In the apparatus of EasyAcc it is not a device which is intended for the German market. Some of the inscriptions are in Chinese or English. There comes a direct suspicion that it's just cheap junk. However, I wanted the times even try. According to other reviews, the device should be good although the reviewers have been rated only the device and nothing else.
Processing:
The device is of width approximately as wide as a voice recorder that is nearly 60-70% narrower than the iPhone 4. The length in about 20% shorter than a Iphones 4 and is twice as thick. The device is only as good as plastic. On the top of the switch and status indicator is a piece of plexiglass / glass. However, the whole device made a very good impression. No manufacturing defects. No sharp edges where you could be injured. The inputs and outputs are marked with In and Out. The plastic has a piano lacquer coating and accordingly looks very classy and quality.
The weight of the battery pack is a little lighter than an iPhone 4. Therefore, it is no problem to keep it in your pocket. The compact design it is especially suitable when traveling.
Terms & functions:
The backup battery is in the charged state for the customer. After unpacking you can already start charging without charge it before. In the package is that the device must be disposed of and charged only once 3-5 times so that it can be used to full capacity. For battery type is mentioned neither in the instructions or on the packaging but I guess here's lithium-ion battery. The battery charge status can learn about the on and off switch. If you press the button once, the unit turns on and you can also see the LED's display the battery level. There are 4 LED's display. The staggering here in 25% increments. Whether that is exactly I can not say unfortunately. Since the device would have ran on the multimeter. To use the built-in flashlight pressing 2 times the button. To turn off simply holding down the button.
There are many different adapter here. For all common types of mobile you have an adapter. There are virtually all major manufacturers here. What is missing here is also HTC otherwise the Whole. In addition, other devices can be connected that can be charged via micro USB, USB or Mini 5Pin. The adapter can be easily exchanged here easily like a construction kit. When the average cable which connect the adapter and the device is broken without you lose it. Do you have to charge your device via the supplied cable.
The capacity is 5600mAh with loud packaging. So you could charge the iPhone 4 completely four times.
Although it is not intended for the German / European market. Here you get one more European power adapter to. (Noisy review of other members not so) you can the device via the USB slot on your computer to charge only one has the problem of output current from a USB port on the computer must not exceed 500mA. This means then for the backup system that it then takes longer until the battery is full again. It is best to just use the supplied adapter. This supports 1000mA. To recharge the battery already would have to bring a bit of time. It takes about 5-6 hours until the battery again has full power.
You also need have no fear that the battery discharges by itself. When no device on the battery depends on the battery itself off after few minutes of itself.
Conclusion:
I can only recommend the device each needs a battery backup system with a lot of capacity. I will contact you again when I have used the device a little longer to report how it looks with the long-term test.
Only so far I can with good conscience say that this is a very useful device.
5 stars ***** from me
Addendum 30.04.2012:
As promised I sign up again and reports from the long-term test. The battery had been about 80-90 cycles (more valued). The battery lasts as promised. Of course, as with all batteries that power softens a bit but it keeps itself in the context. What do I need to highlight is the low self-discharge. At low battery but also with expensive (Just Mobile Gum Plus) the battery is in a month usually almost empty. If not the. According to LED and also tested the battery still has around 80% of charge. It is highly recommended.
Addendum 05.06.2012:
The description is that it is also compatible with HTC. I do not know if HTC has its own cables or MicroUSB used. But a MicroUSB connector is definitely there.
