This battery pack certainly packs a punch.

The Wi-Stor Wizard could potentially be considered the mother of all battery packs as it acts as a Wi-Fi router, wireless storage platform, sharing medium and power bank.

The Wi-Stor isn’t particularly good-looking, nor is it lightweight, but it does have one very appealing feature — an 8,800mAh battery, capable of charging any tablet or smartphone from 0% to 100% in a matter of hours.

Prior to its unveiling back in March, the Samsung Galaxy S4 was one of the most anticipated smartphones of 2013. It has big boots to fill after following the hugely successful Galaxy S III, and to do that it’s been equipped with a new 5-inch 1080p display, a quad-core Snapdragon 600 processor, and an entire plethora of software features you won’t find anywhere else.

But is the Galaxy S4 worth the upgrade if you already have a Galaxy S III, and does this device have what it takes to stay one step ahead of its competitors? I’ve been using it for the past few weeks to find out.

Sony CEO Kaz Hirai has confirmed that its flagship Xperia Z will finally be available in the United States in the coming weeks. The device first launched in Europe, Asia, and other markets in early February, and it was the best-selling smartphone for six weeks straight in Japan.

The Samsung Galaxy S4 has dethroned the LG Optimus G to become Consumer Reports’ new top-rated smartphone.

It “delivered top-notch performance in the most critical areas of our tests, including the camera,” the report reads, before praising the handset’s display, and its “gesture- and sensor-based tools.”

As you may have noticed already, the embargo on the new Samsung Galaxy S4 was lifted today, and reviewers from all corners of the web are weighing in on the latest Android flagship. Given that the handset succeeds one of the most successful Android phones of all time, many of you are likely to be itching to find out what it’s like.

We’ve put together a review roundup to give you a snapshot of what those early reviews are saying about the Galaxy S4, and to help you decide whether the handset will be worth your hard-earned cash when it goes on sale in the coming weeks.
