A Good Portable Powerbank Lets You Keep Your Devices Fully Charged

For many of us, the world travels on a charging cord. With a portable power bank, you can move easily from office to your favorite workspace and never drop a word or a piece of text as you type. There are many options available for charging the devices you need most. Many also come with the cables necessary to hook up all of your electronic gear. To keep your phone, tablet and laptop working effectively no matter where you go, investing in a portable power bank is a terrific option. These portable power banks also offer plenty of data on what's pulling power and how much each item is taking, so you have a good estimate of your remaining time away from the nearest outlet. Many of the powerbanks noted below offer either a solar charging port or a built-in solar panel for best results with the smallest environmental impact. Take your working life outside and enjoy some free power with your fresh air!

1 - Omni 20+ 20000mah Laptop Power Bank

The Omni 20+ offers multiple ways to charge many different items that you need to stay connected. From the AC plug for your laptop to the USB plug for your phone or tablet, you can stay mobile and free of outlet restrictions for hours with this small but powerful charger. It's less than 6 inches square and just over 1 inch tall. It's about a pound and a half, so if you're planning on some serious backpacking, be ready for the extra weight. You can charge your Omni 20+ from a 50 watt solar panel or a standard wall outlet, and it will provide flow-through power while it's hooked up.

2 - Sikon AC Outlet Portable Laptop Power Bank

Students the world over would benefit from a Sikon Portable Charger. This useful tool is just over 8 inches long and only three inches square, yet it offers an AC plug, a flashlight, a USB port, a C plug, a micro plug, and a fan to dissipate heat. When using this incredibly versatile charger, make sure to monitor the power button; once you turn it on to power up on the AC plug, it stays on and will use up the battery even after you unplug your laptop. This charger tops out at 100 watts, so confirm that the items you need to charge will work with that limitation before you buy.

3 - Voltaic Systems OffGrid 10 Watt Rapid Solar Backpack Charger

If you love the great outdoors, this is the backpack for you and your gear. Not only will this backpack charge all of your USB items while you hike and sight-see, but you can charge many other portable power banks that allow flow-through charging. While this backpack doesn't offer an AC plug, you can charge up a power bank that does. This backpack is extremely well-structured and offers users 18 inches of height, 12 inches of width and 8 inches of depth in which to store all the gear you need to take your hobbies and profession on the road. Because this pack rides a bit lower, it's easy to turn it around and secure your gear with a bit more certainty when traveling in the city.

4 - SunJack 25W Portable Solar Panel Charger

If you've already got a pack you love, consider investing in the SunJack portable panel for your work and fun outings. This pack features three folding solar panels that can be hooked to your existing travel gear. While you hike or visit your favorite city, your attached solar panels will be powering up the 20 watt batteries so you can charge your USB items overnight. This panel is shock and waterproof, though the batteries are not, so be sure to fold it up and put it away during bad weather. You can get this unit with either two panels or four, depending on the wattage you need. Because it offers USB charging, it can be used to power up other power banks that offer an AC plug.
