1. Charge Your Laptop Using a Power Bank – Much like how you’d charge your smartphone via a power bank when there’s no other way to recharge it, you can also use a power bank to charge your laptop. 
power bank is a great choice to charge up your Apple, Dell, Lenovo, or another laptop, as it outputs approximately 20 volts of power. Also, you’ll save a few bucks by consulting our roundup of the, As a rule of thumb, avoid power banks that put out only 5V, as most laptops need 8V-12V power. 
If you can’t manage a power bank, your car’s battery can charge your notebook without a charger, but you’ll need a, An accessory like the outputs up to 300 watts—more than enough to power a laptop! Although you’ll need to leave the power inverter somewhere on the vehicle floor, you can still take your laptop inside and out—which is excellent for beginners. 
Of course, these things must be plugged into power vs. being a power source by itself, like a power bank. (or your favorite brand) would recharge your laptop the same as a power bank. Choose a charger with the right mix of USB ports to support all your devices.
USB-C has a smaller oval-shaped connector that’s reversible and designed to conduct much more power at higher speeds than the older USB-A port. This makes it an excellent alternative for charging your computer when you don’t have a charger. Furthermore, power adapters compatible with the USB Power Delivery protocol (USB PD) feature protections against overcharging, overheating, etc.
As such, they’re among the safest methods to charge via USB-C. There are plenty of different chargers out there. To help you choose the right one, see our roundup of the, While it’s great to know that there’s another option to charge your laptop battery without needing the official charger, you’ll probably end up with a dead or failed battery if you set the voltage too high when using a universal power adapter. 
It usually comes with interchangeable tips, with many different brands supported. Some battery packs even work with your car’s 12-volt cigarette lighter, making them truly portable. Super batteries are like second or spare batteries for your laptop. They have different charging cables, and they replace your original laptop battery. 
Unlike super batteries, these are regular batteries that don’t require different charging cables. A spare battery is a life-saver for those times when your laptop’s battery has run out, and none of the alternative charging methods are currently available.
You can connect your laptop via a cable to another computer’s USB-C port to recharge its battery. USB-A ports won’t work, so be sure to plug the laptop into the computer’s USB-C port. However, you should note that if the charger or charging port cannot provide the required voltage, the laptop will charge slower than usual.
This is normal and nothing to worry about. An external battery charger enables you to recharge your laptop’s battery when it won’t charge due to a faulty motherboard or DC socket. 
Provided your computer has a user-removable battery, take it out and mount it on your external charger. Connect the charger to power and wait until the flashlights indicate the process is finished, then reinstall the battery in your laptop. That’s it—you’re good to go! Pick an external battery charger specifically made for your machine. 
Many smartphone brands like Samsung and some tablets like iPads support reverse charging, meaning they act like USB power banks. On Android, you may need to enable this capability in settings. Otherwise, connect your laptop to the tablet’s USB-C port to give it a quick battery boost when you need it most.
However, you should limit reverse charging to emergencies to avoid overheating the battery in your phone or tablet, which can shorten its lifespan. If the voltage and power don’t match the specifications of your laptop’s original charger, it may be unsafe to use different charging methods. The official charger or its approved replacement is the best way to safely power your laptop in all scenarios.
Another common question we previously covered is, “” Unfortunately, there is no easy answer: Does leaving your laptop plugged in ruin the battery? Yes, it does. But then so does charging it every day.Curiously, the industry as a whole doesn’t seem to have settled on a single answer for the question about whether to use your laptop on AC or battery power.
Most manufacturers advise against leaving your laptop plugged in at all times. Some of the above methods can be unsafe for your laptop battery’s longevity, so avoid using them regularly unless urgent. Always use the official charger with your laptop; resort to these methods only when necessary. To avoid interruptions in your work, it’s smart to invest in an external power adapter or a USB-C charger and always carry a spare battery.
Forgetting your charger at home is annoying! Next time when packing your bags, throw your chargers in before thinking about everything else. : 5 Ways to Charge Your Laptop Without a Charger

Can 5V charge a laptop?
Why am I not able to use a USB-A port to charge my laptop? – T he short answer: The voltage and power that standard USB (called USB-A) ports support are not powerful enough for laptops. To elaborate on this topic, there are a few key things to keep in mind:
1. Voltage and Power 2. Power Output and Limitations of USB-A Ports 3. Power Required By Laptops The Wrap-up
Most of our devices are designed to recharge using a specific voltage to prevent damage to the device. The easiest way to figure out the voltage used by your device is by simply referring to the information printed on the original charger that was included with your purchase.
You will want to look for the power output of the charger, which is typically in the format, “_V/_A”, A simple comparison would be automobiles and the type of fuel they require to operate. If you have a sedan that requires regular unleaded gasoline, filling the tank with diesel fuel wouldn’t be compatible.
