Of course, benchmarks won’t help in testing these devices and we resorted to practical use. After all, all that matters is whether they do a good job and how quickly they do it.
We tested both devices in identical scenarios and compared the results. As you would expect, the first test was how quickly they get charged up. Both devices stayed true to their specs, although the 5,5Whrs charged up somewhat quicker, a bit less than 2 hours. The 10 Whrs version required slightly more than 3 hours.
Our main testing was with HTC Hero Smartphone, which has a 1350 mAh battery.
Power Fort 10 Whrs managed to fully charge the HTC Hero in 2 hours and 20 minutes, which is only 5 minutes less than we managed by charging the phone via a laptop. Fully charging the device via a wall outlet takes about 2 hours.
Power Fort 5,5 Whrs turned out to be a slower charger as it took 4 hours to charge up the HTC Hero. Just to make sure, we tried it two more times and received identical results.
We tested out the Power Fort devices with several other Smartphones, an MP3 player and Samsung’s camera. All these devices are powered via USB port so everything was set for Power Fort devices.
