For charging batteries AAA or AA me a display would not have mattered, for loading 18650 Li-ion batteries can I find the display, however, a very meaningful thing. This shows the current during the charging voltage and the charged capacity. With the latter for feature allows new battery check with regard to their capacity. For the complete capacity test there the CAP function that it discharges the battery once and then fully vollädt again.
Many other reviewers have the beep at this charger criticized the sounds 3 times when a battery is fully charged. 4 batteries charged, there at the end of a nice beep concert. I am of a different opinion and do not see this as a criticism. Li-ion batteries of high capacity are not toys and can wreak in a malpractice or a technical defect quite nice damage (examples there via Google enough). Even if the charger when it reaches the maximum voltage automatically stop charging finished batteries should not linger unnecessarily loader but be removed - By this the beep reminds reliable.
But criticism I would like to practice on the power supply. Actually, make it so far the vast majority of manufacturers of electrical appliances, which are operated with power supply, accompanied by a INTERTEK / GS power supply. This identifier indicates that the PSU has been tested by an independent body with respect to its security. In the enclosed power supply such labeling exists completely, there is not even a CE mark. A GS-certified power supply should at the price in my opinion, be in it. However, since I load only during the day in the presence of, I'm going to pull this no star.
Overall, I am very satisfied and the loader performs been reliably serving.
