“What is a power bank?”
you ask. The answer? A portable battery with two purposes: to keep your devices charged and to give you peace of mind. The best power banks feature high-capacity batteries that can charge your typical smartphone up to 5 times and are capable of charging multiple devices at once. These days they’re more affordable than ever, and some even serve as solar chargers, which means they can be powered by the sun for eco-friendly use in between charges.
Whether you’re a long-time user of portable power banks or have never used one before, you may be wondering why people use them. Specifically, what makes a portable power bank so special and why would it be helpful for your lifestyle?
The answer is straightforward: convenience. With the right portable power bank at hand, you won’t have to search endlessly for an outlet to charge your phone/tablet/laptop/camera whenever they run low on battery life. It’s especially handy when you’re constantly traveling or on the go — whether it’s for work or play. You can even keep one in your car in case of emergencies!
To charge your power bank, plug the micro USB cable that came with your power bank into the power bank and then plug the other end into a USB wall adapter or computer USB port. Alternatively, use one of the chargers that come with most smartphones to charge your power bank.
If you have a solar power bank, you can also charge it by placing it in sunlight. The amount of sunlight you need to fully charge a solar charger depends on the size of your solar charger and the number of watts delivered by its panels.
Power banks are pretty self-explanatory, but a digital power display may be a bit of a mystery. Here’s what it does:* Displays battery life in real-time as a percentage.* Shows the current capacity and expected runtime of the device.* Compensates for weather conditions and temperature to give you an accurate expectation of how much battery remains.* Indicates the status of my solar panel recharging, if applicable. Depending on the model, it can also tell you the voltage input or output, in addition to providing information about mAh (milliampere-hours) and your device’s charging speed.
If you’re like most of us, you want your power banks to be easy to carry and use—and the best ones are designed for this. They look great, too: sleek and compact. The best makers don’t skimp on features . . . or battery capacity.
The Xtension Power Bank is one of the smallest available but has a generous 2200mAh capacity plus two Qualcomm Quick Charge 3.0 USB charging ports that can charge phones at speeds up to 50% faster than standard chargers. This stylish little guy fits almost anywhere: in a back pocket, backpack, or purse since it’s small enough to travel with and light enough not to weigh down other items in your bag.
