EMTEC Power Connect Review (Page 3 of 4)

Page 3 - Test Results

Out of the box, the EMTEC Power Connect had some charge, as I could immediately power this on. To optimize the performance of the battery for first use, I charged the battery, drained the battery all the way down, and then fully recharged it without interruption. Once this initial charge/discharge cycle was completed, I unplugged it and put it through our tests. I pulled out my two devices previously featured in past reviews, an HTC One X+ and ASUS Nexus 7 (2012). Each were plugged in, and I recorded the results with a battery tracking application. For the HTC One X+, I charged it from 0 to 100%, as the internal battery is approximately 2100 mAh, and can be charged by the EMTEC Power Connect at least two times, theoretically. As for the Nexus 7, I charged this from 50% to 100%. I compared the results with the ADATA PV100 Power Bank. Just to note, the ADATA PV100 is rated at delivering up to 2.1A @ 5V. For both of these devices, I also compared the charging times with stock chargers.


Unsurprisingly, the results for the HTC One X+ are quite similar. You might wonder why, especially since the ADATA PV100 can deliver 2.1A. However, you should know current is pulled and not pushed, so the current actually drawn by the smart device is dependent not on the charger, but on the device itself. Thus, we can see the variance in time is negligible, with a difference of about eight minutes. On the other hand, both of these are quite a bit slower than the wall charger, which charged up my phone in a little more than half the time in comparison to the portable chargers. On the Nexus 7, the results were a bit closer, but I should restate this is only the time to charge from 50% to 100%. As you can see, the charging times was slower for the EMTEC Power Connect. It was approximately 15 minutes slower than the ADATA PV100 Power Bank, and approximately half an hour slower than a wall charger. This might not be a huge difference, but considering this could extrapolate into an hour or more of difference compared to plugging the tablet into the wall, it would have been nice to see EMTEC make provisions for both 1A and 2.1A charging.
