The unit is extremely compact with less than 5 cm in the diagonal and 2 cm in height. He is a USB charger with a connecting cable (plug blades on both sides), and a kink to 2 * RCA adapter. That the device also has a built-in battery, I had not seen when ordering, positive if you want to use it on the go or even want to use, for example to a battery-operated radio. Still, I'd rather have resorted to power on the existing radio USB jack back, which worked without any problems.
The unit has its own switch and passes through the battery even when the power is off without problem, so you have to switch it manually in case of non-use, or the battery runs empty. The same applies to the switching which must be performed manually. Schön come on automatically when making the power supply would have been, however, the manufacturer recommends use during charging due to possible battery damage not, therefore the device will work as intended.
The connection to the device is working, either manually through the search for Bluetooth devices in the smartphone or automatically via NFC: Both worked fine for multiple devices, but can be connected to the EasyAcc only one other device. If you try to pair additional devices, so this will fail. Otherwise, there were no problems and the connection is securely held. I had recorded even after prolonged use no dropouts, even at a distance of approximately 9 meters of the TV. Even phonetically there was little interference and I could audibly hear no difference to play directly through a phone cable.
A word to the battery, even if it rather nice little bonus for me is:
The loading time is the manufacturer with half an hour (when using the 800mAh battery charger). When using the USB ports on Radiio it took a bit longer (about 45 minutes), but which is certainly explained by the presumably lower charging current. When standby time is 7 days, and the manufacturer as operating time for a period of 24 h. Verified I did this not because I use the device stationary with constant power supply connected.
Conclusion:
So I had imagined. The receiver does exactly what he should and thanks NFC pairing is super easy (but even without NFC usage easily doable). The connection stability is very good and a great impairment of the sound through the radio link, I can not hear. It is nice that the power supply not only the enclosed power supply special works via the USB socket of the radio and comes with the radio a Chinchadapter. The battery is a nice extra feature and possibly in the summer interesting when using a battery radios outdoors.
Because there really is nothing to complain about, 5 stars and a thoughtless recommendation.
