Keeping one device charged on the road can be hard enough, but add one or two more gadgets to the mix and it's downright difficult. We recently showed you a backpack that can keep multiple gadgets charged, but it's not available until late this year and is expensive.

A better solution for many is an external battery that can charge up to three devices at a time, and that's the iWalk Extreme Trio.

The iWalk is a half-inch thin battery packing 10,000 mAh in a small form. It's designed to charge almost any mobile device (except laptops), which it accomplishes by having both an integrated lightning and microUSB plug. A full-sized USB port rounds out the offering.

The power bank doesn't just have the three different size plugs to connect devices, it can use them all at the same time. This permits charging iOS devices alongside Android (and other) gadgets. It doesn't just charge one after the other; the high output allows simultaneous charging of all three devices.

Many business travelers will carry a smartphone, tablet, and laptop to do everything needed on a trip. The iWalk can keep the phone and tablet charged, while leaving a port for another device. Professionals getting an Apple Watch can soon keep that charged alongside the other gear.
