flow of 100 W. But this option does not guarantee full charging if you do not use the appropriate cable.

Often such cords are supplied with external batteries. But if not, you will have to buy it separately. Again, don't go for the cheap price. A good cord won't cost a penny. Therefore, to ensure powerful and fast charging for your device, purchase high-quality and original cables. A low-quality charging cable can even cause your laptop to burn out. The most reliable option is a portable battery with a standard round connector. Such a power bank will undoubtedly be able to charge your laptop.

Housing material

An important criterion, since the device must be shockproof and reliable. You should choose a model with protection from dust and moisture. Premium devices are produced in aluminum cases. They have an aesthetic design, high strength, smooth surface, and high cost.

The main advantages of the method

Advantages of pulse welding:

The first thing is the excellent quality of the weld. Let us immediately note that pulse devices are very expensive things. But they are worth it and will definitely pay off all costs in the future.
Pulse welds everything from steel to aluminum.
A minimum of additional tools and consumables are required.
No metal spattering.
There are no burns or failures of fusion.
Ability to control the arc.
Excellent ability to control the metal transfer process.
Economical consumption of materials, including welding wire and electrodes.
Easy seam cleaning at the end.
Easy to perform even for beginners.

Drawing of a pulse welding device.
Today, this method has only one competitor in popularity and efficiency - semi-automatic welding

It is characterized by high productivity and, importantly, process continuity

But a serious drawback is metal spattering, which results in the loss of up to 30% of the material. In addition to losses, these spatters must be cleaned after welding, which is very difficult and spoils the appearance of the weld. Pulse welding eliminates such a problem.

The main area of application of the method is the installation of pipelines of the most critical type, where the strength of the seam with a firmly formed back bead without finishing stripping is especially important.

This method has only two disadvantages:

it is not suitable for large welding areas;
serious cooling of the inductor is always necessary.

How to properly charge a laptop using a Power Bank

When purchasing a portable battery, you need to know how to charge it correctly. It is recommended that you read this information before purchasing.

The new battery must be fully charged. Otherwise, you will not be able to recharge your device.
The connection must be made through a special USB connector, and not through low-power ports. A cable with a round connector should come with the power bank.
If you have a USB cable and a 3.1 Type-C connector, you can charge your device using it.

Some models of power banks are equipped with a power button. Therefore, if nothing happens after connecting using the cable, you need to press the power button on the battery.

How long does charging take?

It all depends on the battery capacity and power. But on average, an external power supply can fully charge a computer in about 3 hours. Some models of Power Banks allow you to work on a laptop while charging. How long the resulting charge will last depends entirely on the characteristics of the computer.

It’s convenient to have an external battery when you’re on the road or far from a power outlet, but what to do if your laptop is being charged by a power bank? In this case, the devices are not compatible. Before buying a portable battery, you need to check the characteristics of the laptop and the Power Bank, and also read user reviews on the Internet. The problem may also arise if the power bank has low power. In this case, when connected to the PC, it will begin to charge itself.

Technique for charging a laptop using a power bank device

The connection principle is simple: select a plug suitable for the type and install it in the connector. At the same time, pay attention to the characteristics of the mobile gadget; it is important that its capacity is less than that of a power bank. In addition, when connecting, electrical parameters are taken into account: operating voltage and charging current of the external device. These values should match the computer's battery ratings.

Before connecting the laptop, you need to check the charge level of the external device.

When the computer battery capacity is small, you can connect such equipment to the battery, even if the latter’s charge level is reduced. This is due to the ability to repeatedly charge mobile equipment without recharging.

Models that are suitable for PC charging

If the above instructions seem like real gobbledygook to you, then you can simply purchase a charger that is guaranteed to work with your PC.

This list includes the following models:

EasyAcc Monster 26,000
HIPER RP15000
Defender Lavita 20000
Rombica NEO PRO180
Inter-Step PB240004U

As you can see, there are options, and they are not as few as you might think at first glance.

Characteristics

The main characteristic of the device that is worth paying attention to is the name of the manufacturer. Popular brands in this segment are PowerPlant, Drobak and Xiaomi, which produce powerful batteries that are suitable for any type of mobile electronics, including laptops

Popular brands in this segment are PowerPlant, Drobak and Xiaomi, which produce powerful batteries that are suitable for any type of mobile electronics, including laptops.

Little-known manufacturers are not as reliable, and their stated battery capacity may actually be lower.

The next point is the degree of protection of the external battery from dust, moisture and shock.

And, if impact resistance is not the most important characteristic, then preventing liquid and dust particles from getting inside can be called an important option. All functional models of well-known brands have such protection - not to such an extent that you can dive with them, but enough to be in a room with high humidity

All functional models of well-known brands have such protection - not to such an extent that you can dive with them, but enough to be in a room with high humidity.

Fully protected, including from falling, the external battery option can usually be recognized by the orange or dark red design of the case.

Rice. 3. Power bank with increased protection

Another quite important characteristic of the device is its capacity. The larger it is, the longer the laptop will work without recharging from the mains.

Batteries with minimal capacity are not suitable for use to extend the charge of a laptop. To do this, you should choose models with 20,000–30,000 mAh or more.

