We currently sell a steel charging locker with an ETL Listed USB power strip which we recently encountered an issue with and would like to please ask for your recommendation on how to go about testing this item to determine what may have caused the problem along with requesting a quote. We have sold several hundred of these units over the past year without issue, but recently a customer of ours contacted us after roughly 3 of their units apparently failed, including instances of an Apple Lightning Cable which was in contact with the side wall of the steel locker shorting out and causing a visible burn mark on both the cable and housing. The other USB cells continued to function. The power strip includes 12 outlet USB with 110V / 15A imput and 5V / 2A output. We tested one of the units internally and could not replicate the problem, although a voltmeter showed that the cell was no longer delivering any power. Upon opening the power strip we could not find any signs of failure, no scorch marks, no melted wire coating, and even the LED on the bad port continued to function properly. We would like to send the remaining affected units for diagnostic testing to see what could have possibly caused this problem and if it was an issue connected to the unit itself or the power source our customer was using. We can send functional units as well for comparison.

Hello Sir/Madam, I am Anthony Perera from Sri Lanka and I have multiple degrees on Engineering field. Why you should hire me ? * I am a FULL TIME freelancer and once a project is awarded to me,all my time will be dedicated to that specific project so you will get fast and quality work. * I have been in the field of product designing so if you are developing a commercial device I can help you to design it at very low cost and also can get into contact with Chinese manufacturers who I work with. Very reliable and fast. * I have my own PCB printing facility and also a workshop where I can design and manufacture any number of samples/prototypes. In that way you don't have to find some one else to test my work. * My prices are very fair and can be negotiated all the time. I am very flexible and very understanding. You can see my reviews. Check my profile. See for your self. https://www.freelancer.com/u/Anthony989.html I need to know the what type of charger you are using. SDP, CDP or DCP. What is the controller IC and what is the battery management IC. I have been designing battery charges and USB chargers for years. And I think I have enough experience to resolve your matter. Thank you Anthony Perera
