5 high-capacity power banks that are great for the traveling techie

Given today's power-hungry phones and tablets, any power pack under 20,000mAh shouldn't be considered high-capacity. While the majority of these beefier backup batteries aren't suited for storing in your pocket, they're still compact enough to toss in a backpack, suitcase, or laptop bag for a quick charge when you need it. Check out these five power banks that provide enough battery to keep up with the most demanding tech-lover.

Note: When we state how many charges you can expect to get from each battery pack, we're using a hypothetical 2500mAh phone as our basis.

CHOETECH 20,000mAh Power Bank

Rocking dual-USB outputs — one dedicated to Quick Charge 2.0 speeds — this power bank from CHOETECH has a 20,000mAh capacity. What's more, it can charge off of either a Micro-USB cable or an Apple Lightning cable, giving flexibility to anyone dealing with multiple devices. Keeping you on top of how much charge is left are four LED lights on top next to the main power button.

The first USB output provides a steady 1-amp charge and even devices that don't have Quick Charge 2.0 technology can still utilize the second blue-coated output thanks its safe auto-detection feature. When topped off, you should get 6 to 7 charges off this power bank.

It has four blue charging LEDs on the front for easy checks on how much battery life remains in the PowerCore; and when you do need to recharge you can do it with the included Micro-USB cable.

EasyAcc Monster 26,000mAh Power Bank

If you're after more than just a pair outputs to keep your phones and tablets charged up, the EasyAcc Monster packs a 26,000mAh capacity and provides four USB ports as well as two Micro-USB inputs on the side that can work in tandem decrease recharge time up to 50%. With a total output of 4.8 amps, the more devices connected means a slower charge, but the overall convenience, functionality, and capacity outweigh reduced charging times.

Next to the USB outputs is a built-in LED flashlight that's handy for seeing in the dark, and on top are four tiny lights that indicate how much battery life remains in the power bank. EasyAcc has added plenty of safety features to prevent any damage to your connected devices, too. Capable of providing 9 to 10 charges, the EasyAcc Monster makes a great external battery to have on hand.
