Scanning on the move is also now possible with a number of battery operated units available including the Doxie that have built-in memory and Wi-Fi allowing connection to any device. VuPoint Solutions also have a range of 'wand' scanners if you want a unit that is ultraportable.Charging a battery pack is a road warrior's first instinct, but what if you could generate your own power and really go off-grid? Renewable power in our context means solar.

Today there are a number of products that can offer a level of power security if you will be away from mains power for lengthy periods of time. Or if you want to do your bit to protect the environment, solar charging is the way to go.There are also a number of solar charging cases for your phone. Good examples include Juse, WakaWaka, and XD Design has a number of models to choose from including a compact unit that sticks to a window.

Folding solar panels have also been available for some years. SunJack is a good example, as is Powermonkey from Powertraveller. But if you want to get serious about generating your own power, the Expedition from Powertraveller is the ultimate in self-generating power sources, but it'll cost you about £450 (around $700, or AU$880).

Tylt Energi
With a built-in battery pack, this backpack from Tylt is ideal if you need to carry a load of power-hungry gadgets
When you need to carry a load of stuff and keep it all charged, the TyIt Energi backpack is ideal. Voltaic Systems have also been supplying backpacks with built-in solar panels for years.

In addition to the usual suspects, there are also a number of more exotic ways to generate power when on the move – the hydrogen fuel cell has been promised as a power source pretty much since the arrival of portable devices. But today this promise has been largely realised. The myFC is an ultraportable fuel cell that is designed to be as convenient as your smartphone. The MiniPak is also a handy unit. All you do to generate power is insert a Hydrostik hydrogen cartridge into the main unit to charge using USB.
There are two types of people in this world. The type that finds cloud computing good enough, and the kind that needs a whole lot more storage, connectivity, and power than the cloud can offer. The first type doesn’t need to bother much with docking stations. The second type rarely finds their laptop to be sufficient, and requires something extra.
Docking stations are designed to turn laptops into more viable desktop replacements – especially today’s smaller laptops that suffer from a dearth of storage space and ports. But these Ironman suits for your ultrabooks come in many varieties and styles: We’re here to help you find the best.

A replicator is not an unstoppable nanobot, but rather a port expander used for ultrabooks and more limited laptops. Essentially, a replicator copies the more popular ports from a desktop and grants them to laptops, too. This lets you always have a port for your mouse, keyboard, external hard drive, etc.
However, that’s all it does. There’s no boost to specs or other features, and connectivity options are limited. You may also run into performance constraints — for example, plugging a bunch of external hard drives in at once may lower the bandwidth available to each, since they’ll likely be sharing a connection to a single port. They may be cheaper, but they don’t have much functionality, especially in the days of Bluetooth.

Desk docking station
A full docking station is more likely to include battery charging, extra storage, and more port options (particularly when it comes to video options like HDMI or Ethernet connections). They are also more likely to have a literal dock where you insert your laptop. Think of it like a replicator, but with a lot more features that you would actually use.

Portable station
A portable station is a slimmed-down docking station design to be portable instead of just sitting at your desk. These are primarily designed for the more serious class of business traveler who really needs extra computing power and versatility at their destination. A portable station probably isn’t necessary unless you find yourself spending a long time working on projects away from your own desktop – but regular stations are becoming slimmer and more travel-friendly, so there’s some overlap here.

Display stand
A display stand provides the same features as a replicator or a docking station, but with extra physical support features. The stand typically includes an elevated platform for your laptop and perhaps a shelf for your keyboard as well. The goal is to make your station feel like a desktop while you are working on it. Some users will find this to be more ergonomic.
The market is filled with docking stations you can buy – some new, some old, some pricey, some discounted. What should you look for? Here are a few features that may make your search easier if you want the very support and options.

This Plugable model comes with support for Windows 10 and any other Windows system you may be using, a boon for professionals. It also has 6 USB connections, including both USB 2.0 and USB 3.0. An HDMI port is present with support for resolutions up to 2560 x 1440. It’s also on the small side, with a vertical design that means it cannot act as a cradle for your laptop, but it can function as a travel-sized dock if necessary. This is a good choice if you care about connectivity but don’t need a dock that acts as a stand.
These recommendations are by necessity laptop-agnostic. They’ll work with almost anything. But a lot of companies offer first-party docks built for specific laptops. These often fit better with the laptop’s style and design, and offer a wider variety of extra features. On the downside, they tend to be more expensive — expect to pay between $100 and $300. Lenovo, HP, and Microsoft are well known for building docks that compliment their devices.

Researchers at MIT and China’s technology-focused Tsinghua University have developed aluminium-based nanoparticles that could triple the capacity of lithium-ion batteries – the most common type of rechargeable battery, and one commonly used in consumer electronics such as laptop computers.

We've got one more significant point of differentiation to cover and that's stamina: The Toshiba Chromebook 2 does admirably well, with a quoted 8.5 hours of battery life per charge and real-world results generally ranging between 6.5 to 7 hours for me. The Dell Chromebook 13, meanwhile, is outstanding: It's listed for a whopping 12 hours of use per charge, and I've been clocking in somewhere between 10 and 12 hours total on most days.

Remember, too, that my usage tends to be unusually resource-intensive and heavy on multitasking, so if you're more prone to keeping just one or two tabs open at a time -- the way most people use a Chromebook -- you'll probably be able to stretch things out even longer. Even with demanding use, though, both systems provide respectable battery life, with the Dell taking the clear lead in terms of true all-day computing.

I should also mention that each laptop uses its own proprietary charger, which may be a bummer to anyone hoping to move toward the up-and-coming universal USB Type-C standard. Thus far, the 2015 Pixel is the only Chromebook to feature such a connection.
