Need lots more power for your iPhone? This 1,900mAh power pack should keep it running all day.

Update: Looks like this is sold out already. You can find what looks to be an identical battery (in black) for $17.99 from HandHelditems--where you'll also find some very positive user reviews.

Until Apple sees fit to outfit iPhones and iPods with user-replaceable batteries (meaning never), travelers have no choice but to pack battery packs.

After all, the last thing you want in the middle of your playlist, movie, game, e-book, or audiobook is a dead battery. (It's not real convenient when you need to make a call, either.)

Meritline has a Mobile Power Station Battery for iPhone and iPod for $9.99. That's after applying coupon code MLC262362. Shipping is free.

What's the big deal about this particular battery? In a word: capacity. The Mobile Power Station packs a 1,900mAh lithium ion cell, which should power your device for--let's see, carry the one--ever.

OK, not forever, but a mighty long time. To put this in some perspective, the $10.99 iPhone battery pack I wrote up last April has an 800mAh battery. The $80 Energizer AP1500 I reviewed last month tops out at 1,200mAh.

Needless to say, a 1,900mAh battery should outlast them all. And for only 10 bucks! (I might just grab two.)

A couple caveats. First, Meritline ships from Hong Kong, so plan on waiting a good two weeks or so for delivery. Second, I've heard from several readers who aren't happy with Meritline's customer service, mostly because of lost or delayed shipments. I've never had a problem with them, but I wanted to pass along the concerns.

Of course, if you're looking for supplemental power because your iPhone barely lasts a day anymore, consider replacing its internal battery. That's something you can do yourself for as little as $6.

What do you think? Is this the battery deal of the century (hey, it's been a fairly short century), or does it sound too good to be true?

It seems Nikon has realized the Coolpix L100's lack of support for rechargeable NiMH batteries wasn't the greenest move (or maybe it was a secret plan all along). The digital camera manufacturer announced Tuesday an eventual firmware update to correct the situation.

I get the convenience of AA batteries in pocket cameras, but the L100 requires four of them and only supports alkaline and lithium-ion disposable batteries, approximately good for 350 and 900 shots, respectively. The NiMH option will get you around 600 shots before you need to charge up.

According to Nikon, the firmware update will be available in summer 2009, making this budget point-and-shoot megazoom a more attractive option. Of course, this doesn't improve its merely OK photo quality or the fact that you can't control ISO. But for some, that comes second to having a 15x zoom lens and AA batteries as a power source.

Being released simultaneously with the firmware update are a four pack of Nikon AA NiMH batteries (EN-MH2-B4) and a charger/battery combo set.

Unlike with the Xbox 360 and PlayStation 3, there aren't any first-party controller charging accessories readily available for the Nintendo Wii. At this point in the console's lifecycle, there are literally dozens of third-party devices that promise the most efficient and painless experience in getting your Wii remotes juiced.

There are plenty of variables to consider in picking out the best charging system. Price, charging style, and number of battery packs are all features you'll want to compare.

Lucky for you, we've put every Wii charger we could find through our vigorous testing procedures and have narrowed down a list of our favorites. Read through our top picks for the best Wii remote chargers and decide which is best for you.

Do you need power for your cell phone, MP3 player, digital camera, and other portable gadgets? Our friend Mr. Sun has an endless supply (well, not endless--5 billion years and kaput!). What you need is a way to harness those rays and turn them into energy you can use.

GoldenGadgets has just such a harness: the Portable Hybrid Solar Charger, currently on sale for $19.99--shipping will run you about $5.

What makes it a "hybrid" charger? Simple: It can draw energy from the sun (8-10 hours buys you a full charge--bad news for those of us who live in Michigan, where we're lucky to get 8-10 minutes of sun. Hey-oh!) or from a USB source like your PC, which does the job in about 4 hours.

The charger comes with a generous assortment of tips: BlackBerry, Motorola, Nokia, Mini-USB, USB, and iPod/iPhone. (Unless my eyes deceive me, there's also one for Palm, though the product listing doesn't mention it.)

Speaking of which, the product listing doesn't specifically mention iPhone 3G compatibility, either; however, one of the user reviews claims it works fine. (The demo video up top shows an iPhone getting charged, but it looks like a first-generation model.)

Sure, you can get an iPhone battery pack for as little as $6.99, but that powers one device and one device only. This eco-friendly charger can juice just about everything in your carry-on bag. Until someone invents a teeny little windmill, it'll have to do.

Extend your iPhone's runtime by nearly 70 percent.

