The secret to not just surviving but thriving on business travel is to take care of both yourself and your equipment.

Just like we need adequate rest, food and hydration to enjoy traveling, our gear needs to stay charged. For AV pros who find themselves constantly on the go, there are plenty of options.

The Freedom is a second-generation smart handbag from Dutch company Phorce. Phorce’s first smart handbag was the Pro, and was specifically designed for business travel. The Freedom is smaller and more lightweight, and is designed for everyday use.

The Freedom incorporates a 15,000 mAh battery that is able to charge two devices (phone and tablet, for example) simultaneously for up to a week on a single charge. The internal battery can be recharged from any USB power source, eliminating the need for a wall charger.

Despite being over 25 percent lighter than the Pro, the Freedom claims the same premium quality and performance as well as enough power for demanding users. “Our goal has always been to make people truly mobile,” said Marijn Berk, founder of Phorce. “We started with Pro, a professional-grade product. Business travelers rave about it and they’re an especially tough crowd to please. We use modern design and technology to rethink what a bag can be and do. Our bags are as refined, intelligent and powerful as the devices you carry inside them.”

Phorce describes the Freedom’s design as “shape shifting.” It can configured into a backpack, messenger bag or briefcase, depending on the preferences of the user. It’s pockets are linked with microfiber, what Phorce dubs “display cleaning” to keep mobile electronics scuff and dust free.

Multiple pockets and the interior of the Freedom are able to accommodate documents, files and a laptop, while only weighing 3.5 pounds and coming in at 3 inches thick when unloaded. The Phorce sells for $199.

Taking a completely different tack, the Packr from solar power company Enerplex is a backpack that incorporates a patented flexible, durable 3-watt solar panel able to charge mobile devices. Enerplex claims that you can drop them, run them over with a car, and even get them wet and they will continue to function.

What makes the Packr solar panels flexible and durable are the CIGS (copper, iridium, gallium, selenide) solar technology that is used to make them. While most solar cells are placed on a glass substrate which makes the units heavy, rigid and breakable, CIGS cells can be mounted on a plastic backing. This allows the panels to be flexible, lightweight and rugged.

The Packr can charge a variety of USB-enabled devices, including tablets. Like all solar chargers, the more panels that are exposed to the sun, the more power the charger can provide.

It’s important to remember that the Packr is a direct solar charger. Lacking a battery it will not hold or collect power for later. Enerplex recommends connecting their Packr and other solar chargers to their family of lithium-ion portable batteries to collect a charge to power your devices for when you need them. While Packr’s can charge devices directly, that leaves you at the mercy of the availability of sunlight.

Enerplex describe the Packr as “water resistant” by which they mean that the panels are sealed in plastic and the USB ports have been waterproofed with rubber plugs, so they can be submerged in water and still work afterwards. However, the interior compartments aren’t waterproof. Just bear that in mind when carrying your gear around.

In addition, the Packr has 30-liter interior capacity (in other words, it’s a medium-sized backpack, and also features standard amenities like outboard water bottle holders, reflective stripes and a laptop pouch within the bag. It’s available in three styles, and sells for between $99 and $129.
