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.
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.
Most people can find use for a USB power bank (also called an external battery pack, backup battery, or portable charger) to keep phones and other devices charged while on the go. Rather than tracking down a wall outlet, owning a USB power bank allows you to enjoy a conveniently portable (albeit limited) power supply.
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.
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 is a measure of how much power the external power supply can provide at maximum. Typically, the higher the output is, the better.
Watching your phone or tablet steadily run out of power when you're nowhere near an outlet is stressful. But there's an easy solution: a portable battery or power bank. These are available in many sizes and capacities, and can include lots of handy features like fast charging and multiple ports.
