Griffin TuneJuice Battery Charger Review the glory of the smartphones, how did we ever get anything done without them? To be perfectly honest I 5think my life was a lot more productive before smartphones came along. Here is the thing: when, in the past, did you ever have to charges your phone every single day?  And sometimes even twice! The inclusion of all this modern fancy fandangle technology in one product has been the bane of battery manufacturer’s existence. Well thankfully some companies took it upon themselves to give us a handy temporary fix until the battery info structure can catch back up with our modern technological devices.  Griffin has release one such products the Griffin TuneJuice Universal Charger has everything you need for on the fly quick charging when you just can’t make it to an outlet. Let’s get a look at it:

Specifications and Features:

Avoid the heartbreak of dead batteries. TuneJuice Universal uses three AA batteries to charge your MP3 player or other USB-charging device. Just pop the batteries into TuneJuice Universal’s sliding battery compartment, attach the charge/sync cable that came with your device and your device will charge. We’ve even included a fresh set of batteries to get you started.

A must-have for travel, camping or anywhere else you might face the bleak prospect of dead batteries.

  • Uses 3 AA batteries (included)
  • Output: 5 V @ 850 mA
  • Works with mobile phones, MP3 players and other devices that get their charge via USB cable
  • Adds up to 2.25 hours of talk time (on iPhone 3GS)
  • Uses the charge/sync cable that came with your device

Testing and Conclusion:

So how do you test a charger…Well I suppose you charge something. So I plugged in my iPhone and guess what happened? It started charging! Amazing, I know, but I suppose I should delve into it a little deeper. So once I completely exhausted the batteries that came with it I checked the charge. The 3AA batteries got me about 1/3rd of a charge which is nothing to shake a stick at. So I went with a cheap battery just to see how they perform and the consensuses this: cheap batteries do not work the constant bling noise that the iPhone makes will drive you nuts because the consistent voltage just isn’t their.This probably could be compensated with a simple pcb and some capacitors to regulate the power flow but this would take the price to a new level and really just go buy some better batteries you cheap (your choice of expletive here).

Now that being said the Griffin TuneJuice Universal isn’t the most portable option with companies like Mophie making the Juicepack and Juicepack air potability is hard to compete with. The Griffin TuneJuice Univeral is for the days when you are at school and you forgot to charge your iPhone, iPod Touch or whatever other device you should have charged and forgot your charger at home. Just pop on the Tune Juice in your back pack go to your first class and when you get back you’ll have dead batteries and enough juice to get you to the end of the day.

Overall it is a good design and a handy little device  for a very affordable price. If you are looking forsomething to stretch your batterylife just anough to get to the next full charge the Griffin TuneJuice Universal is a great option that I would reccomend to anyone not willing to drop the large chunk of change is costs for a Mophie JuicePack
