XtremeMac InCharge Duo for iPad
August 1st, 2011This sleek dual charger has a small footprint.
The vertical form factor eliminates the need for dedicated desk space. You can charge two of any combination of recent iPads, iPods, or iPhones.
If you have a bevy of useful gadgets that all vie for the one or two front-and-center outlets near your workspace, the XtremeMac InCharge Duo for iPad may meet your needs. I like to charge all my devices at once, so having a multi-dock simultaneous charger alleviates the stress of hunting for plugs and more importantly, hunting for desktop real estate to use while the devices charge. I like the sleek design of the InCharge Duo charger for my Apple devices because it is has a small footprint and a vertical form factor that eliminates the need for dedicated desk space.
The charging station is a black plastic with two 30-pin docks for a variety of iPod family products. Measuring at 4.5" by 5.5" it is far smaller than the iPad and iPad 2 it charges and slightly larger than the iPod or iPhone. The rear dock has a support for the iPad and iPad 2 and charges at a 2.1 amperage level.
This dock can quickly be transformed into a second iPod or iPhone dock by simply lifting up on the outer corners of the rear plate and substituting the enclosed second iPod dock plate over the rear 30-pin dock connector. The two connectors have tailored dock adapters to help with stability and support for the product while it is docked. So I can charge two of any combination of recent iPads, iPods, or iPhones.
Charger and Second Dock Plate
What’s in the Box
Included with the InCharge Duo dual charging dock are one removable rear adapter to enable swapping between different iOS devices, an AC adapter, a
North American plug adapter (international plugs available), and 5 universal dock adapters labeled: iPhone 3G, iPhone 4, iPod Touch G2, iPod Classic, iPod Nano G5.
Using the InCharge Duo
The InCharge Duo is just a simple charging device. It does not have syncing capability, nor additional speakers and only a single cord to an outlet. Its small footprint means it also does not accommodate any devices with covers or cases while charging. Specifically, in the instance of the iPad or iPad 2, they must be au naturel. A skin might be OK, but I did not test it with a skin. If you use the open dock without a dock adapter, you can probably charge an iPod, iPad, and iPhone, with a slim case. It would be nice to have added functionality such as syncing or the ability to play music while charging, but the focus of this device is to solve the multi-device charging challenge and not to enhance the in-process usage.
A nice feature of the dock is the LED indicators at the front of the base to indicate battery charge status for each device. Orange means charging and green means fully charged; although it turned green at 95% for my iPad. None of my devices took longer than 3 hours to charge. The slowest to charge was the iPod photo whose battery was completely depleted. It took just under 3 hours. Both the iPads were less than an hour and the iPod touch was 1.5 hours.
Charges a Variety of iOS Devices
While there are 5 adapter plates, there are more iPod versions that are supported than is clearly stated. I tested the product with an iPad, iPad 2, an iPhone 3G, an iPod touch 1G, and an iPod photo. References in the Manual say that the charging station rear doc (2.1 amps) supports: iPod nano 1st, 2nd, 3rd, 4th, and 5th generations; iPod classic 160GB 2009; iPod touch 1st and 2nd generation; iPhone, iPhone 3G, iPhone 3GS, iPhone 4; iPad and iPad 2. Any 30-pin enabled device not mentioned here should be charged on the front 1.0 amp dock. I caution the user to gently place the device over the charging dock. I see how, when an adapter is not employed, that you risk forcing the connector on at an odd angle and damaging it.
XtremeMac will be 10 years old in October and produces a wealth of products dedicated to providing quality accessories that protect, power and play Apple devices. They are now an Imation company.
