Hasta La Gadget!

Still weeping over the fact that your iPad won’t charge on that 2002 Latitude your company refuses to replace? Take heart, young buck. Scosche understands your frustrations, and it’s out to make coping somewhat easier with the Revive II dual-USB chargers. With one for the car and one for the home, you’ll most likely never, ever be in a location where your iPad can’t be juiced. In case you haven’t guessed, one of the USB ports on each charger is of the high-power variety, while the other will happily charge your iPhone, iPod or nearly any other USB-infused gadget that’s smaller than a 9.7-inch tablet PC. Both of ’em are up for pre-order now through the company’s website, though the $24.99 (car) and $29.99 (home) price tags do feel a touch steep.

Heads-up, iPad owners (or to-be owners, as it were) — the same devices you currently use to juice up your iPod touch or iPhone may not work on your fancy new tablet. Consumer Reports, TUAW and our own Chris Ziegler have confirmed that their powered USB hubs wouldn’t charge the iPad, and we’re even seeing reports that some Wintel rigs won’t either. The only sure bets right now are Apple computers and your nearby AC outlet, leaving iPad owners with fewer options when it comes to topping off that battery when away from your abode. We’re pretty certain this all boils down to the iPad requiring more power than most powered USB ports are designed to give, but it’s still something to keep in mind. So, any of you early adopters finding that your own powered USB hub or non-Mac does rejuvenate the iPad? Let us know in comments below.

Update: Macworld has a nice explaination of the whole situation. Looks like tablets just require more power to charge than smartphones — who woulda thunk it?

Update 2: And now Apple has come right out with a support article — head on over to see what it recommends.

Idapt’s new i4 is a charging dock for pretty much all of your gadgets. Like the company’s previous stations, the dock reduces cable-clutter, but this time it does it in shiny, piano-black style.

The hot-looking dock plugs into the mains and sits on your desk or night-stand. In the top are three virgin sockets, into which you can insert various “tips”. These are analogous to the dock inserts in Apple’s universal dock, only they also carry circuitry and connectors for various devices. If you have a vanilla USB-powered gadget, there’s a hole for that, too, hidden down at the side.

The tips fit most kinds of cellphone, the Nintendo DS, the PSP, the iPhone, all sizes of USB and one is even a charger for AA and AAA batteries. It even has an off-switch so you don’t have to yank the cord from the wall. The only problem might be the price. At $60, the i4 isn’t bad, but you’ll need to buy tips, either at around $15 each or in packs which start at $40 for 4.

The i4 also comes in white, available in May.

Huzzah! Yet another discovery for us to add to our ever-expanding list of “awesome things that’ll never actually happen!” Ibrahim Abou Hamad and colleagues from Mississippi State University have reportedly devised a method of charging batteries that could hasten the process rather significantly, and better still, it could provide “an increase in battery power densities” as well. The only problem? Lithium-ion batteries have been disappointing tech users for years, and so long as Energizer and Duracell are calling the shots, we kind of doubt a lot will be done to improve the longevity of ’em. Skepticism aside, the new method involves some fancy black magic surrounding molecular dynamics simulations, and researchers have found a way to boost charging time by “simulating the intercalation of lithium ions into the battery’s graphite anode.” We know we just went way over your heads on a Friday afternoon, but if techobabble’s your thing, all you can handle is right there in the Source link.

Ah, wireless power. One of those mythical mysteries that are far more likely to remain “something to strive for” rather than “the next big thing.” Oh sure, we’ve got Palm’s Touchstone and the Powermat, but until we can hang a 50-inch plasma from our bedroom ceiling and power it up without a single wire, we’ll remain firmly unsatisfied. Thankfully for those of us in that camp, MIT exists, and a few of the school’s best and brightest are toiling around the clock in order to develop a technology that would power not one, but multiple devices sans cabling. Thanks to the wonders of coupling resonance, we’re told that the “overall power transfer efficiency of the wireless system could be increased by powering multiple devices simultaneously, rather than each device individually.” In theory, the system could be implemented by “embedding a large copper coil in the wall or ceiling of a room,” but there’s obviously no set time frame for release. We’ll be looking for you geeks at CES next year, okay?
