We&#;ve all been there. Your laptop's internal battery dies while handling some CPU-intensive workload away from home. There isn't any outlet in sight. So, you spend the remaining part of the day blaming yourself for not remembering to hit CTRL+S (Save).

The good news is that you can use an external power supply for a laptop to prevent those unwanted incidents. Whether you&#;re using your laptop in a café, on a plane, in a cab, or at your workplace, you can relax knowing you have that extra power.

That said, all external power solutions aren&#;t the same. Before buying one, you need to ensure that it has the power capacity for your needs and the right ports. Portability is also important. Read on as we discuss all the key features to look for in an external source of power.

What Is an External Power Supply?

An external power supply is simply a separate physical enclosure or device that can charge a laptop. It connects to your PC through removable or hard-wired electrical connection, cord, cable, or other wiring, while some models also allow wireless charging.

However, an external power supply isn&#;t just important for charging PCs. With its built-in AC outlet, it can also power other electronic devices, such as smartphones, tablets, video projectors, digital cameras, and baby monitors.

6 Features To Look for When Shopping for a Power Supply

Buying an external power supply for a PC can be challenging, considering there is a wide range of options in the market. To help you out, here're six key things to look out for when shopping for an external power supply.

Weight and Compact Design

Since you&#;re going to use your battery pack mainly outdoors, pay attention to its weight and overall design. In general, these devices are pretty compact. However, their sizes and weight may vary depending on battery capacity.

Bigger and heavier battery packs usually have higher charging capacity. The trick is to find a perfect balance between energy capacity and portability. Also, if you&#;re looking for a portable power pack to carry around in your laptop bag or backpack, go for a power solution that is compact enough to fit in the bag.

Voltage Output and Maximum Power Output

Voltage output is a measure of how much power the external power supply can provide at maximum. Typically, the higher the output is, the better. If your battery pack has a maximum output of 30 Watts and you are charging a laptop that receives up to 60 Watts, it will take twice as much time compared to using a battery pack that gives out 60 Watts.

When shopping around for an external power supply for a laptop, look for one with a voltage output of 60 Watts or more. That's enough dc power to charge most 13-inch notebooks. But if you're looking to charge a bigger laptop with a 15-inch display (or larger), go for a battery pack with an output voltage of 85 Watts and above.

Plenty of Ports

Pay attention to the number of output ports your external power supply has. You want to ensure there are enough ports to charge all your devices. Micro USB, USB-C, and lighting are the most popular ports on external power solutions.

If you're looking to charge multiple devices concurrently, consider a battery pack with several USB ports, including USB-A and USB-C ports.

Typically, USB-C Power Delivery (PD) Ports are the best for charging laptops because they can transmit much more power (up to 100 Watts) with compatible devices. In contrast, standard USB-C ports can only transmit 15 Watts, while USB-A can transmit 12 Watts. Hence, look for a USB external power supply that supports PD technology if you want fast and efficient laptop charging.

Warranty

If you're going to spend hundreds of dollars on an external power supply for a laptop, you want to be sure you are protected in case something goes wrong. Here are three types of warranties that manufacturers can offer you:

• Limited Warranty. This type of warranty covers the external power solution for a specific period from the purchase date. You'll need to keep your receipt safe to prove the purchase date.
• Limited Lifetime Warranty. This type of warranty covers the product for its reasonable life expectancy. This may vary depending on the manufacturer.
• Connected Equipment Warranty. This type of warranty covers the product as well as repair or replacement services for devices that are damaged while connected to it.

Overall, look for a manufacturer that offers at least a one-year warranty plus readily available customer support.

Wireless Charging

In , the number of wireless charging-capable smartphones crossed the one-billion mark. As more consumers embrace this cutting-edge charging technology, wireless charging power solutions are becoming increasingly popular.

One of the advantages of a wireless charging power solution is you no longer have to carry cables. If you&#;re one of those people that regularly misplace their charging cables, a wireless solution is the way to go. In addition, the charging ports remain free. So, you can do multiple things simultaneously while charging your smartphone, tablet, or other wireless-enabled devices.

Reliable Battery Life

Before buying an external power supply, ask for the battery life estimate. Chances are you will connect multiple devices, including laptops, smartphones, and cameras to your external power supply. Further, you may be someone who uses their laptop for demanding tasks such as gaming and streaming TV shows. Whichever the case, your laptop&#;s battery will be taking a hit, and you may need to draw power from the external power supply more often.

