Griffin Power Block review for Griffin P/N: 9772-PWRBLKW
The Griffin Power Block carries a retail price of approximately the same as Apple's A/C to USB charging adapter, but if you look around you will find the Power Block available for much less than the retail price. I will have to admit that I considered buying Apple's charging adapter because of its extremely compact size (about the same dimensions as a child's wooden playing block), but I decided to buy the Griffin Power Block since it comes with an iPod data-sync cable. This cable is not just for charging up iPods, but is a fully functional data cable. Many modern devices are powered by the +5 VDC regulated through the USB bus, so the Griffin's AC adapter can also act as a fully functional charger for devices such as GPS units or competing media players.
I evaluated the Power Block using a 2nd generation iPod shuffle, iPod Touch, and a Tom Tom One XL GPS unit. The Griffin Power Block is a rapid charger but I did not detect exorbitant amounts of heat generated from either the AC adapter or the device. I used another Griffin FM transmitter that doubles as a USB charging point for use in a car (+12 VDC) and that unit got extremely warm during charging. This Griffin Power Block stayed relatively cool. It charged up the shuffle, Touch, and Tom Tom without any drama or problems, BUT the charging LED remained RED throughout the charging cycle if you insert the AC adapter upside down in a standard AC outlet. Even when the iPod shuffle, iPod Touch, and Tom Tom all reported a full charge, the Griffin LED remained red. When I flipped it around so the polarity of the prongs matched the polarity of the outlet (kind of confusing since it is advertised as having non-polarized plugs) the LED turned green upon completion of charge using the iPod Touch. With the 2nd generation iPod Shuffle, it continued to burn "RED" while the shuffle's own LED indicated a full charge. This was in accordance with the instructions included with the Griffin Power Block.
The Griffin AC adapter is compatible with 120 VAC and 240 VAC systems, so you can take it with you on your international travels without worrying about compatibility with foreign outlets. The two prongs fold away, giving the AC adapter a compact profile that is easy to store in your pocket or bag. The prongs are supposedly non-polarized, so you can plug it "upside down" in an outlet without having to mess around with finding the correct orientation, but that will cause the LED to remain RED even after the device is charged.
Pros: For the same price of an official Apple adapter, you get an extra data cable. The adapter is light, sleek, and versatile.
Cons: It is slightly larger than the new pint-sized Apple charger.
Overall: It works as advertised and was compatible with every USB device I tried. I give it 4.5 out of 5 stars.
Computer-free charging, works as expected 2008-07-07
I bought the Griffin PowerBlock AC Wall Charger for use with my iPod Touch. I resisted buying Apple's own wall charger because I felt it was a bit overpriced at $30. While the Griffin PowerBlock is the same price, at least you get a spare USB-to-dock cable as an extra bonus.
I've been using it for a couple of weeks now, and no problems. It's nice to be able to plug the iPod into a power outlet overnight and wake up the next morning to find a fully-charged unit. I have a notebook computer as my home computer, and I'd rather not keep it on 24/7 just to keep an iPod juiced up.
Also used it on my slightly-older iPod Video, works fine for charging that too. I'm guessing it'll work with just about any dock-input iPod/iPhone without any issues.
Only one minor shortcoming: The display light on the PowerBlock is supposed to stay red while charging, and turn green once charging is complete. In practice, when the iPod gets close (but not quite all the way) to full-charge, the light switches between red and green every couple of minutes, basically giving you a false-positive. Not the most reliable indicator, although it does turn a solid green once charging is fully done. (I suppose you could also check the iPod itself to confirm when it's done.)
Perfect For All iPod's and All MP3 Players!!!

This is the best wall charger you could ask for if you are buying any mp3 player or buying an ipod this is for you okay all you do is simple plug it in into a wall outlet use the included cable plug it in your ipod and their you go the light on it will be red which means its charging and then it will turn green once its done charging, if the cable included dosent work if you dont have an ipod then use the cable with the other mp3 player great buy, buy it today!
