Am I the only one who gets really irritated when a new gadget requires you to change its batteries? To me, there's little worse than the constant cycle of having to track down new batteries every time it runs out a juice. Apple's Magic Trackpads are a great example of this.
Mobee has a possible solution to this small (but nonetheless grating) issue. If it works as promised, The Power Bar battery pack means that those of you who may use a Magic Trackpad won't have to find two working AA batteries, or wait for the a battery charger to do its work. Instead, The Power Bar connects to a USB port, so you can still use your trackpad while the battery pack makes use of your PC's power.
The Power Bar appears to be simple to install: According to Mobee, it slots in where you would normally put the AA batteries. The pack uses a micro USB cable, which attaches to a port on the pack that you slide into the Magic Trackpad's battery compartment. Plug it into your computer when the power runs out, and in six hours your Magic Trackpad will be fully charged again. A full charge should last around 10 days, and the pack can manage approximately 500 cycles before it needs to be replaced.
Other than the cycle rate, the only downside is that the slot to connect the pack and USB does stick out a little from the trackpad, but this is insignificant to the overall usefulness of the device.
At $38 (€30), it's not a particularly large investment to try out--plus the amount of batteries you replace would cost more in the long-term. You can find out where to pick one up once it is available on the Mobee website.
