Is it possible to charge a laptop without it's charger? Yes, and the easiest way to do it is with a universal adapter. Remember to always check the voltage, no matter the charging solution. If that doesn't suit you, charge your laptop from a car battery or use an external battery charger.

no. Here's why: the USB ports on laptops function to dispense power to other devices and peripherals, which is why you can charge your iPad, iPod, and other devices by simply plugging them in. This means that any battery pack or power solution meant for your laptop needs to be plugged into the power port.
Not all Dell laptop chargers will work on all Dell laptops, because the individual models vary in power source requirements. The chargers, while paired with compatible models, are designed to work with all laptops that use the same type of connection and require the same power output.
USB-C is a universal charging standard. That means that, technically, it doesn't matter what USB-C charger you use, it should be able to power up a laptop with a USB-C charging port and power bank. Today the majority of laptop USB-C chargers are interchangeable, but it's not guaranteed.
Simply plug the cord in the USB port of the phone and the laptop. USB options will then show up on your phone screen. Select the first option which says "supply power to the other connected device". You will now notice that your laptop has started charging.
Using a charger with too low current rating might fry the power supply, but not the laptop. As the difference in voltage in this case is small, it should be OK. But using a charger with too high current won't damage your laptop. Using a charger with too low current rating might fry the power supply, but not the laptop.
You can see the model label of the notebook in the lower right corner of the screen or in the upper left corner of the keyboard. You can often see a series of letters and numbers. 2) Serial number: This is the identity number of the notebook.
Look at the identification label on the side of your AC adapter. Write down the total number of volts and the total amperage the AC adapter uses. If these numbers are not listed on the side of the AC adapter, they will be listed in the manual that came with the device that uses the AC adapter.
There are two parameters required to find out the pin size in connector for a power adapter. The first is the outer diameter of the pin and the second one is the inner diameter of the pin. Both are measured in mm and you can measure it with the help of a good precision scale.
Look on the bottom of the laptop sometimes under the battery for the Volts and Amps. Look on the AC adaptors for the Volts and Amps. Just match them.

Given the almost unprecedented success of the Toshiba Satellite range of laptops, the demand for the Toshiba ac adapter has increased dramatically. There are two mainstream Toshiba AC Adapters that are being sold for use with the Toshiba series of laptops – one is rated 19v 3.95a and the other is 19v 4.74a.
On Laptops the Model and Serial number can be found on the bottom case of the Laptop as either a printed sticker or laser etched into the cover as shown below.
Check the voltage and current rating. Every universal laptop charger lists the voltages and current that it supports. As long as it's under 90, you're safe to use a universal charger. Remember, very few laptops require more than 90 watts with the exception of desktop replacement notebooks.
Using a charger with the wrong voltage rating can potentially damage your laptop. This is typically caused by too high voltage. But using a charger with too high current won't damage your laptop. Using a charger with too low current rating might fry the power supply, but not the laptop.
The battery life can go down considerably if you use a lower voltage laptop charger. An incorrect laptop charger can damage your motherboard – On many occasions, faulty laptop power supply has caused irreparable electrical damage to laptops. It usually happens when you rely on a duplicate or universal charger.
Voltage: 19.5V and 19V is a relatively small voltage difference. It is most probably safe to use as long as: The current of the charger is the same or higher than that of the laptop. Laptops usually don't draw the full power from the charger even when in use and being charged at the same time.
If your laptop has a built-in USB-C port, then you'll be able to charge your laptop via a USB-C cable - you just have to make sure the cable has a plug adapter (the box-shaped plug at the end of your phone charger than can plug into an outlet). Some laptops, in fact, use a USB-C cable as the primary charger.
Yes, you can draw 45W of output power from a 90W power supply if output voltage and polarities of the connectors are the same, as what the rest of the answers indicated. But bear in mind that the Overcurrent protection limit of a 90W power supply is higher than the overcurrent protection limit of a 45W power supply.
never do this please, the 90W adapter has a dfferent plug connector with the 65W adapter, if the original power adapter is 90W, never use a 65W one, but if your laptop uses a 65W power adapter, you can use a 90W power adapter to replace it
Yes, normally you can interchange AC adapters, but HP and Dell power bricks aren't just simple AC adapters. They have a little bit of extra circuitry in them so the laptop can tell if you're mixing brands. There's an extra pin in the center of the plug that this circuitry uses.
Universally designed to charge and power a variety of laptop computers, this widely compatible universal laptop adapter includes interchangeable power tips for most laptops that are made by Acer, Compaq, Dell, Gateway, HP, LG, Lenovo, Sony, Toshiba and MSI.
As well as delivering data, USB Type-C is designed to power all of our gadgets and not just the portable ones. The connector is rated to deliver and receive up to 100W of power, making it suitable to charge laptops and more.
Of course you can. If the phone supports USB Power Delivery protocol, the phone and charger will mutually agree on a voltage both can support to optimize charging speed. If not, then the charger will likely select 5V and 0.5A, 0.9A or 1.5A, giving the phone a reasonable but not super-speedy charge.
You can charge your Pixel (2015) using a phone, tablet, or other laptop with a USB Type-C port, if the other device supports two-way charging: If your Chromebook is plugged into a power adapter, unplug it. Your Chromebook will begin to charge from the other device.
Today the majority of laptop USB-C chargers are interchangeable, but it's not guaranteed. Some laptops come with USB-C ports that don't charge. However, in some cases, we've run into laptops that can charge over USB-C even when they have a separate power jack.
That USB cables that came with your phone may plug into your tablet's interchangeable charger, but that USB cable will limit the current to between 1 and 1.5 amps. So, many devices will actually use up the same (or more) charge than the USB port can supply, never charging the battery at all.
Yes, assuming you didn't “cheap out” on the adapter, charger, or cable. For example, you should be able to use a charger with a USB-C connector with an adapter to an iPhone, or Micro-USB connector just fine.
USB-C is a universal charging standard. That means that, technically, it doesn't matter what USB-C charger you use, it should be able to power up a laptop with a USB-C charging port and power bank. Today the majority of laptop USB-C chargers are interchangeable, but it's not guaranteed.
Absolutely. If your laptop has a USB-C port, you can almost certainly charge it with it. The same goes for your phone, and any other compatible USB-C device.
Plus, not all laptops have a universal USB-C charging-port. The needed power-cables are included in the package, laptops can be charged with up to 65 W. Of course, the Lenovo power bank also allows users to charge their Smartphones with two regular USB-A ports.
