The Price:

$40

The Verdict:

Affordable and useful.

The Uno is portable—a lot more portable than the original Fueltank, which charged two things simultaneously. The bonus of not having two is that you can actually pocket this one, if you're the kind of person who really needs to make sure your devices are powered.

Other than the fact that it's smaller, lighter and more discreet than the Fueltank, there isn't a whole lot of difference. We shoved a bunch of our gadgets into it and the Uno charged all of them fine. You even get 2 tips (an iPod one and a mini USB one) for free. The only downside is that it's give-or-take about half the capacity of the regular Fueltank, which isn't that much larger. It's just larger enough that you wouldn't want to pants it.

For $40, the Fultank Uno is a pretty cheap safety net for the times when you forget to charge your phone. [Callpod]

Compact enough to carry with you all the time

Uses Callpod's many tips, so you should be able to find one for your phone or device

Doesn't hold as much charge as its bigger brother, the Fueltank

This thing is amazing, but it's $200. It can support a laptop, three "small devices" (MP3 players, cellphones, Bluetooth headsets) and three USB devices at the same time. We don't know how it charges Macs, because Apple's Magsafe is proprietary, but we're finding out. This does seem like the best thing ever for working from the road. [Callpod]

All you have to do is download the 2PLEX software upgrade for your Dragon, install it, and you can hook up with any other Bluetooth headset to have a two-way conversation, or sync up so both of you can have a Skype call (via PC) or regular phone call (on a cellphone) with someone else. The software is $40, but if you have another Bluetooth headset already and don't want to buy another Callpod Dragon ($100) it's a decent alternative for BT walkie-talkie. [Dragon]

The Price: $70 online, but should be available at Best Buy for $60

The Verdict: Convenient. The Fueltank does exactly what it says it does: charge two devices simultaneously on the road. It's made even better because the charging tips are the same ones used in the Chargepod, so you can support just about every mobile gadget you have.

In our test, a completely empty Windows Mobile phone and a completely drained Callpod Dragon charged up to full in about three hours. After this, the Fueltank still had enough juice left to power the phone for another two hours. One quirk though, is that the battery status display only works correctly when the Fueltank isn't plugged in to a power source, and displays somewhere between half to full power when you activate it while it's charging via a wall socket. It works correctly when disengaged and powering other devices.

It's kinda similar to the Powergorilla that we tested last week, but only for smaller portable devices and not laptops. In our view, it's definitely worth $60 as a backup or extended battery, especially if you've got a phone like the T-Mobile G1 that can barely last a day on moderate use. The Fueltank is the same thickness and about 1.5x as wide as the G1, so it's easily slipped into your laptop bag. A good device for anyone who travels regularly and needs supplemental power where there's no outlets to be found. [Callpod]

Update: Ben Johnson tells us that even the tips supplied don't match the ones on the box. You get no generic USB or Samsung Blackjack, but you do get an iPhone connector (not 3G-compliant).

Our own tests at home found that the Phoenix was pretty solid in doing what it promises. Pairing the five included headsets was as easy as pairing one to your phone. You can then take the headsets and wander around your office (house) and be able to talk to any of the other headsets automatically. Muting and standby options are also available.

Of course, the main reason you'll be using this for (in businesses at least) is to make calls, and that works just fine. Same Callpod Dragon quality, just multiplied by five. The unit also comes with a car charger, a five-way Chargepod charger and a Drone, which is a Bluetooth dongle for your computer so you can pipe the conferencing through a Skype call.

Would we recommend this? Sure, if you're in one of the target markets listed above. If it's your business that's paying the $3000 price tag, what do you have to worry about? You'll get to listen and participate in conference meetings while going to the bathroom. Can you really put a price on that? Well, yes, and it's $3000. [Callpod]

It's also a Class 1 Bluetooth device, so you've got a theoretical range of 100 meters. Couple that with the Callpod Dragon and you've got a 100 meter headset setup that connects itself. Give it to your parents so you won't have to teach them over the phone how to connect a Bluetooth headset.

Check out Callpod's first ad spot for their Chargepod below. It's actually pretty neat and shows non-techies why it's useful for them.

The Price: $119.95

The Performance: Incoming sound was rich and full, but outgoing cellphone sound was only very slightly echoey. The effect we heard gave the listener the feeling that the caller was inside a room. Nothing dramatic, but it was noticeable. It stacked up quite well compared with our current favorite, the nXZEN nX6000, with comparable incoming and outgoing call quality. It's also just as comfortable, with both an in-canal earbud and a hook over the ear for security.

There's even a special Dragon to Dragon walkie-talkie mode that goes for around 100 meters (we got somewhere between 50 and 100, but it was through a wall) that sounds as good as a cellphone call. Might not be useful for you, but Callpod tells us Cirque du Soleil is using it to communicate with performers on stage.

The Verdict: If you've got a need to Bluetooth walkie-talkie yourself around the house while you're not using it as a headset, the Dragon can fit the bill quite nicely. The miniUSB charging port means you can charge it with the included AC adapter, car charger, or even the Chargepod adapter (nice touch) that it shipped with. Plus, Callpod's got a Phoenix conferencing system coming soon that can join five Dragons together and make calls over a cellphone or Skype. At a price of $119 (which means it's on par with the rest of the Bluetooth headset crowd), it's got great quality with future extendability. [Callpod]

After getting our hands on it and testing it out on just about every portable device we have, we've come to the conclusion that the Chargepod is the future of gadget charging.

That's a bold claim, but once you use it, you'll come to agree with us. See, with standard AC adapters, you'll be hard pressed to fit them all on one power strip because quite a few are large and oddly shaped. Then you'll have to get two power strips (or a power squid), which then means both of your outlets are now occupado. With Chargepod, you take up one outlet in one power strip and you're done.

Although the fanned-out orientation while charging makes it take up about a square foot's worth of surface area, it doesn't occupy all that much space when compared to individual chargers. Then there's just the coolness of (there are six blue LEDs that tell you when something's inserted) being able to charge all your stuff with the same device.

The basics of Chargepod are obvious from the picture. You have one center base station with a lead that plugs into the wall. Then you've got six interchangeable adapters that you can plug just about anything into.

As for the chargers, there's USB, miniUSB, BlackBerry, Motorola, Sony Ericsson (phones and Bluetooth headsets), Sanyo, Samsung phones, Samsung headsets, Qualcomm, Kyocera, Audiovox, LG, Toshiba, Pantech, Palm (Treo, LifeDrive, Tungsten), Nokia, DS, DS Lite, Game Boy Advance, Game Boy Micro, Nextel, Jabra, Sidekick, and various other phones I forgot to list. Essentially, it covers the whole spectrum of phones, headsets, and other gadgets.

Here's the downside: price. The base unit costs $49 and additional charger tips costs $9.95. This means that you'll have to buy at least five extra adapters (your first one's free) in order to fill up the entire body. That's over $100 to get yourself set up.

At this point, we can recommend Chargepod based on its convenience and ability to charge things as well as individual chargers, but if Callpod can get the price somewhere down to $39 for the base unit and $5 or $6 per adapter, then we can recommend this to everyone—even the cash strapped. – Jason Chen
