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 AC (Alternating Current) 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 extra iPod data-sync cable. This cable is not just for charging the batteries of all iPods, but is a fully functional data cable that you can use to sync your iPods. Many modern portable 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 (Firmware 1.1.5), 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 generated a ferocious amount of heat during charging. The Griffin Power Block stays relatively cool throughout the charging process. It charged up the shuffle, Touch, and Tom Tom without any drama or problems. In fact, the Griffin Power Block is even capable of fully charging up a 2nd generation iPod shuffle. The LEDs on the Shuffle and Power Block will turn GREEN once the Shuffle is fully charged, indicating the Griffin has some type of smart charging circuitry.

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.

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, and doesn't carry the Apple branding or logo.

Overall: It works as advertised and was compatible with every USB device I tried. I give it 4.5 out of 5 stars!

4.0 out of 5 stars Computer-free charging, works as expected, July 7, 2008

By	C. Tsiokos "Costa" (New York) - See all my reviews (REAL NAME)

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.)