Our devices and the voltages they require to recharge are very similar to this. If you own a device that requires a 15V current to recharge, a 5V or 20V current would not be compatible. With this being said, we also have to pay attention to the amount of power required by our devices.
While some chargers may list the power output in watts (W), other chargers may not. The good news is that it’s very simple to figure this out. Once you have located the power output, simply multiply the voltage (V) by the amperage (A) to determine the watts (W). Example: 5V/2A (5 x 2) = 10W ; 20V/2.25A (20 x 2.25) = 45W Example: 5V/2A is the same as (5 x 2) = 10W ; 20V/2.25A is the same as (20 x 2.25) = 45W USB-A is the most common type of USB port.
These ports can be found on most standard chargers that are included when you purchase small portable devices, such as a phone or tablet. However, all USB-A ports are not created equally. A large majority of USB-A ports only support a 5V current, which is fine for charging small devices, but not quite powerful enough for large devices.
- Depending upon the device, the included charger may support up to 12W (5V/2.4A).
- If you have a new USB charger, you may notice that the inside of one or more of the USB-A ports have a color, which typically indicates that it supports a “fast charging” technology.
- Sometimes, these USB-A ports can support 5V, 9V and 12V currents, up to a total of 18W, which allows compatible devices to charge more rapidly.
It is also worthy to note that it is extremely rare for a USB-A port to support amperages exceeding 3A or 18W, whichever is the greater. Due to this, even the most powerful USB-A chargers will only support 5V/3A (15W), 9V/2A (18W) and 12V/1.5A (18W). Some USB-A cables may also limit the amperage due to the internal wires or the type of connector on the opposite end of the cable, so be sure to use a compatible cable for your device and charger.
- The voltage and power required to recharge a laptop will vary drastically amongst various computers.
- Sometimes, this will even vary amongst the same laptop models due to having a more powerful processor or graphics card, so it’s always best to look at your original charger that was included with the device.
A large majority of laptops recharge using currents between 15V and 20V, and require power upwards of 36W. As you can see, the voltage and power required to recharge a laptop are drastically higher than what a USB-A port can provide, which causes this compatibility issue for charging.
While there may be a few small laptops that can recharge at lower voltages and/or currents, these computers are not very common and would still recharge at a much slower speed. We hope that this is helpful as you look for portable charging solutions for your laptop. If you have any questions or need some assistance, feel free to reach out to our team of experts! At J-Go Tech, we focus on developing innovation charging solutions that primarily support USB-C charging.
As USB-C charging becomes a standard way of charging, we understand that there will be many opportunities for people to charge their devices faster, easier and with less equipment. With this, we are on a mission to educate consumers on the advantages on USB-C charging technology.

Can you power USB from HDMI?
Can you buy a USB-C monitor? – At this moment, as I write this in early 2020, there aren’t a lot of monitors that take advantage of this standard. There’s still a lot of work to be done here. HDMI has been the standard for monitors for over a decade and it’s going to stay for quite a while longer.
- Because HDMI can’t carry power, any monitor with an HDMI connection is going to need a separate power connector.
- This means if you want to have the monitor powered over USB-C, you would need two pathways for power.
- This would raise the price of the monitor.
- You would also need to make sure the computer’s power supply was robust enough to supply the monitor.
Gaming PCs and laptops have big power supplies, but smaller and older laptops don’t. It’s going to take some time to build computers that are designed to do this sort of thing.
Will USB to HDMI work on laptop?
What Is a USB to HDMI Adapter? – As the name suggests, a USB to HDMI adapter allows you to output your screen to an external display, such as a monitor, HDTV, or projector. It consists of a USB plug at one end, and it connects to the laptop or desktop that you want to project.
The adapter also has an HDMI port on the other side, so you can plug it into an HDMI cable that is connected to the external display. Generally, USB to HDMI adapters has plug-and-play functionality, which means that you don’t need an external driver to get them to work. Since laptops or desktops usually have two or more USB ports, you won’t have any trouble extending your display.
Using a USB to HDMI adapter, you can also mirror your display on another screen. Most USB to HDMI adapters have one HDMI port, but if you need a dual or multiple display setup, you can look for ones that have two or four HDMI ports.
Why does my laptop have 2 USB-C?
If you use 2 USB C ports then one port could be used for data while the other is used for DP Alt mode video. Two ports would allow an effectively ‘full speed’ USB 3 connection at the same time as a dedicated display from the GPU.
What is the use of C port in laptop?
What is USB Type-C? – USB Type-C is a smaller, reversible USB connector that can transmit data, video, audio, and data (USB 3.1) as well as provide charging power to many devices (USB power delivery or PD).
