In fact, I should buy another.

The Rayovac tip seems sturdier, But it's also longer and more likely to provide the leverage to damage the jack (and the DC(?)

This means that the battery takes much longer to charge than Apples adapter.

This product is wonderful. The reason why some of the other people have had a hard time with this adapter is that the powertip system sticks out a bit from the back of the Mac. If you are not careful with how you handle your laptop with the power connected - it can easily break the tip or the power connector to your Mac. The stock power connector has a very small head and it is rounded. The Kensington smartip system has what I would call a very "normal" type of connector. The downside to this mobile power freedom - is that you have to watch how the plug is resting on whatever surface you happen to be computing on.

Otherwise - great device, power my mac anywhere and charge my ipod to boot! Comes with the three tips listed in the tech details.

The tips are not poorly made and do their job as designed - just watch the connector !!

I bought this product a while back and the N23 tip broke inside my computer. I was able to retrieve it, and bought another whole unit while traveling. The tip also broke on this new unit and now I cannot find any replacement for the now infamous Smartip N23, not even at Kensington. Spent over $150.00 on these two units and they are now no more than paperweights. Mediocre quality and no customer support whatsoever. Back to Apple where at least their customer satisfaction is far superior.

This power adapter runs a lot cooler than the 45 watt adapter that Apple supplied with my G4 PowerBook and the PowerBook itself is cooler to the touch. Works great, either plugged into the wall or or my truck. Have not tried to use it on a plane yet because as far as I know, Southwest doesn't have power outlets on their seats. My only gripe is that the travel pouch could be a bit bigger; it's a snug fit getting stuff back in it, especially if you carry an iPod and a Palm SmartTip for it like I do.

I ordered this adapter because it was described as being for "Apple Notebooks". I couldn't find any more specific information on the product. When I received the product I found that it does not have a tip for a Macbook or Macbook Pro, nor does it supply adequate wattage to power these Apple notebooks that have been the standard for three plus years. I am very disappointed that the product information does not specify this, and that I lost ten dollars on return shipping. The seller, B & C Communications in New York, said he could exchange the Kensington for the right product. I wanted to buy a power converter to plug my Macbook into my d/c automobile power supply and explained that. He said he had what I needed, so I returned the Kensington and he said he'd take my return shipping costs off the balance due on the new product. Fortunately, before he sent the "power adapter" I asked him to email me all the specifics including the product number. What he was planning on selling me, upon return of the Kensington, was a standard Macbook power adapter! He didn't know the difference between this and the d/c converter I was asking for. When I told him that wasn't what I wanted and explained it further, he said he couldn't get the type of product I needed. He refunded my money and my original shipping cost, but said that Amazon doesn't allow him to refund my return shipping costs. Let the buyer beware! The seller was nice and helpful, but just doesn't know Macs. He also said that he had no control over the way Amazon described products and couldn't do anything about the misleading description. I then called Apple. They recommended Mac Mall online and told me of a good product that would suit my purpose. Always go to Apple first, and only use dealers who understand Apple products. There are Amazon affiliates that haven't a clue.

By T. Nash on June 19, 2009
I loved this product for more than a year - then the N23 tip broke off inside the power jack. It cost me $100 to have it removed, and another $75 for a new (Rayovac) power adapter. I blamed my teenage daughter for carelessness until I learned that this is a very common problem with the tip (and has cost many people much more in repair / recovery costs than my example.) After much reading, I am still unable to discern whether it's a problem with Kensington's tip, or Apple's jack. Both manufacturers are favorites of mine for both design and quality, so I can't help you there either. The Rayovac tip seems sturdier, But it's also longer and more likely to provide the leverage to damage the jack (and the DC(?) board inside).

Personally, I'll be limiting myself to using my G4 only while it's unplugged, and do my charging only when I can assure the connection is stationary and completely protected from bumps and jars - until i forget... or think i can get by just this once...
If I'm rigorously careful, I can save up for a newer laptop before it breaks again.

I needed a new power adapter for my Powerbook, so this seemed like a great idea. For for a little bit more than Apple's AC adapter I could get AC and DC with connections for auto and airplanes.

The only problem is, it doesn't work very well. The Smarttip connector for the Powerbook will not keep a connection. I continually have to check the power indicator on my Powerbook and twisting the connector to make sure the battery is being charged.

Kensington also seems to have fudged on the power specification. They claim 70 watts, but the Powerbook's System Profiler reports 45 watts. This means that the battery takes much longer to charge than Apples adapter. In fact, while I am using it, it barely charges at all. If I set the Powerbook down, likely as not the Smarttip loses its connection and I come back to a dead battery.

So, there's a great idea here. Perhaps someday, someone will implement it in a competent way.
