Otterbox Defender iON protects and charges your smartphone

The Otterbox Defender Series with iON Intelligence case claims to double the battery life of your iPhone

US accessories company Otterbox is well known for producing some of the best protective smartphone cases on the market. Its latest product, the Defender with iON Intelligence, combines a rugged case with a built-in battery and also works with a free battery extender app.

The Defender Series with iON Intelligence case (yes, it's really called this) claims to double the battery life of your smartphone. The initial iPhone version, which has been designed for the iPhone 4 and iPhone 4S, has a 1450mAh battery built-in. That's a bigger battery than the one that comes with both the iPhone 4 (1420mAh) and the iPhone 4S (1432mAh) so the claims of double the battery life are likely to be correct, at least from a technical perspective.

The key feature of the Defender with iON Intelligence case is the way it will charge your phone. There's a strip of LED lights at the bottom of the case which indicate how much battery power is left. The case will only ever start topping up your phone battery when it dips below a certain percentage. Unlike other battery cases, there's no need to switch it on.

The case itself will be part of Otterbox's Defender range. It has a triple-layer of protection consisting of a built-in screen protector, a polycarbonate shell and a silicon-skinned outer layer with port and plug covers that provide dirt and dust protection but not water resistance. The Defender range of cases add significant bulk to any smartphone but they are widely considered one of the best protective smartphone cases on the market.

The case has been designed to work with Otterbox's new iON Intelligence app, which is a free download in Apple's App Store and the Google Play Store. The battery usage app estimates and predicts battery power and battery time remaining by monitoring device usage habits.

The Defender Series with iON Intelligence case will initially be available for the iPhone 4 and the iPhone 4S. It is expected to eventually be available for the iPhone 5 and the Samsung Galaxy S III, with more devices likely to be supported at a later time.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

As a freelance writer who is always on the go, I like my technology to be both efficient and effective so I can do my job well. The HP OfficeJet Pro 8730 Inkjet Printer ticks all the boxes in terms of form factor, performance and user interface.

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