Got power? Scratch that. Got enough power? Oh, who are we kidding, there's never enough. That's why no self-respecting iPhone owner should travel without an external power pack, a battery that clips on to provide extra juice just when you need it.

There are dozens of such products available, often with price tags in the $30 to 40 range. However, Meritline has an 800mAh external iPhone 3G battery pack for $10.99 shipped. (It normally sells for $35.99.)

The iPhone 3G Power Station plugs into the bottom of your handset to recharge the internal battery or supply emergency power. (My definition of "emergency" is a battery that dies halfway through your flight.)

How much extra runtime can you squeeze from the Power Station? Well, it's an 800mAh battery. Your iPhone 3G has an 1150mAh battery. Math isn't my strong suit, but I'm guessing you should get nearly 70 percent more runtime--not too shabby.

The Power Station recharges with a standard iPhone connector: USB cable, speaker dock, or whatever. According to the Meritline Web site, which is pretty light on details, it takes three hours to fully charge.

The only real downside here is that the Power Station "ships in 2-5 days via Hong Kong Air Mail," meaning it could take a full two weeks to arrive at your door. If you don't mind the wait, this looks like a mighty sweet deal on an iPhone battery pack.

You might balk at the $130 price tag, but this time more actually means better. The Logitech Cordless Desktop Wave Pro combo puts two of our favorite products together in one package: the Logitech Cordless Desktop Wave Keyboard and the Logitech MX 1100 Cordless laser mouse.

Both products received very high marks from their respective editors, and the MX1100 mouse even managed to win an Editors' Choice award. This time around, we're sticking to our guns and rewarding this winning combo as well.

One of the most significant hardware changes in the bundle that we don't speak much of in the review is the mouse's rechargeable battery. In our separate review of the MX1100, we weren't very happy to see that it used alkaline batteries for juice. We cut it some slack since it meant one less power adapter to throw into our mountain of cords, but Logitech really came through this time and includes a rechargeable battery with the system.

Logitech advertises two months of power per charge, and although we don't have the time or the resources to perform a drain test, we used the device for a full week and kept it on 24 hours a day and barely saw the drain indicator move. In our opinion, that's worth the bimonthly mouse charging.

The USB-powered Griffin iTrip Universal could be just the thing for broadcasting music around the home.

FM transmitters don't see a ton of traction on Crave, and for good reason. Strict regulations over broadcast power and frequency range have effectively stalled product innovation. The designs may change, but most of the new FM transmitters we see are just a rehash of last year's model.

Which is why we're happy to see Griffin's latest iTrip Universal, an FM transmitter with a rechargeable battery that uniquely aims to fill the void of FM transmitters designed for use beyond the car. Sure, the iTrip is as underpowered and interference-prone as any other FM transmitter, but if you're looking for a cheap way to route wireless audio the room, it's hard to beat the iTrip Universal's USB-powered design and $30 price.

Nyko has announced the release of an Xbox 360-compatible charging base, much like the PlayStation 3 one the company debuted almost two months ago.

The Nyko Charge Base 360 comes with two NiMH rechargeable batteries fitted with contact points that allow you to simply drop the controller into the included cradle. The base can charge one battery in 2 hours and two in 4. Nyko says that each full battery charge should net you about 25 hours of play time.

Microsoft offers a Quick Charge Kit for around $30 that only comes with one battery and charges a single pack in 3 hours.

The Nyko Charge Base 360 will retail for $35 and is available now. Check back with CNET in the coming weeks for a full review. A limited-edition black-and-gold version of the Charge Base will go on sale June 2.

The travel-friendly Targus operates cord-free (except when recharging)

If you're still using a corded mouse, it's time to get with the 21st century. One-deal-a-day site Yugster has a Targus wireless rodent for just $6.95, plus five bucks for shipping. It's a refurb with a 90-day warranty.

This three-button optical scroll mouse relies on RF technology (meaning no line of sight required) to communicate with its USB dongle. When the rechargeable battery gets low, you simply connect the mouse to the dongle using the included cable. You can, of course, continue using it while it's charging. There's also a USB extension cable so desktop users don't have to reach behind their PCs every time they want to plug and unplug the dongle.

Of course, this is really more of a travel mouse, one for notebook users whose machines lack built-in Bluetooth. (If yours has built-in Bluetooth, look for a Bluetooth mouse instead, one that doesn't require a full-time dongle.) At $11.95 shipped, it's a hard bargain to beat (it sells new for $29.95). Act fast: The offer expires at midnight today.
