How to charge a laptop without a charger. Taking care of his room, he found an old laptop he hadn't used in years, left, and without locating its charger. Therefore, they have decided to give it a new life (perhaps it is used as a "media center" to connect on TV or as a computer to exchange files over the network), but He is fully aware that, without his precious charger, it does not. It will be able to supply power to work (or to charge the battery still installed on the laptop).
If this is exactly the situation you are in, you should not be afraid to throw away the newly recovered laptop: On the following lines, in fact, I will show you by wire and signal how to charge the laptop without the charger.
To be successful in this purpose, it is sufficient to obtain information about the laptop power supply: I can guarantee that once you do, it will be very easy to replace the original charger in the proper way, at least Fewer select two very valid solutions: a compatible charger or external power supply source, such as a power bank, and extremely low cost.
I managed to make you happy and now you cannot wait to understand how to achieve the goal you have set for yourself. You couldn't have given me better news! So, without hesitation, make yourself comfortable and read carefully the advice I will give you during this guide: You will see, you will be able to understand how you can solve your problem in a few minutes. At this point, I have nothing left to do, but wish them a good read and, why not, good luck!
How to charge a laptop without a charger. First: identify voltage and amperage
Before you understand how to charge a laptop that actually misses a charger, you need to get information about voltage (electrical voltage capable of operating the device in question) and in amperage (laptop battery And the amount of current device compatible with hardware can handle correctly).
This approach can cause a fault to be very dangerous and cause a catastrophic short circuit, which can damage the computer, blow up the electrical system, or even worse, cause physical harm to those who operate the laptop May - so pay too much. Pay attention to what you'll read next, and if you're not sure what to do, ask for a more expert opinion as well.
Generally, voltage and amperage information is clearly indicated on the original laptop charger, however, they can also be retrieved from stickers affixed to the bottom of the computer, including the MAC address and information. Serial number, or label of the battery attached to the device (assuming you still have it available).
Once the tag has been identified, check the voltage and amperage needed to power the computer/battery: Generally, on a notebook computer, voltage fluctuations can occur at 15V to 24V direct current, While the amperage can fluctuate between 3A y 5A (based on laptop power).
The time you must choose, as I will explain later in this guide, make sure that the output voltage is the same as indicated on the laptop (to avoid overload problems) and that the amperage projection is at least equal to that of the laptop. Pointed at - a compatible 3A charger is also good for charging 5A laptops. While you should not connect the charger less than the charger required by the laptop, as it causes serious damage to you, the power supply burns out (which in this case should generate a greater amount of power) to power the device properly).
Also, you should pay full attention to the type of input voltage (or input) compatible with the charging device you are going to select, verifying that the latter is also compatible with the power network: is equal to the reference value Supports 100-240V (low alternating current or AC ) and dual power frequency, which is 50-60 Hz; The incoming amperage, on the other hand, is generally determined to be 2A. Make sure of these figures, as they may vary depending on the country you are in.
Identify the appropriate additive.
Now that you have the necessary information about the required voltage and ampere, you should consider one last important detail: A. Power connector type compatible with your laptop.
Typically, the dedicated power supply enclosure is located in one of the laptop's side covers: FYI, not all "plugs" are the same, but each manufacturer has a different connector (with specific length and thickness) and differs from the same manufacturer. -It is not uncommon to find separate laptop power connectors.
When choosing, make sure that the charging device does not have a single connector (for example, dedicated to a specific laptop model): Fortunately, most compatible chargers include almost all of the available "plugs", placing it at the end of the charging cable. Can be installed easily.
Regarding the Apple laptop, for example, the case is slightly different: there are three specific types of connectors available for the new MacBook (including the Air and Pro), which we describe below.
- On MacBooks produced from 2009 to 2012, it is possible to find the connector "L" MagSafe ;
- Produced between 2012 and 2015, you can call the "T" connector MagSafe 2 ;
- Or on a MacBook produced from 2016, it is possible to find the connector USB type c.
How to charge a laptop without a charger
Once the principal part of this guide runs out, it's time to take action and explain how to charge a laptop without a charger: In practice, you can choose to buy a power bank rechargeable, laptop included battery. Useful to supply power to or is equipped with a compatible power supply, both to be used for recharge operations and to supply power directly to the computer from the electrical network.
External Battery / Powerbank
If you want to use an external battery (power bank) to charge a computer's battery, you should consider purchasing a device with enough amperes to provide the power needed for charging operations.
Personally, I suggest you opt for a device that has more than one or more capacity of 20,000 mAh so that even the largest laptop battery can be easily recharged.
Also, pay attention to the connector park included in the sales package: You'll find yourself using the power bank to recharge the laptop's battery, therefore, the mere presence of a "classic" USB cable is somewhat limited.
Therefore, please carefully read the features of the product in question and ensure that the various power connectors used with laptops are present (for example) for MagSafe older Macs, with interchangeable bolt "common" laptops and/or connectors. For USB Type C for modern laptops).
Personally, I do not recommend using power bank power when you need extremely high computing power: because it is a power source with limited capacity, in fact, it can dry quickly, and when you are at least Expect this to be "dry". So if you intend to use the laptop for long or demanding sessions from the point of view of energy expenditure, I suggest that you opt for the purchase of a compatible power supply.
Compatible power supply
If you intend to power the laptop (or want to recharge the battery) then you can directly rely on the mains compatible power supply, which is the charging device, the supplied connector, and special adapters for the transformer. Thanks to, can adapt to the voltage/amperage required by different types of laptop computers and does so in complete safety.
In any case, always pay attention to the requested and supplied power information and when I follow the advice given in the previous section.
Finally, before proceeding with the purchase, make sure that the power supply you choose is equipped with the correct connector required by your computer ("plug", USB Type-C, or MagSafe). Here are some products that you can use to replace "standard" power supplies that you, unfortunately, don't have now.
In general, using these power supplies is extremely simple: all you have to do is identify the most suitable connector for your laptop, connect it to the end of the power cable, and use the device exactly as You will do the original. As an Apple laptop, to avoid damage and unwanted surprises during power-ups, I recommend you buy a cable and charger directly.
Along with the computer, did you also get an old cell phone, and in this case also this charger is missing? So I really think that's what I need from you: search my website for my guide on how to charge your mobile phone without a charger, in fact, I fully explained how in case of such an incident Be treated.
