Customer Reviews

This is a great dual port car charger.

Unlike a lot of dual USB chargers out there, it puts out a good 5v 2A current out of the top jack, and an above average 5v 1A current out of the bottom jack.

If you use a car dock (especially the Google/HTC Nexus One Car Dock) you can charge your phone and run your dock with a regular high quality Micro USB 2 cable. This saves a lot of headache if you are using a single Car DC jack for multiple devices. So, you can run a GPS Android Phone Dock, along with a standard iPod/iPhone USB 2 cable with no extra adapters or dongles. Mega space savings and clutter prevention.

The charger juts out about 1 1/2 inches from your standard sized DC jack surface. I can see why they needed to do this versus making it more flush to the car panel. The thing gets warm with full load and needs the extra space. I believe they made the Powerbolt Duo as small as they could for the price.

Speaking of price, this adapter uses high quality plastics and seems more expensive than its MSRP price. Although the metal contact pieces are not of a high conductivity metal, I expect that it would not corrode even with the occasional car style beverage spills and drips. The 30-pin Dock cable that comes with the unit is the standard Kensington iPod cable quality. The cable itself is flimsier, but it's reinforced where it counts. Apple cables usually become separated where the cable jacket meets the connector. The included Kensington cable will probably last a few months longer with heavy use because of its reinforced areas.

Here are my experiences:

2A Jack:

Fast Charge Barnes ; Noble Nook

Fast Charge Nexus One (and probably all HTC devices)

Fast Charge and safely run Nexus One Car Dock using standard HTC or other premium Micro USB 2 cable

Fast Charge iPhone 4

Fast Charge iPad

Standard Charge iPhone/iPod (all)

1A Jack

Standard charge all devices, but not enough current to fast charge or run dock + phone combo by itself.

The only way this could be better if it were smaller, and both ports were 2A.

I highly recommend this adapter to all roadwarriors and mobile device users!

UPDATE August 2011:

I am updating this review to give you an idea of the adapter longevity. I originally wrote this review in late 2010. It is now late-mid 2011 and the adapter is still running well. It has survived a soda spill with subsequent alcohol bath to clean it.

The Kensington 30-pin dock that I used it with has continued to serve its purpose well, unlike it's mate, an OEM (you know the fruit) cable that broke within 3 months.

I reiterate my positive review and I highly suggest purchasing this adapter.

New items tested working well with Adapter:

-Motorola Atrix Car Dock (2.1A ; 1A)

-HP TouchPad (2.1A ; 1A)

I second the other five-star reviews. This device outputs the power it states from both ports, and, consequently, can charge anything up to and including the iPad and iPad 2. It also runs cool even under load; it's a very well-engineered piece of gear.

Critically for Ford owners and other car owners whose cigarette lighter jacks are powered even when the ignition is off, this device has VERY low standby power draw. While this is not listed in the specs on the box, I asked Kensington tech support for the draw when the charger is plugged in but nothing is charging from either of the USB ports. The response: "We are sorry for the delay in the responce. We would like to inform you that the product(K33497US) draws approxmitely 5mA in stand by mode."

(I had another iPad charger that would drain my car battery in a few days when left plugged in but with nothing charging. The Kensington seems not to have the same problem.)

In short, of all the high-powered car chargers out there for iPads and similar devices, this is the one to get.
