For our performance testing I wanted to run both in-lab and on the trail tests. As I do not own a MacBook I did have to borrow one for my tests. The book I borrowed was the MacBook Pro 15.4-Inch Unibody. According to HyperDrive's website the HyperMac MBP-222 should be able to provide 27.2 hours of continuous power. I also used my iPhone 3G S as a secondary device and the one I would most commonly bring with me on the trail.
My testing was as follows;In Lab - Continuous Power
Here I simply plugged in the device and used it as I normally would. This included writing a few articles. editing images in Photoshop , web browsing and e-mail use.
iPhone continuous testing was the same but the phone was set to play music through the iPod interface throughout the test.
Interestingly my battery life time with the HyperMac was quite a bit less than stated on the HyperDrive website. The website says 27.2 hours while all I saw was 20 hours of power under the usage I listed above. This included a couple of 2 hour naps for me while the MacBook was either uploading or downloading information over a wireless network.
Now while a seven hour difference sounds bad, it is not really as many standard battery tests reduce overall power consumption by dimming the display, and turning off other items. In fact HyperDrive's site says;"The wireless productivity test measures battery life by wirelessly browsing various websites and editing text in a word processing document with display brightness set to 50% on a MacBook with a Better Battery Life setting
The settings I used prevented the MacBook from dimming the display, was set for high performance and would not turn off the display until it had been inactive for more than 4 hours. So in all a 20 hour run time is excellent.
I gave up on the iPhone test after it ran for about 36 hours. Simply put the HyperMac MBP-222 could probably power your iPhone for a few days without dying.In Lab - Recharge
This test was to see how long the HyperMac could keep each device running if there was no power available. I would typically plug the iPhone and the MacBook in as soon as they hit 20% battery life remaining.
Here we see something very interesting - using the HyperMac as a recharger only I was able to use the MacBook Pro for a total of five days. This is using it during normal hours, not on an extended bender or marathon session. The iPhone was able to be powered for more than 45 days without ever plugging it into a computer or power outlet. On the Trail
The tests on the trail were all about longevity. The trip that was planned was for two days. While we would have power, I would not be using it for the two main connectivity devices I was carrying and also just for fun my Canon Digital Rebel XTi. For these three items I would only use the HyperMac.
Over the course of the two day trip the HyperMac performed very well. The MacBook was not only used for work it was also the only source of entertainment over the two days. I would plug the MacBook into the HyperMac and was able to watch DVDs or AVi movie files.
The HyperMac also had no issues maintaining the charge on my iPhone 3G S and keeping the Canon batteries charged. I was not able to test it on the trail for more than two days at the time of writing but I do have a hike of the FootHills Trail in South Carolina early next year, and look forward to testing out the HyperMac on a longer duration trip.