As such, you can expect your battery pack to generate a lot of heat. You need a product that has built-in tech to keep the high temperatures in check and protect the internal components from overheating. More importantly, the battery pack should be able to efficiently serve your needs for an extended period to provide good value for your money.

Learn IT | Tips for extending laptop battery life

When you get right down to it, battery life is the difference between having a healthy, truly portable laptop computer and having an ultralight desktop computer. If your battery can&#;t hold a charge, you will constantly have to plug into a power supply which cancels out the biggest benefits of a laptop &#; being able to use it just about anywhere. These tips to extend laptop battery life will help you get the most out of your machine.

As the graphic above states, your laptop&#;s charging port is a critically important piece of equipment. If you break the port, there&#;s no way to get power to your laptop. To minimize the risk of damage, don&#;t walk around with your laptop charger plugged into your laptop. If you accidentally drop your laptop and it falls on the charging plug, the resulting force could bend the plug, damage the charge port, or both. If you have small children, remember that they love to put things where they don&#;t belong. The last thing you want is for your child or grandchild to try to &#;fix&#; your laptop with a pretzel stick or crayon. The results could be disastrous

In addition to handling your laptop port with care, here are a few other steps we recommend to extend your laptop&#;s battery life and years to your laptop&#;s lifespan as well.

Plug your power cable into your laptop first, then the wall

These days, the risk of a damaging power surge is extremely unlikely but when it comes to the health of your laptop, it&#;s ALWAYS better to be safe than sorry. When you connect your charger to your laptop first, you minimize the risk of a power surge damaging the motherboard.

Once your laptop is fully charged, unplug your charger

The expression &#;use it or lose it&#; is a great way to remember when it comes to maximizing the battery life of your laptop. Think of your battery&#;s capacity like a tank of gas. When it&#;s fully charge, the tank is full. As you run your computer the &#;tank&#; starts to run dry. Here&#;s the difference. If you fill your car&#;s tank up after a few hours of driving, your car doesn&#;t know the difference. It just keeps going. When you start charging your computer after a few hours of use, the energy that is still in your battery, doesn&#;t have a chance to get used. That may not seem like a big deal but like a muscle that shrinks when you don&#;t exercise, your battery&#;s charging capacity shrinks when you don&#;t subject it to a full charging cycle. To give your battery a regular workout, we recommend unplugging it as soon as it&#;s fully charged and then following the next recommendation.

Follow the 20/80 charging rule

As we said above, in order to maintain peak performance, your laptop battery needs to &#;stretch its legs.&#; After you&#;ve unplugged your fully charged laptop from the charging source, wait until it reaches 20% of battery life before plugging back in. Your laptop should give you a warning when it reaches 20%. Otherwise, keep an eye on the icon at the bottom of your screen and plugin when it becomes a sliver or turns color. After you&#;ve reconnected your charger, keep it plugged in until your battery is 80% charged and then unplug the charger again. Following this cycle is like putting on your laptop on a short-rest workout regimen that builds long, lean muscles that last instead of big bulky ones that wear down quickly.

Close applications or programs when you&#;re not using them

We all do it. First, you open up your browser to check your and find a message with a presentation from a co-worker that automatically launches PowerPoint. After you read it, you open a new tab in your browser to check your Facebook and another to check Instagram. Then you open up a Word document to write the report you need to do. You realize you need some data from a spreadsheet so you open Excel and then another tab in your browser to do some fact-checking. In a few short minutes, you&#;ve created a lot of work for your laptop and it all impacts how long your battery will last. Check the tabs in your browser throughout the day and close the ones you no longer need.

Take care of your charger and cords

If your charger doesn&#;t work, neither does your laptop. Despite its rugged appearance, your charger is a delicate piece of equipment that can break easily. When you&#;re taking your laptop to school or work, resist the temptation to wrap the cords around the battery pack. This puts unnecessary pressure on the wires inside and could eventually cause the rubber casing to crack. It&#;s always best to unplug both wires from the charger, loosely coil them and store them in your laptop bag. You&#;ll also want to be sure you don&#;t leave your charging cables on the ground where they can get stepped on or damaged by a spilled beverage.
