As North Korea plots to blow us all to nuclear smithereens, the TechRadar reviews squad has been beavering away to get everything tested before the end arrives.

This week's hottest product has to be the Razer Edge, the first bona fide gaming tablet to hit the shelves. It's not cheap, but it's a one of a kind so we can see it doing well.

We've also tested the incredible molecule-splitting PowerTrekk phone charger which juices your gadgets using just gypsy magic and a thimble of Einstein's tears.

Check out these things and everything else we've reviewed in the last seven days…

Razer Edge review
Yep, the Razer Edge is probably the first device that can legitimately call itself a gaming tablet. You only have to look at it to realise it's built from the ground up with gaming in mind. We reviewed the Razer Edge Pro, which has an i7 Intel processor, 8GB of RAM, a 2GB Nvidia GT 640M LE and the option of a 128GB or 256GB solid state drive. So it's a serious device with serious components, then. It's very expensive at £1000/$1500 but it's hard to pick one up, play some Dirt 3 and not enjoy yourself. The Edge wins poinst for fun factor, style and proving that you can have Plants vs Zombiesand Left 4 Dead 2 on the same tablet.

You're lost in the jungle and your phone is out of battery so you can't navigate your way to safety. If you don't do something soon, you'll die. What you need is the PowerTrekk - a USB charger powered by water and the spirit of Albert Einstein. Anyone with an interest in tech and science will be fascinated by this gadget – it's absolutely not a product that most of us would find any use for, but the way it uses a hydrogen fuel cell to charge your phone using water as fuel is geeky gradious at it's most gratifying. Just remember to put a clothespeg on your nose – it makes an awful stink.

Dell XPS 10 reviewDell XPS 10 review
The Dell XPS 10's black plastic appearance and unnaturally heavy build make this Windows RT hybrod tablet an instant turn-off. While it may be for sale among its business offerings, that doesn't mean consumers should sacrifice a pleasing build or competitive portability. However, it still has to be said that is one of the finest Windows RT devices we've seen, and comes at an attractive price. The huge battery life is truly impressive, and it gives us hope that a concerted push from Microsoft could give Windows RT a future. However, it's certainly a secondary device that can only complement another full-form computer. If you're looking for a proper, singular upgrade, a full-fat Windows device is still your only option.

Huawei Ascend W1 reviewHuawei Ascend W1 review
It's had more leaks than a wicket canoe, but now the Ascend W1 is finally here and it's a thoroughly decent Windows Phone 8 handset.

The second screen era cometh with this slim LED TV's twin Freeview HD tuners, one of which can send a second TV channel straight to your tablet.
