It's an interesting product. The meter is the same exact meter as the ET900. My main complaint is the load tester, which is why I purchased the item. It can only test at the loads indicated, nothing in between. So: if the power supply can put out 2A, it'll say "PASS" but if it can put out 2.5A, it will just turn off when you try to run 3A tests, it will no tell you the actual output capability. This is a lot less useful than it seems.
Great little tool that does exactly what I need: measure the voltage and current (useful for evaluate charging cord); AND evaluate the capability of charger (i.e. if a charger can do quick charge with 3A or not). Excellent value!
