The supposedly simple search for a usable USB power supply point at first but out to be not so easy. In the many favorable reviews, but also more expensive chargers to read horror stories of sizzling, buzzing, smoking, fire-breathing ... who has already looked around, knows. I chose the seemingly best-selling and rated best model to buy at a quite reasonable price and have to say that I am pleasantly surprised. It is not excessively hot during charging (hand hot), is very compact, the USB connector makes a durable impression (plugged Cable not wobble), and there is absolutely no noise. The connected load smartphones similar expeditiously as with the original enclosed power supplies manufacturer. I tested give it to a Nexus 4 and a Moto G. For compatibility with Apple devices I can therefore no information.
So I am in total satisfied with my purchase, even if the power supply nor his longevity has to prove.