A capacity of 20 thousand mAh is already enough to increase the operating time of an average laptop PC by 3 times, 30 thousand is enough for a fivefold increase.

Although, if mobility plays the main role, you should pay attention to devices with a capacity of no more than 10,000 mAh - they are also quite productive, weigh no more than 200–300 g and fit in the pocket of a laptop bag. Advice: you shouldn’t chase a large capacity when looking for batteries with 40-50 thousand mAh - most often these are fakes with smaller parameters

Advice: you shouldn’t chase a large capacity when looking for batteries with 40-50 thousand mAh - most often these are fakes with smaller parameters.

An additional parameter that requires attention from female and youth users is the design of the device.

Often such equipment is not just made in the usual discreet color, but can have an original and eye-catching appearance.

Rice. 4. Stylish power banks from manufacturers Remax and Pyjy

When choosing a case material - plastic or metal - it is worth noting that modern plastic is often not much inferior in strength to aluminum.

Moreover, many new models of portable chargers are encased in a polymer shell, having no less wear resistance.

At the same time, they are more pleasant to the touch than metal options.

How to use for medical and cosmetic purposes?

It is used to whiten yellowed areas of the skin, such as the heels of the feet.
If you mix zest, sugar and olive oil, you get a natural scrub for the face and body. The scrub cleanses pores, exfoliates dead cells and normalizes oily skin.

Lemon has always been considered an anti-aging agent in cosmetic products. Vitamins and minerals, penetrating the skin, cleanse, nourish and tone it. Improves blood circulation, allowing the skin to be better saturated with oxygen. The skin becomes elastic, after the procedures it looks young and toned.

For skin

For dry skin on the heels and elbows, it is recommended to apply lemon peel once a day for 15 minutes; the procedure is recommended to be carried out 3 times a week until visible results are achieved.

Masks based on lemon peel are effective for combination and oily skin.

2 tbsp. Dried lemon peel should be ground in a coffee grinder and mixed with beaten egg white.
Apply the finished mixture to a clean face for 15-20 minutes and rinse with cool water.

Use regularly 2 times a week. This mask will tighten pores, dry out pimples and refresh your face.

For the body, lemon zest can be used to make a moisturizing scrub. To do this you will need:

100 g sugar;
1 lemon peel and 2-3 tbsp. olive oil.

A berry-fruit mixture will help strengthen the walls of blood vessels and the heart. To prepare you need to take:

1 lemon with peel;
cranberries – 200 gr;
seedless rose hips – 200 g;
honey – 200 gr.

The berries are passed through a meat grinder, honey is added to them, and everything is mixed. The mixture should be taken regularly for 1 month, 2 times a day, 1 teaspoon. Store in a cool, dark place. A mixture of lemon peel and honey in equal proportions (50 g) will help relieve spasms in the heart.

Reference! The mixture must be consumed fresh at times of exacerbation of spasms.

For gums

Lemon peel lotions will help strengthen your gums. It must be carefully cut, finely chopped and applied to the gum, leaving for 5-10 minutes. It is recommended to carry out the procedure 3-4 times a week.

The fight against excess weight is supported by consuming lemon zest in food. The peel is grated and added to meat, salads, fish and soups.

Peel the lemon peels and fill them with water.
Place on fire and boil for 5 minutes.
Cool the drink.

The tincture should be consumed in the morning 30 minutes before meals.

Equipment

Everything is very democratic here. The charger came dressed in a branded wrapper with Chinese characters on top of a plastic case. No extra box. Tearing open the wrapper, we find a transparent case with a device inside, a wire and brief instructions, again in Chinese. Special thanks to the seller from Ebay, who spared no pimply polyethylene on my parcel, thanks to which it arrived safe and sound. Obviously, the guy has already encountered the peculiarities of Russian customs and the valiant Russian Post.

The case, I must say, is not very convenient. It is held on top and bottom by word of honor and tape. It is not very convenient to constantly peel it off. Alternatively, you can leave it on one side, say, from the bottom, and peel it off from the top. It won’t open on its own, but it won’t hurt to tighten it with a rubber band.

Our thoughts on the quality of all accessories

USB Type-C is a public standard that does not require certification from Apple or any other entities to use.

That is why you need to be very careful with it, because if you connect something of poor quality through it, you can simply ruin the same MacBook.

For example, Apple generally recommends using only the supplied power adapter to charge it and insists that each USB Type-C cable must have a special serial number, which allows you to make sure that it is suitable for a particular laptop.

Official USB-C markings from Apple:

If the first three characters of the serial number are C4M or FL4, the cable is designed for use with the Apple 29W USB-C Power Adapter.
If the first three characters of the serial number are DLC or CTC, the cable is designed for use with the 61W or 87W Apple USB-C Power Adapter.

My personal practice shows that in addition to official Apple accessories, you can use USB Type-C cables from Native Union, Nomad and other manufacturers that are well-known by everyone without any problems.

In order not to harm your device, just do not use nameless Chinese accessories, which even look just disgusting.

And may you always be pleased with the autonomy of your MacBook. Good luck!
