Yes, the price is justified and profitable. Why? This battery charger no cost materials are processed. Everything is built dibasic. Installation button, the USB sockets and the LED chain makes a good impression. The charging electronics used is equipped with a fast and iSmart technology. From me a strong buy recommendation.
Now to the individual:
The Power Bank comes in a simple and practical cardboard packing into the house. This of course is the Power Bank, a Quick Start Guide in several languages, and a Micro USB - Cable. The USB cable is suitable for charging the Power Bank as well as for the material to be loaded Smartfon or tablet. My delivery was a ribbon USB - Micro Cable settled. The cable length is approximately 65 cm long and in my opinion long enough. A voltage drop I could not find my USB meter.
The plastic housing feels very comfortable to the skin. The device has a weight of approximately 180 grams. The chassis connectors are very stable and flush-mounted in the housing. Nothing wobbles, all integrated very clean and flush. I have found no gap in the overall housing. Note that Power Bank can not be opened. So not replace the built-in battery possible.
The remaining battery time is displayed via a 4 line, backlit, blue LED chain. The LED plastic cover is matte white. Lighting the blue LED's on, which is not disturbing. Because it hides nothing, they are not Sauhell. The Power Bank you can even recharge at night in the bedroom.
The charging Endladeelektronik power bank is designed besonderst quickly. If a mobile phone or tablet connected for charging, there is no short-term power fluctuations during charging. I did with some other low loader already repeatedly remeasuring can. Remeasured I have a USB instrument. Furthermore, the iSmart to begin telling technique. What is it? Now, in the iSmart - technology is the charge current automatically to the consumer (mobile) adapted. This achieves, inter alia, a fastest charging. Also, it should not overheat in this technique. Also I have to check it in multiple test.
Something technology:
The 2.4 amp charging current can be called without exaggeration Power. All devices tested were automatically detected by the Power Bank and fully charged up to 100%. After charging the Power Bank is automatically turned off, thereby preventing overcharging. Minor drawback, the mobile phone, however, by switching off the charging voltage is not supplied with a so-called trickle charge. Switching to a timed trickle charge would be more appropriate in my opinion. And possibly at the price justified.
Charging the RavPower bank takes with 2.4 amps for about 4 hours. I have used for the 4-Port USB Charger RAVPower. I've also tested and described here on Amazon. Unfortunately, the Power Bank is not charging adapter (charger). The one should have in any case already or order them.
I tested the Power Bank with:
Smartphone - LG L70 (2100 mAh battery) - at a charge current of 0.69 amperes
Smartphone - Cubot X6 (2,200 mAh battery) - at a charge current of 0.94 amperes
Samsung GT - S5570 (1200 mAh battery) - at a charge current of 0.45 amperes
Asus Tablet - ME301T (4300 mAh battery) - at a charge current 1.14 amps
Conclusion: With all the products of RAVPower I'm so far always been very satisfied. Even with this battery charger you can not go absolutely wrong. So with a clear conscience I give a buy recommendation. I'll use in the future other products by RAVPower.
Maybe you have availed my review or favor and reward me with a YES for the usefulness of my work.
